Quickstart: 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, make sure you 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 contains a docker-compose.yml file which is complete in itself for a good starter wordpress project.

    Tip: You can use either a .yml or .yaml extension for this file. They both work.

  2. Change into your project directory.

    For example, if you named your directory my_wordpress:

    cd my_wordpress/

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

    version: '3.3'

services:
   db:
     image: mysql:5.7
     volumes:
       - db_data:/var/lib/mysql
     restart: always
     environment:
       MYSQL_ROOT_PASSWORD: somewordpress
       MYSQL_DATABASE: wordpress
       MYSQL_USER: wordpress
       MYSQL_PASSWORD: wordpress

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     ports:
       - "8000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress
       WORDPRESS_DB_NAME: wordpress
volumes:
    db_data: {}

Notes:

  • WordPress Multisite works only on ports 80 and 443. {: .note-vanilla}

Build the project

Now, run docker-compose up -d from your project directory.

This runs docker-compose up in detached mode, pulls the needed Docker images, and starts the wordpress and database containers, as shown in the example below.

$ docker-compose up -d

Creating my_wordpress_wordpress_1

Note: WordPress Multisite works only on ports 80 and/or 443. If you get an error message about binding 0.0.0.0 to port 80 or 443 (depending on which one you specified), it is likely that the port you configured for WordPress is already in use by another service.

Bring up WordPress in a web 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 is not immediately available on port 8000 because the containers are still being initialized and may take a couple of minutes before the first load.

If you are using Docker Machine, you can run the command docker-machine ip MACHINE_VM to get the machine address, and then open http://MACHINE_VM_IP:8000 in a web browser.

If you are using Docker Desktop for Mac or Docker Desktop for Windows, you can use http://localhost as the IP address, and open http://localhost:8000 in a web browser.

Choose language for WordPress install

WordPress Welcome

Shutdown and cleanup

The command docker-compose down removes the containers and default network, but preserves your WordPress database.

The command docker-compose down --volumes removes the containers, default network, and the WordPress database.
