CloudWatch Canary 的必需角色和权限

要查看 Canary 详细信息和 Canary 运行的结果，您必须以附加了 CloudWatchSyntheticsFullAccess 或 CloudWatchSyntheticsReadOnlyAccess 的 IAM 用户身份登录。要在控制台中读取所有 Synthetics 数据，您还需要 AmazonS3ReadOnlyAccess 和 CloudWatchReadOnlyAccess 策略。要查看 Canary 使用的源代码，您还需要 AWSLambdaReadOnlyAccess 策略。

要创建 Canary，您必须以具有 CloudWatchSyntheticsFullAccess 策略或类似权限集的 IAM 用户身份登录。要为 Canary 创建 IAM 角色，您还需要以下内联策略语句： 

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "iam:CreateRole",
                "iam:CreatePolicy",
                "iam:AttachRolePolicy"
            ],
            "Resource": [
                "arn:aws:iam::*:role/service-role/CloudWatchSyntheticsRole*",
                "arn:aws:iam::*:policy/service-role/CloudWatchSyntheticsPolicy*"
            ]
        }
    ]
}
重要

通过向用户授予 iam:CreateRole、iam:CreatePolicy 和 iam:AttachRolePolicy 权限，用户将获得对 AWS 账户的完全管理访问权限。例如，具有这些权限的用户可以创建一个对所有资源具有完全权限的策略，并将该策略附加到任何角色。请谨慎地为相关人员授予这些权限。

有关附加策略和向用户授予权限的信息，请参阅更改 IAM 用户的权限和为用户或角色嵌入内联策略。
