前面几篇文章介绍过Azure的两种VM的模式，包括ASM和ARM。并且介绍了如何用Azure CLI和PowerShell创建虚拟机。本文将介绍如何采用Json的Template来创建基于ARM的VM。
当然采用Json Template的方式创建虚拟机是几种方式中最好的，这样可以便于批量部署、Json文件可以重用。
ARM的Template的格式采用的是Json的格式。其需要的几个部分如下：
需要定义的有：parameters，variables，resources和outputs。但只有resources是必须的。
由于Template的内容比较复杂，一般都采用复制已有的Template Jason文件修改的方式。
目前，在Github上有大量的Azure ARM Jason Template，可以下载修改使用。
具体的网址在：
https://github.com/Azure/azure-quickstart-templates
比如我们要创建一台CentOS 6.5的Linux虚拟机。在上面的链接中，没有相应的template。我们通过一台Ubuntu的Template进行修改。
首先下载两个Jason文件：
第一个文件是部署文件，第二个文件是参数文件。
我们首先看部署文件：
一、修改parameter中的内容
1 把Ubuntu版本改成CentOS版本：
"ubuntuOSVersion": { "type": "string", "defaultValue": "14.04.2-LTS", "allowedValues": [ "12.04.5-LTS", "14.04.2-LTS", "15.10" ],
改成
"CentOSVersion": { "type": "string", "defaultValue": "6.5", "allowedValues": [ "6.5", "6.6", "7.0", "7.1" ],
2 把metadata的描述更改
"metadata": { "description": "The Ubuntu version for the VM. This will pick a fully patched image of this given Ubuntu version. Allowed values: 12.04.5-LTS, 14.04.2-LTS, 15.10." }
改为：
"metadata": { "description": "The CentOS version for the VM. This will pick a fully patched image of this given CentOS version. Allowed values: 6.5, 6.6, 7.0, 7.1." }
二、修改variables中的内容
原始的变量定义如下：
"variables": { "storageAccountName": "[concat(uniquestring(resourceGroup().id), 'salinuxvm')]", "dataDisk1VhdName": "datadisk1", "imagePublisher": "Canonical", "imageOffer": "UbuntuServer", "OSDiskName": "osdiskforlinuxsimple", "nicName": "myVMNic", "addressPrefix": "10.0.0.0/16", "subnetName": "Subnet", "subnetPrefix": "10.0.0.0/24", "storageAccountType": "Standard_LRS", "publicIPAddressName": "myPublicIP", "publicIPAddressType": "Dynamic", "vmStorageAccountContainerName": "vhds", "vmName": "MyUbuntuVM", "vmSize": "Standard_D1", "virtualNetworkName": "MyVNET", "vnetID": "[resourceId('Microsoft.Network/virtualNetworks',variables('virtualNetworkName'))]", "subnetRef": "[concat(variables('vnetID'),'/subnets/',variables('subnetName'))]", "apiVersion": "2015-06-15" },
更改为：
"variables": { "storageAccountName": "[concat(uniquestring(resourceGroup().id), 'salinuxvm')]", "dataDisk1VhdName": "datadisk1", "imagePublisher": "OpenLogic", "imageOffer": "CentOS", "OSDiskName": "osdiskforlinuxsimple", "nicName": "myVMNic", "addressPrefix": "10.0.0.0/16", "subnetName": "Subnet", "subnetPrefix": "10.0.0.0/24", "storageAccountType": "Standard_LRS", "publicIPAddressName": "myPublicIP", "publicIPAddressType": "Dynamic", "vmStorageAccountContainerName": "vhds", "vmName": "MyCentOSVM", "vmSize": "Standard_A1", "virtualNetworkName": "MyVNET", "vnetID": "[resourceId('Microsoft.Network/virtualNetworks',variables('virtualNetworkName'))]", "subnetRef": "[concat(variables('vnetID'),'/subnets/',variables('subnetName'))]", "apiVersion": "2015-06-15" },
修改完部署文件后，修改参数文件：
参数文件如下：
{ "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#", "contentVersion": "1.0.0.0", "parameters": { "adminUsername": { "value": "azureUser" }, "adminPassword": { "value": "GEN-PASSWORD" }, "dnsLabelPrefix": { "value": "GEN-UNIQUE" }, "ubuntuOSVersion": { "value": "14.04.2-LTS" } } }
更改为：
{ "$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#", "contentVersion": "1.0.0.0", "parameters": { "adminUsername": { "value": "hengwei" }, "adminPassword": { "value": "abc@123456" }, "dnsLabelPrefix": { "value": "hwvm" }, "CentOSVersion": { "value": "6.5" } } }
并把两个文件上传到Github上，链接如下：
https://raw.githubusercontent.com/hengv/Hengwei/Azure/101-simple-linux/azuredeploy.json
https://raw.githubusercontent.com/hengv/Hengwei/Azure/101-simple-linux/azuredeploy.parameters.json
下面可以通过PowerShell命令通过Jason Template创建VM了：
New-AzureRmResourceGroup -Name hw01 -Location chinaeast ResourceGroupName : hw01 Location : chinaeast ProvisioningState : Succeeded Tags : ResourceId : /subscriptions/xxxxxxxx/resourceGroups/hw01
New-AzureRmResourceGroupDeployment -Name hwvm01 -ResourceGroupName hw01 -TemplateUri https://raw.githubusercontent.com/hengv/Hengwei/Azure/101-simple-linux/azuredeploy.json -TemplateParameterUri https://raw.githubusercontent.com/hengv/Hengwei/Azure/101-simple-linux/azuredeploy.parameters.json -Mode Incremental DeploymentName : hwvm01 ResourceGroupName : hw01 ProvisioningState : Succeeded Timestamp : 2016/7/1 14:09:58 Mode : Incremental TemplateLink : Uri : https://raw.githubusercontent.com/hengv/Hengwei/Azure/101-simple-linux/azuredeploy.json ContentVersion : 1.0.0.0 Parameters : Name Type Value =============== ========================= ========== adminUsername String hengwei adminPassword SecureString dnsLabelPrefix String hwvm centOSVersion String 6.5 Outputs : Name Type Value =============== ========================= ========== hostname String hwvm.chinaeast.cloudapp.azure.com sshCommand String ssh hengwei@hwvm.chinaeast.cloudapp.azure.com DeploymentDebugLogLevel :
创建成功。
再通过下面的命令查看：
