I have also started a project using a Raspberry Pi Zero W which interfaces to a LinkMaster 850LM so that I can press the buttons on my Subaru to activate some automations via a MQTT message. The containers include home-assistant which interfaces to the Z-Wave USB stick, node-red which sets up automations, and pertainer which is used to manage containers in Docker. I originally set-up the containers using a docker-compose script that I found on the home-assistant blog. I will be changing those docker-compose scripts as I go.
Right now I am attempting to understand how to control lights via triggers so that I will be able to set-up automations that will work pretty much the first time. I am also exploring a couple of different dashboard layouts. All of this is actually controllable via web interfaces, so I am able to push the ports through a router (Netgear FVS318N) to my media vlan so that I am able to get to the web interfaces easily.
