Docker Compose for WP and PHPMyAdmin

Thank you thank you thank you! That was the missing piece I needed as well…

PMA_HOST: wordpress_db

Really useful! +100 Thanks :)

I just logged in to say thank you for this bit:

PMA_HOST: wordpress_db

:)

It’s working now. I had to had the env variable PMA_HOST: wordpress_db.

So my final .yml file look like this.

version: '2'
services:
  wordpress:
    image: wordpress:latest
    networks:
      - front
      - back
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_PASSWORD: examplepass
      WORDPRESS_DB_NAME: wpdb
      WORDPRESS_TABLE_PREFIX: wp_
      WORDPRESS_DB_HOST: wordpress_db
    volumes:
      - ./wordpress-data:/var/www/html
      - ./php/uploads.ini:/usr/local/etc/php/conf.d/uploads.ini
  wordpress_db:
    image: mariadb:latest
    environment:
      MYSQL_ROOT_PASSWORD: examplepass
    volumes:
      - wordpress-db-data:/var/lib/mysql
    networks:
      - back
  phpmyadmin:
    image: phpmyadmin/phpmyadmin:latest
    networks:
      - back
    ports:
      - 8181:80
    environment:
      MYSQL_USERNAME: root
      MYSQL_ROOT_PASSWORD: examplepass
      PMA_HOST: wordpress_db
volumes:
    wordpress-db-data:
      driver: local
networks:
  front:
  back:

Hi,

Im using the root user but when I hit the login button I have 3 error messages (red popup like on the login screen).

#2002 - php_network_getaddresses: getaddrinfo failed: Name does not resolve — The server is not responding (or the local server's socket is not correctly configured).

mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed: Name does not resolve

mysqli_real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name does not resolve

It seems to me that PMA cannot reach a database or something like that.
