It is recommended that the `expost.core.ingress` field be changed to optional

What can we help you?

Currently ExternalURL and expost.core.ingress fields are required, can they be changed to not required? Currently we have a scenario where we only need to access the Harbor backend service, and it is accessed inside the k8s cluster, so it can be accessed through the service ClusterIp type of harbor core.

ExternalURL is a required configuration for the harbor-core because the harbor-core uses this configuration to generate the auth service URL.

ingress can be changed to not required
