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：
https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/101-vm-simple-linux/azuredeploy.json
https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/101-vm-simple-linux/azuredeploy.parameters.json
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：
