Services lose "endpoints"

[CiraciNicolo]

What happened?

With different Ingress Controller, such as Traefik and Nginx, the service used to route traffic "lose" endpoints. This results in Ingresses not working:

Service "harbor-system/harbor-portal" does not have any active Endpoint

What did you expect to happen?

Services should not lose endpoints

How can we reproduce it (as minimally and precisely as possible)?

• Deploy a VCluster
• Deploy an Ingress Controller inside vCluster
• Expose some services

Anything else we need to know?
