Used on: Namespaces
Kubernetes API Server defaults this label to the namespace name during admission. This label can be used with any namespace selector, as an example with NetworkPolicy objects.
When the `NamespaceDefaultLabelName`
[feature gate](/docs/reference/command-line-tools-reference/feature-gates/) is enabled,
the Kubernetes API server sets this label on all namespaces. The label value is set to
the name of the namespace.
This is useful if you want to target a specific namespace with a label
{{< glossary_tooltip text="selector" term_id="selector" >}}.
