Question

我正在构建一个azure模板（https://github.com/kevinday/azure-quickstart-templates/blob/master/augur-on-ubuntu/azuredeploy.json），它将在Ubuntu VM中运行nodejs应用程序。

npm start

augur-ui@2.0.0 start /root/augur
http-server ./build -c-1 -p $PORT

Starting up http-server, serving ./build
Available on:
http://127.0.0.1:true
http://10.0.0.4:true
Hit CTRL-C to stop the server

我想将http流量公开给我配置的dns名称http://dnsname.eastus.cloudapp.azure.com。

我已经看到了在门户网站中建议配置和端点的文档，但我不再看到此选项。有人能指出我正确的方向来修改我的模板，以便正确配置这个端点吗？

您需要在网络安全组中创建入站规则，以允许端口80上的流量。

{
  "apiVersion": "[variables('apiVersion')]",
  "type": "Microsoft.Network/networkSecurityGroups",
  "name": "[variables('networkSecurityGroupName')]",
  "location": "[resourceGroup().location]",
  "properties": {
    "securityRules": [
      {
        "name": "httpRule",
        "properties": {
          "description": "httpRule",
          "protocol": "Tcp",
          "sourcePortRange": "*",
          "destinationPortRange": "80",
          "sourceAddressPrefix": "*",
          "destinationAddressPrefix": "*",
          "access": "Allow",
          "priority": 110,
          "direction": "Inbound"
        }
      }
    ]
  }
}

此处提供了包含NSG和入站规则的完整模板示例：https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/101-security-group-create/azuredeploy.json

众所周知，您可以尝试创建[Win32Exception (0x80004005): The wait operation timed out] [SqlException (0x80131904): Connection Timeout Expired.

请参阅文档How to create NSGs using a template以了解如何使用ARM进行此操作。
