You can create and manage native Kubernetes resources through the console. Distributed cloud applications support the management of Kubernetes objects, such as Deployment, Configmap, Service, and third-party CRDs, among others.
For a description of Kubernetes objects, please refer to Kubernetes Objects. You are allowed to create, delete, modify, and view these resources. Moreover, you can bind Subscription to K8s application resources, and according to these strategies, deploy the resources to multiple target clusters.
Directions
Creating K8s Application Resources
1. Log in to the TDCC console, and navigate to the Distributed Application Management > Application Management page.
2. In the new resource Tag page on the left side, click Create to create a resource. For an introduction to the various types of resources, please refer to Kubernetes Objects.
3. For configuring the parameters of the new resource at the bottom of the resource creation page, you need to set a Subscription for this resource. You can choose Creating Subscription, Existing Subscription, or Do Not Associate with Subscription:
Do Not Associate with Subscription: This resource will not be distributed, but you can designate a Subscription for it later.
Creating Subscription: Follow the prompts to add the clusters where you wish to distribute the resource, or configure a LabelSelector Tag selector.
Existing Subscription: Select a previously created Subscription.
4. Click Create to complete the resource creation.
Viewing K8s Application Resources
1. Log in to the TDCC console, and navigate to the Distributed Application Management > Application Management page.
2. The list page displays K8s resource objects and their associated Subscriptions, supporting filtering by Subscription.
Name: K8s resource name.
Namespace: The namespace where the resource is located.
Subscription: The Subscription associated with the resource, supports editing the associated Subscription.
Operations: Supports operations on this resource, including viewing and editing YAML, deletion, etc.
3. Click the name link to enter the details page for this object:
Subscription: The Subscription associated with the resource.
Topology Diagram: Graphically displays the Subscription associated with the object, target clusters, differentiated configurations, and other related status information.
Basic Information: Displays detailed information about the K8s application object.
4. Click the Instance Management tab to view the instances running on the target cluster:
Instance Name: The name of the K8s resource distributed to the target cluster. Clicking the name will redirect you to the details page of the application.
Cluster: The name of the target cluster where the instance is located. Clicking the cluster name will redirect you to its management page.
Subscription: The instance is managed and distributed according to this Subscription.
Namespace: The namespace where the instance is located.
Status: The status information of the instance.
Updating Localization/Globalization: Supports creating, updating, and deleting Localization/Globalization. For the configuration description of the Localization/Globalization, please see: Localization/Globalization.
5. Click the YAML tab to view the YAML configuration of the resource object.
Modifying Associated Subscriptions
1. Log in to the TDCC Console. Navigate to Distributed Application Management > Application Management page.
2. Click the modify icon in the Subscription column. In the pop-up dialog, assign a different Subscription to the object.
Note
When a Cancel operation is performed on a Subscription and saved, the instances of the application distributed by that strategy will be synchronously deleted.
Modifying K8s application resources
1. Log in to the TDCC Console. Navigate to Distributed Application Management > Application Management page.
2. Click Editing YAML to edit the configuration of the object in the pop-up dialog.
3. click Done, the modified configuration will automatically update to all target clusters according to the Subscription.
Configuring Localization/Globalization
1. To configure a K8s object for a specific cluster separately, click to enter the Details > Instance List Tag page. Find the K8s object instance you want to modify, click Creating Localization/Globalization configuration strategy. For an introduction to Localization/Globalization, see Localization/Globalization.
2. To modify or cancel a differentiated configuration, click to enter the Details > Instance Management Tag page. On the specified distribution instance, click Updating Localization/Globalization or Deleting Localization/Globalization to perform the specified action.
Delete K8s Application Resources
1. Log in to the TDCC Console. Navigate to Distributed Application Management > Application Management page.
2. Select the object to be deleted. Confirm that the object has no associated Subscription, then click Delete to proceed with deletion.
Note
If you delete a K8s resource object associated with a Subscription, a dialog box will prompt you until all associated Subscriptions are disassociated and can be deleted.
