10.5.3. Creating a service by using the CLI

Procedure

1. Edit the VirtualMachine manifest to add the label for service creation. Add special: key to the spec.template.metadata.labels stanza:

   apiVersion: kubevirt.io/v1
   kind: VirtualMachine
   metadata:
     name: example-vm
     namespace: example-namespace
   spec:
     runStrategy: Halted
     template:
       metadata:
         labels:
           special: key
   # ...

   注記

   Labels on a virtual machine pass through to the pod. The special: key label must match the label in the spec.selector attribute of the Service manifest.

2. Save the VirtualMachine manifest file to apply your changes.

3. Create a Service manifest to expose the VM:

   apiVersion: v1
   kind: Service
   metadata:
     name: example-service
     namespace: example-namespace
   spec:
   # ...
     selector:
       special: key
     type: NodePort
     ports:
       protocol: TCP
       port: 80
       targetPort: 9376
       nodePort: 30000

   • spec.selector defines the label that you added to the spec.template.metadata.labels stanza of the VirtualMachine manifest.
   • spec.type defines the type of service by the way it is exposed. Choose one of ClusterIP, NodePort, or LoadBalancer.
   • spec.ports defines a collection of network ports and protocols to expose from the virtual machine.
4. Save the Service manifest file.

5. Create the service by running the following command:

   $ oc create -f example-service.yaml

6. Restart the VM to apply the changes.
