You can host your own with harbor, and set up replication per repo (pull upstream tags) If you need a commercial product/support you can use MSR v4.
Harbor can install on any K8s cluster using helm, with just a couple of dependencies (cert-manager, postgres op, redis-op) Replication stuff you can easily add.
I have some no-warranty terraform I could share if there is some interest.
Sure, but does the rest of the world?
