azure - 无法访问在Azure中使用DCOS Marathon部署的helloworld应用程序

Question

我已使用 DCOS 和 Marathon Framework 在 Azure 中部署了一个 hello world 应用程序。我正在尝试使用 fqn: 托管该应用程序的端口号来访问该应用程序。我无法打开该应用程序

以下是我使用的json

{
  "id": "/dockercloud-hello-world",
  "cmd": null,
  "cpus": 0.1,
  "mem": 128,
  "disk": 0,
  "instances": 2,
  "acceptedResourceRoles": [
    "*"
  ],
  "container": {
    "type": "DOCKER",
    "volumes": [],
    "docker": {
      "image": "dockercloud/hello-world",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 80,
          "hostPort": 0,
          "servicePort": 10000,
          "protocol": "tcp",
          "labels": {}
        }
      ],
      "privileged": false,
      "parameters": [],
      "forcePullImage": true
    }
  },
  "healthChecks": [
    {
      "gracePeriodSeconds": 10,
      "intervalSeconds": 2,
      "timeoutSeconds": 10,
      "maxConsecutiveFailures": 10,
      "portIndex": 0,
      "path": "/",
      "protocol": "HTTP",
      "ignoreHttp1xx": false
    }
  ],
  "portDefinitions": [
    {
      "port": 10000,
      "protocol": "tcp",
      "name": "default",
      "labels": {}
    }
  ]
}

我已为主 nsg 资源添加 NSG 入站规则我已为主 lb 资源添加了 NAT 规则，允许自定义端口

Answer 1

在您的示例中，主机端口为0，Azure将在随机端口上监听您的服务。您需要打开 NSG 和 lb 上的端口。

我建议你可以指定端口，你可以检查以下示例:

{
  "id": "/dockercloud-hello-world",
  "cmd": null,
  "cpus": 0.1,
  "mem": 32,
  "disk": 0,
  "instances": 1,
  "acceptedResourceRoles": [
    "slave_public"
  ],
  "container": {
    "type": "DOCKER",
    "volumes": [],
    "docker": {
      "image": "dockercloud/hello-world",
      "network": "BRIDGE",
      "portMappings": [
        {
          "containerPort": 80,
          "hostPort": 80,
          "protocol": "tcp",
          "labels": {},
          "name": "test80"
        }
      ],
      "privileged": false,
      "parameters": [],
      "forcePullImage": true
    }
  },
  "healthChecks": [
    {
      "gracePeriodSeconds": 10,
      "intervalSeconds": 2,
      "timeoutSeconds": 10,
      "maxConsecutiveFailures": 10,
      "portIndex": 0,
      "path": "/",
      "protocol": "MESOS_HTTP",
      "ignoreHttp1xx": false
    }
  ],
  "requirePorts": true
}

注意:您应该将 acceptedResourceRoles 设置为 slave_public。有关此的更多信息请查看此 link .
