Names
All objects in the Kubernetes REST API are unambiguously identified by a Name and a UID.
For non-unique user-provided attributes, Kubernetes provides labels and annotations.
See the identifiers design doc for the precise syntax rules for Names and UIDs.
Names
A client-provided string that refers to an object in a resource URL, such as /api/v1/pods/some-name.
Only one object of a given kind can have a given name at a time. However, if you delete the object, you can make a new object with the same name.
By convention, the names of Kubernetes resources should be up to maximum length of 253 characters and consist of lower case alphanumeric characters, -, and ., but certain resources have more specific restrictions.
UIDs
A Kubernetes systems-generated string to uniquely identify objects.
Every object created over the whole lifetime of a Kubernetes cluster has a distinct UID. It is intended to distinguish between historical occurrences of similar entities.
