Upgrade Notices

Harbor is now leveraging our bb-common integration for network policies and istio-related resources. Please refer to this blog post for additional information on the integration.

The VirtualService for Harbor no longer includes a match on port 5000 for the registry. This port was not functional in typical deployments as no gateway was configured to listen on it, and all registry traffic (docker push/pull) routes through harbor-core.
