Elastic Beanstalk 服务角色
服务角色是 Elastic Beanstalk 在代表您调用其他服务时代入的 IAM 角色。例如，Elastic Beanstalk 在调用 Amazon Elastic Compute Cloud（Amazon EC2）、Elastic Load Balancing 和 Amazon EC2 Auto Scaling API 来收集信息时，将会使用一个服务角色。Elastic Beanstalk 使用的服务角色是您在创建 Elastic Beanstalk 环境时指定的角色。
有两个托管策略附加到服务角色。这些策略提供的权限允许 Elastic Beanstalk 访问创建和管理环境所需的 AWS 资源。一个托管策略提供增强的运行状况监控和工作线程层 Amazon SQS 支持的权限，另一个策略提供托管平台更新所需的其他权限。
此策略授予 Elastic Beanstalk 监控环境运行状况所需的所有权限。它还包括 Amazon SQS 操作，以允许 Elastic Beanstalk 监控工作线程环境的队列活动。

}此策略向 Elastic Beanstalk 授予权限，以代表您更新环境以执行托管平台更新。
服务级别权限分组
此策略根据提供的权限集分为多个语句。
-
ElasticBeanstalkPermissions– 这一组权限用于调用 Elastic Beanstalk 服务操作（Elastic Beanstalk API）。 -
AllowPassRoleToElasticBeanstalkAndDownstreamServices– 这一组权限允许将任何角色传递给 Elastic Beanstalk 及其他下游服务，例如 AWS CloudFormation。 -
ReadOnlyPermissions– 这一组权限用于收集有关运行环境的信息。 -
*OperationPermissions– 采用此命名模式的组用于调用执行平台更新必需的操作。 -
*BroadOperationPermissions– 采用此命名模式的组用于调用执行平台更新必需的操作。它们还包括支持旧环境的广泛权限。 -
*TagResource– 采用这种命名模式的组适用于使用 tag-on-create API 为在 Elastic Beanstalk 环境中创建的资源附加标签的调用。

}您可以使用以下任一方法创建 Elastic Beanstalk 环境。每个部分都描述了该方法如何处理服务角色。
Elastic Beanstalk 控制台
使用 Elastic Beanstalk 控制台创建环境时，Elastic Beanstalk 将提示您创建一个名为 aws-elasticbeanstalk-service-role 的服务角色。当通过 Elastic Beanstalk 创建时，此角色包括一个信任策略，允许 Elastic Beanstalk 代入服务角色。本主题前面描述的两个托管策略也会附加到该角色。
Elastic Beanstalk 命令行界面 (EB CLI)
您可以使用 Elastic Beanstalk 命令行界面（EB CLI）的 eb create 命令创建环境。如果您未通过 --service-role 选项指定服务角色。Elastic Beanstalk 将创建相同的默认服务角色 aws-elasticbeanstalk-service-role。如果默认服务角色已存在，Elastic Beanstalk 会将其用于新环境。当通过 Elastic Beanstalk 创建时，此角色包括一个信任策略，允许 Elastic Beanstalk 代入服务角色。本主题前面描述的两个托管策略也会附加到该角色。
Elastic Beanstalk API
您可以使用 Elastic Beanstalk API 的 CreateEnvironment 操作创建环境。如果您未指定服务角色，Elastic Beanstalk 将创建一个监控服务相关角色。这是独特类型的服务角色，由 Elastic Beanstalk 预定义，它具有服务代表您调用其他 AWS 服务所需的所有权限。服务相关角色与您的账户关联。Elastic Beanstalk 仅会创建此角色一次，然后在创建其他环境时重复使用此角色。您也可以使用 IAM 提前为账户创建此监控服务相关角色。在您的账户具有监控服务相关角色时，您可以通过 Elastic Beanstalk 控制台、Elastic Beanstalk API 或 EB CLI 使用该角色创建环境。有关如何将服务相关角色与 Elastic Beanstalk 环境结合使用的说明，请参阅将服务相关角色用于 Elastic Beanstalk。
有关服务角色的更多信息，请参阅 管理 Elastic Beanstalk 服务角色。
