Quickstart: Docker Compose and WordPress

You can use Docker Compose to easily run WordPress in an isolated environment built with Docker containers. This quick-start guide demonstrates how to use Compose to set up and run WordPress. Before starting, you'll need to have Compose installed.

Define the project

1. Create an empty project directory.

   You can name the directory something easy for you to remember. This directory is the context for your application image. The directory should only contain resources to build that image.

   This project directory will contain a docker-compose.yaml file which will be complete in itself for a good starter wordpress project.

2. Change directories into your project directory.

   For example, if you named your directory my_wordpress:

    $ cd my-wordpress/
   

3. Create a docker-compose.yml file that will start your Wordpress blog and a separate MySQL instance with a volume mount for data persistence:

    version: '2'
    services:
      db:
        image: mysql:5.7
        volumes:
          - "./.data/db:/var/lib/mysql"
        restart: always
        environment:
          MYSQL_ROOT_PASSWORD: wordpress
          MYSQL_DATABASE: wordpress
          MYSQL_USER: wordpress
          MYSQL_PASSWORD: wordpress
   
      wordpress:
        depends_on:
          - db
        image: wordpress:latest
        links:
          - db
        ports:
          - "8000:80"
        restart: always
        environment:
          WORDPRESS_DB_HOST: db:3306
          WORDPRESS_DB_PASSWORD: wordpress
   

   NOTE: The folder ./.data/db will be automatically created in the project directory alongside the docker-compose.yml which will persist any updates made by wordpress to the database.

Build the project

Now, run docker-compose up -d from your project directory. This will pull the needed images, and then start the wordpress and database containers.

If you're using Docker Machine, then docker-machine ip MACHINE_VM gives you the machine address and you can open http://MACHINE_VM_IP:8000 in a browser.

At this point, WordPress should be running on port 8000 of your Docker Host, and you can complete the "famous five-minute installation" as a WordPress administrator.

NOTE: The Wordpress site will not be immediately available on port 8000 because the containers are still being initialized and may take a couple of minutes before the first load.
