Synchronizing Node Configurations in a Node Pool

Function

This API is used to synchronize the configurations of existing nodes in a node pool.

The URL for cluster management is in the format of https://Endpoint/uri, where uri specifies the resource path for API access.

Calling Method

For details, see Calling APIs.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.

If you are using identity policy-based authorization, the following identity policy-based permissions are required.
