ConfigMaps allow you to store non-sensitive, unencrypted configuration information and configuration files in Container Service for Kubernetes (ACK). This way, you can update configuration information without the trouble of rebuilding container images. This topic describes how to create and manage ConfigMaps.
Prerequisites
An ACK managed cluster or ACK Serverless cluster is created. For more information, see Create an ACK managed cluster or Create an ACK Serverless cluster.
Create a ConfigMap
Log on to the ACK console. In the left-side navigation pane, click Clusters.
On the Clusters page, click the name of the cluster that you want to manage and choose in the left-side navigation pane.
On the ConfigMap page, select the namespace in which you want to create a ConfigMap. Then, use one of the following methods to create a ConfigMap:
Method 1: Click Create
In the upper-right corner of the ConfigMap page, click Create.
In the Create panel, enter a name for the ConfigMap, click + Add, enter a key and a value, and then click OK.
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 import a JSON file to create the ConfigMap.
Method 2: Click Create from YAML
In the upper-right corner of the ConfigMap page, click Create from YAML.
On the page that appears, set the parameters and click Create.
Parameter
Description
Sample Template
You can select Custom from the drop-down list and configure the ConfigMap in YAML syntax. You can also select Resource - ConfigMap from the drop-down list. If you select Resource - ConfigMap, the ConfigMap is named aliyun-config and contains the following variable files:
game.propertiesandui.properties. You can modify the ConfigMap to meet your requirements.
After the ConfigMap named aliyun-config is created, you can find it on the ConfigMap page.
What to do next
After you create the ConfigMap, you can perform the following operations on the ConfigMap page:
If you update a ConfigMap, the applications that use the ConfigMap are affected.
Click the name of the ConfigMap to view the details of the ConfigMap and the configuration information that the ConfigMap contains.
Click Edit in the Actions column to update the ConfigMap. You can update the content in the Name and Value columns.
Click Edit YAML in the Actions column to update the ConfigMap. In the View in YAML panel, update the ConfigMap and click OK.
Click Delete in the Actions column to delete the ConfigMap if you no longer need the ConfigMap.
