Last Updated:Sep 04, 2023

In the Container Service for Kubernetes (ACK) console, you can create a ConfigMap on the ConfigMap page or by using a template. You can use ConfigMaps to store non-sensitive, unencrypted configuration information. This topic describes how to manage ConfigMaps.


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

Create a ConfigMap

  1. Log on to the ACK console. In the left-side navigation pane, click Clusters.

  2. On the Clusters page, click the name of the cluster that you want to manage and choose Configurations > ConfigMaps in the left-side navigation pane.

  3. On the ConfigMap page, select the namespace in which you want to create a ConfigMap. Then, you can use one of the following methods to create a ConfigMap:

        • ConfigMap Name: the name of the ConfigMap. The name can contain lowercase letters, digits, hyphens (-), and periods (.). This parameter is required. Other resource objects must reference the ConfigMap name to obtain the configuration information.
        • ConfigMap: Enter the names and values of the ConfigMap in key-value pairs. You can also click Import to create the ConfigMap from a file.
