That won't do what he wants, I don't think.
$ kubectl run -i -t busybox --image=busybox --restart=Never -n
team-tectonic --overrides='{ "apiVersion": "v1", "spec": {"hostname":
"hello", "subdomain": "example"}}'
If you don't see a command prompt, try pressing enter.
/ # hostname -f
hello.example.team-tectonic.svc.cluster.local
/ #
Essentially he wants hostname and subdomain to combine and set the FQDN.
Not just the start of the FQDN. E.g. hello.example
