hpa in 1.26 k8s is not mapped properly

[EvgeniGordeev]

Scenario

• Chart https://github.com/codecentric/helm-charts/tree/master/charts/keycloakx version 2.1.1 was deployed to EKS cluster 1.24. In this chart version HorizontalPodAutoscaler was defined with apiVersion: autoscaling/v2beta2 https://github.com/codecentric/helm-charts/blob/653a238737a8d8a665913d23503cdc44bfa8bcd2/charts/keycloakx/templates/hpa.yaml
• Cluster got upgraded to 1.26
• Trying to upgrade keycloak chart 2.1.1 -> 2.2.1 caused. This time apiVersion is autoscaling/v2 https://github.com/codecentric/helm-charts/blob/edcf6b2b7d1ff601bd15b5ee89f05397ffdb0821/charts/keycloakx/templates/hpa.yaml

Problem

Cannot upgrade or uninstall the chart:

uninstall.go:117: [debug] uninstall: Failed to delete release: [unable to build kubernetes objects for delete: resource mapping not found for name: "RELEASE_NAME-keycloakx" namespace: "default" from "": no matches for kind "HorizontalPodAutoscaler" in version "autoscaling/v2beta2"

Helm manifest still has deprecated apiVersion:

helm get manifest RELEASE_NAME
...
apiVersion: autoscaling/v2beta2
kind: HorizontalPodAutoscaler
metadata:
  name: RELEASE_NAME-keycloakx
...

Probably related to #108

[danopia]

I believe these all include the fix to add HPA's deprecation:

• https://github.com/helm/helm-mapkubeapis/pull/108
• https://github.com/helm/helm-mapkubeapis/pull/117
• https://github.com/helm/helm-mapkubeapis/pull/119
• https://github.com/helm/helm-mapkubeapis/pull/121
• https://github.com/helm/helm-mapkubeapis/pull/122
• #125
• #126
• #127

As a user, clearly this is something many people are hitting, I'd love to see a merge happen

Has this problem been fixed in a release yet? I just hit this same issue where it does not pick up the obsolete apiVersion for HPA.

EDIT: I confirmed this is not working in the latest version of the plugin. Can we get this in a release ASAP please?

The best you can do it's to use one of the unmerged MR from danopia post https://github.com/helm/helm-mapkubeapis/issues/116#issuecomment-1698541924

or create your own by cherry-picking.

Project seems dead...

This fix has been merged and will be in the next release.
