轮转节点证书 - RotateNodeCert

功能介绍

该API用于在指定集群下轮转节点证书。作为集群证书轮转操作的补偿机制:当通过配套的集群证书轮转接口执行轮转时,若部分节点证书轮转失败,可通过调用本接口进行重试。

集群管理的URL格式为:https://Endpoint/uri。其中uri为资源路径,也即API访问的路径。

接口约束

  • 节点所在的集群,必须已经轮转过证书;

  • 待执行证书轮转的节点必须状态为“运行中”。

调用方法

请参见如何调用API

授权信息

账号具备所有API的调用权限,如果使用账号下的IAM用户调用当前API,该IAM用户需具备调用API所需的权限。

  • 如果使用角色与策略授权,具体权限要求请参见权限和授权项
  • 如果使用身份策略授权,当前API调用无需身份策略权限。
