│       └── public/
│           └── index.php
└── mysql/
    └── data/   # MySQL data (optional)

### Step 1: `docker-compose.yml`

Create a `docker-compose.yml` file:

version: '3.8'

services:
  nginx:
    image: nginx:latest
    container_name: nginx
    ports:
      - "80:80"
    volumes:
      - ./nginx:/etc/nginx/conf.d
      - ./sites/site1/public:/var/www/site1
      - ./sites/site2/public:/var/www/site2
    depends_on:
      - php

  php:
    build:
      context: ./php
    container_name: php
    volumes:
      - ./sites/site1/public:/var/www/site1
      - ./sites/site2/public:/var/www/site2
    expose:
      - "9000"

  mysql:
    image: mysql:8.0
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site1_db
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - ./mysql/data:/var/lib/mysql
    ports:
      - "3306:3306"

### Step 2: Nginx Configuration

Create individual Nginx configuration files for each site.

#### `nginx/site1.conf`

server {
    listen 80;
    server_name site1.localhost;
    root /var/www/site1;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    error_log  /var/log/nginx/site1_error.log;
    access_log /var/log/nginx/site1_access.log;
}

#### `nginx/site2.conf`

server {
    listen 80;
    server_name site2.localhost;
    root /var/www/site2;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    error_log  /var/log/nginx/site2_error.log;
    access_log /var/log/nginx/site2_access.log;
}

### Step 3: PHP Dockerfile

Create a Dockerfile for PHP 8.

#### `php/Dockerfile`

FROM php:8.2-fpm

# Install common PHP extensions
RUN apt-get update && apt-get install -y 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev 
    && docker-php-ext-install pdo pdo_mysql zip gd

# Set working directory
WORKDIR /var/www

### Step 4: Create Sample PHP Files

Create sample `index.php` files for each site.

#### `sites/site1/public/index.php`

<?php
echo "<h1>Welcome to Site 1</h1>";

#### `sites/site2/public/index.php`

<?php
echo "<h1>Welcome to Site 2</h1>";

### Step 5: Update Hosts File

For local testing, update your `/etc/hosts` file (on Windows: `C:WindowsSystem32driversetchosts`) with:

127.0.0.1 site1.localhost
127.0.0.1 site2.localhost

### Step 6: Build and Run Docker Containers

Run the following commands in the `docker-multiple-sites` directory:

docker-compose up --build -d

– Access `http://site1.localhost` to see **Site 1**.
– Access `http://site2.localhost` to see **Site 2**.

### Step 7: Check Container Status

You can verify that your containers are running:

docker-compose ps

### Step 8: Logs and Debugging

Check logs if you face any issues:

docker logs nginx
docker logs php
docker logs mysql

### Notes
– This setup assumes the use of MySQL. If your project doesn’t need a database, you can omit the MySQL service.
– You can add more sites by creating additional Nginx configuration files and corresponding directories under `sites/`.

This setup should allow you to run multiple PHP-based sites on a single Docker environment using Nginx and PHP-FPM.

### Updated Directory Structure

    └── data/   # MySQL data (optional)

### Step 1: Update `docker-compose.yml`

Here's the updated `docker-compose.yml` to include services for Composer and Node.js:

version: '3.8'

services:
  nginx:
    image: nginx:latest
    container_name: nginx
    ports:
      - "80:80"
    volumes:
      - ./nginx:/etc/nginx/conf.d
      - ./sites/site1/public:/var/www/site1
      - ./sites/site2/public:/var/www/site2
    depends_on:
      - php

  php:
    build:
      context: ./php
    container_name: php
    volumes:
      - ./sites/site1:/var/www/site1
      - ./sites/site2:/var/www/site2
    expose:
      - "9000"
    working_dir: /var/www/site1
    command: bash -c "composer install && php-fpm"

  mysql:
    image: mysql:8.0
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site1_db
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - ./mysql/data:/var/lib/mysql
    ports:
      - "3306:3306"

  node:
    image: node:18-alpine
    container_name: node
    working_dir: /var/www/site1
    volumes:
      - ./sites/site1:/var/www/site1
      - ./sites/site2:/var/www/site2
    command: bash -c "yarn install && yarn dev"
    depends_on:
      - php

### Step 2: Update PHP Dockerfile (`php/Dockerfile`)

#### `php/Dockerfile`

FROM php:8.2-fpm

# Install system dependencies
RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev 
    && docker-php-ext-install pdo pdo_mysql zip gd

# Install Composer
COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

# Set working directory
WORKDIR /var/www

### Step 3: Create Sample `composer.json`, `package.json`, and Frontend Files

Add the `composer.json` and `package.json` files for each site.

#### `sites/site1/composer.json`

{
  "name": "site1/project",
  "require": {
    "php": "^8.2",
    "vlucas/phpdotenv": "^5.5"
  }
}

#### `sites/site1/package.json`

{
  "name": "site1",
  "version": "1.0.0",
  "scripts": {
    "dev": "vite",
    "build": "vite build"
  },
  "dependencies": {
    "vite": "^4.0.0",
    "vue": "^3.2.0"
  }
}

#### `sites/site1/public/index.php`

<?php
require __DIR__ . '/../vendor/autoload.php';
echo "<h1>Welcome to Site 1 with Composer & Yarn</h1>";

#### `sites/site2/composer.json`

{
  "name": "site2/project",
  "require": {
    "php": "^8.2",
    "guzzlehttp/guzzle": "^7.7"
  }
}

#### `sites/site2/package.json`

{
  "name": "site2",
  "version": "1.0.0",
  "scripts": {
    "dev": "vite",
    "build": "vite build"
  },
  "dependencies": {
    "vite": "^4.0.0",
    "react": "^18.0.0",
    "react-dom": "^18.0.0"
  }
}

### Step 4: Nginx Configuration for Vite

Make sure to update your Nginx configurations to handle Vite's hot-reloading in development mode.

#### `nginx/site1.conf`

server {
    listen 80;
    server_name site1.localhost;
    root /var/www/site1/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass php:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location /_vite {
        proxy_pass http://node:5173;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
    }
}

### Step 5: Build and Run Docker Containers

Run the following commands to start everything:

docker-compose down --remove-orphans
docker-compose up --build -d

– Run Composer in PHP container:

docker exec -it php composer install

– Run Yarn in Node container:

docker exec -it node yarn install
  docker exec -it node yarn dev

### Step 6: Access Your Sites

– **Site 1**: `http://site1.localhost`
– **Site 2**: `http://site2.localhost`

Make sure to update your `/etc/hosts` file:

127.0.0.1 site1.localhost
127.0.0.1 site2.localhost

### Notes
– You can adjust the `yarn dev` command if you use different frontend frameworks (e.g., React, Vue).
– The setup now includes Composer for PHP packages, Yarn, and Node.js for JavaScript dependencies.
– If you encounter permission issues, you might need to adjust ownership with `chown` or use Docker volumes properly.

### Updated `docker-compose.yml`

version: '3.8'

services:
  nginx:
    image: nginx:latest
    container_name: nginx
    ports:
      - "8081:80"  # Port for Site 1
      - "8082:81"  # Port for Site 2
    volumes:
      - ./nginx:/etc/nginx/conf.d
      - ./sites/site1/public:/var/www/site1
      - ./sites/site2/public:/var/www/site2
    depends_on:
      - php

  php:
    build:
      context: ./php
    container_name: php
    volumes:
      - ./sites/site1:/var/www/site1
      - ./sites/site2:/var/www/site2
    expose:
      - "9000"
    working_dir: /var/www/site1

  mysql:
    image: mysql:8.0
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site1_db
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - ./mysql/data:/var/lib/mysql
    ports:
      - "3306:3306"

  node:
    image: node:18-alpine
    container_name: node
    working_dir: /var/www/site1
    volumes:
      - ./sites/site1:/var/www/site1
      - ./sites/site2:/var/www/site2
    command: bash -c "yarn install && yarn dev"
    depends_on:
      - php

### Nginx Configuration

#### `nginx/site1.conf`

server {
    listen 80;
    server_name localhost;
    root /var/www/site1/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass php:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location /_vite {
        proxy_pass http://node:5173;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
    }

    error_log  /var/log/nginx/site1_error.log;
    access_log /var/log/nginx/site1_access.log;
}

#### `nginx/site2.conf`

server {
    listen 81; # Port 81 for Site 2
    server_name localhost;
    root /var/www/site2/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass php:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location /_vite {
        proxy_pass http://node:5173;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
    }

    error_log  /var/log/nginx/site2_error.log;
    access_log /var/log/nginx/site2_access.log;
}

### Accessing Sites

– **Site 1**: Open [http://localhost:8081](http://localhost:8081)
– **Site 2**: Open [http://localhost:8082](http://localhost:8082)

### Step 3: Build and Run Containers

docker-compose down --remove-orphans
docker-compose up --build -d

### Notes
– This configuration uses different external ports (`8081` and `8082`) mapped to the internal Nginx ports (`80` and `81`).
– Now, you can access each site using a port number without needing to modify the `/etc/hosts` file.
– The Node.js container is set up for Vite. Ensure your `vite.config.js` is configured to accept connections from Docker. Here's an example:

#### `vite.config.js`

export default {
  server: {
    host: '0.0.0.0',
    port: 5173,
    watch: {
      usePolling: true,
    },
  },
};

This approach keeps your setup flexible, and you can scale it to add more sites by assigning different ports as needed.

### Step 1: `docker-compose.yml`

Here's the updated `docker-compose.yml` to support multiple PHP versions:

version: '3.8'

services:
  nginx:
    image: nginx:latest
    container_name: nginx
    ports:
      - "8081:80"  # Port for Site 1
      - "8082:81"  # Port for Site 2
    volumes:
      - ./nginx:/etc/nginx/conf.d
      - ./sites/site1/public:/var/www/site1
      - ./sites/site2/public:/var/www/site2
    depends_on:
      - php7.4
      - php8.2

  php7.4:
    build:
      context: ./php/php7.4
    container_name: php7.4
    volumes:
      - ./sites/site1:/var/www/site1
    expose:
      - "9074"

  php8.2:
    build:
      context: ./php/php8.2
    container_name: php8.2
    volumes:
      - ./sites/site2:/var/www/site2
    expose:
      - "9082"

  mysql:
    image: mysql:8.0
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site_db
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - ./mysql/data:/var/lib/mysql
    ports:
      - "3306:3306"

  node:
    image: node:18-alpine
    container_name: node
    working_dir: /var/www/site1
    volumes:
      - ./sites/site1:/var/www/site1
      - ./sites/site2:/var/www/site2
    command: bash -c "yarn install && yarn dev"
    depends_on:
      - php8.2
      - php7.4

### Step 2: PHP Dockerfiles

#### `php/php7.4/Dockerfile`

FROM php:7.4-fpm

RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev 
    && docker-php-ext-install pdo pdo_mysql zip gd

COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

WORKDIR /var/www

#### `php/php8.2/Dockerfile`

FROM php:8.2-fpm

RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev 
    && docker-php-ext-install pdo pdo_mysql zip gd

COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

WORKDIR /var/www

### Step 3: Nginx Configuration

#### `nginx/site1.conf`

server {
    listen 80;
    server_name localhost;
    root /var/www/site1/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass php7.4:9074;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    error_log  /var/log/nginx/site1_error.log;
    access_log /var/log/nginx/site1_access.log;
}

#### `nginx/site2.conf`

server {
    listen 81;
    server_name localhost;
    root /var/www/site2/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass php8.2:9082;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    error_log  /var/log/nginx/site2_error.log;
    access_log /var/log/nginx/site2_access.log;
}

### Step 4: Sample PHP Files

#### `sites/site1/public/index.php` (Using PHP 7.4)

<?php
echo "<h1>Welcome to Site 1 (PHP 7.4)</h1>";
phpinfo();

#### `sites/site2/public/index.php` (Using PHP 8.2)

<?php
echo "<h1>Welcome to Site 2 (PHP 8.2)</h1>";
phpinfo();

### Step 5: Build and Run Docker Containers

Run the following commands:

docker-compose down --remove-orphans
docker-compose up --build -d

### Step 6: Access the Sites

– **Site 1 (PHP 7.4)**: [http://localhost:8081](http://localhost:8081)
– **Site 2 (PHP 8.2)**: [http://localhost:8082](http://localhost:8082)

### Step 7: Checking Logs

To view logs for each service:

docker logs nginx
docker logs php7.4
docker logs php8.2

### Notes
– You can scale this setup to include more sites and different PHP versions by adding new services in `docker-compose.yml` and creating corresponding Dockerfiles.
– This configuration uses different internal ports (`9074` for PHP 7.4 and `9082` for PHP 8.2) to ensure proper routing by Nginx.
– Make sure to adjust the firewall or security rules on your local machine if necessary to access the assigned ports.

