[Feature Request]: Add a latest-release tag to the docker image

[DanielWeigl]

Is your feature request related to a problem? Please describe.

Currently each commit on master triggers a new tag on your docker image and releases dont have a dedicated tag. We have an automated update check on our cluster (keel) which automatically depolys the most recent version if a tag gets updated.

Describe the solution you'd like

Can you add here and here something along:

type=semver,pattern=v{{major}}-latest

(untested)

So that its possible to subscribe to the most recent major version tag.

Describe alternatives you've considered

and releases dont have a dedicated tag

They do though, so I'm not sure what problem we're solving here.

You can def see the master and dev builds, but under that, you see the tagged releases.

Yes, but its not possible to use one tag (eg. v6-latest or latest-release) to get the most recent release. If you follow the tag master or latest we get an update for each push to master, which not necessarily is a release. And if you subscribe to an explicit release tag (v6.1.0) we would never get automated updates.
