This take a legacy Helm repo and serve it as OCI registry.
- Turn legacy Helm repo into OCI Helm repo
- Cache with GCS.
Some potential features we can add:
- Add namespace so we can add proxy multiple legacy helm repos, probably with a config file.
- Add caching with S3.
- Remove dependency on Helm CLI.
I'm using Argo Helm as an example here.
