You can call the ModifyClusterNodePool operation to modify node configurations in a cluster node pool, such as kubelet and node rotation configurations. This operation modifies configurations in batches and restarts the kubelet, which may affect node and workload operations. Perform this operation during off-peak hours.
Operation description
-
Each user is limited to 10 calls per second.
-
Modifying a node pool is an asynchronous operation. After you call the API, the operation takes 10 to 20 minutes to complete. During this time, you can call the DescribeClustersV1 operation to check the cluster status.