### Step 1: Directory Structure

Update your directory structure to include `php.ini` files:

docker-multiple-sites/
├── docker-compose.yml
├── nginx/
│   ├── site1.conf
│   └── site2.conf
├── php/
│   ├── php7.4/
│   │   ├── Dockerfile
│   │   └── php.ini
│   └── php8.2/
│       ├── Dockerfile
│       └── php.ini
├── sites/
│   ├── site1/
│   │   └── public/
│   │       └── index.php
│   └── site2/
│       └── public/
│           └── index.php
└── mysql/
    └── data/

### Step 2: Create `php.ini` Files

#### `php/php7.4/php.ini`

; PHP 7.4 Configuration

display_errors = On
display_startup_errors = On
error_reporting = E_ALL
memory_limit = 256M
upload_max_filesize = 50M
post_max_size = 50M
max_execution_time = 300
date.timezone = "UTC"

#### `php/php8.2/php.ini`

; PHP 8.2 Configuration

display_errors = On
display_startup_errors = On
error_reporting = E_ALL
memory_limit = 512M
upload_max_filesize = 100M
post_max_size = 100M
max_execution_time = 300
date.timezone = "UTC"

### Step 3: Update PHP Dockerfiles

#### `php/php7.4/Dockerfile`

FROM php:7.4-fpm

# Install system dependencies
RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev 
    && docker-php-ext-install pdo pdo_mysql zip gd

# Copy Composer
COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

# Copy custom php.ini
COPY php.ini /usr/local/etc/php/php.ini

WORKDIR /var/www

#### `php/php8.2/Dockerfile`

FROM php:8.2-fpm

# Install system dependencies
RUN apt-get update && apt-get install -y

### Step 4: Build and Run Docker Containers

After setting up your `php.ini` files and Dockerfiles, run the following commands:

docker-compose down --remove-orphans
docker-compose up --build -d

### Step 5: Verify the Configuration

To confirm that the correct `php.ini` file is being used, you can add a PHP info page to each site.

#### `sites/site1/public/index.php`

<?php
echo "<h1>Site 1 (PHP 7.4)</h1>";
phpinfo();

#### `sites/site2/public/index.php`

<?php
echo "<h1>Site 2 (PHP 8.2)</h1>";
phpinfo();

### Access the Sites

– **Site 1 (PHP 7.4)**: [http://localhost:8081](http://localhost:8081)
– **Site 2 (PHP 8.2)**: [http://localhost:8082](http://localhost:8082)

Check the `Loaded Configuration File` section on the PHP info page to verify that your custom `php.ini` file is loaded.

### Step 6: Reload the Containers (if needed)

If you make changes to the `php.ini` files and want to apply them:

docker-compose restart php7.4 php8.2

This approach allows each PHP version to have its own configuration, ensuring that each site can use specific settings tailored to its requirements.

### `docker restart` Command

The basic usage of the `docker restart` command is:

docker restart [OPTIONS] CONTAINER [CONTAINER...]

– **CONTAINER**: The name or ID of the container you want to restart.
– **OPTIONS**: Additional options, such as `-t` to specify the timeout before forcibly stopping the container.

### Examples

1. **Restart a single container**:

docker restart php7.4

This command will restart the container named `php7.4`.

2. **Restart multiple containers**:

docker restart php7.4 php8.2

This will restart both `php7.4` and `php8.2` containers.

3. **Restart all running containers**:

If you want to restart all running containers, you can use:

docker restart $(docker ps -q)

– `docker ps -q` lists the IDs of all running containers.
– The `$(…)` syntax passes that list of IDs to the `docker restart` command.

### `docker-compose restart`

If you're using `docker-compose`, you can restart containers defined in your `docker-compose.yml` file with:

docker-compose restart

You can also specify individual services:

docker-compose restart php7.4 php8.2

### When to Use `docker restart`

– **Config Changes**: If you update configuration files like `php.ini`, `nginx.conf`, or environment variables, restarting the container is necessary for changes to take effect.
– **Memory Issues**: If your container is consuming too much memory or has become unresponsive, a restart can clear up resources.
– **Debugging**: Restarting is useful if you're troubleshooting issues and want to see if a fresh start resolves the problem.

### `docker-compose up` vs. `docker restart`

– `docker restart` only stops and starts containers without rebuilding images or applying changes to your `docker-compose.yml` file.
– `docker-compose up –build -d` will recreate containers, apply any changes in your configuration, and run them in detached mode. This is useful if you've made updates to your Dockerfiles, `docker-compose.yml`, or the build context.

Use `docker restart` for quick restarts, and `docker-compose up –build` if you've changed your Docker configuration or files that require rebuilding.

### Restart Policy Options
– **`no`** (default): Do not automatically restart the container. It only starts the container when explicitly run.
– **`always`**: Always restart the container if it stops, regardless of the exit status.
– **`on-failure`**: Restart the container only if it exits with a non-zero exit code (i.e., it failed).
– **`unless-stopped`**: Always restart the container unless it is explicitly stopped by the user.

### Example `docker-compose.yml` with Restart Policies

Here's an example of how to use the `restart` policy in your `docker-compose.yml` file:

version: '3.8'

services:
  nginx:
    image: nginx:latest
    container_name: nginx
    ports:
      - "8081:80"
      - "8082:81"
    volumes:
      - ./nginx:/etc/nginx/conf.d
      - ./sites/site1/public:/var/www/site1
      - ./sites/site2/public:/var/www/site2
    depends_on:
      - php7.4
      - php8.2
    restart: always

  php7.4:
    build:
      context: ./php/php7.4
    container_name: php7.4
    volumes:
      - ./sites/site1:/var/www/site1
    expose:
      - "9074"
    restart: on-failure

  php8.2:
    build:
      context: ./php/php8.2
    container_name: php8.2
    volumes:
      - ./sites/site2:/var/www/site2
    expose:
      - "9082"
    restart: unless-stopped

  mysql:
    image: mysql:8.0
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site_db
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - ./mysql/data:/var/lib/mysql
    ports:
      - "3306:3306"
    restart: always

  node:
    image: node:18-alpine
    container_name: node
    working_dir: /var/www/site1
    volumes:
      - ./sites/site1:/var/www/site1
      - ./sites/site2:/var/www/site2
    command: bash -c "yarn install && yarn dev"
    depends_on:
      - php8.2
      - php7.4
    restart: on-failure

### Explanation of Policies in the Example
– **nginx**: Uses `restart: always`, so it will restart every time it stops, even if stopped manually.
– **php7.4**: Uses `restart: on-failure`, which means it will only restart if it exits with a non-zero exit code.
– **php8.2**: Uses `restart: unless-stopped`, which means it will restart unless explicitly stopped by the user.
– **mysql**: Also uses `restart: always` to ensure high availability.
– **node**: Uses `restart: on-failure` for development environments where you want the container to restart only on errors.

### How to Apply Changes

After adding or updating the restart policies, make sure to run:

docker-compose down
docker-compose up -d

This ensures that Docker applies the new restart policies to your containers.

### Use Cases for Each Policy
– **`no`**: Use this when you don't want your container to restart automatically (e.g., for one-off tasks).
– **`always`**: Ideal for production environments where you want your services to be highly available.
– **`on-failure`**: Useful for development environments to automatically recover from unexpected errors.
– **`unless-stopped`**: Good for services that should run continuously but can be stopped manually without being restarted automatically.

Choose the restart policy that best fits the behavior you want for each service.

ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for services.php: 'olimysql'

indicates that there is a typo or misconfiguration in your `docker-compose.yml` file. The error suggests that a service named `php` is mistakenly referencing an unsupported option `olimysql`, which is not a valid configuration key in Docker Compose.

### Possible Causes
1. **Typo in the Service Definition**: You might have accidentally added `olimysql` as a configuration key under the `php` service.
2. **Incorrect Service Reference**: You may be trying to define a `depends_on` or link to a service called `olimysql` that is either not defined or misplaced.

### How to Fix It
To resolve this issue, let's review a few steps to correct your `docker-compose.yml` file:

#### Step 1: Check Your `docker-compose.yml` for Errors
Make sure your services are correctly defined and there are no misplaced configuration options. Here's a corrected example of a typical `docker-compose.yml` setup for multiple PHP versions:

version: '3.8'

services:
  nginx:
    image: nginx:latest
    container_name: nginx
    ports:
      - "8081:80"
      - "8082:81"
    volumes:
      - ./nginx:/etc/nginx/conf.d
      - ./sites/site1/public:/var/www/site1
      - ./sites/site2/public:/var/www/site2
    depends_on:
      - php7.4
      - php8.2
    restart: always

  php7.4:
    build:
      context: ./php/php7.4
    container_name: php7.4
    volumes:
      - ./sites/site1:/var/www/site1
    expose:
      - "9074"
    restart: on-failure

  php8.2:
    build:
      context: ./php/php8.2
    container_name: php8.2
    volumes:
      - ./sites/site2:/var/www/site2
    expose:
      - "9082"
    restart: unless-stopped

  mysql:
    image: mysql:8.0
    container_name: mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site_db
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - ./mysql/data:/var/lib/mysql
    ports:
      - "3306:3306"
    restart: always

  node:
    image: node:18-alpine
    container_name: node
    working_dir: /var/www/site1
    volumes:
      - ./sites/site1:/var/www/site1
      - ./sites/site2:/var/www/site2
    command: bash -c "yarn install && yarn dev"
    depends_on:
      - php7.4
      - php8.2
    restart: on-failure

### Step 2: Validate Your Docker Compose File
You can use the following command to check for syntax errors:

docker-compose config

If your `docker-compose.yml` file is valid, this command will print a normalized version of it. If there are any errors, it will display helpful messages.

