Hass.io with docker-compose

This is a simple docker compose file to run a full Hass.io system using docker-compose. The motivation for doing so is to avoid having to install additional packages on the host system. Also, in order to simplify installation on plain container OSes, like Container OS or RancherOS. It comes with a few limitations however, make sure to read about them below.

Caveats and limitations

Nothing is perfect, so here are few general things you need to know:

  • Currently only for x86_64 hosts (based on qemux86-64-homeassistant)
  • AppArmor not supported (maybe later)
  • You will get an error regarding rauc during startup (you can ignore it)
  • Since HassOS is not used, upgrade of OS is not supported (related to point above)

The supervisor in particular has a few quriks:

  • As it launches containers dynamically (e.g. homeassistant and all the addons), docker-compose will not be aware of these containers and cannot mange them them (e.g. stop or remove them)
  • It is designed to run on a system where no one can mess with docker. It will restart containers that crash, but if a container is manually stopped or removed (whilst the supervisor is running), it will treat that as a non-error and do nothing. So if you fiddle with the containers, you are on your down!
  • It keeps track of the last system boot. So if you restart only the supervisor, it will realize that and skip doing things (like re-creating containers). I found this to be a bit annoying, so the last boot tag is reset every time the supervisor is restarted. This makes sure that containers are re-created properly with the sacrifice of a tad slower startup time and maybe a few warnings about containers already running (that can be safely ignored). Just be aware of this.

Other things, like installing addons, upgrading Home Assistant and dealing with snapshots works correctly though 😊

Installation

  1. Install docker-compose according to your operating system, e.g. apt-get or pip install docker-compose in a virtual environment.

  2. Clone this repository:

$ git clone https://github.com/postlund/hassio-compose.git
  1. Create a .env file with SUPERVISOR_SHARE pointing to the directory where you want to store all configuration data. THIS MUST BE AN ABSOLUTE PATH!!!!
$ cd hassio-compose
$ echo "SUPERVISOR_SHARE=/home/$USER/hassio-config" > .env
  1. Start Hass.io using docker-compose:
$ docker-compose up

Tips & tricks

Stopping Containers

To stop the supervisor, just run:

$ docker-compose down

This will not stop Home Assistant or any addons. To do that, run:

$ docker stop homeassistant
$ docker ps | grep " addon_" | cut -f 1 -d ' ' | xargs docker stop

Removing Containers

To remove the containers (stop them first), just do:

$ docker-compose rm
$ docker ps | grep " addon_" | cut -f 1 -d ' ' | xargs docker rm
