The Deployment "deployment-2" is invalid: spec.template.spec.containers[0].name: Invalid value: "test-pod-name-longer-than-63-characters-making-it-an-invalid-dns-label": must be no more than 63 characters

OK... well I suppose its impossible to create a Pod with a name this size. So, this test is not needed... validation happens in the API.

edit: no - the manifest was wrong - I was setting the container name, not the Pod name itself. Curiously container name is validated as a dns label, even though it's not used in the DNS spec as a label.

Damn. Looks like the process that spins up pods for a deployment will truncate the deployment name when constructing the pod name, such that it will be 63 characters, including the pod instance id.

So, to test we will need to create Pods directly.
