通过 TaskCat 拒绝访问 S3答案

【问题标题】：Access denied to S3 via TaskCat通过 TaskCat 拒绝访问 S3
【发布时间】：2021-02-02 20:44:33
【问题描述】：

我想使用 Taskcat 进行部署。一切都很好，除了（一如既往）权限。我为我的模板创建了一个存储桶，它在配置文件中被引用。我打电话给taskcat test run，在模板上传到我的存储桶后，我收到一个错误，stack creation 由于 S3 error: Access Denied 而失败。

由于我能够通过 TaskCat 上传模板，因此我的帐户拥有正确的权限。是否需要添加存储桶权限，Cloudformation 才能访问该存储桶？

错误代码：

【解决方案1】：

当您通过控制台启动 CloudFormation Stack 时，您登录时使用的用户，其凭据将用于所有操作。

当您说可以上传到 S3 存储桶时，并不直接转换为您也可以下载对象。

所以请检查您的configured credentials，如果您有必要的操作权限。
