resourceAttach怎么使用

`resourceAttach` 是一个用于在 Azure Resource Manager (ARM) 模板中添加附加资源的函数。它可以将一个或多个资源添加到现有的资源组中，并为这些资源创建依赖关系。

以下是一个示例，演示如何在 ARM 模板中使用 `resourceAttach` 函数：

{
    "parameters": {
        "storageAccountName": {
            "type": "string",
            "metadata": {
                "description": "Storage account name."
            }
        },
        "location": {
            "type": "string",
            "metadata": {
                "description": "Location for all resources."
            }
        }
    },
    "resources": [
        {
            "name": "[parameters('storageAccountName')]",
            "type": "Microsoft.Storage/storageAccounts",
            "apiVersion": "2021-04-01",
            "location": "[parameters('location')]",
            "sku": {
                "name": "Standard_LRS"
            },
            "kind": "StorageV2"
        }
    ],
    "outputs": {
        "storageAccountId": {
            "type": "string",
            "value": "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName'))]"
        }
    }
}

在此 ARM 模板中，我们创建了一个存储帐户资源。如果我们想在此资源组中添加其他资源（例如，虚拟机、网络接口等），我们可以使用 `resourceAttach` 函数。

以下是一个示例，演示如何使用 `resourceAttach` 函数将虚拟机添加到现有的 ARM 模板中：

{
    "parameters": {
        "storageAccountName": {
            "type": "string",
            "metadata": {
                "description": "Storage account name."
            }
        },
        "vmName": {
            "type": "string",
            "metadata": {
                "description": "Virtual machine name."
            }
        },
        "vmSize": {
            "type": "string",
            "metadata": {
                "description": "Virtual machine size."
            }
        },
        "location": {
            "type": "string",
            "metadata": {
                "description": "Location for all resources."
            }
        }
    },
    "resources": [
        {
            "name": "[parameters('storageAccountName')]",
            "type": "Microsoft.Storage/storageAccounts",
            "apiVersion": "2021-04-01",
            "location": "[parameters('location')]",
            "sku": {
                "name": "Standard_LRS"
            },
            "kind": "StorageV2"
        },
        {
            "name": "[parameters('vmName')]",
            "type": "Microsoft.Compute/virtualMachines",
            "apiVersion": "2021-03-01",
            "location": "[parameters('location')]",
            "dependsOn": [
                "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName'))]"
            ],
            "properties": {
                "hardwareProfile": {
                    "vmSize": "[parameters('vmSize')]"
                },
                "storageProfile": {
                    "imageReference": {
                        "publisher": "Canonical",
                        "offer": "UbuntuServer",
                        "sku": "16.04-LTS",
                        "version": "latest"
                    },
                    "osDisk": {
                        "createOption": "FromImage"
                    }
                },
                "networkProfile": {
                    "networkInterfaces": [
                        {
                            "id": "[resourceId('Microsoft.Network/networkInterfaces', concat(parameters('vmName'), '-nic'))]"
                        }
                    ]
                }
            }
        }
    ],
    "outputs": {
        "storageAccountId": {
            "type": "string",
            "value": "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName'))]"
        },
        "vmId": {
            "type": "string",
            "value": "[resourceId('Microsoft.Compute/virtualMachines', parameters('vmName'))]"
        }
    }
}

在此 ARM 模板中，我们添加了一个虚拟机资源，并使用 `resourceAttach` 函数来创建虚拟机的网络接口资源。注意，虚拟机的 `networkProfile` 属性引用了网络接口的资源 ID，这意味着虚拟机是依赖于网络接口的。

{
    "name": "[concat(parameters('vmName'), '-nic')]",
    "type": "Microsoft.Network/networkInterfaces",
    "apiVersion": "2021-02-01",
    "location": "[parameters('location')]",
    "dependsOn": [
        "[resourceId('Microsoft.Storage/storageAccounts', parameters('storageAccountName'))]"
    ],
    "properties": {
        "ipConfigurations": [
            {
                "name": "ipconfig1",
                "properties": {
                    "subnet": {
                        "id": "[resourceId('Microsoft.Network/virtualNetworks/subnets', 'myVnet', 'default')]"
                    },
                    "privateIPAllocationMethod": "Dynamic"
                }
            }
        ]
    }
}

此示例展示了如何使用 `resourceAttach` 函数将网络接口资源添加到现有的 ARM 模板中。注意，网络接口的 `ipConfigurations` 属性引用了虚拟网络的子网资源 ID。

希望这些示例能够帮助你了解如何使用 `resourceAttach` 函数。
