Map Host Cluster Service to vCluster Service

For example, to map a service my-host-service in the namespace my-host-namespace to the virtual cluster service my-virtual-service in the virtual cluster namespace my-virtual-namespace, you can use the following config in your values.yaml:

mapServices:
  fromHost:
  - from: my-host-namespace/my-host-service
    to: my-virtual-namespace/my-virtual-service

With this configuration, vCluster will manage a service called my-virtual-service inside the virtual cluster that points to the host service my-host-service in namespace my-host-namespace. So pods inside the vCluster will be able to access the host service via e.g. curl http://my-virtual-service.my-virtual-namespace.

To apply this change to an existing vcluster instance, simply run the following command:

vcluster create <CLUSTER_NAME> -f values.yaml --upgrade