### Step 3: Restart Your Docker Compose Setup
If you've made corrections, restart your setup:

docker-compose down --remove-orphans
docker-compose up -d --build

### Common Pitfalls to Check
– Ensure that all service names (like `php7.4`, `php8.2`, and `mysql`) are correctly spelled and referenced.
– Make sure that there are no indentation issues or misplaced configuration keys.
– Verify that each service is using supported configuration options for your specified Docker Compose version.

These adjustments should help resolve the `Unsupported config option` error you're encountering.

Error response from daemon: You cannot remove a running container 596c1a493757203c274fc0a68bd2608d0dd06254d6caf103855e9a4c2b67781f. Stop the container before attempting removal or force remove

indicates that Docker is trying to remove a container that is currently running. To delete a running container, you need to stop it first or forcefully remove it.

Here are the steps you can take to resolve this issue:

### Option 1: Stop and Remove the Container

1. **Stop the container**:

docker stop 596c1a493757

2. **Remove the container**:

docker rm 596c1a493757

Replace `596c1a493757` with the full or partial container ID shown in your error message.

### Option 2: Force Remove the Container (if you don't want to stop it first)

If you want to remove the container immediately, even if it is running, you can use the `-f` (force) option:

docker rm -f 596c1a493757

This command will stop the container (if it's running) and then remove it.

### Option 3: Use `docker-compose` Commands (if you are using Docker Compose)

If your container is part of a Docker Compose setup, use the following commands:

1. **Stop all running containers defined in your `docker-compose.yml`**:

docker-compose down

This command stops and removes all containers, networks, and volumes defined in the `docker-compose.yml`.

2. **If you only want to stop specific services**:

docker-compose stop servicename

3. **Remove stopped containers, networks, and volumes (optional)**:

docker-compose rm -f

### Option 4: List All Containers and Clean Up

If you want to clean up all unused containers, networks, and images, use:

# Stop all running containers
docker stop $(docker ps -q)

# Remove all stopped containers
docker container prune -f

Alternatively, to clean up everything (including networks and images not in use):

docker system prune -a -f

This will remove **all** unused containers, images, and networks, so use it with caution.

These commands should help you resolve the issue by either stopping and removing the specific container or cleaning up your Docker environment.

    networks:
      - oliver-app-network
    restart: on-failure

networks:
  oliver-app-network:
    driver: bridge

### Key Changes and Fixes:

1. **Fixed Service Names**:
– The error `Unsupported config option for services.php: 'olimysql'` was due to misalignment in indentation. Make sure each service (like `php`, `olimysql`, etc.) is correctly defined under `services`.

2. **Network Configuration**:
– Ensured that all services are using the same custom network `oliver-app-network`.

3. **Expose vs. Ports**:
– The `php` service is using `expose` to make port `9000` available to other services within the Docker network, which is fine. The Nginx service listens on `80` internally and exposes it to `3500` on the host.

4. **Removed Invalid YAML Syntax**:
– The line `http://localhost:3500/` at the end of your original file is not valid YAML and has been removed.

### Applying Changes

After updating the `docker-compose.yml` file, make sure to rebuild and restart your services:

# Stop and remove existing containers
docker-compose down

# Rebuild and start containers
docker-compose up -d --build

### Troubleshooting Tips

1. **Check Container Logs**:
– To see what's happening inside your containers, use:

docker-compose logs nginx
     docker-compose logs php
     docker-compose logs olimysql

2. **Verify Network Connectivity**:
– Ensure all services are connected to the correct network:

docker network inspect oliver-app-network

3. **Check Nginx Configuration**:
– If you are using a custom `nginx.conf`, make sure it correctly points to the `php` service. For example, in your `nginx.conf` file:

server {
         listen 80;
         server_name localhost;

         root /var/www/all4cloud-wordpress-website;
         index index.php index.html index.htm;

         location / {
             try_files $uri $uri/ /index.php?$query_string;
         }

         location ~ .php$ {
             fastcgi_pass oliver-php:9000;
             fastcgi_index index.php;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             include fastcgi_params;
         }
     }

4. **Access the Application**:
– Once everything is up, open your browser and go to:

http://localhost:3500/

– For Adminer:

http://localhost:3501/

This setup should resolve the issue and get your site running correctly on port `3500`.

### Step 1: Check Nginx Container Logs
First, check the logs of your Nginx container to see if there are any errors:

docker-compose logs nginx

Look for any error messages related to configuration issues, missing files, or permission problems.

### Step 2: Verify Nginx Configuration
Make sure your Nginx configuration file (`nginx.conf`) is correctly set up. Here's an example of a typical `nginx.conf` for serving a PHP application:

**`nginx/nginx.conf`**:

server {
    listen 80;
    server_name localhost;

    root /var/www/all4cloud-wordpress-website;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ .php$ {
        fastcgi_pass oliver-php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    error_log /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
}

Make sure that:
– The `root` directive points to the correct directory (`/var/www/all4cloud-wordpress-website`).
– The `fastcgi_pass` directive uses the correct service name (`oliver-php`) and port (`9000`).
– The PHP service is correctly named `oliver-php` and is exposing port `9000`.

### Step 3: Rebuild Your Nginx Container
If you've made changes to your Nginx configuration, you'll need to rebuild the container:

docker-compose down
docker-compose up -d --build

### Step 4: Verify the Volumes
Ensure that the volume mappings are correct in your `docker-compose.yml` file. The Nginx container should have access to the website files:

volumes:
  - ./nginx:/etc/nginx/conf.d
  - ./nginx/nginx.conf:/etc/nginx/nginx.conf
  - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website

### Step 5: Check Container Status
Verify that all your containers are running:

docker-compose ps

The output should indicate that all services, including `nginx`, are up and running. If Nginx is not listed, try starting it manually:

docker-compose up -d nginx

### Step 6: Inspect Nginx Network Connectivity
Ensure that Nginx can communicate with the PHP service:

docker exec -it oliver-nginx ping oliver-php

If the ping is successful, the network setup is correct. If not, there may be a network configuration issue.

### Step 7: Test Nginx Configuration Inside the Container
You can also test the Nginx configuration directly inside the container:

docker exec -it oliver-nginx nginx -t

If there are any errors in your Nginx configuration, this command will display them.

### Step 8: Verify Ports
Make sure that port `3500` is not being used by another service on your host machine. You can check which services are using ports with:

sudo lsof -i :3500

If another service is using this port, either stop that service or change the port mapping in your `docker-compose.yml`.

### Step 9: Restart Docker Service (if necessary)
Sometimes, Docker itself may have issues. Restarting the Docker service can help:

# On Linux
sudo systemctl restart docker

# On Windows (if using Docker Desktop)
Restart Docker Desktop from the system tray.

After trying the above steps, go to your browser and test:

http://localhost:3500/

These steps should help you identify and resolve the issue with Nginx not showing up. Let me know if you encounter any specific errors during these steps!

– **Containers Stopped and Removed**:
– `oliver-adminer`
– `oliver-nginx`
– `oliver-node`
– `oliver-php`
– `oliver-mysql`

– **Networks Removed**:
– `dedicated-oliver_oliver-app-network`
– `dedicated-oliver_default`

This indicates that your Docker setup was properly brought down using:

docker-compose down

However, since you also lost the networks, let's ensure your setup is ready to be brought back up. Here's what you should do next.

### Step 1: Bring Your Containers Back Up
Since the networks were also removed, you need to bring everything back up, which will recreate the networks:

docker-compose up -d --build

This command will:
– **Rebuild** the images (in case there were changes).
– **Recreate** the containers.
– **Recreate the networks** (like `oliver-app-network`).

### Step 2: Verify the Containers and Networks
Check if all your containers are running properly:

docker-compose ps

Ensure that all services are `Up` and running. Then, inspect the network to ensure everything is connected properly:

docker network ls

If you want to inspect the details of the specific network (e.g., `oliver-app-network`), use:

docker network inspect oliver-app-network

### Step 3: Check Nginx Service
After everything is up, test if your Nginx service is accessible:

– Open your browser and navigate to:

http://localhost:3500/

– If it still doesn't work, check the logs for Nginx:

docker-compose logs nginx

### Step 4: Troubleshoot Common Issues
If you still face issues with Nginx not showing up:

1. **Check if Port 3500 is Already in Use**:

sudo lsof -i :3500

2. **Try Restarting Nginx**:

docker-compose restart nginx

3. **Manually Access Nginx Container**:

docker exec -it oliver-nginx bash

From inside the container, you can run:

nginx -t   # Test the configuration
   nginx -s reload  # Reload Nginx if needed

These steps should help you get your environment back up and resolve any issues with Nginx or other services. Let me know if you encounter specific errors, and I can provide further assistance!

Look for any error messages, especially those related to file paths, permissions, or configuration issues.

### Step 2: Verify Nginx Configuration File
Make sure your Nginx configuration (`nginx/nginx.conf`) is set up correctly. Here is an example of a typical Nginx configuration for PHP applications:

**`nginx/nginx.conf`**:

server {
    listen 80;
    server_name localhost;

    root /var/www/all4cloud-wordpress-website;
    index index.php index.html index.htm;

    # Handle static files
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    # Pass PHP scripts to the PHP-FPM container
    location ~ .php$ {
        include fastcgi_params;
        fastcgi_pass oliver-php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    # Access and error logs
    error_log /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
}

Make sure this file is correctly mounted inside the Nginx container:

volumes:
  - ./nginx/nginx.conf:/etc/nginx/nginx.conf

### Step 3: Test Nginx Configuration
After ensuring your `nginx.conf` is correct, you can test the Nginx configuration inside the container:

docker exec -it oliver-nginx nginx -t

If there are any configuration issues, this command will show them. If successful, reload Nginx:

docker exec -it oliver-nginx nginx -s reload

### Step 4: Verify Volumes and Permissions
Make sure your application files are accessible inside the Nginx and PHP containers:

1. **Check Nginx Container**:

docker exec -it oliver-nginx ls -l /var/www/all4cloud-wordpress-website

2. **Check PHP Container**:

docker exec -it oliver-php ls -l /var/www/all4cloud-wordpress-website

Ensure that the files are present and have the correct permissions.

### Step 5: Ensure Ports are Free
Make sure port `3500` is not being used by another service:

sudo lsof -i :3500

If another service is using this port, stop it or change the port mapping in your `docker-compose.yml`.

### Step 6: Rebuild and Restart Containers
Sometimes, old configurations might still be cached. Rebuild your containers to ensure all changes are applied:

docker-compose down
docker-compose up -d --build

### Step 7: Verify Containers and Network
Check if all your services are running correctly:

docker-compose ps

Make sure all services show up as `Up`. Also, verify that the network is properly set up:

docker network inspect oliver-app-network

### Step 8: Access the Site
After following all the steps above, try accessing:

http://localhost:3500

### Step 9: Debug with Curl (Optional)
If it's still not working, try using `curl` to debug from the host machine:

curl -I http://localhost:3500

Or from inside the Nginx container:

docker exec -it oliver-nginx curl -I http://localhost

This will give you more information on what might be failing (e.g., 404, 502 errors, etc.).

These steps should help identify and resolve the issue. Let me know what specific errors or logs you see if it still doesn't work!

