【问题描述】：

我是使用 AWS EBS 和 ECS 的新手，所以如果我提出一个对其他人来说可能很明显的问题，请原谅我。问题：

我在同一个 AWS 云区域中配置了 EBS 和 ECS。我已经推送了我的容器，并且可以在 ECS 中看到图像。 EBS 环境已使用指向 ECS 的Dockerrun.aws.json 构建。在构建 EBS 期间，我收到以下错误：

2020/11/02 20:50:25.858567 [INFO] authenticate with ECR if the image is in an ECR repo
2020/11/02 20:50:25.858582 [INFO] Running command /bin/sh -c aws ecr get-login --no-include-email --registry-ids 731178912345 --region eu-west-1
2020/11/02 20:50:28.355911 [ERROR] An error occurred during execution of command [app-deploy] - [Docker Specific Build Application]. Stop running the command. Error: failed to authenticate with ECR for registry 731178912XXX in eu-west-1: Command /bin/sh -c aws ecr get-login --no-include-email --registry-ids 731178912XXX --region eu-west-1 failed with error exit status 255. Stderr:
An error occurred (AccessDeniedException) when calling the GetAuthorizationToken operation: User: arn:aws:sts::731178912XXX:assumed-role/aws-elasticbeanstalk-ec2-role/i-0bff9b5324348ea71 is not authorized to perform: ecr:GetAuthorizationToken on resource: *

我在某处读到该身份会自动传入以处理身份验证。我找不到任何有关如何解决该问题的指示。也许有人可以帮助我？

添加所讨论的权限后，我得到了这些：

【参考方案1】：

您的aws-elasticbeanstalk-ec2-role 实例角色无权执行ecr:GetAuthorizationToken。

您可以通过将inline policy 添加到aws-elasticbeanstalk-ec2-role 角色来解决此问题：

    "Version": "2012-10-17",
    "Statement": [
        
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "ecr:GetAuthorizationToken",
            "Resource": "*"
        
    ]

请注意，在此之后可能需要更多权限。你可以用同样的方法添加它们。

【讨论】：

感谢您的回复。我究竟会在哪里添加这个？在Dockerrun.aws.json 或其他地方？

@spekulatius 转到 IAM 控制台 -> 角色并搜索 aws-elasticbeanstalk-ec2-role。在那里你可以选择Add inline policy。

这使它向前移动了一点：我添加了权限并重建了环境。它仍然无法提取容器映像 - 这次出现不同的错误消息。关于@Marcin可能是什么原因的任何想法？

@spekulatius 正如我在答案中所写，您可能需要添加更多权限。这次：ecr:BatchGetImage。不知道需要多少。只需随时添加即可。

谢谢你，Marcin，查看日志，我发现又缺少一个权限。添加后它也起作用了！感谢您的帮助！
