### Pod Selector
The `.spec.selector` field is a pod selector. It works the same as the `.spec.selector` of
a [ReplicationController](replication-controller.md).

If specified, the `.spec.template.metadata.labels` must be equal to the `.spec.selector`, or it will
be rejected by the API. If `.spec.selector` is unspecified, it will be defaulted to

`.spec.template.metadata.labels`.
Also you should not normally create any pods whose labels match this selector, either directly,
