首先，我使用服务器环境：
- 服务器：django + nginx + uwsgi
- 云：docker + AWS ECS
- 日志记录：AWS CloudWatch 日志服务 + 瞭望塔第三方应用
这是项目代码

问题
我正在使用 django watchtower 第三方应用程序来使用 AWS Cloudwatch 日志服务。如果我将日志处理程序设置为瞭望塔并将 docker 映像上传到 ECS 服务并运行任务，它仍然会返回 500 错误。
500错误如果你检查日志

创建任务定义时，将任务 IAM 角色分配给管理员。
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "*",
"Resource": "*"
}
]
}
但是，容器仍然不与凭据对话。
如果我将日志处理程序更改为默认（控制台），nginx 服务器将正常工作。如果我在本地运行 docker conatiner docker run -v $ HOME / .aws: /root/.aws --rm -it -p 9090: 80 image_name，nginx 将正常工作，并且日志记录将在 Cloudwatch 日志服务中正常工作。
仅在 ECS 环境下认证失败。
除了 IAM 角色，我还需要做其他设置吗？
