Usage

Basic

To start:

$ docker run --rm -d --name my-mysql -e MYSQL_ROOT_PASSWORD=passwd mysql
$ docker run --rm -d --name my-wordpress --link my-mysql:mysql -p 80:80 wordpress

Then open http://localhost. It might take a minute to connect to the server successfully.

To stop:

$ docker stop my-mysql my-wordpress

You can change following values.

• my-mysql ... Name of the MySQL container.
• my-wordpress ... Name of the WordPress container.
• passwd ... Password for the MySQL DB.
• 80 ... Port to access the WP site. It can be like 8080:80 to access via http://localhost:8080.

Keep your data

Add -v or --volume options.

$ docker run --rm -d --name my-mysql -e MYSQL_ROOT_PASSWORD=passwd -v `pwd`/db:/var/lib/mysql mysql
$ docker run --rm -d --name my-wordpress --link my-mysql:mysql -p 80:80 -v `pwd`/wp:/var/www/html wordpress

Then keep directories db and wp.

If you prefer Windows, replace pwd and surrounding back quotes with %CD%.

Note: Remember you have to specify local directories in FULL PATH. ./db doesn't work.
