删除服务关联角色

重要

删除AliyunServiceRoleForEMRonACK后，您将无法使用EMR on ACK控制台的相关功能。

使用RAM管理员登录RAM控制台。
在左侧导航栏，选择身份管理 > 角色。
在角色页面的搜索框中，输入AliyunServiceRoleForEMROnACK进行搜索。
单击目标角色操作列的删除角色。
在弹出的对话框中输入角色名称，单击删除角色。
- 如果当前账号下没有正在使用的EMR on ACK实例，则可以直接删除AliyunServiceRoleForEMROnACK。
- 如果当前账号下存在正在使用的EMR on ACK实例，则必须首先删除该实例，才能继续删除AliyunServiceRoleForEMROnACK，否则将提示删除失败。

常见问题

Q：为什么我的 RAM 用户无法自动创建服务关联角色？

A：因为您的 RAM 用户缺少创建服务关联角色的权限。您需要联系 RAM 管理员，为该 RAM 用户授予 ram:CreateServiceLinkedRole 权限。具体操作，请参见管理RAM角色的权限。

推荐的最小化授权策略如下，请将 阿里云账号ID 替换为您实际的阿里云账号 ID。
