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?

Thank you. What do you use for container backups and restoring?

Don't backup the actual container, backup the volumes and the docker-compose file

  • 3 VMs in Proxmox hosting 70 containers get backed up everyday with ProxmoxBackupServer (VM in my primary NAS) to a NFS mounted folder on my primary NAS
  • Primary NAS (with 7 containers) gets backed up with Snapshot replication to my secondary NAS everyday.
  • Secondary NAS (with 7 containers) gets backed up with Snapshot replication to my primay NAS everyday.
  • And once a month I backup my primary NAS (not the whole thing,only the important folders) to a USB drive that I store at a friends house.

Please take such advice with a large grain of salt. OP's experience is very much not the norm. Especially for more complex apps like Jellyfin or Nextcloud, it's almost guaranteed you'll break them if you just update blindly.
