I’m trying to set system environment variables on the HA docker in a supervised install. Searching the forums mentions ways to do this on an rpi install using /home/pi/.homeassistant/ha.env or editing /etc/systemd/system/home-assistant.service but this doesn’t apply to supervised installs on Debian x64.
I tried editing the HA docker environment variables directly in Portainer but the supervisor reverts to the original container, which makes sense.
What’s the correct way to set HA environment variables?
For context, I’m trying to set a MASS_BASE_URL environment variable due to having a dual-homed install.
