节点迁移到自定义节点池 - MigrateToNodePool

功能介绍

该API用于将节点迁移到自定义节点池,仅default节点池下节点支持迁移。迁移过程节点无重置无重启,原节点密码将保留。

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

  • 仅支持迁入与节点池相同VPC、子网、企业项目、云服务器组、规格、可用区、资源预留、容器引擎、操作系统的节点。

  • 仅支持迁入DefaultPool节点池里状态为运行中的节点。

  • 节点迁入后,将同步节点池资源标签、K8S标签、K8S污点配置,冲突时,使用节点池配置覆盖。

  • 节点迁入后,将采用节点池安全组替换节点原来的安全组。

  • 节点迁入后,将清除节点的纳管标记,节点池缩容节点时将同步删除云服务器。

  • 迁入后保留节点原有的登录方式。

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。
