Add Adminer to Docker

If you plan to add it to Docker later or in another environment, let me know so I can provide guidance on adding it to a Docker container.

Here's an example `docker-compose.yml`:

version: '3.8'

services:
  db:
    image: mysql:8.0
    container_name: mysql_db
    environment:
      MYSQL_ROOT_PASSWORD: root_password
      MYSQL_DATABASE: my_database
      MYSQL_USER: user
      MYSQL_PASSWORD: user_password
    volumes:
      - db_data:/var/lib/mysql
    ports:
      - "3306:3306"

  adminer:
    image: adminer:latest
    container_name: adminer
    ports:
      - "8080:8080"
    depends_on:
      - db

volumes:
  db_data:

### Explanation of the Setup

– **Database Service (`db`)**:
– Uses the official MySQL image.
– Sets environment variables for MySQL root password, database name, username, and user password.
– Exposes MySQL on port `3306` (you can change this if needed).

– **Adminer Service (`adminer`)**:
– Uses the Adminer image.
– Exposes Adminer on port `8080` (so you can access it at `http://localhost:8080`).

### Usage

1. Save this file as `docker-compose.yml`.
2. Run the services with:

docker-compose up -d

3. You can then access Adminer in your browser at `http://localhost:8080`.

Let me know if you have any custom configurations or additional requirements!

Here's an example `docker-compose.yml`:

version: '3.8'

services:
  db:
    image: mysql:8.0
    container_name: mysql_db
    environment:
      MYSQL_ROOT_PASSWORD: root_password
      MYSQL_DATABASE: my_database
      MYSQL_USER: user
      MYSQL_PASSWORD: user_password
    volumes:
      - db_data:/var/lib/mysql
    ports:
      - "3306:3306"

  phpmyadmin:
    image: phpmyadmin/phpmyadmin:latest
    container_name: phpmyadmin
    environment:
      PMA_HOST: db
      PMA_USER: user
      PMA_PASSWORD: user_password
      PMA_PORT: 3306
    ports:
      - "8080:80"
    depends_on:
      - db

volumes:
  db_data:

### Explanation of the Setup

– **Database Service (`db`)**:
– Uses the official MySQL image.
– Sets environment variables for MySQL root password, database name, username, and user password.
– Exposes MySQL on port `3306`.

– **phpMyAdmin Service (`phpmyadmin`)**:
– Uses the phpMyAdmin image.
– Configures phpMyAdmin to connect to the `db` service with the specified MySQL user credentials.
– Exposes phpMyAdmin on port `8080`, so you can access it at `http://localhost:8080`.

### Usage

1. Save this file as `docker-compose.yml`.
2. Run the services with:

docker-compose up -d

3. You can then access phpMyAdmin in your browser at `http://localhost:8080`.
