如何在 AWS ECS 上运行非 Web docker 容器

Question

我所拥有的是 Python 脚本，它们侦听 SQS 并处理从这些脚本接收到的消息。这些被 dockerized 并上传到 ECR。要求是使用 EC2 在 ECS 上运行此 docker，并根据来自 sqs 的消息数量进行扩展/扩展。

问题是我无法运行定义的任务，我认为它的原因是没有设置健康检查，所以我将它设置为 CMD_SHELL, ps aux | grep "Python" || exit 1 ，但没有人可以帮助我。也可以在 ECS 上运行 Non-Web 应用程序。

如果有人有任何文件，请指点我。

我在这里发布我的容器定义

任何关于是否可以在 ECS 上运行非服务器容器的建议都会有很大的帮助，或者有人已经这样做了，请告诉我应该是什么健康检查

运行 ECS 任务不需要“he​​althCheck”。我建议您检查任务的停止状态并在“python-extract”CloudWatch 日志组中查看任务的日志。
