使用 CLI 从快照创建虚拟机Create a virtual machine from a snapshot with CLI

此脚本从 OS 磁盘的快照创建虚拟机。This script creates a virtual machine from a snapshot of an OS disk.

若要运行此示例,请安装最新版本的 Azure CLITo run this sample, install the latest version of the Azure CLI. 若要开始,请运行 az login 以创建与 Azure 的连接。To start, run az login to create a connection with Azure.

适用于 Azure CLI 的示例是针对 bash shell 编写的。Samples for the Azure CLI are written for the bash shell. 若要在 Windows PowerShell 或命令提示符中运行此示例,可能需要更改脚本的元素。To run this sample in Windows PowerShell or Command Prompt, you may need to change elements of the script.

如果没有 Azure 订阅,可在开始前创建一个试用帐户If you don't have an Azure subscription, create a trial account before you begin.

示例脚本Sample script

#Provide the subscription Id of the subscription where you want to create Managed Disks
subscriptionId=dd80b94e-0463-4a65-8d04-c94f403879dc

#Provide the name of your resource group
resourceGroupName=myResourceGroupName

#Provide the name of the snapshot that will be used to create Managed Disks
snapshotName=mySnapshotName

#Provide the name of the Managed Disk
osDiskName=myOSDiskName

#Provide the size of the disks in GB. It should be greater than the VHD file size.
diskSize=128

#Provide the storage type for Managed Disk. Premium_LRS or Standard_LRS.
storageType=Premium_LRS

#Provide the OS type
osType=linux

#Provide the name of the virtual machine
virtualMachineName=myVirtualMachineName

#Set the context to the subscription Id where Managed Disk will be created
az account set --subscription $subscriptionId

#Get the snapshot Id 
snapshotId=$(az snapshot show --name $snapshotName --resource-group $resourceGroupName --query [id] -o tsv)

#Create a new Managed Disks using the snapshot Id
az disk create --resource-group $resourceGroupName --name $osDiskName --sku $storageType --size-gb $diskSize --source $snapshotId 

#Create VM by attaching created managed disks as OS
az vm create --name $virtualMachineName --resource-group $resourceGroupName --attach-os-disk $osDiskName --os-type $osType

清理部署Clean up deployment

运行以下命令来删除资源组、VM 和所有相关资源。Run the following command to remove the resource group, VM, and all related resources.

az group delete --name myResourceGroup

脚本说明Script explanation

此脚本使用以下命令创建托管磁盘、虚拟机和所有相关资源。This script uses the following commands to create a managed disk, virtual machine, and all related resources. 表中的每条命令均链接到特定于命令的文档。Each command in the table links to command specific documentation.

CommandCommand 说明Notes
az snapshot showaz snapshot show 使用快照名称和资源组名称获取快照。Gets snapshot using snapshot name and resource group name. 返回对象的 ID 属性用于创建托管磁盘。Id property of the returned object is used to create a managed disk.
az disk createaz disk create 使用快照 ID、磁盘名称、存储类型和大小从快照创建托管磁盘Creates managed disks from a snapshot using snapshot Id, disk name, storage type, and size
