spec:
  running: false
  template:
    metadata:
      labels:
        special: key (1)

Save the VirtualMachine manifest file to apply your changes.

Create a Service manifest to expose the VM:

apiVersion: v1
kind: Service
metadata:
  name: example-service
  namespace: example-namespace
spec:
# ...
  selector:

Save the Service manifest file.

Create the service by running the following command:

$ oc create -f example-service.yaml

Restart the VM to apply the changes.
