After this is merged and we have "production confirmation" that it works as we expect we showed follow-up on:

• check if we are also able to promote the charts to registry.k8s.io
• drop the old build method (release artifacts)
• update the install related documentation

A package publication on https://artifacthub.io/ whould be nice as a follow up, too.

Assuming that we can promote the image there. If it doesn't work, we can revert this PR.

It looks like the objects are properly listed in gcr.io/k8s-staging-kueue/charts/kueue

Should it be gcr.io/k8s-staging-kueue/kueue/charts instead?

[alculquicondor]

Also, can you test those objects to see if they work properly?

• It looks like the objects are properly listed in gcr.io/k8s-staging-kueue/charts/kueue

  Should it be gcr.io/k8s-staging-kueue/kueue/charts instead?

It's possible to change the path but Helm creates a subdirectory for the chart at the end. So if we change it, the resulting path would be gcr.io/k8s-staging-kueue/kueue/charts/kueue.

• Also, can you test those objects to see if they work properly?

It seems to be working as expected, I ran:

helm install kueue oci://gcr.io/k8s-staging-kueue/charts/kueue --version v20240619-v0.8.0-devel-54-g81ad017a

I left a question in the k8s-infra slack channel https://kubernetes.slack.com/archives/CCK68P2Q2/p1718819420490889

[BenTheElder]

Nobody should be consuming from gcr.io/k8s-staging-kueue directly anyhow (in fact we will have to move the staging locations to artifact registry later this year) so the path doesn't matter all that much there, when promoted to registry.k8s.io the path can be different.

[alculquicondor]

From slack thread:

Please start publishing staging images for kueue to us-central1-docker.pkg.dev/k8s-staging-images/kueue

Because #2476 didn't merge and I don't know if it's safe to do so.
