### Step 1: Stop and Remove All Containers, Networks, and Volumes

1. **Stop all running containers:**

docker-compose down --volumes --remove-orphans

2. **Remove all existing Docker containers, images, networks, and volumes (Warning: This will remove all Docker resources):**

docker system prune -a --volumes

> Note: Be cautious with this command as it deletes everything Docker-related on your system.

### Step 2: Rebuild and Start Your Docker Containers

1. **Rebuild all the images (use `–no-cache` to ensure a fresh build):**

docker-compose build --no-cache

2. **Start the services:**

docker-compose up -d

### Step 3: Verify Everything is Running

– **List all running containers:**

docker ps

– **Check logs if needed:**

docker-compose logs -f

### Explanation

– `docker-compose down –volumes –remove-orphans` stops and removes containers, networks, and named volumes created by `docker-compose`.
– `docker system prune -a –volumes` removes **all** unused Docker data including containers, networks, images, and volumes.
– `docker-compose build –no-cache` rebuilds your Docker images without using any cached layers to ensure everything is fresh.

These steps will give you a clean slate for your Docker environment based on your `docker-compose.yml` file.

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;
}

### 1. Check Nginx Configuration File

Your Nginx configuration looks mostly good, but a couple of things might need adjustment. Here are some things to consider:

#### **1.1. Document Root Path**

Make sure the path to your WordPress site in Nginx's `root` directive is correct. You're using:

root /var/www/all4cloud-wordpress-website/web;

Ensure that the path `/var/www/all4cloud-wordpress-website/web` inside your container actually contains the WordPress site. If your WordPress site is inside `./applications/all4cloud-wordpress-website` (based on your `docker-compose.yml`), check if the directory structure matches.

If the root directory is incorrect, update it to the correct path in the container:

root /var/www/all4cloud-wordpress-website;

#### **1.2. File Permissions**

Make sure that the WordPress files in `/var/www/all4cloud-wordpress-website` have the correct permissions for Nginx to read them. Inside the `nginx` container, try the following command to check the files:

ls -l /var/www/all4cloud-wordpress-website

Ensure the correct permissions and ownership for the files. If necessary, run:

chown -R www-data:www-data /var/www/all4cloud-wordpress-website

#### **1.3. PHP-FPM Configuration**

Check that PHP-FPM is correctly handling requests. You're already proxying PHP requests to `php:9000`:

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

Make sure the `php` container is up and running and that it listens on port `9000`.

### 2. Verify Docker Container Setup

#### **2.1. Check if Containers Are Running**

Make sure all relevant containers are running, especially `nginx`, `php`, and `mysql`:

docker ps

If any of the containers (especially `php` or `nginx`) are not running, check the logs for error messages:

docker-compose logs nginx
docker-compose logs php

#### **2.2. Check Network Connectivity**

Make sure that `nginx` can communicate with the `php` container on port `9000`. They should both be on the same Docker network, as specified in your `docker-compose.yml` file:

networks:
  oliver-app-network:
    driver: bridge

Check the network connectivity between `nginx` and `php`:

docker exec -it oliver-nginx ping php

If `php` doesn't respond, it means there might be a network issue.

### 3. Check Docker Volumes

Ensure that the volumes are mounted correctly and that the files in `./applications/all4cloud-wordpress-website` on your host are properly available inside the container. Verify with:

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

### 4. Verify Port and URL

Ensure that the Nginx service is correctly exposed to port `3500` and that no other service is interfering with the port.

Check if the port is open and accessible:

netstat -tuln | grep 3500

### 5. Check for Errors in Logs

Finally, check the Nginx and PHP-FPM logs for any errors. For Nginx:

docker exec -it oliver-nginx cat /var/log/nginx/site1_error.log

For PHP-FPM logs:

docker exec -it oliver-php cat /var/log/php7.4-fpm.log

### Summary of Things to Check:
1. Nginx document root path should match the actual path inside the container.
2. Ensure proper file permissions and ownership for the WordPress directory.
3. Check PHP-FPM is running and reachable from Nginx.
4. Verify container and network connectivity.
5. Check for port conflicts and open ports.
6. Review logs for errors.

If any of these checks turn up an issue, we can troubleshoot further based on that.

