如何从 codebuild buildspec 获取 S3 对象？（拒绝访问）

Question

我有一个带有 CodeBuild 阶段的 CodePipeline 管道

这是我的构建规范：

{
  "version": "0.2",
  "phases": {
    "build": {
      "commands": [
        "echo \"Hello, CodeBuild!\"",
        "echo \"ca marche\" > test.txt",
        "mkdir site-content",
        "aws s3 sync s3://my-super-bucket-name site-content",
        "ls - al"
      ]
    }
  },
  "artifacts": {
    "files": [
      "test.txt"
    ]
  }
}

构建项目服务角色是使用默认的 cdk 生成策略定义的，加上这个：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": "s3:*",
            "Resource": [
                "arn:aws:s3:::my-super-bucket-name",
                "arn:aws:s3:::my-super-bucket-name/* "
            ],
            "Effect": "Allow"
        }
    ]
}

并且 codebuild.amazonaws.com 是角色的可信实体

在存储桶方面，我有这个存储桶策略：

{
    "Version": "2012-10-17",
    "Id": "PolicyXXXXXXXXXXXXX",
    "Statement": [
        {
            "Sid": "StmtYYYYYYYYYYYYY",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::12345678910:user/a-user-for-another-process"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::my-super-bucket-name"
        }
    ]
}

但是构建项目失败了：

[Container] 2021/02/03 09:57:43 Running command aws s3 sync s3://my-super-bucket-name site-content
download failed: s3://my-super-bucket-name/test.txt to site-content/test.txt An error occurred (AccessDenied) when calling the GetObject operation: Access Denied
Completed 4 Bytes/13.7 KiB (0 Bytes/s) with 4 file(s) remaining

求助！

编辑：我只是将此声明添加到存储桶策略中：

        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::XXXXXXXXXXXXX:role/my-role"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::my-super-bucket-name"
        }

但是我有同样的错误:(

编辑 2：傻我！它是：

"Resource": "arn:aws:s3:::my-super-bucket-name*"

现在可以了！

您应该修改存储桶策略以向您的代码构建角色授予显式访问权限，因为如果没有存储桶策略附加到存储桶，那么首先会根据存储桶策略检查权限，然后按照您尝试的方式进行操作.
