amazon-web-services - 无法通过 `docker pull` 从单独的帐户访问 ECR 存储库

Question

我试图允许一个 AWS 账户(下面称为“第二个”)在另一个 AWS 账户(下面称为“第一个”)的 ECR 存储库中提取图像。

我正在关注这些文件:

https://docs.aws.amazon.com/AmazonECR/latest/userguide/RepositoryPolicyExamples.html (设置权限)

https://aws.amazon.com/premiumsupport/knowledge-center/secondary-account-access-ecr/ (获取 token )

我已将以下权限添加到 ECR 存储库:

{
  "Version": "2008-10-17",
  "Statement": [
    {
      "Sid": "AllowCrossAccountPull",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::<second>:root"
      },
      "Action": [
        "ecr:BatchCheckLayerAvailability",
        "ecr:BatchGetImage",
        "ecr:GetDownloadUrlForLayer"
      ]
    }
  ]
}

然后我运行这个命令: eval "$(aws ecr get-login --no-include-email --region us-east-1 --profile second --registry-ids <second> <first>)"
我得到了这个结果:

WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /Users/libby/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

我把店改成了 config.json暂时只是为了确保我可以看到身份验证已按预期添加到文件中，它是:

{
        "auths": {
                "<second>.dkr.ecr.us-east-1.amazonaws.com": {
                        "auth": "<super long token>"
                },
                "<first>.dkr.ecr.us-east-1.amazonaws.com": {
                        "auth": "<super long token>"
                }
        },
        "HttpHeaders": {
                "User-Agent": "Docker-Client/18.09.0 (darwin)"
        },
        "stackOrchestrator": "swarm"
}

最后我跑了: docker pull <first>.dkr.ecr.us-east-1.amazonaws.com/<repo>:<tag>并得到这个结果:

Error response from daemon: pull access denied for <first>.dkr.ecr.us-east-1.amazonaws.com/<repo>, repository does not exist or may require 'docker login'

我已经三重检查了所有帐号是否正确， repo 肯定在那里。如果我使用相同的 get-login 登录，我就可以拉它。命令但 --profile first .

我不知道还要尝试什么才能拉出这张图片!

更改 Principal在对 "AWS": "arn:aws:iam::<second>:user/<user>" 的 ECR 权限中没有任何区别。

Answer 1

我想通了——“第二个”账户中的 IAM 用户附加了一个限制其 ECR 访问的策略。该政策是:

    {
        "Sid": "ECRAccess",
        "Effect": "Allow",
        "Action": "ecr:*",
        "Resource": "arn:aws:ecr:us-east-1:<second>:repository/<unrelated-repo>"
    }

因此，即使“第一个”帐户中的 ECR 存储库具有允许用户访问的权限，用户自己的帐户也将其访问限制为单个不相关的存储库。

当我使用第一个帐户的存储库 ARN 添加另一个部分时:

    {
        "Sid": "FirstAccountECRAccess",
        "Effect": "Allow",
        "Action": "ecr:*",
        "Resource": "arn:aws:ecr:us-east-1:<first>:repository/<repo>"
    }

然后 docker pull工作!
