@param namespace Namespace defines the space within which each name must be unique. An empty namespace is equivalent to the &#34;default&#34; namespace, but &#34;default&#34; is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty.

Must be a DNS_LABEL. Cannot be updated. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces
