如何使我的集装箱港口可在集装箱外使用？ ECS-AWS

Question

我正在尝试让Docker容器在ECS中运行。我创建了一个基本的express应用，该应用正在侦听端口3000。这是我的AWS设置。我有一个ECS集群，其中只有一项任务。

我的AWS存储库中有一个容器，该容器在此集群中作为任务运行。

{
  "executionRoleArn": "arn:aws:iam::035892600013:role/ecsTaskExecutionRole",
  "containerDefinitions": [

        }
      },
      "entryPoint": [],
      "portMappings": [
        {
          "hostPort": 3000,
          "protocol": "tcp",
          "containerPort": 3000
        }

  ],
  "networkMode": "awsvpc",

}

从JSON中，您可以看到该容器正在侦听端口3000，但是我无法通过url:3000访问该应用程序。它只是旋转。我还想念什么？

我尝试卷曲应用程序，但一无所获。卷曲只是坐在等待响应。我确实确认应用程序正在容器中运行。这是日志：
