10.6. Accessing a virtual machine by using its internal FQDN

Procedure

1. Create a Service manifest to expose the VM, such as the following example:

   apiVersion: v1
   kind: Service
   metadata:
     name: mysubdomain
   spec:
     selector:
       expose: me
     clusterIP: None
     ports:
     - protocol: TCP
       port: 1234
       targetPort: 1234

   • metadata.name defines the name of the service. This must match the spec.subdomain attribute in the VirtualMachine manifest file.
   • spec.selector defines the service selector that must match the expose:me label in the VirtualMachine manifest file.
   • spec.clusterIP defines a headless service.
   • spec.ports defines the list of ports that are exposed by the service. You must define at least one port. This can be any arbitrary value as it does not affect the headless service.
2. Save the Service manifest file.

3. Create the service by running the following command:

   $ oc create -f headless_service.yaml