Here's an updated version of your `docker-compose.yml` file without custom networks:

### Updated `docker-compose.yml`

version: '3.3'

services:
  nginx:
    image: nginx:latest
    container_name: oliver-nginx
    ports:
      - "3500:80"

### Explanation of Changes

1. **Removed Custom Networks**:
– Removed all `networks` configurations from the services.
– Removed the `networks` section at the bottom.

2. **Default Docker Network**:
– All services will now use Docker's default bridge network.
– Containers can communicate with each other using their service names (e.g., `oliver-php`, `oliver-mysql`).

### Step 1: Bring Down Existing Containers
First, bring down your existing setup:

docker-compose down

### Step 2: Clean Up Networks
Optionally, you can remove any existing custom networks to avoid conflicts:

docker network prune

### Step 3: Rebuild and Restart Containers
Bring everything back up with the updated configuration:

docker-compose up -d --build

### Step 4: Test the Setup
Now, check if everything is working:

– Nginx: [http://localhost:3500](http://localhost:3500)
– Adminer: [http://localhost:3501](http://localhost:3501)

This simplified setup should help eliminate any issues related to custom network configurations. Let me know if it resolves your issue!

### Step 1: Remove All Containers, Images, Volumes, and Networks
To ensure there are no leftover Docker resources that might cause conflicts, you can run the following commands:

1. **Stop and Remove All Containers**:

docker stop $(docker ps -aq)
   docker rm $(docker ps -aq)

2. **Remove All Networks** (including any custom networks):

docker network prune -f

3. **Remove All Unused Images** (if you want to free up space):

docker rmi $(docker images -q) -f

4. **Remove All Volumes**:

docker volume prune -f

### Step 2: Confirm Everything is Clean
You can confirm that everything has been removed by checking:

– **Containers**:

docker ps -a

– **Networks**:

docker network ls

– **Images**:

docker images

– **Volumes**:

docker volume ls

### Step 3: Rebuild Your Docker Environment
Once everything is clean, you can bring up your environment again:

1. Make sure your `docker-compose.yml` file is properly configured.

2. Then, run:

docker-compose up -d --build

### Step 4: Verify Your Services
Check if your services are running correctly:

docker-compose ps

### Step 5: Check Logs for Any Errors
If something still isn't working, check the logs of the specific service:

docker-compose logs nginx
docker-compose logs php
docker-compose logs olimysql
docker-compose logs adminer
docker-compose logs node

### Step 6: Test the Application
– Visit your site at [http://localhost:3500](http://localhost:3500).
– Check Adminer at [http://localhost:3501](http://localhost:3501).

These steps should help you fully reset and set up your Docker environment from scratch. Let me know if you run into any specific errors during this process!

Please check that the mysqli PHP extension is installed and enabled.

To resolve this, you need to install the required MySQL extension in your PHP container. Here's how you can do it:

### Step 1: Modify the Dockerfile for PHP
If you're using a custom PHP setup with a `Dockerfile` in the `php/` directory (as indicated by your `docker-compose.yml`), you can add the necessary installation of the `mysqli` extension.

1. **Locate your `Dockerfile`** inside the `php/` directory.

2. **Update the `Dockerfile` to install the required PHP extension**. For PHP 8.0 (or whatever version you're using), you can install `mysqli` using the following lines:

**Example `Dockerfile`**:

# Use the PHP 8.0 FPM image (or your PHP version)
   FROM php:8.0-fpm

   # Install dependencies and mysqli extension
   RUN apt-get update && apt-get install -y libpng-dev libjpeg-dev libfreetype6-dev 
       && docker-php-ext-configure gd --with-freetype --with-jpeg 
       && docker-php-ext-install gd mysqli pdo pdo_mysql

   # Install Composer (optional, if needed)
   RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

   # Set the working directory (optional)
   WORKDIR /var/www/html

This `Dockerfile` does the following:
– Installs the `mysqli` extension along with other required extensions like `pdo` and `pdo_mysql`.
– Installs any other dependencies that might be needed for your application (like `gd` for image processing).

3. **Rebuild your PHP container** after updating the `Dockerfile`:

docker-compose build php

### Step 2: Restart Containers
Once the rebuild is done, restart your containers:

docker-compose up -d

### Step 3: Verify the PHP Extensions
After rebuilding and restarting the PHP container, check if the `mysqli` extension is enabled:

1. **Enter the PHP container**:

docker exec -it oliver-php bash

2. **Check PHP info** by running:

php -m | grep mysqli

If `mysqli` is listed, the extension is installed correctly.

### Step 4: Test WordPress
Once the extension is installed and the container is restarted, try accessing your WordPress site again. The error about the missing `mysqli` extension should no longer appear.

Let me know if you run into any further issues!

### Step 1: Edit the Dockerfile

Locate the `Dockerfile` in the `php/` directory (as referenced in your `docker-compose.yml` file). Open it and modify it to include the installation of the `mysqli` extension.

Here's an example of how you can modify your `Dockerfile`:

**Example `Dockerfile`:**

# Use the official PHP 8.0 FPM image (or your specific PHP version)
FROM php:8.0-fpm

# Install system dependencies and PHP extensions
RUN apt-get update && apt-get install -y 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libmysqlclient-dev 
    && docker-php-ext-configure gd --with-freetype --with-jpeg 
    && docker-php-ext-install gd mysqli pdo pdo_mysql

# Install Composer (optional, if needed)
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# Set the working directory (optional)
WORKDIR /var/www/html

### Explanation of the Dockerfile

1. **Base Image**: The `FROM php:8.0-fpm` line specifies the base PHP image. Adjust this version if you're using a different version of PHP (e.g., `php:7.4-fpm` for PHP 7.4).

2. **Installing Dependencies**:
– `libmysqlclient-dev` is required to install the `mysqli` extension.
– `docker-php-ext-install mysqli` installs the `mysqli` extension along with `pdo` and `pdo_mysql` (optional but commonly needed by WordPress).

3. **Composer Installation**: If you're using Composer in your container (which is useful for managing PHP dependencies), the `RUN curl -sS https://getcomposer.org/installer | php` line installs Composer.

4. **Set the Working Directory**: The `WORKDIR` directive sets the working directory inside the container to `/var/www/html`, where your application code will be mounted (this is optional and can be adjusted as needed).

### Step 2: Rebuild the PHP Container

After updating the `Dockerfile`, you need to rebuild the PHP container to apply the changes:

1. Run the following command to rebuild the `php` service:

docker-compose build php

2. Once the build is complete, bring the containers back up:

docker-compose up -d

### Step 3: Verify the Extension is Installed

To confirm that the `mysqli` extension has been successfully installed and enabled:

1. **Access the PHP container**:

docker exec -it oliver-php bash

2. **Check for the `mysqli` extension**:

php -m | grep mysqli

If the `mysqli` extension is installed properly, you should see `mysqli` in the list of installed PHP modules.

### Step 4: Test WordPress

After restarting your containers, check your WordPress site at [http://localhost:3500](http://localhost:3500). The error about the missing `mysqli` extension should now be resolved.

Let me know if you run into any issues!

### Step 1: Update Dockerfile to Install OpenSSH

You need to install the OpenSSH server inside your Node.js container to allow SSH access.

**Example Dockerfile for Node.js**:

# Use Node.js image
FROM node:20-alpine

# Install OpenSSH server
RUN apk add --no-cache openssh

# Create a new user to avoid running as root
RUN adduser -D nodeuser

# Set the working directory
WORKDIR /var/www/all4cloud-wordpress-website

# Copy package.json and install dependencies
COPY package*.json ./
RUN yarn install

# Copy the rest of the application code
COPY . .

# Expose port for SSH
EXPOSE 22

# Set the user to run the container
USER nodeuser

# Command to start SSH server
CMD ["/usr/sbin/sshd", "-D"]

### Explanation:

– **Install OpenSSH**: The command `apk add –no-cache openssh` installs OpenSSH.
– **Create a User**: A non-root user `nodeuser` is created to avoid running the container as the root user.
– **Expose SSH Port**: `EXPOSE 22` makes the container's SSH port accessible.
– **Run SSH Server**: The command `CMD ["/usr/sbin/sshd", "-D"]` runs the SSH server in the foreground.

### Step 2: Update `docker-compose.yml`

Ensure your `docker-compose.yml` file exposes port 22 for SSH access.

**Example `docker-compose.yml` for Node.js service**:

version: '3.3'

services:
  node:
    build:
      context: ./node
    container_name: oliver-node
    working_dir: /var/www/all4cloud-wordpress-website
    volumes:
      - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website
    ports:
      - "3502:22"  # Expose SSH on port 3502
    command: bash -c "yarn install && yarn dev"
    restart: on-failure

This configuration exposes port `3502` of the container for SSH access (`3502:22` maps container port 22 to your host port 3502).

### Step 3: Rebuild the Docker Container

Rebuild your Docker container to apply the changes:

docker-compose build node
docker-compose up -d

### Step 4: Access the Container via SSH

Once the container is running, you can SSH into it using the following command:

ssh -p 3502 nodeuser@localhost

If you set up a password for `nodeuser` in your Dockerfile (or during setup), you will be prompted for it. If not, the SSH access might fail unless you configure SSH keys or provide a password for the `nodeuser`.

### Step 5: Run Node.js Inside the Container

After SSHing into the container, you can navigate to your application folder and manually start the Node.js application if needed:

cd /var/www/all4cloud-wordpress-website
yarn dev  # Or any other command you use to start Node.js

—

### Alternative: Use `docker exec` Instead of SSH

If you don't specifically need SSH, you can also use `docker exec` to access the running Node.js container:

docker exec -it oliver-node bash

This will open a shell inside the running container, and you can run commands like `yarn dev` or other commands without setting up SSH.

Let me know if you need further assistance!

Here's how you can troubleshoot and resolve the issue:

### Step 1: Check the Logs of the Node Container
To get more details about why the container exited with an error, you can check the logs:

docker-compose logs node

This will display the logs from the `oliver-node` container. Look for any error messages that may explain why it exited.

### Step 2: Access the Container's Shell
If the logs don't give you enough information, try to access the container's shell to debug further. Since the container exited, you'll need to restart it in interactive mode:

docker-compose run --rm node bash

This will start the `oliver-node` container and open a bash shell inside it. You can try running the commands manually to see where the problem lies.

### Step 3: Debug the Node.js Application

Once inside the container, try the following commands to debug:

1. **Check if dependencies are installed**:

yarn install

This will ensure that all dependencies are correctly installed. If there are any issues with the `yarn install` process, it will be shown here.

2. **Run the Node.js app manually**:

yarn dev

This will start the Node.js application in development mode. Look for any errors or warnings in the output.

### Step 4: Verify the Dockerfile and `docker-compose.yml` Configuration

Ensure your `Dockerfile` and `docker-compose.yml` are set up correctly. Specifically:

1. **Dockerfile**: Ensure all necessary dependencies are installed and the correct working directory is set.

Example Dockerfile:

FROM node:20-alpine

   # Install OpenSSH (optional)
   RUN apk add --no-cache openssh

   # Create a new user
   RUN adduser -D nodeuser

   # Set the working directory
   WORKDIR /var/www/all4cloud-wordpress-website

   # Copy package.json and install dependencies
   COPY package*.json ./
   RUN yarn install

   # Copy the rest of the application code
   COPY . .

   # Expose ports
   EXPOSE 3000 22

   # Start the app
   CMD ["yarn", "dev"]

2. **docker-compose.yml**: Make sure that the `node` service is correctly configured to run the Node.js application.

