Use the UpgradeClusterNodepool API to upgrade Kubernetes, OS, or runtime versions of a node pool - Container Service for Kubernetes - Alibaba Cloud - Container Service for Kubernetes

Upgrades the kubelet version (which should match the control plane version), operating system version, or container runtime version of a specified cluster node pool.

Operation description

Upgrades the Kubernetes version, operating system version, or container runtime version of nodes in a specified cluster node pool. After you call the UpgradeClusterNodepool operation, the API returns a task_id for the upgrade task. You can manage the task by calling the following task API operations:

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.

Path Parameters

Parameter	Type	Required	Description	Example
ClusterId	string	Yes	The cluster ID.	c106f377e16f34eb1808d6b9362c9****
NodepoolId	string	Yes	The node pool ID.	np31da1b38983f4511b490fc62108a****

Request parameters

Parameter	Type	Required	Description	Example
body	object	No	The request parameters.
image_id	string	No	The system image ID of the node.	aliyun_3_x64_20G_container_optimized_20241226.vhd
runtime_version	string	No	The runtime version of the node. You can call DescribeKubernetesVersionMetadata to obtain the runtime version information from the runtime field.	1.6.36
kubernetes_version	string	No	The Kubernetes version of the node. You can call DescribeKubernetesVersionMetadata to obtain the current cluster version information from the `KubernetesVersion` field.	1.32.1-aliyun.1
runtime_type	string	No	The runtime type. You can call DescribeKubernetesVersionMetadata to obtain the runtime information from the runtime field.	containerd
use_replace	boolean	No	Specifies whether to use system cloud disk replacement for the upgrade. Valid values: true: Uses system cloud disk replacement to upgrade the node pool. ACK reinitializes the nodes based on the current node pool configurations, such as the logon method, labels, taints, operating system image, and runtime version. false: Does not use system cloud disk replacement. Default value: false.	false
rolling_policy	object	No	The rolling update configuration.
pause_policy	string	No	The automatic pause policy during node upgrades. Valid values: FirstBatch: pauses after the first batch is completed. EveryBatch: pauses after each batch is completed. NotPause: does not pause.	NotPause
batch_interval	integer	No	The interval between batches during the upgrade. This parameter takes effect only when the pause policy is set to `NotPause`. Valid values: [5,120]. Unit: minutes. You can set this parameter to 0 to specify no interval between batches.	5
max_parallelism	integer	No	The maximum number of nodes that can be upgraded in parallel per batch. Nodes in the node pool are upgraded in batches. Valid values: [1,10]. Default value: 10.	2
node_names	array	No	The list of nodes to upgrade. If this parameter is not specified, all nodes in the node pool are upgraded.
	string	No	The node name, which serves as the node identifier within the cluster.	cn-beijing.10.180.xx.xx
ignore_warning_check	boolean	No
