切换集群子网 - ChangeClusterSubnet

功能介绍

当集群所属子网中IP不足,无法执行扩容等添加节点的操作时,可使用本接口切换子网,切换后,扩容等添加节点场景下将使用新子网绑定新增节点,已有节点不会改变。

同VPC下的子网默认网络联通,请确保新子网与您业务系统的网络连通性。另:开启了自动创建ipv6地址的集群只支持切换到开启了ipv6的新子网。

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,需具备如下身份策略权限。
