Uso de una red virtual existente con Azure Managed Applications

  • Artículo

En este artículo se muestra cómo definir una aplicación administrada de Azure que se integra con una red virtual existente en la suscripción del cliente. La aplicación administrada permite al cliente decidir si quiere crear una nueva red virtual o usar una existente. La red virtual existente puede estar fuera del grupo de recursos administrado.

Plantilla principal

En primer lugar, vamos a echar un vistazo al archivo mainTemplate.json. Se muestra toda la plantilla para implementar una máquina virtual y sus recursos asociados. Luego, revisaremos los elementos de la plantilla que están relacionadas con el uso de una red virtual existente.

}

Observe que la red virtual se implementa de forma condicional. El cliente pasa un valor de parámetro que indica si se va a crear una red virtual nueva o se va a usar una existente. Si el cliente selecciona una red virtual nueva, se implementa el recurso. De lo contrario, el recurso se omite durante la implementación.

{
  "condition": "[equals(parameters('virtualNetworkNewOrExisting'),'new')]",
  "type": "Microsoft.Network/virtualNetworks",
  "apiVersion": "2021-02-01",
  "name": "[parameters('virtualNetworkName')]",
  "location": "[parameters('location')]",
  "properties": {
    "addressSpace": {
      "addressPrefixes": [
        "[parameters('virtualNetworkAddressPrefix')]"
      ]
    },
    "subnets": [
      {
        "name": "[parameters('subnetName')]",
        "properties": {
          "addressPrefix": "[parameters('subnetAddressPrefix')]"
        }
      }
    ]
  }
},

La variable del identificador de red virtual tiene dos propiedades. Una propiedad devuelve el identificador de recurso cuando se implementa una nueva red virtual. La otra devuelve el identificador de recurso cuando se usa una red virtual existente. El identificador de recurso de la red virtual existente incluye el nombre del grupo de recursos que contiene la red virtual.

El identificador de subred se construye a partir del valor del identificador de red virtual. Usa el valor que coincide con la selección de los clientes.

"variables": {
  "storageAccountName": "[concat(uniquestring(resourceGroup().id), 'sawinvm')]",
  "publicIPAddressName": "[concat(uniqueString(resourceGroup().id),'IP')]",
  "vmName": "[parameters('vmName')]",
  "nicName": "[concat(parameters('vmName'),'Nic')]",
  "vnetId": {
    "new": "[resourceId('Microsoft.Network/virtualNetworks',parameters('virtualNetworkName'))]",
    "existing": "[resourceId(parameters('virtualNetworkResourceGroup'),'Microsoft.Network/virtualNetworks',parameters('virtualNetworkName'))]"
  },
  "subnetId": "[concat(variables('vnetId')[parameters('virtualNetworkNewOrExisting')],'/subnets/',parameters('subnetName'))]",
  "publicIPAddressType": "Dynamic"
},

La interfaz de red se establece en la variable del identificador de subred.

El archivo incluye un elemento de red virtual.

  "label": {
    "virtualNetwork": "Virtual Network",
    "subnets": "Subnets"
  },
  "defaultValue": {

        "minAddressCount": 8,
        "requireContiguousAddresses": true
      }
    }
  }
},

Ese elemento permite al cliente seleccionar una red virtual nueva o existente.

Red virtual nueva o existente

En las salidas, se incluye un valor que indica si el cliente ha seleccionado una red virtual nueva o existente. También hay un valor de identidad administrada.

Nota:

El valor de salida de la identidad administrada debe tener el nombre managedIdentity.
