Is this possible to tag docker images with latest only when it's not a prerelease ?

[eddycharly]

We are using goreleaser to build docker images (with ko), and configured prerelease: auto.

Now we don't want to tag images with latest when it is a prerelease (we want latest only on stable releases).

Our config looks like this:

kos:
  - repository: ghcr.io/kyverno/playground
    tags:
      - '{{.Tag}}'
      - latest # can we make this conditional to exclude prereleases ?

Is there a syntax (template) we can use for that ?

kos:
  - repository: ghcr.io/kyverno/playground
    tags:
      - '{{.Tag}}'
      - '{{ if not .Prerelease }}latest{{ end }}' 

Can you check if this works?

EDIT: fixed typo

Looks like this worked (without #4043)

are you sure?

seems like the push without a tag defaulted to :latest:

Oh, missed that, thanks !

Tested again with main, seems good this time https://github.com/kyverno/playground/actions/runs/5101130326/jobs/9169790907#step:9:316

Thank you !
