Thanks for the additional feed back @dan-brown_0128!
We do have a thread about OCI Registries in ProGet, as they have been requested from time to time. It might be worth posting this there, too?
But our current take is that "OCI Registries are a poorly-designed solution in search of a misunderstood problem", and that they are technologically inferior to alternatives. Here's a quote from that post:
The main issue I have is that an OCI registry is tied to a hostname, not to a URL. This is not what users expect or want with ProGet -- we have feeds. Users want to proxy public content, promotion content across feeds, etc. None of this is possible in an OCI registry.
We got Docker working as a feed by "hijacking" the repository namespace to contain a feed name. Helm charts don't have namespaces, so this is a no go.
Personally I can't imagine how this is scalable. A lot of new Docker users (including me) are "shocked" that you have to include the "source" in the container name (e.g. proget.corp/my-docker-feed/my-group/my-app) -- I can't see how this could ever work to expand this to all deployment artifacts (e.g. my-artifacts.corp/my-group/my-app/service-assembly), especially considering how often everything is referenced in scripts and dependencies.
Anyways best to continue on that other thread if you'd like to keep the discussion going, we're always open to learning more :)
