跨账户访问SSM参数

Question

我按照 AWS 开发者论坛帖子（现已不再可用）中提到的说明进行操作。

政策

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "ssm:GetParametersByPath",
                "ssm:GetParameters",
                "ssm:GetParameter"
            ],
            "Resource": "arn:aws:ssm:eu-central-1:XXXXXXXXXX:parameter/some-root/*"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": "ssm:DescribeParameters",
            "Resource": "*"
        }
    ]
}

我已将策略附加到角色中的目标账户

当我从源帐户获取参数时，它可以工作，但是我无法从目标帐户访问它们。

C:\Users\my-home>aws ssm get-parameters-by-path --path "/some-root/" --profile aws-acc-src
{
    "Parameters": [
        {
            "Name": "/some-root/dev",
            "Type": "SecureString",
            "Value": "AQICAHh5z4qygT6rbxBnR/PmJn811vO30kBJNB+JrB1tdKNBeAEHFLSQDpTMsRMc1l0D8lXYAAAAYTBfBgkqhkiG9w0BBwagUjBQAgEAMEsGCSqGSIb3DQEHATAeBglghkgBZQMEAS4wEQQM+Qmz5FoNcESEXabnAgEQgB6MdOlb545EPN61QqA50w7rH3sghmNWvxsLPPneHEA=",

            "LastModifiedDate": "2020-10-06T16:03:32.637000+03:00",
            "ARN": "arn:aws:ssm:eu-central-1:XXXXXXXX:parameter/some-root/dev"
        }
    ]
}

aws ssm get-parameters-by-path --path "/some-root/" --with-decryption --profile aws-acc-src
{
    "Parameters": [
        {
            "Name": "/some-root/dev",
            "Type": "SecureString",
            "Value": "foo",
            "Version": 1,
            "LastModifiedDate": "2020-10-06T16:03:32.637000+03:00",
            "ARN": "arn:aws:ssm:eu-central-1:XXXXXXXX:parameter/some-root/dev"
        }
    ]
}

aws ssm get-parameters-by-path --path "/some-root/" --with-decryption --profile aws-acc-target
{
    "Parameters": []
}

看起来，参数存储不支持跨帐户访问。或者，您可以使用密钥管理器在不同的 AWS 账户之间共享密钥。
