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?

If you want highly available system, then you should perform updates with a custom made script, where you can control update issues. Otherwise watchtower is good.

If you have a script like this any chance you could open source it?

My script looks like this: https://gist.github.com/dgalli1/010fb978bae509dda43a1f31145a530f

And is ment to update docker-compose.yml files.

Great script! Only thing I can recommend is adding a "docker image prune -af" command after all compose files have had new images pulled and are up…unless you want old images taking up hard drive space/you have a valid reason for keeping old images.
