【问题描述】：
我有一个要在 AWS 上使用 Fargate 启动的任务定义。现在没有任何负载平衡和东西。我只想运行任务。定义如下：

但是，当我想启动它时，它会启动大约 1.5 分钟，然后就被杀死了。我怀疑这与健康检查有关。
在某些时候它只是收到一个终止信号并停止。这里没有配置目标组或负载均衡器：

所以从我看到的情况来看，服务正在启动，gunicorn（python web 应用程序的服务器）正在启动，监听端口 8000，我已经映射等等。我还在我的应用程序中公开了/health/ 端点，以便进行简单且轻量级的健康检查（它只返回 200 秒）。然而在服务控制台中，我不断收到：
3a52c067-63bd-4d58-a092-a69d29380962 2021-07-10 11:46:08 +0200 service web task 7982151a4a904a82b077fc48410dd672 容器健康检查失败。
我做错了什么？
【问题讨论】：
-
如果没有 ALB，那么检查您的健康状况是什么？
-
这件事似乎是 Fargate 负责的。
-
您是否将任务作为 ecs 服务的一部分运行？
-
任务定义中有一个健康检查，如果我理解正确，它只有在它是服务的一部分时才起作用
-
是的。使用 Fargate。
