Managing ConfigMaps

A ConfigMap is used to store non-confidential data in key-value pairs. It is commonly used to store configuration information required by workloads. Applications read corresponding configurations from configuration files, command-line arguments, or environment variables.

Creating a ConfigMap

  1. Click the display name of the target workload cluster in the workload cluster list to enter the Overview page of the workload cluster.

  2. In the sidebar, click Configuration > ConfigMap.

  3. Click + Create ConfigMap.

  4. Configuration provides the following default YAML template, where you can configure relevant parameters as needed.

    apiVersion: v1
kind: ConfigMap    # The type of resource. This YAML configuration defines a ConfigMap.
metadata:
  name: example    # The name of the ConfigMap.
  namespace: default    # The namespace to which the ConfigMap belongs.
data:
  key: value    # The configuration information of the storage, expressed in the form of key-value pairs.
immutable: false    # Whether to set ConfigMap to be immutable, false means mutable.

    In the upper right corner of the configuration, you can copy YAML, reset YAML, or view YAML changes.

  5. Click Create.

Viewing ConfigMaps

  1. In the workload cluster list, click the display name of the target workload cluster to enter the Overview page of the workload cluster.

  2. In the sidebar, click Configuration > ConfigMap to view all ConfigMap Info of the workload cluster in the list. You can quickly filter based on one or more namespaces.

    Parameter Description

    Namespace The namespace to which the ConfigMap belongs.
    Data The configuration information of the ConfigMap, displaying the key value in the key-value pair.
