Modifies the configuration of a node pool, such as the kubelet configuration and node rolling update configuration. After you modify the node pool configuration, nodes are batch updated and the kubelet on each node is restarted. This may adversely affect the nodes and workloads. We recommend that you perform this operation during off-peak hours.

Operation description

Note Container Service for Kubernetes (ACK) allows you to modify the kubelet configuration of nodes in a node pool. After you modify the kubelet configuration, the new configuration immediately takes effect on existing nodes in the node pool and is automatically applied to newly added nodes.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.
