This topic describes how to create a namespace in a Kubernetes cluster.

Background information

In a Kubernetes cluster, you can use namespaces to create multiple virtual clusters. If multiple users share a cluster, you can create namespaces to divide workspaces and assign cluster resources to different tasks. You can use resource quotas to assign resources to namespaces.


  1. Log on to the ACK console.
  2. In the left-side navigation pane, click Clusters.
  3. On the Clusters page, click the name of a cluster or click Details in the Actions column. The details page of the cluster appears.
  4. In the left-side navigation pane, click Namespaces.
  5. On the page that appears, click Create in the upper-right corner.
  6. In the dialog box that appears, configure the parameters.
    Configure parameters for a namespace
    • Name: Enter a namespace name. In this example, set the value to test. The name must be 1 to 63 characters in length, and can contain digits, letters, and hyphens (-). It must start and end with a letter or a digit.
    • Label: Add one or more labels to the namespace. You can use labels to identify the attributes of the namespace. In this example, use a key-value pair to identify that the namespace is used in a test environment.

      To add a label, enter a key and a value and click Add in the Actions column.

  7. Click OK.
    Return to the Namespace page. In the list of namespaces, the test namespace appears.
