AWS System Manager GetParameters 权限被隐式拒绝

问题描述

我正在尝试为 eks 设置 eksctl 但它抛出 "Error: unable to determine AMI to use: error getting AMI from SSM Parameter Store: AccessDeniedException: User: arn:aws:iam:::user/cnc is not authorized to perform: ssm:GetParameter on resource: arn:aws:ssm:us-east-1::parameter/aws/service/eks/optimized-ami/1.18/amazon-linux-2/recommended/image_id".

我使用的 IAM 权限策略是

    "Version": "2012-10-17","Statement": [
        {
            "Effect": "Allow","Action": [
                "ssm:DescribeParameters"
            ],"Resource": "*"
        },{
            "Effect": "Allow","Action": [
                "ssm:GetParameters","ssm:GetParametersByPath"
            ],"Resource": "arn:aws:ssm:::parameter/*"
        }
    ]

我也尝试使用策略模拟来检查权限，它给了我“隐式拒绝（无匹配语句）”

解决方法

我认为您可能还需要授权“ssm:GetParameter”操作。

我遇到了同样的问题。我解决它的方法是将区域添加到 ssm 资源。并且还添加了一个 ssm:GetParameter 像这样：

"Version": "2012-10-17","Statement": [
    {
        "Effect": "Allow","Action":[
            "ssm:DescribeParameters"
        ],"Resource": "*"
    },{
        "Effect": "Allow","Action":[
            "ssm:GetParameters","ssm:GetParameter","ssm:GetParametersByPath"
        ],"Resource": "arn:aws:ssm:ca-central-1::parameter/*"
    }
]

如果您注意到我添加了区域 ca-central-1，您应该将其更改为您当前的区域。
