Are there any concerns/risks to using Watchtower? (alien.top)

Someone recommended it for keeping my containers up to date automatically. I checked out the repo and it seems too good to be true. It just updates your containers when a new image is available and everything just works out of the box? I'm a bit scared of just leaving it alone in case it might break something. The fact that it doesn't come with a gui also scares me a bit.

Does anyone here use it and can recommend it? Any horror stories?

I've been using watchtower for more than a year on all my containers and no issues so far. I have read many warnings against automating the updates, but it has never broken anything in my case. I'm talking about 3 VMs (on Proxmox) and 2 Synology boxes. 5 instances of watchtower keeping a total of 84 containers updated.

Nonetheless I try to play it on the safe side and make daily backups in case something breaks. I've had a couple of containers breaking (nothing related to watchtower, AFAIK) and I have recovered easily restoring the latest backup.

Using Watchtower for approximately 2 years on about 20 Containers. I had 1 issue, where a container would not start after the update. The Error Message said I had an unsupported entry in the configuration file of the app. I looked up the changelog of that app, and found out that the option was removed and replaced by something else. Had to change one line in the configuration. Not really a problem for me.

Though I decided to exclude my Home Automation Container and my kasm container ( my gateway to my network, a bit like guacamole ). Those may pose problems if they are offline unexpected.
