An ImagePolicy configuration for Calver format and an optional tag suffix

[0xStarcat]

👋🏼 felt like sharing an ImagePolicy configuration I figured out that works with Calver format + an optional tag suffix (ie: -hotfix1)
It uses the semver policy to extract and transform the components into semver format for internal comparison. It works only when your Calver format uses 0-padded dates like YYYY-0M-0D.PATCH (patch is optional too)

apiVersion: image.toolkit.fluxcd.io/v1beta2
kind: ImagePolicy
metadata:
  name: foo
  namespace: bar
spec:
  filterTags:
    pattern: ^v(?P<YEAR>\d+)\.(?P<MONTH>\d+)\.(?P<DAY>\d+)\.(?P<PATCH>\d+)(-hotfix(?P<QUANTIFIER>\d+))?$
    extract: $YEAR$MONTH$DAY.$PATCH.${QUANTIFIER}0
  policy:
    semver:
      range: ">=0.0.0"

tested with the following tags being detected earliest to latest:

1. v2024.06.08.0
2. v2024.06.08.0-hotfix1
3. ... v2024.06.08.0-hotfix10
4. v2024.06.08.1
5. v2024.06.09.0
6. ... v2024.06.09.10
7. ... v2024.06.09.10-hotfix1
8. v2024.06.10.0
