ConfigMaps

Creating a ConfigMap

1. Log in to the CCI 2.0 console.
2. In the navigation pane, choose Configuration Center.
3. Select a namespace and click the ConfigMaps tab.
4. Click Create from YAML in the upper left corner and edit the YAML file. For details about the YAML file, see YAML format.
   

   CCI 2.0 supports both JSON and YAML, and the file size cannot exceed 1 MiB.

5. Click OK.

Using a ConfigMap

After a ConfigMap is created, you can mount it to a container as a storage volume during pod creation. For example, mount a ConfigMap named system-preset-aeskey to a container and set the storage volume name to volume1.
