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，然后它就被杀死了。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。此处配置为没有目标组或负载均衡器：

因此，从我所见，服务正在启动，gunicorn（用于 Python Web 应用程序的服务器）正在启动，侦听端口 8000，我已映射等等。我还在我的应用程序中公开了 /health/ 端点，以允许简单和轻量级的健康检查（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 服务 Web 任务 7982151a4a904a82b077fc48410dd672 容器健康检查失败。
我做错了什么？
答案 0 :(得分：0)
你能做 2 个与健康检查相关的检查并写下你的发现吗？
