Configure ConfigMaps and Secrets for Workloads

Workloads can read runtime configuration through ConfigMaps and Secrets. Configuration objects and the workloads that reference them must be in the same namespace.

​

Select a Configuration Object

First, select objects based on whether the configuration content is sensitive, to avoid mistakenly storing credentials in a ConfigMap.

​

Using ConfigMap

​

Create ConfigMap

1. Log in to the GPU Cloud console and go to the Clusters page.
2. Click the target cluster name to go to the cluster workspace.
3. In the left navigation pane, click Configure.
4. Switch to the ConfigMap tab and click Create.
5. Enter the name, namespace, and configuration details. The following YAML creates a ConfigMap that includes the runtime mode and log level. Modify it as needed for the workload.
   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: app-config
     namespace: default
   data:
     APP_MODE: production
     LOG_LEVEL: info
   
6. Submit the creation. After returning to the ConfigMap tab and confirming that the ConfigMap has been created, reference it in the workload.

​

Modify or Delete a ConfigMap

1. On the ConfigMap tab, filter by namespace or use the search box to locate the target ConfigMap.
2. Perform actions as needed:
   • Check the configuration: Click YAML.
   • Modify the configuration: Click Edit, make the changes, and submit them.
   • Delete the configuration: Click Delete and confirm as prompted.

​

Using Secrets

​

Create Secret

1. On the Clusters page, click the name of the target cluster to open the cluster workspace.
2. In the left navigation pane, click Configure.
3. Switch to the Secret tab and click Create.
4. Enter the name, namespace, Secret type, and Secret content. The following YAML shows the structure of an Opaque Type Secret. Replace the example values with credentials used by your application, and manage the content in a controlled manner.
   apiVersion: v1
   kind: Secret
   metadata:
     name: app-secret
     namespace: default
   type: Opaque
   stringData:
     username: REPLACE_WITH_USERNAME
     password: REPLACE_WITH_PASSWORD
   
5. Submit the creation request, return to the Secret tab, confirm that the Secret has been created, and then reference it in the workload.

​

Modify or Delete a Secret

1. On the Secret tab, filter by namespace or use the search box to locate the target Secret.
2. Perform actions as needed:
   • Check the configuration: Click YAML.
   • Modify the configuration: Click Edit, make the changes, and submit them.
   • Delete the configuration: Click Delete, then confirm as prompted.
