These are the steps to setup the current website in a Docker container. The setup uses docker-compose to declaratively describe a two-container application: a MySQL 5.5 database and a WordPress frontend. Docker links tie them together so that the web container can reach the database by hostname, without needing to hard-code any IP addresses or manage networking manually. A single docker-compose up command downloads the required images and starts both containers, with port 80 on the host forwarded into the WordPress container.

wget -O- https://github.com/docker/compose/releases/download/1.2.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

mkdir wordpress
cd wordpress

Then create a file fig.yml which contains:

db:

  environment:
    MYSQL_ROOT_PASSWORD: "A VERY STRONG PASSWORD"
web:
  image: wordpress:latest
  ports:
    - "80:80"
  links:
    - db:mysql

This description takes advantage of a Docker feature to bind together two or more containers: Docker links. We use it to make the WordPress container depends on another container with MySQL 5.5.

The `docker-compose up` command will read `fig.yml`, download the needed data and deploy the two containers.

/usr/local/bin/docker-compose up

Et voilà, the port 80 of the host which runs the container will be forwarded to the port 80 of the WordPress container.
