如何配置对 Elastic beanstalk Cloudformation 模板的 ECR 读取权限？

问题描述

我有一个带有多容器 docker CF 模板的弹性 beanstalk，如下所示。我单独将我的图像推送到 ECR。在 Dockerrun.json 中，我将我的图像称为这样的“图像”：“.dkr.ecr.ap-south-1.amazonaws.com/*: 最新”。通过使用这个 CF 模板，我可以创建带有多容器的 ELB。但是在部署我的 Dockerrun.json 时，由于我的图像的权限被拒绝而失败。所以我将 Type: AWS::ECR::Repository 添加到我的云形成中。我的 CF 中已经有 MyInstanceProfile。我尝试通过添加策略来授予对 IAM 的访问权限。但是在部署时，我的 CF 任务出现 Encountered unsupported property MyInstanceRole 错误。那么如何修复这个错误或者是否需要任何其他重构？

解决方法

您有重复 MyInstanceRole 定义和缩进不正确。请修正缩进并删除 MyInstanceRole 的第一个定义。它应该如下所示：
