Delete ENS Cluster Node Pool Using DeleteClusterNodePool API - ENS - Alibaba Cloud - ENS

You can call the DeleteClusterNodePool operation to delete a node pool that you no longer need. When you delete a node pool, all pods on its nodes are also deleted. This action may trigger descheduling. If the pods cannot be rescheduled, your services may be affected. Before you delete the node pool, ensure that the cluster has sufficient resources for rescheduling.

Operation description

Each user is limited to 10 calls per second.
Cluster creation is an asynchronous operation. After the API call is successful, wait 10 to 20 minutes for the cluster to initialize. During this time, you can call the DescribeClustersV1 operation to check the cluster status. After the cluster is created, you can call the DescribeClusterUserKubeconfig operation to obtain the cluster's kubeconfig file.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
