A new Kubernetes namespace, with your workspace name, is created in the management cluster. All workspace assets are created in this new namespace. The namespace name cannot be changed but the display name and description can be modified.
From the workspace selection dropdown at the top of the screen, select the workspace you want to edit. Select the Actions drop-down button and select Edit Workspace.
Edit Workspace Advanced Options
When creating or editing a workspace, you can use the Advanced Options to add, edit, or delete annotations and labels to your workspace. Both the annotations and labels are applied to the workspace namespace.
Labels that are added to a workspace, are also applied to all the clusters in the workspace.
