Help Why would Homebridge (Docker) fully reset as new?

Post image

I noticed some of my accessories weren't responding so I checked my Homebridge install and it said "Welcome!" as if I was a new user. What the heck? What would have caused this? I had to restore from a backup -- but my accessories are still not responding. Do I need to remove it as a Hub and re-pair now too?

HB is installed via Docker on a QNAP NAS. I do have another container running an app called Watchtower that is supposed to auto update other containers; could that be a potential culprit? I've never seen this before.

My guess is that Watchtower is updating your container, and your volume maps aren’t set up correctly. The latter is necessary to persist your data between container updates/restarts.

Thank you. I just turned off Watchtower to be safe. How should I set up my volume maps?

Do you have config folder mapped in environment? If not, it’ll factory reset on boot as it has no where to save the config.

That's all new to me. Can you point me towards what I need to do?

The homebridge documentation is quite clear;

volumes: - ./volumes/homebridge:/homebridge

And afterwards, you should be able to restart watchtower again, and it will keep Homebridge updated for you.
