AWS ECS/EC2 任务部署失败

Question

我正在尝试使用 ECS 将一个小型 React 应用程序部署到 EC2 实例，但我不断收到错误消息

Resource handler returned message: "Error occurred during operation 'ECS Deployment Circuit Breaker was triggered'." (RequestToken: xxx-xxx-xxx-xxx, HandlerErrorCode: GeneralServiceException)

我尝试手动将应用程序部署到 EC2 实例（使用

docker run -p 80:3000 my-app

），效果很好，所以我很确定应用程序和 Dockerfile 都正常。 Docker 镜像托管在 ECR 中。

我认为这很可能是我的任务定义的问题。看起来像这样：

我也有同样的问题。不知道如何以及在哪里找到解决方案。 问题是失败的原因不可见。我知道应该有日志或比错误名称更多的东西，它不提供任何信息。
