wordpress with Docker-Compose

Docker Compose is a tool for running multi-container applications on Docker defined using the Compose file format. A Compose file is used to define how the one or more containers that make up your application are configured.

Installation on ubuntu 18.04

sudo apt-get install docker-compose

docker-compose version

docker-compose version

Starts all containers in the working directory that have been stopped

docker-compose start

Stops all running containers in the current directory

docker-compose stop

Validates and displays configuration

docker-compose config

Lists all containers running in the working directory

docker-compose ps

This command stops and removes all containers in the working directory

docker-compose down

Configuring WordPress with Compose

create a wordpress-compose and navigate to it.

mkdir wordpress-compose && cd wordpress-compose

Setting up containers with Docker Compose works by creating a Dockerfile and docker-compose.yml in the desired working directory

create a docker-compose.yml file. This will tell docker how to configure and start the WordPress and MariaDB containers.

leafpad docker-compose.yml

wordpress:
    image: wordpress
    links:
     - mariadb:mysql
    environment:
     - WORDPRESS_DB_PASSWORD=password
     - WORDPRESS_DB_USER=root
    volumes:
     - ./html:/var/www/html
mariadb:
    image: mariadb
    environment:
     - MYSQL_ROOT_PASSWORD=password
     - MYSQL_DATABASE=wordpress
    volumes:
     - ./database:/var/lib/mysql
 

Using the command below, create new containers. This starts both containers in the background and leaves them running. If you wish to see the output from the containers just leave out the -d to deploy the applications in the foreground.

docker-compose up -d

-d running in foreground

You need to wait until the installation is complete. Once the process is complete, you’ll see something similar to the example output below.

Check the docker-compose log

Your WordPress server’s public IP address or domain can be viewed in your web browser to check the installation. The WordPress initial setup page should look like the image shown below.

sudo ifconfig docker0
