Automatic plan execution reports permissions

The following is a sample policy to attach if you configure automatic report generation for a Region switch plan. This policy includes permissions to write reports to Amazon S3, access CloudWatch alarm data, and retrieve child plan information for parent plans.

  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:PutObject",
      "Resource": "arn:aws:s3:::your-bucket-name/*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "cloudwatch:DescribeAlarms",
        "cloudwatch:DescribeAlarmHistory"
      ],
      "Resource": [
        "arn:aws:cloudwatch:us-east-1:123456789012:alarm:app-health-primary"
        "arn:aws:cloudwatch:us-west-2:123456789012:alarm:app-health-secondary"
      ],
    },
    {
      "Effect": "Allow",
      "Action": [
        "arc-region-switch:GetPlanExecution",
        "arc-region-switch:ListPlanExecutionEvents"
      ],
      "Resource": [
        "arn:aws:arc-region-switch:us-east-1:123456789012:plan/child-plan-1/abcde1",
        "arn:aws:arc-region-switch:us-west-2:123456789012:plan/child-plan-2/fghij2"
      ],
    }
  ]
}

Note: If you configure a customer managed AWS KMS key for Amazon S3 bucket encryption, you must also add kms:GenerateDataKey and kms:Encrypt permissions for the key.