Example `docker-compose.yml`:

version: '3.3'

   services:
     node:
       build:
         context: ./node
       container_name: oliver-node
       working_dir: /var/www/all4cloud-wordpress-website
       volumes:
         - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website
       ports:
         - "3502:22"  # Expose SSH on port 3502
       command: bash -c "yarn install && yarn dev"  # Install dependencies and run the app
       restart: on-failure

### Step 5: Rebuild and Restart the Containers

After making any necessary changes to the `Dockerfile` or `docker-compose.yml`, rebuild the containers and restart them:

docker-compose down  # Stop and remove containers
docker-compose up --build -d  # Rebuild and start containers in detached mode

### Step 6: Monitor the Container Logs Again
After the containers have restarted, monitor the logs again to check if the issue has been resolved:

docker-compose logs node

If the error persists, you can provide the log output here, and I'll help you further debug the issue.

### Cause of the Error

In your `docker-compose.yml` file, the `command` directive is incorrectly trying to run a shell command with `bash` as part of the path. It should be running the `yarn install` and `yarn dev` commands, but it seems to be misinterpreting something as a file path.

### Step 1: Fix the Command in `docker-compose.yml`

Make sure that the `command` for your Node.js container is set up correctly. You want to execute `yarn install` and `yarn dev`, not run a shell script or file named `bash`. Here's the correct configuration:

node:
  image: node:20-alpine
  container_name: oliver-node
  working_dir: /var/www/all4cloud-wordpress-website
  volumes:
    - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website
  ports:
    - "3502:22"  # Expose SSH on port 3502
  command: "sh -c 'yarn install && yarn dev'"  # Run yarn install and then yarn dev
  restart: on-failure

### Explanation:

– The `command` directive in the `docker-compose.yml` file should run `yarn install && yarn dev` correctly.
– We use `sh -c` to ensure that both `yarn install` and `yarn dev` are executed as a single shell command. This also ensures the proper shell environment is used to execute the commands.

### Step 2: Rebuild and Restart the Containers

After making the changes, rebuild the containers and bring them back up:

docker-compose down  # Stop and remove containers
docker-compose up --build -d  # Rebuild and start containers in detached mode

### Step 3: Verify

Once the containers are running, check the logs to confirm that the container started without errors:

docker-compose logs node

If the container still fails or encounters any other issues, let me know the updated error message, and I'll help you troubleshoot further.

Here’s how you can adjust your `docker-compose.yml` file:

### Updated `docker-compose.yml` Without the `command`:

version: '3.3'

services:
  node:
    image: node:20-alpine
    container_name: oliver-node
    working_dir: /var/www/all4cloud-wordpress-website
    volumes:
      - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website
    ports:
      - "3502:22"  # Expose SSH on port 3502
    restart: on-failure

### Explanation:

– By removing the `command` directive, the container will run with the default behavior defined in the `node:20-alpine` image, which typically starts up a Node.js environment.
– You can manually run `yarn install` and `yarn dev` by entering the container if needed, or you can set them in a `Dockerfile` if you want them to execute automatically when the container starts.

### Step 1: Rebuild and Restart the Containers

After updating the `docker-compose.yml` file, make sure to rebuild the containers and restart them:

docker-compose down  # Stop and remove containers
docker-compose up --build -d  # Rebuild and start containers in detached mode

### Step 2: Access the Node Container and Run Commands Manually

If you want to run `yarn install` and `yarn dev` manually within the container, you can do so by accessing the container's shell:

docker-compose exec node sh

Once inside the container, you can manually run the following commands:

yarn install   # Install dependencies
yarn dev       # Start the development server

### Step 3: Verify the Logs

You can also monitor the logs to ensure the container starts correctly:

docker-compose logs node

This should resolve the error and start the container without needing a custom `command`. Let me know if you need any further assistance!

### Possible Causes for the Container Exiting with Code 0

1. **No long-running process**: The Node.js container might not be starting a long-running process like a web server or development server, which is why it exits immediately.

2. **Default behavior**: If there’s no command defined, the Node.js image will run the default command, which might not be a long-running one, causing the container to exit.

### Solution 1: Start a Long-Running Process (e.g., Development Server)

Ensure that the container runs a long-lived process like `yarn dev` (which runs a development server for Node.js apps) to keep the container alive.

Here’s how to modify your `docker-compose.yml` file to make sure the container stays up:

1. **Add a Command to Keep the Container Running**: You can modify the `command` to start `yarn dev` as a long-running process:

version: '3.3'

services:
  node:
    image: node:20-alpine
    container_name: oliver-node
    working_dir: /var/www/all4cloud-wordpress-website
    volumes:
      - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website
    ports:
      - "3502:22"  # Expose SSH on port 3502
    command: sh -c "yarn install && yarn dev"  # Keep the container running
    restart: on-failure

### Solution 2: Verify if `yarn dev` is Configured Properly

Ensure that `yarn dev` or the development command in your `package.json` is correctly configured to start a long-running server. Here's an example of what your `package.json` might look like:

{
  "name": "your-project",
  "scripts": {
    "dev": "webpack serve --mode development --open"  // Example for webpack dev server
  }
}

### Solution 3: Run the Container Interactively to Debug

If you want to debug why it is exiting, you can try running the container interactively. This will keep the container open so you can investigate manually.

docker-compose run --rm node sh

Once inside the container, run the following commands to verify the state:

yarn install   # Install dependencies
yarn dev       # Start the development server

### Step 1: Rebuild and Restart the Containers

After making the necessary changes to `docker-compose.yml` (e.g., adding the `command` to start the development server), make sure to rebuild the containers and restart them:

docker-compose down  # Stop and remove containers
docker-compose up --build -d  # Rebuild and start containers in detached mode

### Step 2: Monitor Logs

After restarting the containers, you can monitor the logs to ensure that the container is now running as expected:

docker-compose logs node

This should prevent the container from exiting immediately and allow it to stay running. Let me know if the issue persists!

### Here's how you can update your `docker-compose.yml`:

version: '3.3'

services:
  node:
    image: node:20-alpine
    container_name: oliver-node
    working_dir: /var/www/all4cloud-wordpress-website
    volumes:
      - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website
    ports:
      - "3502:22"  # Expose SSH on port 3502
    command: sh -c "yarn install && yarn dev"  # Run yarn install and start the dev server
    restart: always  # Ensure the container always restarts

### Explanation:
– **`restart: always`**: This will make sure that the container restarts automatically if it crashes or stops.
– **`command: sh -c "yarn install && yarn dev"`**: Keeps the container running by running the development server (`yarn dev`). If `yarn dev` is a long-running process, this will keep the container alive.

### Step 1: Rebuild and Restart the Containers

After updating the `docker-compose.yml` file, rebuild and restart the containers:

docker-compose down  # Stop and remove containers
docker-compose up --build -d  # Rebuild and start containers in detached mode

### Step 2: Verify Container Status

Check that the `oliver-node` container is running properly:

docker ps

This will show you a list of running containers. Look for the `oliver-node` container and ensure its status is `Up`.

### Step 3: Monitor Logs

Monitor the logs to ensure that everything is running smoothly:

docker-compose logs -f node

With `restart: always`, the container will keep restarting automatically if it exits or fails for any reason, ensuring that it is always running. Let me know if you encounter any further issues!

### To prevent the container from stopping and run `bash` interactively, use `docker-compose exec` instead of `docker-compose run`:

docker-compose exec node bash

### Difference:
– **`docker-compose run –rm node bash`**: This will start the container, run `bash`, and immediately remove the container after you exit the `bash` shell.
– **`docker-compose exec node bash`**: This allows you to execute commands inside the running container and keep the container running. You can enter the container interactively without removing it after exiting the shell.

### If You Still Want to Use `docker-compose run` and Keep It Running:
You can use `docker-compose run` with a long-running process like `tail -f` to keep the container alive. For example:

docker-compose run --rm node bash -c "yarn install && yarn dev && tail -f /dev/null"

This command will:
1. Run `yarn install` and `yarn dev`.
2. Keep the container running with `tail -f /dev/null`, which effectively blocks the container from exiting.

### Step 1: Rebuild and Restart the Containers

After making your adjustments, ensure that everything is running correctly by bringing the containers back up:

docker-compose up -d  # Start containers in detached mode

### Step 2: Verify the Node Container

Verify that the `oliver-node` container is running:

docker ps

The container should be listed, and it will stay running.

Let me know if you need more help!

### Step 1: Access the Container

Use the `docker exec` command to open a shell session in the `oliver-php` container:

docker exec -it oliver-php sh

This will open a shell (`sh`) inside the running `oliver-php` container.

### Step 2: Navigate to the Site 2 Directory

Once you're inside the container's shell, you can navigate to the directory you want (in this case, `site 2`). Assuming the `site 2` directory is inside the mounted volume (`/var/www/all4cloud-wordpress-website` or a similar path), you can use the `cd` command to go to it:

cd /var/www/all4cloud-wordpress-website/site2  # Adjust the path as needed

You can also list the directories to verify the path:

ls /var/www/all4cloud-wordpress-website  # To check if site2 is there

### Step 3: Work in the Site 2 Directory

Now that you're in the `site 2` directory, you can run any commands or make changes as needed.

### Notes:
– If you have multiple sites within the same container, make sure to specify the correct directory path.
– The volume `./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website` should have `site2` or the desired directory inside it if you're using that as your base.

### Option 1: Create Additional Databases Manually

You can manually create the second database by entering the MySQL container and using the MySQL client.

#### Step 1: Access the MySQL container

First, get into the MySQL container:

docker exec -it oliver-mysql bash

#### Step 2: Log into MySQL

Once inside the container, log into MySQL with the root password (or any user you've set up):

mysql -u root -p

When prompted, enter the password (`rootpassword` in your case, as per the `docker-compose.yml` file).

#### Step 3: Create the Second Database

Once you're inside the MySQL shell, you can create the second database:

CREATE DATABASE site_db2;

This will create a second database named `site_db2`. You can now proceed to create tables, users, etc., for the second database.

#### Step 4: Verify the Databases

You can verify the databases by running:

SHOW DATABASES;

This will list all the databases, including the newly created one (`site_db2`).

### Option 2: Modify the Docker Setup for Multiple Databases

If you want to automatically create multiple databases on container startup, you can create a custom initialization script and mount it as a volume in your `docker-compose.yml` file. Here’s how you can do it:

#### Step 1: Create an Initialization Script

Create a script that will create both databases when the MySQL container starts. For example, create a file named `init.sql` in a directory (e.g., `./mysql/init`).

-- init.sql
CREATE DATABASE IF NOT EXISTS site_db1;
CREATE DATABASE IF NOT EXISTS site_db2;

#### Step 2: Modify the `docker-compose.yml` to Use the Script

Update your `docker-compose.yml` file to mount the initialization script into the MySQL container. Make sure the path matches where you store the `init.sql` script.

services:
  olimysql:
    image: mysql:8.0
    container_name: oliver-mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site_db1  # You can keep one default database if needed
      MYSQL_USER: user
      MYSQL_PASSWORD: userpassword
    volumes:
      - ./mysql/data:/var/lib/mysql
      - ./mysql/init:/docker-entrypoint-initdb.d  # Mount the init script here
    ports:
      - "3306:3306"
    networks:
      - oliver-app-network
    restart: always

The `./mysql/init:/docker-entrypoint-initdb.d` volume mounts the `init.sql` script into the container's initialization directory. This directory is executed by MySQL when the container is first started.

