In the Container Service for Kubernetes (ACK) console, you can create a ConfigMap on the ConfigMap page or from a YAML template. You can use ConfigMaps to store configuration information that does not need to be kept confidential. This topic describes how to manage ConfigMaps.

Prerequisites

An ACK cluster is created. For more information, see Create a managed Kubernetes cluster.

Create a ConfigMap

Create a ConfigMap on the ConfigMap page

  1. Log on to the ACK console.
  2. In the left-side navigation pane, click Clusters.
  3. On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
  4. In the left-side navigation pane of the details page, choose Configurations > ConfigMaps.
  5. On the ConfigMap page, select the namespace to which the ConfigMap belongs from the Namespace drop-down list, and click Create in the upper-right corner of the page.
  6. In the Create panel, enter a name for the ConfigMap, click + Add to enter keys and values, and then click OK.
    • ConfigMap Name: Required. The name of the ConfigMap. The name can contain lowercase letters, digits, hyphens (-), and periods (.). Other resource objects must reference the ConfigMap name to obtain configuration information.
    • ConfigMap: Enter configuration information in key-value pairs. You can also click Import to create the ConfigMap from a file.
  7. Click OK.

    After the ConfigMap is created, you can find the newly created ConfigMap named test-config on the ConfigMap page.
