在阿里云Elasticsearch（简称ES）中，通过PrivateLink的终端节点实现Kibana或服务的私网访问、管理Beats采集器和时，需要通过RAM角色扮演（服务关联角色）的方式访问其他云服务的资源。在您执行上述特定操作时，如果未创建过对应的服务关联角色，系统将自动为您创建。本文将对ES的服务关联角色进行介绍，并介绍如何删除服务关联角色。
应用场景
服务关联角色的应用场景如下：
AliyunServiceRoleForElasticsearch：需要在用户VPC中访问云原生管控的ES节点或Kibana时。
AliyunServiceRoleForElasticsearchCollector：创建和管理Beats采集器时。
关于服务关联角色的详细信息，请参见服务关联角色。
ES服务关联角色介绍
AliyunServiceRoleForElasticsearch
当您需要在VPC内访问云原生管控ES实例的节点或Kibana时，如果不存在具有执行任务权限的角色，ES将自动创建对应角色（服务关联角色），并为该角色授予相应的权限。ES通过扮演该角色调用私网连接PrivateLink或ECS网络配置相关的API，为您创建如终端节点等资源并完成相关配置，以满足您Kibana私网访问等需求。该角色的相关说明如下：

AliyunServiceRoleForElasticsearchCollector
创建和管理Beats采集器时，如果不存在具有执行任务权限的角色，ES将自动创建对应角色（服务关联角色），并为该角色授予相应的权限。ES通过扮演该角色即可调用OpenAPI，完成Beats采集器在ECS或Kubernetes版ACK目标机器上的数据采集任务。该角色的相关说明如下：

执行服务关联角色操作所需的用户权限：ram:CreateServiceLinkedRole
删除服务关联角色
删除服务角色前，需要先删除依赖这个服务角色的所有任务或设备。删除服务关联角色的具体操作，请参见删除服务关联角色。
常见问题
Q：为什么我的RAM用户无法创建ES的服务关联角色？
A：阿里云账号或拥有CreateServiceLinkedRole权限的RAM用户，才能创建或删除服务关联角色。RAM用户无法自动创建服务关联角色时，需要手动为其添加以下权限策略。具体操作，请参见为RAM用户授权。
{
"Version": "1",
"Statement": [
{
"Action": "elasticsearch:InitializeOperationRole",
"Resource": "acs:ram:*:133071096032****:role/*",
"Effect": "Allow"
},
{
"Action": "ram:CreateServiceLinkedRole",
"Resource": "acs:ram:*:133071096032****:role/*",
"Effect": "Allow",
"Condition": {
"StringEquals": {
"ram:ServiceName": [
"XXX.aliyuncs.com"
]
}
}
}
]
}Resource中的值
133071096032****需要替换为您的阿里云账号ID。阿里云账号ID的获取方法：鼠标移至控制台右上角的用户头像上，即可查看到账号ID。
ram:ServiceName中的值
XXX.aliyuncs.com需要替换为对应服务关联角色的ram:ServiceName。AliyunServiceRoleForElasticsearch（开启ES实例的Kibana私网访问功能）：elasticsearch.aliyuncs.com
AliyunServiceRoleForElasticsearchCollector（创建和管理Beats采集器）：collector.elasticsearch.aliyuncs.com
