如何将一个 IAM 用户限制为只有 1 个存储桶？

Question

我有一个存储桶 myapp，我想将新创建的 IAM 用户（没有组策略）限制到该存储桶。

但我不知道该怎么做。

我试过这个：

{
    "Statement": [
        {
            "Effect":"Allow",
            "Action": [ 
                "s3:ListBucket"
            ],
            "Resource":"arn:aws:s3:::myapp/*"
        }
    ]
}

然而，当我使用该用户登录 IAM 控制台时，我看到：

我该如何实现？

这是我现在为我的用户使用的政策：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:GetBucketLocation",
                "s3:ListAllMyBuckets"
            ],
            "Resource": "arn:aws:s3:::*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:ListBucket"
            ],
            "Resource": [
                "arn:aws:s3:::myapp"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:DeleteObject"
            ],
            "Resource": [
                "arn:aws:s3:::myapp/*"
            ]
        }
    ]
}

但是，当我上传图片时，出现此错误：

Excon::Errors::Forbidden at /jobs

excon.error.response
  :body          => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>0FF1D4848595DCFB</RequestId><HostId>+RrQvNFwV2hAcYPK3ZJJYzy5uiA7Aag0oc1Gpp3hENJ9lzJz453j8qJeLbdQ8jN4cc3ViRJ1lEg=</HostId></Error>"
  :cookies       => [
  ]
  :headers       => {
    "Connection"       => "close"
    "Content-Type"     => "application/xml"
    "Date"             => "Sat, 25 Jun 2016 18:54:24 GMT"
    "Server"           => "AmazonS3"
    "x-amz-id-2"       => "+R3ViRJ1lEg="
    "x-amz-request-id" => "0FF1DCFB"
  }
  :host          => "s3.amazonaws.com"
  :local_address => "192.168.1.102"
  :local_port    => 23456
  :path          => "/logos/company/logo/48/amped-logo.png"
  :port          => 443
  :reason_phrase => "Forbidden"
  :remote_ip     => "xx.xx.xxx.xxx"
  :status        => 403
  :status_line   => "HTTP/1.1 403 Forbidden\r\n"

这是我的 CORS 规则：

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>http://localhost:3000</AllowedOrigin>
        <AllowedMethod>HEAD</AllowedMethod>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>PUT</AllowedMethod>
        <AllowedMethod>POST</AllowedMethod>
        <AllowedMethod>DELETE</AllowedMethod>
        <ExposeHeader>ETag</ExposeHeader>
        <AllowedHeader>*</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

我终于解决了这个问题，如您所见：AWS S3 403 Forbidden Error on newly created IAM inline policy for a new IAM user

您需要添加 getbucketlocation 和 listAllbuckets 权限以允许用户控制台访问。

{
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:GetBucketLocation",
        "s3:ListAllMyBuckets"
      ],
      "Resource": "arn:aws:s3:::*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:ListBucket"
      ],
      "Resource": "arn:aws:s3:::myapp/*"
    }
  ]
}
