Request: Upload Helm chart to OCI registry

[heavybullets8]

Is this a new feature, an improvement, or a change to existing functionality?

New Feature

Please provide a clear description of the problem this feature solves

Currently, Helm charts are not available as OCI artifacts, limiting options for signing, integrity verification, and compatibility with GitOps workflows such as Flux. Publishing charts as OCI artifacts would enable secure distribution and streamlined reconciliation using GitOps tooling.

Feature Description

With Helm v3.8.0, OCI support became GA, enabling Helm charts to be published directly to OCI-compliant registries like Quay, Dockerhub, and GHCR. This allows signing charts using cosign, ensuring integrity and enabling secure GitOps workflows, particularly with Flux, which can reconcile and verify OCI artifacts.

Describe your ideal solution

Publish and distribute Helm charts as OCI artifacts to an OCI-compliant registry, supporting integrity verification via cosign signatures. This allows Flux and similar GitOps tools to securely reconcile these charts directly from OCI sources.
