Is it possible to get notifications only when new versions are available while using the latest tag?

[rafapirotto]

Hey! First of all thanks for this amazing piece of software!

Secondly, I want to explain my use case (if it makes sense at all).

I'm interested in knowing whenever a new version (be it a major, minor or patch) is available. I wanna know if that is possible while using the latest tag together with the watch digest flag turned off. Like, can wud obtain the version from the latest tag? Does it make sense to do so?

Like when will I get a notification if I set a container with the latest tag but turn off the watch digest flag?

The motivation behind this is avoid setting a fixed semver tag to all of my images

Thanks!

Hi,

Thank you for your support 👍 .

Unfortunately the primary goal of wud is to stop using latest tags 😄... in favour of semver tags to ensure container immutability.

If I understand what you look for, you'd expect wud to:

1. Get the digest of the running container with tag latest (let's call it digest_current)
2. Find on the registry if this digest_current is also associated to another semver tag (let's call it semver_tag_current)
3. Get on the registry the digest associated to the latest tag (let's call it digest_registry)
4. Find on the registry if this digest_registry is also associated to another semver tag (let's call it semver_tag_registry)
5. Compare the 2 semver tags
6. Trigger a notification indicating that semver_tag_registry is greater than semver_tag_current (or that digest_registry is newer than digest_current)

It seems very complicated to implement (I don't even know if it's possible using the Docker Registry API by the way 🤔 ).

I suspected I was doing something wrong! Thanks a lot!
