Exactly this. It checks periodically if a newer image for the tag of the container is available (e.g. vaultwarden:latest) and tells you about it. You can setup mail, sms, Teams, you name it.

So then you know a new version is available, can check the changelog and decide if the update is worth it.

Personally having great results with Diun. Same idea (check for newer container image) and works 100% for me.

Don’t know if it can automatically load and restart containers, rather do that personally.

Been using it for quite a while now, just does what it says on the tin without a hassle.

I’d say commit. If you just want to encrypt files in the cloud, it does so without getting in the way
