Here at Playa, we love Docker. Docker allows us to deploy apps quickly and easily across a cluster of our cloud servers. Here's a little tutorial explaining how we dockerize our hosting environment.
A checklist of what we gonna do:
Some say that the idea of Docker is to run a single process in a container such that we need 3 containers in this case. Well, I am going to say that's absolutely not true.

In our case, that's our hosting service, so we are going to build one single container only.
Building the container is easy, for those of you who don't know what Dockerfile is, please refer to Dockerfile reference.
Here's our Github Repo for our docker image:

In docker series 2, we will introduce the use of docker swarm to manage a cluster of docker servers.
