Namespaces

In Kubernetes, namespaces isolate groups of resources within a single cluster. Resource names must be unique within a namespace, but not across namespaces.

Namespace names must be unique within a cluster. Avoid creating namespaces called test or similar generic names.

When a user logs into the Rancher GUI for the first time, a Personal Project and a Namespace are created automatically. If you do not see them, reload the web page.

You can view your namespaces in the Rancher GUI under the Project/Namespaces tab in the left sidebar.

You can create additional namespaces either with kubectl or in the Rancher GUI. However, creating namespaces with kubectl is not recommended because these namespaces are not linked to the user’s Project. Instead, create a namespace in the Rancher GUI’s Namespace overview page by clicking the Create Namespace button.
