Sort of but not quite 12 factor wordpress.
What does it do?
Utilizes Docker, CoreOS and Confd to provide a sort of but not quite 12 factor wordpress.
The included example application will now be available via a port mapping so that you can interact with it:
$ vagrant up $ firefox http://localhost:8080
How it works ?
Vagrant spins up 3 coreos nodes, on the first node it spins up a docker registry and a mysql server ( caching both images for faster rebuilds ). It also builds a Wordpress Docker image that contains wordpress, and nginx+hhvm as well as confd ( and etcd ). A boot script sets up the environment including any default variables ( see
bin/boot for variables that can be changed by passing
docker run) and finally calls Supervisord to run the necessary apps. All apps called by cond pass their stdout back to confd which passes it back out to stdout so that
docker logs can see all activity.
Finally the wordpress container is started on each of the VMs utilizing environment variables to pass to confd to create a
wp-config.php file with database paths etc and a volume mount is used to mount the Vagrant shared wordpress files into the containers. Obviously in a production environment you wouldn't have a docker volume share, but creating a shared filesystem in the cloud is not a hard problem to solve and can be do in a container which is then volume mounted to wordpress.
