Azure CLI Samples for Azure DevTest Labs

This article includes sample bash scripts built for Azure CLI for Azure DevTest Labs.

Script	Description
Create and verify a virtual machine (VM)	Creates a Windows VM with minimal configuration.
Start a VM	Starts a VM.
Stop and delete a VM	Stops and deletes a VM.

Prerequisites

To run this sample, install the latest version of the Azure CLI. To start, run az login to create a connection with Azure.

Samples for the Azure CLI are written for the bash shell. To run this sample in Windows PowerShell or Command Prompt, you may need to change elements of the script.

If you don't have an Azure subscription, create an Azure free account before you begin.

All of these scripts have the following prerequisite:

• A lab. The script requires you to have an existing lab.

Create and verify availability of a VM

This Azure CLI script creates a virtual machine in a lab. The VM created based on a marketplace image with SSH authentication. The script then verifies that the VM is available for use.

resourceGroupName='<Resource group in which lab exists>'
location='<Location in which the lab exists>'
labName="<Name of the lab>"
vmName="<Name for the VM>"
vmImageName="<Name of the image. For example: Ubuntu Server 16.04 LTS>"
vmSize="<Size of the image. For example: Standard_DS1_v2>"

# Create a resource group
az group create \
    --name $resourceGroupName \
    --location $location

# Create a VM from a marketplace image with ssh authentication
az lab vm create 
    --lab-name $labName 
    --resource-group $resourceGroupName
    --name $vmName 
    --image $vmImageName
    --image-type gallery 
    --size $vmSize
    --authentication-type  ssh 
    --generate-ssh-keys 
    --ip-configuration public

# Verify that the VM is available
az lab vm show 
    --lab-name sampleLabName 
    --name sampleVMName 
    --resource-group sampleResourceGroup 
    --expand 'properties($expand=ComputeVm,NetworkInterface)' 
    --query '{status: computeVm.statuses[0].displayStatus, fqdn: fqdn, ipAddress: networkInterface.publicIpAddress}'

This script uses the following commands:

Command	Notes
az group create	Creates a resource group in which all resources are stored.
az lab vm create	Creates a VM in a lab.
az lab vm show	Displays the status of the VM in a lab.

Start a VM

This Azure CLI script starts a virtual machine in a lab.

resourceGroupName='<Resource group in which lab exists>'
labName="<Name of the lab>"
vmName="<Name for the VM>"

# Start the VM
az lab vm start 
    --lab-name $labName
    --name $vmName 
    --resource-group $resourceGroupName

This script uses the following commands:

Command	Notes
az lab vm start	Starts a VM in a lab. This operation can take a while to complete.

Stop and delete a VM

This Azure CLI script stops and deletes a virtual machine in a lab.

Caution

Deleting VMs and labs is permanent, and cannot be undone.

resourceGroupName='<Resource group in which lab exists>'
labName="<Name of the lab>"
vmName="<Name for the VM>"

# Stop the VM
az lab vm stop 
    --lab-name $labName
    --name $vmName 
    --resource-group $resourceGroupName

# Delete the VM
az lab vm delete 
    --lab-name $labName 
    --name $vmName
    --resource-group $resourceGroupName

This script uses the following commands:

Command	Notes
az lab vm stop	Stops a VM in a lab. This operation can take a while to complete.
az lab vm delete	Deletes a VM in a lab. This operation can take a while to complete.

Clean up deployment

Run the following command to remove the resource group, VM, and all related resources.

Caution

Deleting the resource group for the lab is permanent, and cannot be undone. This will remove ALL resources under the group and can not be restored.

az group delete --name $resourceGroupName
