I installed Home Assistant with Dokku. It was very easy, but there were a couple of gotchas that slowed it down a bit.
Setup
Create a new homeassistant app in Dokku
dokku apps:create homeassistant
Set the timezone
dokku config:set homeassistant TZ=America/Chicago
Create a folder that will be used for Home Assistant configuration
mkdir /path/to/my-config
dokku storage:mount homeassistant /path/to/my-config:/config
Home Assistant uses its own init procedure, and we need to disable automatic init
dokku scheduler-docker-local:set homeassistant init-process false
Initialize Home Assistant app from its docker image
dokku git:from-image homeassistant ghcr.io/home-assistant/home-assistant:stable
Dokku didn’t correctly configure the correct port for the container, so:
Remove the default proxy port if needed:
dokku proxy:ports-remove homeassistant http:80:5000
Add the correct proxy port:
dokku proxy:ports-add homeassistant http:80:8123
To enable autodiscovery, Home Assistant needs to be connected to the host network. Other than autodiscovery, I had no issues using the default network and normal port mapping.
You can enable this option in dokku with
dokku docker-options:add homeassistant deploy,run "--network=host"
Once Home Assistant is on the host network, dokku’s zero-downtime restarts will fail when updating or restarting the service, because the bound port will already be in use.
Zero downtime restarting can be disabled with
dokku checks:disable homeassistant
Updating Home Assistant
To update Home Assistant, use git:from-image again, pointing to the newest SHA digest for your architecture (instead of using the :stable tag)
dokku git:from-image homeassistant ghcr.io/home-assistant/home-assistant@sha256:<shadigest>
You can get this digest from docker hub for your architecture: docker hub, or you can pull the image locally and use:
docker inspect --format='{{index .RepoDigests 0}}' ghcr.io/home-assistant/home-assistant:stable
My favorite automations (so far) turn my printer’s light off automatically after a print completes, and lets me know to open windows when the weather is cooler and less humid outside, and air quality is ok.
