amazon-web-services - 如何在 ElasticBeanstalk Cloudformation 模板中为 IAM 用户配置对 ECR 的访问权限？

Question

我有如下 Elastic Beanstalk 模板。我正在使用多容器 docker 。所以我单独将我的图像推送到ECR。在 Dockerrun.json 中，我像这样引用我的图像 "image": "*****.dkr.ecr.ap-south-1.amazonaws.com/*** ***:最新”。通过使用这个 CF 模板，我可以创建具有多容器的 ELB。但是在部署我的 Dockerrun.json 时，由于我的镜像的权限被拒绝，它失败了。因此，我将 Type: AWS::ECR::Repository 添加到我的云结构中。我的 CF 中已经有 MyInstanceProfile。这里我想给MyInstanceProfile添加ECR权限。那么如何为ElasticbeanStalk云组建模板分配ECR权限呢？

Answer 1

通常您会指定角色的 ARN:

            Principal:
              AWS: !GetAtt MyInstanceRole.Arn

更新:

  MyInstanceRole:
    Type: AWS::IAM::Role
    Properties:
      AssumeRolePolicyDocument:
        Version: 2012-10-17
        Statement:
          - Effect: Allow
            Principal:
              Service:
                - ec2.amazonaws.com
            Action:
              - sts:AssumeRole
