was probably much easier on NUC than hassio based Raspberry PI.
I cloned the repo to:
Made the changes required to get it to compile on ARM and then added in a config.json / build.json to allow it to build for Hassio.
I was then playing around to see if i could get a config to work, thinking that the labels were applied to the hera container! Oops!
When i tried to build the repo directly in portainer it wouldn’t work, however building in Hassio worked, so i just built it and in portainer duplicated hera into another project. It then needed to be edited to use the “host” network which homeassistant uses.
I then had to run portainer in “leave_front_door_open”: “true” mode to be able to edit the homeassistant container (Yes i know we shouldnt).
And also made a slight tweak to the configuration is suggests. Within the homeassistant container I put the .pem key into SSL and then mounted /mnt/data/supervisor/ssl to /certs and also /var/run/docker.sock mounted to /var/run/docker.sock
I’d love to be able to build a module to make this easy, but from what I can see you cannot apply labels onto docker containers via a HASSIO addon.