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

### 1. **Check Container Logs**

First, you need to check the logs of the container that isn't running (in this case, it looks like the container ID `fac5fa633299c054624232b49fe016d29f4c29a67ce7afd43059af3f98c656e4` isn't running).

To check the logs of the container:

docker logs fac5fa633299c054624232b49fe016d29f4c29a67ce7afd43059af3f98c656e4

Look for error messages or reasons why the container stopped. Common issues could include configuration errors, missing files, or dependency issues.

### 2. **Restart the Container**

If you see that the container failed due to a temporary issue, try restarting it:

docker start fac5fa633299c054624232b49fe016d29f4c29a67ce7afd43059af3f98c656e4

### 3. **Rebuild and Restart All Containers**

If the container fails to start due to build or configuration issues, rebuild your entire Docker setup:

docker-compose down --volumes --remove-orphans
docker-compose build --no-cache
docker-compose up -d

This will ensure all containers are rebuilt from scratch and restarted.

### 4. **Check Docker Compose Logs**

You can also check the logs for all containers managed by `docker-compose` to look for issues:

docker-compose logs -f

This command will show you logs from all containers, including any error messages that might explain why a container isn't running.

### 5. **Check for Configuration Errors**

If the container is still failing to start, check your `docker-compose.yml` configuration file for any errors or misconfigurations, particularly in the `build` section, ports, volumes, and dependencies.

### 6. **Resource Availability**

Sometimes, containers fail to start due to resource constraints, such as insufficient memory or CPU. Check if your system is running out of resources by using:

docker stats

This will show resource usage for all running containers.

### 7. **Check the Docker Daemon**

Sometimes the Docker daemon itself can have issues. Restarting the Docker service might help:
– On Windows:
1. Open the Docker Desktop application and click on the settings icon.
2. Restart Docker from the Docker Desktop UI.

– On Linux:

sudo systemctl restart docker

Once Docker is restarted, try starting the containers again.

### Summary of Next Steps:
– Check logs for the specific container (`docker logs `).
– Restart the container if it's a temporary issue (`docker start `).
– Rebuild and restart all containers (`docker-compose down`, `docker-compose build –no-cache`, `docker-compose up -d`).
– Check Docker Compose logs for errors (`docker-compose logs -f`).
– Ensure there are no resource issues (`docker stats`).
– Restart the Docker service if needed.

Let me know what the logs say or if the issue persists, and we can narrow it down further.

### Steps to Troubleshoot the `oliver-nginx` Container

#### 1. **Check Nginx Container Logs**

To understand why the `oliver-nginx` container failed, you can view the logs:

docker logs oliver-nginx

Look for error messages in the logs that can give you more details about the problem.

#### 2. **Inspect the Nginx Configuration**

There may be an issue with your Nginx configuration. Since you're using the custom configuration file `all4cloud-wordpress-website.conf`, check the following:

– Ensure the syntax in the configuration file is correct.
– Make sure the file is being mounted properly into the container.

To inspect the configuration, try the following:

– Check for syntax errors in the configuration file:

docker exec -it oliver-nginx nginx -t

This will test the Nginx configuration and report any issues.

#### 3. **Ensure Nginx Can Access the Web Directory**

Make sure the `root` directory `/var/www/all4cloud-wordpress-website/web` exists and contains the appropriate files inside the container. To check this, run:

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

If it doesn't exist, verify the volume mount in your `docker-compose.yml` to make sure it points to the correct location on your host machine.

The volume definition:

volumes:
  - ./applications/all4cloud-wordpress-website:/var/www/all4cloud-wordpress-website

Ensure that `./applications/all4cloud-wordpress-website` on the host contains the correct files and directory structure.

#### 4. **Permissions Issue**

Nginx needs the proper permissions to read files. Make sure the WordPress directory and files inside the container are accessible by the Nginx user (`www-data` in most cases). You can set the correct permissions by running:

docker exec -it oliver-nginx chown -R www-data:www-data /var/www/all4cloud-wordpress-website

#### 5. **Container Restart**

After checking the configuration and fixing any issues, restart the container:

docker-compose restart oliver-nginx

If you continue to encounter issues, the logs will give more specific error messages that will help pinpoint the exact problem. Let me know what the logs say or if there are any specific errors that you need help with!
