WordPress with MySQL and PHP MyAdmin

This example defines one of the basic setups for WordPress. More details on how this works can be found on the official WordPress image page.

    # If you really want to use MySQL, uncomment the following line
    #image: mysql:8.0.27

    volumes:
      # Use the following line if you want to use the default wp-content directory
      # - ./wp-content:/var/www/html/wp-content
      # Use the following line if you want to use a custom wp-content directory

When deploying this setup, docker compose maps the WordPress container port 80 to port 80 of the host as specified in the compose file.

ℹ️ INFO For compatibility purpose between AMD64 and ARM64 architecture, we use a MariaDB as database instead of MySQL. You still can use the MySQL image by uncommenting the following line in the Compose file #image: mysql:8.0.27

Deploy with docker compose

$ docker compose up -d
Creating network "wordpress-mysql_default" with the default driver
Creating volume "wordpress-mysql_db_data" with default driver
...
Creating wordpress-mysql_db_1        ... done
Creating wordpress-mysql_wordpress_1 ... done

Expected result

Check containers are running and the port mapping:

$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                 NAMES
5fbb4181a069        wordpress:latest    "docker-entrypoint.s…"   35 seconds ago      Up 34 seconds       0.0.0.0:80->80/tcp    wordpress-mysql_wordpress_1
e0884a8d444d        mysql:8.0.19        "docker-entrypoint.s…"   35 seconds ago      Up 34 seconds       3306/tcp, 33060/tcp   wordpress-mysql_db_1

Navigate to http://localhost:80 in your web browser to access WordPress.

Stop and remove the containers

docker compose down

To remove all WordPress data, delete the named volumes by passing the -v parameter:

docker compose down -v