#### Step 3: Rebuild and Restart the Container

Now, rebuild and restart the container to apply the changes:

docker-compose down
docker-compose up --build -d

This should automatically create both databases (`site_db1` and `site_db2`) when the container is started.

### Option 3: Create Multiple Databases with Different Users (Optional)

If you'd like each database to have its own user, you can modify the `init.sql` script to create users for each database:

-- init.sql
CREATE DATABASE IF NOT EXISTS site_db1;
CREATE DATABASE IF NOT EXISTS site_db2;

CREATE USER 'user1'@'%' IDENTIFIED BY 'password1';
CREATE USER 'user2'@'%' IDENTIFIED BY 'password2';

GRANT ALL PRIVILEGES ON site_db1.* TO 'user1'@'%';
GRANT ALL PRIVILEGES ON site_db2.* TO 'user2'@'%';

FLUSH PRIVILEGES;

This way, `user1` will have access to `site_db1`, and `user2` will have access to `site_db2`.

### Summary

– **Manually create databases** by logging into the MySQL container and running SQL commands.
– **Automatically create databases** during the container startup using a custom `init.sql` script and mounting it via Docker volumes.
– **Create different users for each database** (optional) by adjusting the `init.sql` script.

Let me know if this solves your issue or if you need further help!

### Step-by-Step Instructions:

1. **Create an `init.sql` Script**:
You can create an `init.sql` script that will be executed when the MySQL container is first initialized. In this script, you'll create multiple databases and grant a user access to all of them.

2. **Modify the `docker-compose.yml`**:
Ensure that the `MYSQL_USER` is correctly defined and that the initialization script is mounted into the MySQL container.

### Example:

#### Step 1: Create the `init.sql` Script

Create a directory (e.g., `./mysql/init`) and inside it, create an `init.sql` file with the following content:

-- init.sql

-- Create the databases
CREATE DATABASE IF NOT EXISTS site_db1;
CREATE DATABASE IF NOT EXISTS site_db2;

-- Grant the user privileges on both databases
GRANT ALL PRIVILEGES ON site_db1.* TO 'user'@'%';
GRANT ALL PRIVILEGES ON site_db2.* TO 'user'@'%';

-- Apply the changes
FLUSH PRIVILEGES;

This script will:
– Create `site_db1` and `site_db2` if they do not already exist.
– Grant the user `user` full privileges on both databases.
– Flush the privileges to apply the changes.

#### Step 2: Modify `docker-compose.yml`

Ensure your `docker-compose.yml` file mounts the `init.sql` script into the MySQL container, like so:

version: '3.3'

services:
  olimysql:
    image: mysql:8.0
    container_name: oliver-mysql
    environment:
      MYSQL_ROOT_PASSWORD: rootpassword
      MYSQL_DATABASE: site_db1  # Default database (optional)
      MYSQL_USER: user          # Define the user here
      MYSQL_PASSWORD: userpassword  # Define the password for 'user'
    volumes:
      - ./mysql/data:/var/lib/mysql
      - ./mysql/init:/docker-entrypoint-initdb.d  # Mount the init script here
    ports:
      - "3306:3306"
    networks:
      - oliver-app-network
    restart: always

– **`MYSQL_USER`**: Specifies the MySQL user (e.g., `user`) that will have access to the databases.
– **`MYSQL_PASSWORD`**: Specifies the password for the user.
– **`MYSQL_DATABASE`**: This is the default database that will be created for the user. The `init.sql` script will create additional databases.
– **Volume Mount**: The `./mysql/init:/docker-entrypoint-initdb.d` mounts the `init.sql` script into the container. MySQL will automatically execute this script when the container starts.

#### Step 3: Rebuild and Restart the Containers

After modifying the files, rebuild and restart your Docker containers:

docker-compose down  # Stop and remove containers
docker-compose up --build -d  # Rebuild and start containers in detached mode

### Step 4: Verify the Databases and User Privileges

Once the container is up, you can log into MySQL and verify that the databases and user privileges are set up correctly.

1. **Access the MySQL Container**:

docker exec -it oliver-mysql bash

2. **Log into MySQL**:

mysql -u root -p

Enter the root password (`rootpassword`) when prompted.

3. **Verify the Databases**:

SHOW DATABASES;

You should see `site_db1`, `site_db2`, and any other databases.

4. **Verify the User's Privileges**:

SHOW GRANTS FOR 'user'@'%';

This will show you what privileges the `user` has. You should see that they have all privileges on `site_db1` and `site_db2`.

### Conclusion

– **Manually create multiple databases** and assign privileges to the `MYSQL_USER` in the `init.sql` script.
– Ensure that the `docker-compose.yml` file mounts the script properly into the MySQL container.
– **Rebuild and restart** the container to apply the changes.

This method should allow you to have one user (`user`) with access to multiple databases (`site_db1`, `site_db2`, etc.). Let me know if you need further assistance!

### Step-by-Step Instructions

#### Step 1: Access the MySQL Container

You can access the MySQL container through SSH using Docker:

1. First, get into the MySQL container with `docker exec`:

docker exec -it oliver-mysql bash

This command will give you a bash shell inside the `oliver-mysql` container.

#### Step 2: Log into MySQL

Once inside the container, use the MySQL client to log in as the root user (or any other MySQL user with appropriate privileges).

mysql -u root -p

When prompted, enter the root password that you've set (e.g., `rootpassword`).

#### Step 3: Create Multiple Databases

Once logged into MySQL, create the additional databases as needed. For example, to create `site_db1` and `site_db2`, run the following SQL commands:

CREATE DATABASE IF NOT EXISTS site_db1;
CREATE DATABASE IF NOT EXISTS site_db2;

#### Step 4: Grant User Privileges on Databases

To grant the `MYSQL_USER` (e.g., `user`) access to both databases (`site_db1` and `site_db2`), use the following commands:

GRANT ALL PRIVILEGES ON site_db1.* TO 'user'@'%';
GRANT ALL PRIVILEGES ON site_db2.* TO 'user'@'%';

This grants full privileges to `user` for both databases.

#### Step 5: Flush Privileges

After granting the privileges, run the `FLUSH PRIVILEGES` command to apply the changes:

FLUSH PRIVILEGES;

#### Step 6: Verify the Databases and Privileges

You can verify that the databases have been created and the user has the necessary privileges.

1. **Check Databases**:

SHOW DATABASES;

You should see `site_db1` and `site_db2` in the list of databases.

2. **Check User Privileges**:

SHOW GRANTS FOR 'user'@'%';

This will show you the privileges assigned to `user`. You should see that `user` has `ALL PRIVILEGES` on both `site_db1` and `site_db2`.

#### Step 7: Exit MySQL and the Container

Once you've finished, exit MySQL and the container:

exit  # Exit MySQL
exit  # Exit the container

### Summary of Commands

Here’s a quick summary of the key commands to run inside the MySQL container:

docker exec -it oliver-mysql bash  # Enter the container
mysql -u root -p                   # Log into MySQL
CREATE DATABASE IF NOT EXISTS site_db1;
CREATE DATABASE IF NOT EXISTS site_db2;
GRANT ALL PRIVILEGES ON site_db1.* TO 'user'@'%';
GRANT ALL PRIVILEGES ON site_db2.* TO 'user'@'%';
FLUSH PRIVILEGES;
SHOW DATABASES;  # Verify the databases
SHOW GRANTS FOR 'user'@'%';  # Verify user privileges
exit  # Exit MySQL and the container

### Troubleshooting

– If you get any error like "Access Denied", ensure you're logged in with a user that has sufficient privileges to create databases and grant privileges.
– Make sure you’ve set the correct passwords and MySQL user configurations in your `docker-compose.yml` file.

### Method 1: Importing via MySQL Container's Shell

#### Step 1: Copy the `.sql` File to the Container (Optional)

If your `.sql` file is on your host machine, you can copy it into the MySQL container using the `docker cp` command.

docker cp /path/to/your-file.sql oliver-mysql:/your-file.sql

#### Step 2: Access the MySQL Container

docker exec -it oliver-mysql bash

#### Step 3: Log into MySQL

mysql -u root -p

You will be prompted to enter the root password (e.g., `rootpassword`).

#### Step 4: Select the Database

Before importing, make sure you select the database where you want to import your table:

USE your_database;

#### Step 5: Import the `.sql` File

Now, run the following command to import the `.sql` file:

SOURCE /your-file.sql;

#### Step 6: Exit MySQL and the Container

exit  # Exit MySQL
exit  # Exit the container

### Method 2: Using `docker exec` with `mysql` Command

If you prefer a one-liner approach from your host machine, you can directly run:

docker exec -i oliver-mysql mysql -u root -p'your_root_password' your_database < /path/to/your-file.sql

– Replace `your_database` with the name of your database.
– Replace `/path/to/your-file.sql` with the full path to your SQL file.
– Make sure to not have a space between `-p` and your password.

### Method 3: Using Volume Mount (if `.sql` file is already in a volume)

If you've mounted a directory in your Docker setup, you can access it directly. For example:

1. **Place the SQL file inside the mounted volume** (e.g., `./mysql/init`).

2. **Run the Import Command**:

docker exec -i oliver-mysql mysql -u root -p'your_root_password' your_database < /path/to/volume/your-file.sql

### Method 4: Using MySQL Client on Your Host Machine

If you have MySQL installed on your host machine and the MySQL container is exposing port `3306`, you can do:

mysql -h 127.0.0.1 -P 3306 -u root -p your_database < /path/to/your-file.sql

– `-h 127.0.0.1`: Connect to localhost.
– `-P 3306`: Use the port exposed by the MySQL container.

### Verifying the Import

After importing, you can verify the imported tables:

1. **Log back into MySQL**:

docker exec -it oliver-mysql mysql -u root -p

2. **Check Tables**:

USE your_database;
SHOW TABLES;

You should see the list of tables that were imported.

Let me know if you run into any issues!

bash: /var/www/wordpress-website-az-rosemeier/usr_p678156_1.sql: No such file or directory

indicates that the specified path to the `.sql` file is not found inside the MySQL container.

### Potential Causes and Solutions

1. **Ensure the Path is Correct on Your Host Machine**

The file path you are using (`/var/www/wordpress-website-az-rosemeier/usr_p678156_1.sql`) is referencing a path inside the MySQL container, but it needs to be accessible from the host system.

2. **Use the Correct Path on the Host System**

Make sure the `.sql` file is located on your host machine at the path you specified. If it's in a different directory, adjust the path accordingly.

For example:

docker exec -i oliver-mysql mysql -u root -p'rootpassword' rosemier < /path/to/your/usr_p678156_1.sql

Here, replace `/path/to/your/usr_p678156_1.sql` with the actual path on your host system.

