Question

好像我在Terraform部署中收到了格式错误的策略，并且在查看该策略时未发现任何问题，所有Principals似乎都在适当的位置，看起来没有什么< em>与众不同。有人可以找出为什么该政策被认为格式不正确吗？

这是正在抛出的TF输出

module.s3-bucket.aws_s3_bucket_policy.bucket_policy: Creating...
  bucket: "" => "the_s3_bucket"
  policy: "" => "{\n  \"Version\":\"2012-10-17\",\n    \"Statement\":[{\n      \"Principal\": \"*\",\n      \"Action\":[\n        \"s3:GetBucketLocation\",\n        \"s3:ListAllMyBuckets\"\n      ],\n        \"Resource\":[\n          \"arn:aws:s3:::*\"\n      ],\n    \"Effect\":\"Allow\"\n  }, {\n    \"Principal\": \"*\",\n    \"Action\":[\n      \"s3:ListBucket\",\n      \"s3:ListBucketMultipartUploads\"\n    ],\n    \"Resource\":[\n      \"arn:aws:s3:::the_s3_bucket\"\n    ],\n    \"Effect\":\"Allow\"\n    }, {\n      \"Principal\": \"*\",\n    \"Action\":[\n      \"s3:GetObject\",\n      \"s3:AbortMultipartUpload\",\n      \"s3:ListMultipartUploadParts\",\n      \"s3:DeleteObject\",\n      \"s3:PutObject\",\n      \"s3:GetObjectAcl\",\n      \"s3:PutObjectAcl\"\n    ],\n    \"Resource\":[\n      \"arn:aws:s3:::the_s3_bucket/*\"\n    ],\n    \"Effect\":\"Allow\"\n  }]\n}\n"

（非详细）错误：

Error applying plan:

这是其中包含的精美印刷品

        "s3:GetBucketLocation",
        "s3:ListAllMyBuckets"
      ],
        "Resource":[
          "arn:aws:s3:::*"
      ],
    "Effect":"Allow"
  }, {
    "Principal": "*",
    "Action":[
      "s3:ListBucket",
      "s3:ListBucketMultipartUploads"
    ],
    "Resource":[
      "arn:aws:s3:::the_s3_bucket"
    ],
    "Effect":"Allow"
    }, {
      "Principal": "*",
    "Action":[

      "s3:GetObjectAcl",
      "s3:PutObjectAcl"
    ],
    "Resource":[
      "arn:aws:s3:::the_s3_bucket/*"
    ],
    "Effect":"Allow"
  }]
}

更新

显然，这与Principal字段有关，在通过AWS控制台运行此错误之后，我收到了错误消息

This policy contains the following error: Has prohibited field Principal For more information about the IAM policy grammar, see AWS IAM Policies

s3:ListAllMyBuckets权限不能应用于S3存储桶策略，而是IAM策略权限。您还必须在存储桶策略中直接指定该策略所附加的存储桶，而不是对存储桶使用"Resource": ["*"]或其他通配符。

IAM策略和S3存储桶策略密切相关并且重叠很多，但是您应该将它们视为有时可能需要的进一步控制级别。不幸的是，S3权限模型非常混乱，并且具有多层添加访问控制的功能，从bucket ACLs和对象ACL（包括完全可配置的ACL和罐头ACL）到bucket policies以及直接的IAM permissions附加到IAM用户或角色。

大多数时候，最好使用canned ACLs，然后使用IAM用户策略来控制谁可以执行ACL不允许的其他操作。 User Guide中对此有进一步的解释。
