We also need a maintainer to make this package public

ghcr.io/kubernetes-sigs/headlamp/charts/headlamp

AFAIU, we are not supposed to use ghcr.io but the official Kubernetes registry for that. I need some time to go over that and understand exactly how to publish it.

Ugh, yeah that makes sense. I honestly forgot headlamp needed to follow kubernetes-sigs guidelines now that it's part of the org. There's a lot of effort in even getting older apps charts to publish to OCI...

• csi-driver-nfs: Please publish Helm Chart to OCI kubernetes-csi/csi-driver-nfs#618
• descheduler: Publish helm chart also as an OCI package (e.g. on GHCR registry) descheduler#1470
• external-dns: Publish helm charts also as an OCI package external-dns#4630
• metrics-server: Publish helm chart also as an OCI package (e.g. on GHCR registry) metrics-server#1527

Although some had success...

• ingress-nginx: Helm chart OCI support kubernetes/ingress-nginx#13513
• node-feature-discovery: Request: Upload Helm chart to OCI registry node-feature-discovery#2091

Good luck on figuring it out because it seems like there is no clear indication of how to proceed.

I wonder what needs to be done on this PR?

@onedr0p Do you still want this merged in? It's not clear to me.

Pull request overview

This PR fixes the package pattern in the Helm chart release workflow to specifically match .tgz files instead of all files in the .cr-release-packages/ directory. This change was identified as needed during review of PR #3024, which introduced the functionality to push Helm charts to GitHub Container Registry (GHCR) as OCI artifacts.

Changes:

• Updated glob pattern from .cr-release-packages/* to .cr-release-packages/*.tgz to specifically target packaged Helm chart files
• Removed an extraneous blank line for cleaner formatting
