docker-compose wordpress mysql connection refused

Question

I\'ve created a small docker-compose.yml which used to work like a charm to deploy small WordPress instances. It looks like this:

wordpress:
  i         


        

Answer 1

To fix this issue the first thing to do is:

Add the following code to wordpress & database containers (in the docker-compose file):

restart: unless-stopped

This will make sure you Database is started and intialized before wordpress container trying to connect to it. Then restart docker engine

sudo restart docker

or (for ubuntu 15+)

sudo service docker restart 

Here the full configuration that worked for me, to setup wordpress with MariaDB:

version: '2'

services:
  wordpress:
    image: wordpress:latest
    links:
      - database:mariadb
    environment:
      - WORDPRESS_DB_USER=wordpress
      - WORDPRESS_DB_NAME=mydbname
      - WORDPRESS_TABLE_PREFIX=ab_
      - WORDPRESS_DB_PASSWORD=password
      - WORDPRESS_DB_HOST=mariadb
      - MYSQL_PORT_3306_TCP=3306
    restart: unless-stopped
    ports:
      - "test.dev:80:80"
    working_dir: /var/www/html
    volumes:
     - ./wordpress/:/var/www/html/
  database:
   image: mariadb:latest
   environment:
     - MYSQL_ROOT_PASSWORD=password
     - MYSQL_DATABASE=mydbname
     - MYSQL_USER=wordpress
     - MYSQL_PASSWORD=password
   restart: unless-stopped
   ports:
     - "3306:3306"