3. **Mount the Volume Correctly in `docker-compose.yml`**

If the `.sql` file is inside a directory that is shared with the Docker container, ensure that this directory is correctly mounted in your `docker-compose.yml` file:

volumes:
     - ./wordpress-website-az-rosemeier:/var/www/wordpress-website-az-rosemeier

Then, inside the container, the path `/var/www/wordpress-website-az-rosemeier/usr_p678156_1.sql` should be accessible.

4. **Copy the SQL File into the Container**

If you’re not using volumes or the file is not accessible, you can copy the `.sql` file directly into the MySQL container:

docker cp /path/to/usr_p678156_1.sql oliver-mysql:/usr_p678156_1.sql

Then, run the import command using the new path:

docker exec -i oliver-mysql mysql -u root -p'rootpassword' rosemier < /usr_p678156_1.sql

5. **Verify the File Exists Inside the Container**

You can enter the MySQL container to verify that the file exists:

docker exec -it oliver-mysql bash

Once inside, check if the file is there:

ls /var/www/wordpress-website-az-rosemeier

If the file is not there, you need to ensure it's correctly copied or mounted.

### Summary

Make sure:
– The path to the `.sql` file is correct on your host machine.
– The file is accessible inside the container if you are using volume mounts.
– If needed, copy the file directly into the container using `docker cp`.

Adjust your import command based on where the file is actually located.

### Step-by-Step Instructions

1. **Edit the Dockerfile for PHP**

First, make sure you're modifying the correct Dockerfile that is used for building the PHP container. Here's an example of how you could add Node.js installation to your `Dockerfile`.

**Dockerfile Example:**

# Use the official PHP image as the base image
   FROM php:8.0-fpm

   # Install system dependencies for Node.js and Yarn
   RUN apt-get update && apt-get install -y 
       curl 
       gnupg2 
       ca-certificates 
       lsb-release 
       apt-transport-https

   # Add NodeSource repository for Node.js (LTS version)
   RUN curl -fsSL https://deb.nodesource.com/setup_20.x | bash -

   # Install Node.js and Yarn
   RUN apt-get install -y nodejs 
       && curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - 
       && echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list 
       && apt-get update && apt-get install -y yarn

   # Clean up apt caches to reduce image size
   RUN apt-get clean && rm -rf /var/lib/apt/lists/*
   
   # Install PHP extensions (if required)
   RUN docker-php-ext-install pdo pdo_mysql

This will:
– Install Node.js (v20 in this example) and Yarn inside the PHP container.
– You can modify the Node.js version if needed (e.g., replace `20.x` with the version you need).
– It also ensures you install the necessary dependencies to support Yarn installation.

2. **Rebuild the PHP Container**

After modifying the Dockerfile, rebuild the PHP container:

docker-compose build php

This will trigger the rebuild of the PHP container and install Node.js and Yarn along with any other dependencies.

3. **Verify the Installation**

Once the container is up, you can verify that Node.js and Yarn have been successfully installed by accessing the PHP container and running:

docker exec -it oliver-php bash

Then check the versions of Node.js and Yarn:

node -v
   yarn -v

You should see the installed versions of Node.js and Yarn printed out.

4. **Use Node.js and Yarn in the PHP Container**

Now that Node.js and Yarn are installed, you can use them inside the PHP container. For example, you can run commands like `yarn install` or `npm install` directly in the container.

### Docker Compose Update (Optional)

If you want to ensure Node.js and Yarn are always installed and available in the PHP container, you can ensure the `php` service in your `docker-compose.yml` points to the correct Dockerfile.

php:
  build:
    context: ./php  # Make sure this points to the directory with your Dockerfile
  container_name: oliver-php
  volumes:
    - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website
  expose:
    - "9000"
  working_dir: /var/www/all4cloud-wordpress-website
  networks:
    - oliver-app-network
  restart: on-failure

### Summary

– **Install Node.js**: Add installation commands for Node.js and Yarn in your Dockerfile.
– **Rebuild the container**: Rebuild the PHP container using `docker-compose build`.
– **Verify installation**: Check if Node.js and Yarn are installed inside the container by running `node -v` and `yarn -v`.

This setup will allow you to use Node.js and Yarn inside your PHP container. Let me know if you need further help!

docker inspect oliver-node

This command will return a detailed JSON output with information about the container, such as:

– Container configuration (e.g., image, environment variables)
– Volumes mounted inside the container
– Network settings
– Logs
– Resource limits
– Status of the container
– Port mappings
– And much more.

If you want a more readable or specific piece of information, you can use the `–format` flag to filter the results. For example:

### To get the container's IP address:

docker inspect --format '{{.NetworkSettings.IPAddress}}' oliver-node

### To see the port mappings:

docker inspect --format '{{json .NetworkSettings.Ports}}' oliver-node

You can also use `jq` to parse the output if you're looking for more specific information or need to process the JSON output:

docker inspect oliver-node | jq '.[0].NetworkSettings.Ports'

This will give you more control over the output and make it easier to read or extract the data you need. Let me know if you'd like further assistance with interpreting the output!

# Install system dependencies
RUN apt-get update && apt-get install -y
zip
unzip
git
curl
libpng-dev
libjpeg-dev
libfreetype6-dev
libzip-dev
&& docker-php-ext-install pdo pdo_mysql zip gd mysqli

# Copy Composer
COPY –from=composer:2.7 /usr/bin/composer /usr/bin/composer

# Copy custom php.ini
COPY php.ini /usr/local/etc/php/php.ini

WORKDIR /var/www

### Explanation of the Dockerfile

1. **Base Image (PHP 8.2 FPM)**:
– `FROM php:8.2-fpm`: You're using the official PHP 8.2 image with FPM (FastCGI Process Manager) as the base image, which is perfect for serving PHP-based applications.

2. **Install Dependencies**:
– You're installing essential system dependencies (`zip`, `unzip`, `git`, `curl`, etc.), followed by the installation of PHP extensions (`pdo`, `pdo_mysql`, `zip`, `gd`, `mysqli`). This will ensure your PHP container is set up with these commonly used extensions.

RUN apt-get update && apt-get install -y 
       zip 
       unzip 
       git 
       curl 
       libpng-dev 
       libjpeg-dev 
       libfreetype6-dev 
       libzip-dev 
       && docker-php-ext-install pdo pdo_mysql zip gd mysqli

3. **Copy Composer**:
– The `COPY –from=composer:2.7 /usr/bin/composer /usr/bin/composer` command copies Composer into your container from the official Composer image. This ensures you can run `composer` commands in your PHP container.

4. **Copy Custom `php.ini`**:
– `COPY php.ini /usr/local/etc/php/php.ini` will copy your custom `php.ini` file from your local machine into the container, allowing you to customize PHP settings (e.g., memory limits, upload limits, etc.).

5. **Set Working Directory**:
– `WORKDIR /var/www`: This sets the working directory inside the container where your PHP files will be located. It’s a common practice to place the website files here.

### Possible Improvements or Considerations

1. **Optimize Layer Caching**:
It's a good practice to minimize the number of layers in your Dockerfile. You could combine the `apt-get update` and `apt-get install` into one `RUN` command to improve layer caching and reduce the number of layers. For example:

RUN apt-get update && apt-get install -y 
       zip 
       unzip 
       git 
       curl 
       libpng-dev 
       libjpeg-dev 
       libfreetype6-dev 
       libzip-dev && 
       docker-php-ext-install pdo pdo_mysql zip gd mysqli && 
       apt-get clean && rm -rf /var/lib/apt/lists/*

This way, you combine all the commands in one layer, clean up unnecessary package lists, and reduce the image size.

2. **Add Node.js (Optional)**:
If you're also planning to install Node.js or any front-end dependencies, you can install them within this container by adding the necessary commands to install Node.js, npm, or Yarn.

Here's an example of how to install Node.js:

# Install Node.js and npm
   RUN curl -fsSL https://deb.nodesource.com/setup_20.x | bash - && 
       apt-get install -y nodejs && 
       apt-get clean && rm -rf /var/lib/apt/lists/*

3. **Permissions for Composer**:
If you're running Composer commands as a non-root user, make sure that the proper file permissions are set for the directories where Composer installs packages. You may need to adjust the file permissions depending on your use case.

4. **Exposing Ports**:
If you plan to run the PHP-FPM service on a specific port (for example, `9000`), you should expose the port in your Dockerfile:

EXPOSE 9000

5. **Optional PHP Extensions**:
Depending on your application, you might need additional PHP extensions. For example, `intl`, `bcmath`, `soap`, etc. You can install these extensions in the same way by adding them to the `docker-php-ext-install` command.

### Final Dockerfile

Here's the final version of your Dockerfile, incorporating the improvements and best practices:

FROM php:8.2-fpm

# Install system dependencies and PHP extensions
RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev && 
    docker-php-ext-install pdo pdo_mysql zip gd mysqli && 
    apt-get clean && rm -rf /var/lib/apt/lists/*

# Install Node.js and npm (if required)
RUN curl -fsSL https://deb.nodesource.com/setup_20.x | bash - && 
    apt-get install -y nodejs && 
    apt-get clean && rm -rf /var/lib/apt/lists/*

# Copy Composer
COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

# Copy custom php.ini
COPY php.ini /usr/local/etc/php/php.ini

# Set the working directory
WORKDIR /var/www

# Expose PHP-FPM port
EXPOSE 9000

### Building the Container

After making these changes, you can build the PHP container by running:

docker-compose build php

This will build the container and install PHP, Composer, Node.js, and all necessary extensions.

Let me know if you need further adjustments or run into any issues!

The `–no-cache` option, on the other hand, is used with `docker build` to ensure that Docker does not use the cache from previous builds and starts the build from scratch, which is useful if you want to ensure that everything is rebuilt without using any previously cached layers.

### How to Use Both Together

If you want to rebuild your Docker containers from scratch without any cached layers and also clean up any orphaned containers (those no longer referenced by the `docker-compose.yml`), you would run the following:

1. **Rebuild containers without cache and remove orphaned containers**:

docker-compose up --build --no-cache --remove-orphans

This command does the following:
– `–build`: Forces Docker Compose to rebuild the images for the services defined in your `docker-compose.yml` file.
– `–no-cache`: Prevents Docker from using the build cache, so the build starts from scratch.
– `–remove-orphans`: Removes any containers that are no longer defined in the current `docker-compose.yml` configuration.

### Example Scenario

Let's say you've made changes to your `docker-compose.yml` file and you want to make sure that the old containers that were linked to previously defined services are cleaned up, and you also want to rebuild everything from scratch.

In this case, you would run the command:

docker-compose down && docker-compose up --build --no-cache --remove-orphans

– `docker-compose down`: Stops and removes all running containers, networks, and volumes related to your services.
– `docker-compose up –build –no-cache –remove-orphans`: Rebuilds the services and cleans up orphaned containers.

This ensures that you have a fresh environment with no leftover containers or caches from previous builds.

Let me know if you need further assistance!

### Step-by-Step Solution to Install Yarn in Your Docker Container

Here’s how you can modify your `Dockerfile` to install Yarn:

1. **Add Yarn installation to the Dockerfile**:

If you're using a Debian/Ubuntu-based image (like `php:8.2-fpm`), you can install Yarn from the official Yarn package repository.

