Namespaces

Namespaces are used to logically isolate resources in a Kubernetes cluster. Namespaces are suitable for scenarios where there are many users across multiple teams or projects. For clusters with only a few to a few dozen users, there is no need to create or consider namespaces at all. Names of Kubernetes objects under namespaces must be unique. kube-public, kube-system, kube-node-lease-default namespaces are created by default after the Kubernetes cluster is created.

Please see Kubernets Official Documentation - Namespaces for more details on namespaces.

Entry: In the cloud management platform click the top left corner of navigation menu, and click “Containers/Clusters/Namespaces” menu item in the left menu bar that pops up to enter the Namespaces page.
