Namespaces

Namespaces logically isolate resources in a Kubernetes cluster. Namespaces are suitable when there are many users across multiple teams or projects. For clusters with only a few to a few dozen users, you generally do not need to create or consider namespaces. Object names within a namespace must be unique. After a Kubernetes cluster is created, the kube-public, kube-system, kube-node-lease, and default namespaces are created by default.

For a detailed introduction to namespaces, see the Kubernetes official documentation – Namespaces.

Entry: On the cloud management platform, click the navigation menu in the upper left corner, then click “Resource Management/Kubernetes/Clusters/Namespaces” in the left sidebar to open the Namespaces page.