Add the following lines to your `Dockerfile` after installing the necessary dependencies (and optionally Node.js if needed):

# Install Yarn
   RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && 
       echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && 
       apt-get update && 
       apt-get install -y yarn

This adds Yarn's package repository, updates the apt index, and installs Yarn.

2. **Rebuild the Docker container**:

After adding the Yarn installation steps to your Dockerfile, you need to rebuild your container to apply the changes:

docker-compose build php

3. **Check if Yarn is Installed**:

After rebuilding the container, you can verify if Yarn was installed correctly by running:

docker exec -it oliver-php yarn --version

This should output the installed version of Yarn, confirming that it's available in your container.

### Updated `Dockerfile` Example

Here’s how your `Dockerfile` might look after adding Yarn installation:

FROM php:8.2-fpm

# Install system dependencies and PHP extensions
RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev && 
    docker-php-ext-install pdo pdo_mysql zip gd mysqli && 
    apt-get clean && rm -rf /var/lib/apt/lists/*

# Install Node.js and npm
RUN curl -fsSL https://deb.nodesource.com/setup_20.x | bash - && 
    apt-get install -y nodejs && 
    apt-get clean && rm -rf /var/lib/apt/lists/*

# Install Yarn
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && 
    echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && 
    apt-get update && 
    apt-get install -y yarn

# Copy Composer
COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

# Copy custom php.ini
COPY php.ini /usr/local/etc/php/php.ini

# Set the working directory
WORKDIR /var/www

# Expose PHP-FPM port
EXPOSE 9000

### After Rebuilding the Container

Once you rebuild the container, you should be able to run `yarn` commands without encountering the `yarn not found` error.

Let me know if you run into any issues!

Presence of the "packageManager" field indicates that the project is meant to be used with Corepack, a tool included by default with all official Node.js distributions starting from 16.9 and 14.19.
Corepack must currently be enabled by running corepack enable in your terminal. For more information, check out https://yarnpkg.com/corepack.

Here's how to fix this issue:

### Solution 1: Enable Corepack (Recommended)

Corepack is a tool that comes with Node.js (starting from version `14.19.0` or `16.9.0`), and it helps manage package managers like Yarn and pnpm according to the versions specified in your project.

1. **Install Corepack** (if not already available):

First, you need to install and enable Corepack in your container:

Add this to your `Dockerfile` after installing Node.js:

# Enable Corepack
   RUN corepack enable

This will enable Corepack, which will automatically use the version of Yarn specified in your `package.json`.

2. **Rebuild the Docker container**:

After modifying the `Dockerfile`, rebuild your Docker container:

docker-compose build php

3. **Verify Yarn version**:

You can now check if Corepack is managing the correct version of Yarn:

docker exec -it oliver-php yarn --version

This should output the version specified in your `package.json` (`4.3.1`).

### Solution 2: Manually Install the Correct Version of Yarn

If you prefer not to use Corepack, you can manually install the required version of Yarn in your Docker container. Here's how:

1. **Modify your Dockerfile to install Yarn `4.3.1`**:

Add the following steps to install the correct version of Yarn:

# Install the specific version of Yarn (4.3.1)
   RUN curl -o- -L https://yarnpkg.com/install.sh | bash -s -- --version 4.3.1

This will download and install Yarn version `4.3.1` in your container.

2. **Rebuild the Docker container**:

After modifying the `Dockerfile`, rebuild the container:

docker-compose build php

3. **Verify the correct version of Yarn**:

Check if the correct version of Yarn is now installed:

docker exec -it oliver-php yarn --version

This should output `4.3.1`.

### Conclusion

The preferred method is to enable **Corepack**, as it automatically manages the package manager versions specified in your project. If you manually install the Yarn version, you should be sure that your project’s dependencies are aligned with the specified version.

# Expose PHP-FPM port
EXPOSE 9000

### Breakdown of Updates:

1. **Corepack Enablement**:
– The command `RUN corepack enable` enables Corepack, which ensures that the version of Yarn specified in your `package.json` file (e.g., `4.3.1`) will be used automatically without needing to manually install Yarn.

2. **Install Node.js and Dependencies**:
– The `curl -fsSL https://deb.nodesource.com/setup_20.x | bash -` command installs Node.js (version 20.x) on your container, which is required for using Yarn.

3. **Composer and PHP Extensions**:
– The `COPY –from=composer:2.7 /usr/bin/composer /usr/bin/composer` command copies the Composer binary from the official Composer image into the PHP container.
– PHP extensions are installed for MySQL, GD, and other dependencies required for your project.

### Steps to Apply:

1. **Rebuild Your Docker Container**:

After updating the `Dockerfile`, rebuild your container by running:

docker-compose build php

2. **Verify the Yarn Version**:

Once the container is rebuilt, you can verify that Yarn is correctly set up by checking its version:

docker exec -it oliver-php yarn --version

This should print the version of Yarn specified in your `package.json`, such as `4.3.1`.

FROM php:8.2-fpm

# Install system dependencies and PHP extensions
RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev && 
    docker-php-ext-install pdo pdo_mysql zip gd mysqli && 
    apt-get clean && rm -rf /var/lib/apt/lists/*

# Install Node.js
RUN curl -fsSL https://deb.nodesource.com/setup_20.x | bash - && 
    apt-get install -y nodejs && 
    apt-get clean && rm -rf /var/lib/apt/lists/*

# Install Yarn 4.3.1
RUN corepack prepare yarn@4.3.1 --activate

# Copy Composer
COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

# Copy custom php.ini
COPY php.ini /usr/local/etc/php/php.ini

# Set the working directory
WORKDIR /var/www

# Expose PHP-FPM port
EXPOSE 9000

### Key Changes:

1. **Installing Node.js**:
– Node.js is installed via the official NodeSource repository (version 20.x). You can adjust this if you need a different version.

2. **Install Yarn 4.3.1**:
– The command `RUN corepack prepare yarn@4.3.1 –activate` explicitly installs Yarn version `4.3.1` and activates it in your container.

3. **Other Enhancements**:
– Composer is copied into the container from the official Composer image.
– PHP extensions (`pdo`, `pdo_mysql`, `zip`, `gd`, `mysqli`) are installed for your PHP setup.

### Steps to Apply:

1. **Rebuild the Docker Image**:

After updating your `Dockerfile`, rebuild your Docker container:

docker-compose build php

2. **Verify Yarn Version**:

Once the container is rebuilt, you can check that Yarn `4.3.1` is installed by running:

docker exec -it oliver-php yarn --version

This should display:

4.3.1

Now, you should have **Yarn 4.3.1** installed in your PHP container, and the project should use the correct version of Yarn as specified in the `package.json`.

Let me know if you need further adjustments!

### Updated `Dockerfile` to Ensure Yarn 4.3.1 is Available

We’ll modify the Dockerfile to explicitly install **Yarn 4.3.1** and ensure that it's available in the container’s PATH. This will involve using **Corepack** to install the correct version of Yarn.

Here’s an updated Dockerfile:

FROM php:8.2-fpm

# Install system dependencies and PHP extensions
RUN apt-get update && apt-get install -y 
    zip 
    unzip 
    git 
    curl 
    libpng-dev 
    libjpeg-dev 
    libfreetype6-dev 
    libzip-dev 
    && docker-php-ext-install pdo pdo_mysql zip gd mysqli 
    && apt-get clean && rm -rf /var/lib/apt/lists/*

# Install Node.js (version 20.x)
RUN curl -fsSL https://deb.nodesource.com/setup_20.x | bash - && 
    apt-get install -y nodejs && 
    apt-get clean && rm -rf /var/lib/apt/lists/*

# Install Yarn 4.3.1 using Corepack
RUN corepack enable && corepack prepare yarn@4.3.1 --activate

# Verify Yarn installation
RUN yarn --version

# Copy Composer (from official Composer image)
COPY --from=composer:2.7 /usr/bin/composer /usr/bin/composer

# Copy custom php.ini
COPY php.ini /usr/local/etc/php/php.ini

# Set the working directory
WORKDIR /var/www

# Expose PHP-FPM port
EXPOSE 9000

### Key Changes:

1. **Install Yarn using Corepack**:
– `RUN corepack enable && corepack prepare yarn@4.3.1 –activate` ensures that **Yarn 4.3.1** is installed using Corepack, which manages the version specified in your `package.json` file.

2. **Verify Yarn Version**:
– `RUN yarn –version` will check if Yarn is installed correctly. If it’s not, this will show an error during the build process, helping us diagnose the issue.

3. **Install Node.js**:
– Node.js is installed from the official NodeSource repository (version 20.x), which is required for running Yarn.

### Steps to Apply:

1. **Rebuild the Docker Image**:

After updating the Dockerfile, rebuild your Docker container by running:

docker-compose build php

2. **Verify Yarn Installation**:

Once the container is rebuilt, check if Yarn 4.3.1 is available by running the following command inside the running container:

docker exec -it oliver-php yarn --version

This should output `4.3.1`. If you still encounter issues, we can debug further by checking the installation paths or other environment variables.

Here’s how you can grant the `www-data` user appropriate permissions for the `uploads` folder.

### 1. **Create and Set Permissions for the Uploads Folder**

Let’s assume your uploads directory is located at `/var/www/uploads`. We need to ensure that:

– The `www-data` user has read/write permissions to this folder.
– The folder is created if it doesn’t already exist.

You can achieve this by adding the following commands to your Dockerfile.

### Dockerfile Update:

# Create the uploads folder and set ownership to www-data
RUN mkdir -p /var/www/uploads && 
    chown -R www-data:www-data /var/www/uploads && 
    chmod -R 755 /var/www/uploads

### Explanation:

– `mkdir -p /var/www/uploads`: Creates the `uploads` folder if it doesn't exist.
– `chown -R www-data:www-data /var/www/uploads`: Recursively changes the ownership of the folder and its contents to the `www-data` user and group (which is the default user for PHP and Nginx in Docker).
– `chmod -R 755 /var/www/uploads`: Sets the folder's permissions to allow the owner (`www-data`) to read, write, and execute, while others can only read and execute.

### 2. **Ensure Correct Permissions for All Files/Directories**

If the `uploads` directory is mapped to a volume (for example, from the host), you may need to set the permissions outside of Docker, especially if the files already exist. For this, you can run the following commands after starting the container:

1. **Start the Docker container:**

docker-compose up -d

2. **Grant permissions from inside the container:**

Run the following command inside the PHP container to adjust permissions:

docker exec -it oliver-php bash
   chown -R www-data:www-data /var/www/uploads
   chmod -R 755 /var/www/uploads

3. **Test File Uploads:**

Once the container is running with the correct permissions, test uploading files to the `uploads` folder to ensure that the `www-data` user has sufficient permissions.

### 3. **Ensure Nginx and PHP-FPM are Configured to Use the Correct User**

If needed, make sure your Nginx and PHP-FPM configurations are using the `www-data` user. The default Docker images for both Nginx and PHP-FPM use the `www-data` user, but you may need to check your Nginx config files (`nginx.conf`) for user directives.

### Example Nginx Config (`nginx.conf`):

Make sure your Nginx config includes the following line to use the `www-data` user:

user www-data;

### Conclusion

Once you’ve added these changes, the `www-data` user should have full access to the `uploads` folder, enabling file uploads. Let me know if this works for you, or if you encounter any further issues!
