amazon-web-services - 使用 AWS CLI 创建 CloudFront 失效时访问被拒绝

Question

我正在使用 AWS CLI 在脚本中创建 CloudFront 分配:

aws configure set preview.cloudfront true
aws cloudfront create-invalidation --distribution-id ABCD1234 --paths '/*'

我用这个语句设置了一个策略:

{
    "Sid": "xxx",
    "Effect": "Allow",
    "Action": [
        "cloudfront:CreateInvalidation"
    ],
    "Resource": [
        "arn:aws:cloudfront::xxx:distribution/ABCD1234"
    ]
}

该策略附加到运行命令的用户。但是，我仍然收到此错误:

A client error (AccessDenied) occurred when calling the CreateInvalidation operation: User: arn:aws:iam::xxx:user/yyy is not authorized to perform: cloudfront:CreateInvalidation

问题是 CloudFront 无法使用指定资源的策略。 “扩大”政策修复了错误。

This support thread状态:

CloudFront does not support Resource-Level permissions for IAM.

它也被埋在 documentation for CloudFront :

Operation:             POST Invalidation (CreateInvalidation)
Required Permissions:  cloudfront:CreateInvalidation
Resources:             *

这意味着政策需要是:

{
    "Sid": "xxx",
    "Effect": "Allow",
    "Action": [
        "cloudfront:CreateInvalidation"
    ],
    "Resource": [
        "*"  <-- must be a wildcard
    ]
}
