Upload Helm charts to OCI registry and sign them with cosign #221
Description
Summary
With Helm v3.8.0, the OCI support became GA, which is an excellent chance to start publishing Helm charts to OCI-compliant registries.
Use cases
OCI registries are widely adopted and are fast becoming the standard. Now that Helm supports these by default it would be nice if 1p could push their charts to an OCI registry, e.g. ghcr.io.
Using the OCI standard also allows for the charts to be signed with cosign. This will provide a way for end users to check the integrity of the charts.
Proposed solution
Publish charts to an OCI registry like ghcr.io.
