Wordpress Development Environment with Docker

14 Sep 2015

WordPress is an awesome CMS but setup a WordPress development environment could be a bit painful.

First of all you need a LAMP stack or something similar. Then you need to download a copy of WordPress, copy your theme (or plugin) and finally install WordPress.

Well, fortunately we are in 2015 and someone has invented something to make our life easier:

Docker is a platform that allows the creation of containers to setup development and production environments. So we can turn all that painfull process into a piece of cake.

Let’s do it.

First of all you need to install Docker Toolbox. Docker Toolbok installs all dependencies to use Docker. If are you using Linux, you can install manually.

Create a new docker machine and load his env variables:

docker-machine create --driver virtualbox default
eval "$(docker-machine env default)"

Create a file named docker-compose.yml in your theme’s root:

  image: wordpress
    - database:mysql
    - 8080:80
  working_dir: /var/www/html
   - .:/var/www/html/wp-content/themes/my-theme/

  image: mariadb
    MYSQL_ROOT_PASSWORD: somepassword

This file tells to Docker run two containers: wordpress using the wordpress image and database using the mariadb image.

If are you developing a plugin, just need to change the path of the volumes option.

With the docker-compose.yml file created we are ready to go! Just run:

docker-compose up

Wait it finishes and open http://localhost:8080.

If you’re in OSX, will need to access the VM directly. Get the machine IP running:

docker-machine ip default

Open http://<machine-ip>:8080 and you will see the WordPress installation page.

Proceed with WordPress installation, login and activate your theme.

Done! :)
