Application Auto Scaling 基于身份的策略示例

默认情况下，您中的全新用户 Amazon Web Services 账户 无权执行任何操作。IAM 管理员必须创建并分配 IAM policy，以便为 IAM 身份（例如用户或角色）授予执行 Application Auto Scaling API 操作的权限。

要了解如何使用以下示例 JSON 策略文档创建 IAM policy，请参阅《IAM 用户指南》中的在 JSON 选项卡上创建策略。

Application Auto Scaling API 操作所需的权限

以下策略为调用 Application Auto Scaling API 时的常见使用案例授予权限。编写基于身份的策略时，请参阅本节。每个策略授予执行全部或部分 Application Auto Scaling API 操作的权限。您还需要确保最终用户拥有目标服务的权限，以及 CloudWatch （有关详细信息，请参阅下一节）。

以下基于身份的策略授予执行全部 Application Auto Scaling API 操作的权限。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
              "application-autoscaling:*"
            ],
            "Resource": "*"
        }
    ]
}

以下基于身份的策略授予执行配置扩展策略而非计划操作所需的全部 Application Auto Scaling API 操作的权限。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
              "application-autoscaling:RegisterScalableTarget",
              "application-autoscaling:DescribeScalableTargets",
              "application-autoscaling:DeregisterScalableTarget",
              "application-autoscaling:PutScalingPolicy",
              "application-autoscaling:DescribeScalingPolicies",
              "application-autoscaling:DescribeScalingActivities",
              "application-autoscaling:DeleteScalingPolicy"
            ],
            "Resource": "*"
        }
    ]
}

以下基于身份的策略授予执行配置计划操作而非扩展策略所需的全部 Application Auto Scaling API 操作的权限。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
              "application-autoscaling:RegisterScalableTarget",
              "application-autoscaling:DescribeScalableTargets",
              "application-autoscaling:DeregisterScalableTarget",
              "application-autoscaling:PutScheduledAction",
              "application-autoscaling:DescribeScheduledActions",
              "application-autoscaling:DescribeScalingActivities",
              "application-autoscaling:DeleteScheduledAction"
            ],
            "Resource": "*"
        }
    ]
}

在中工作的权限 Amazon Web Services Management Console

没有独立的 Application Auto Scaling 控制台。与 Application Auto Scaling 集成的大多数服务都具有专用于帮助您通过控制台配置扩缩的功能。

在大多数情况下，每项服务都提供 Amazon 托管（预定义）IAM 策略，这些策略定义了对其控制台的访问权限，其中包括对 Application Auto Scaling API 操作的权限。有关详细信息，请参阅要使用其控制台的服务的文档。

您还可以创建自己的自定义 IAM policy，为用户授予在 Amazon Web Services Management Console中查看和处理特定 Application Auto Scaling API 操作的精细权限。您可以使用前面部分中的示例策略；但是，它们是为使用 Amazon CLI 或 SDK 发出的请求而设计的。控制台使用其他 API 操作实现其功能，因此这些策略可能不会按预期方式起作用。例如，要配置分步缩放，用户可能需要额外的权限才能创建和管理 CloudWatch 警报。

提示

为帮助您了解在控制台中执行任务所需的相应 API 操作，您可以使用 Amazon CloudTrail等服务。有关更多信息，请参阅《Amazon CloudTrail 用户指南》。

以下基于身份的策略授予为竞价型实例集配置扩展策略的权限。除了竞价型实例集的 IAM 权限之外，从 Amazon EC2 控制台访问实例集扩展设置的控制台用户必须具有使用支持动态扩展的服务的适当权限。

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "application-autoscaling:*",
                "ec2:DescribeSpotFleetRequests",
                "ec2:ModifySpotFleetRequest",
                "cloudwatch:DeleteAlarms",
                "cloudwatch:DescribeAlarmHistory",
                "cloudwatch:DescribeAlarms",
                "cloudwatch:DescribeAlarmsForMetric",
                "cloudwatch:GetMetricStatistics",
                "cloudwatch:ListMetrics",
                "cloudwatch:PutMetricAlarm",
                "cloudwatch:DisableAlarmActions",
                "cloudwatch:EnableAlarmActions",
                "sns:CreateTopic",
                "sns:Subscribe",
                "sns:Get*",
                "sns:List*"
            ],
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": "iam:CreateServiceLinkedRole",
            "Resource": "arn:aws:iam::*:role/aws-service-role/ec2.application-autoscaling.amazonaws.com/AWSServiceRoleForApplicationAutoScaling_EC2SpotFleetRequest",
            "Condition": {
                "StringLike": {
                    "iam:AWSServiceName":"ec2.application-autoscaling.amazonaws.com"
                }
            }
        }
    ]
}

该策略允许控制台用户在 Amazon EC2 控制台中查看和修改扩展策略，并在控制 CloudWatch 台中创建和管理 CloudWatch 警报。

您可以调整 API 操作以限制用户访问权限。例如，将 application-autoscaling:Describe* 替换为 application-autoscaling:* 意味着用户具有只读访问权限。

您也可以根据需要调整 CloudWatch 权限，以限制用户对 CloudWatch功能的访问权限。有关更多信息，请参阅 Amazon CloudWatch 用户指南中的使用 CloudWatch 控制台所需的权限。
