WordPress on Docker

Hosting the WordPress Dev Environment

My first inclination for WordPress dev environment was to look for free cloud hosting the could support Wordpress. I was least inclined to install directly onto my laptop, and deal with potentially conflincting with my other local dev environments. Given that I already have Docker For Mac running, I decided to go the Docker route.

WordPress on Docker

To learn how to setup Wordpress on Docker, I followed this, that, and the other guide.

Below is the docker-compose.yml file used to setup WordPress, MySql, and PhpMyAdmin. The main features:

• DB data persisted in a docker volume named wp_db_data
• Wordpress site files stored on host in the wp folder
• PhpMyAdmin in it's own container to manage the DB

version: '2'

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

   wordpress:
     depends_on:
       - db
     image: wordpress:latest
     volumes:
       - ./wp:/var/www/html
     ports:
       - "8000:80"
     restart: always
     environment:
       WORDPRESS_DB_HOST: db:3306
       WORDPRESS_DB_USER: wordpress
       WORDPRESS_DB_PASSWORD: wordpress

   phpmyadmin:
     depends_on:
       - db
     image: phpmyadmin/phpmyadmin
     container_name: phpmyadmin
     environment:
       - PMA_ARBITRARY=1
       - PMA_HOST=db
     restart: always
     ports:
       - 8080:80
     volumes:
       - /sessions

volumes:
    wp_db_data:

Create a directory where you want the Wordpress site to exist, eg:

mkdir -p ~/dev/wpdocker/wp
cd ~/dev/wpdocker
vi docker-compose.yml
# copy the contents above, edit as needed, then:
docker-compose up

Point your browser at localhost:8000, and you should see the initial WordPresss install dialog:

Follow through the basic installation, and you should be rewarded with something like this:
