DescribeClusterNodePools API Reference - ACK Serverless - Alibaba Cloud - Container Service for Kubernetes

Queries all node pools in a cluster.

Operation description

When removing nodes, perform standardized operations through this API or the Container Service console. Do not manually remove nodes by using kubectl delete node.
Do not directly release nodes, remove instances, or allow nodes to be passively released due to subscription instance expires in the ECS or ESS console (or through related APIs). In these cases, nodes are directly stopped and automatically removed from the Container Service console.
If the node pool has a desired node count configured, the node pool automatically scales out other instances based on the corresponding configuration to maintain the node count at the desired number.
Removing nodes involves Pod migration, which may affect your services. Perform this operation during off-peak hours. Unexpected risks may occur during the operation. Back up relevant data in advance.
When removing nodes, ACK performs a drain operation. Ensure that other nodes in the cluster have sufficient resources to avoid application pods that cannot be scheduled for scheduling to execute.
Check the node affinity rules and scheduling policies of Pods on the nodes to be removed to ensure that Pods are not left unschedulable after node removal.

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.

If the specified private pool capacity is unavailable, the instance fails to launch. `None`: none mode. The instance does not use private pool capacity.	Open
