Problem Description

No problem, just an enhancement of the chart publish workflow

Proposed Solution

The helm chart is published using the classic approach with a static webserver and an index.yaml (GitHub pages).

helm repo add dex https://charts.dexidp.io
helm install --generate-name --wait dex/dex

However in helm 3.8+ the OCI method went GA:

• https://helm.sh/docs/topics/registries/
• https://github.com/helm/helm/releases/tag/v3.8.0

I'd like to push the packaged helm charts also on ghcr.io (right besides the already existing container images) so we can pull/install the helm chart like this:

helm install dex oci://ghcr.io/dexidp/helm-charts/dex --version x.y.z

Alternatives Considered

Still using the classic approach with GitHub pages and the index.yaml

Additional Information

none

any news on this request ?

[mkilchhofer]

@nlamirault seems like @sagikazarmark requested a small change and then I assume the dex maintainers would accept your PR
