Name

Every object in Kubernetes owns its own name that's uniquely identified within the same namespace. Kubernetes uses object names as part of a resource's URL for the API server, so it has be a combination of lowercase alphanumeric characters and dashes and dots, and it has to be less than 254 characters long. Besides the object name, Kubernetes also assigns a Unique ID (UID) to every object to distinguish historical occurrences of similar entities.
