Multiple Azure VM base images with the same name - azure

Question

When i use a script to create a VM in Azure and select as the base image "Windows 10, Pro Version 1903" I get the following error: "Found more than 1 image with name 'Windows 10 Pro, Version 1903'. Please pick one from ['Windows 10 Pro, Version 1903', 'Windows 10 Pro, Version 1903']"
If I create a VM from the portal there are two base images with exactly the same name.
az lab vm create --resource-group MyTestRG --lab-name MyTestLab --name 'MyScriptVM' --image "Windows 10 Pro, Version 1903" --image-type gallery --size 'Standard_B2s' --admin-username '****' --admin-password '****'
How are you supposed to use that base image if you can't tell it exactly which one to use?

Answer 1

When you filter the image via CLI command: az lab gallery-image list --lab-name mytestlab --resource-group myrg --query "[?name == 'Windows 10 Pro, Version 1903']", you will find the similar image reference except for the SKU.
However, there is no SKU parameter for Azure CLI az lab vm create. As a workaround, you could create a VM with DevTest Labs using Azure PowerShell.
The sample PowerShell script:
[CmdletBinding()]
Param(
[Parameter(Mandatory = $false)] $SubscriptionId,
[Parameter(Mandatory = $true)] $LabResourceGroup,
[Parameter(Mandatory = $true)] $LabName,
[Parameter(Mandatory = $true)] $NewVmName,
[Parameter(Mandatory = $true)] $UserName,
[Parameter(Mandatory = $true)] $Password
)
pushd $PSScriptRoot
try {
if ($SubscriptionId -eq $null) {
$SubscriptionId = (Get-AzContext).Subscription.SubscriptionId
}
$API_VERSION = '2016-05-15'
$lab = Get-AzResource -ResourceId "/subscriptions/$SubscriptionId/resourceGroups/$LabResourceGroup/providers/Microsoft.DevTestLab/labs/$LabName"
if ($lab -eq $null) {
throw "Unable to find lab $LabName resource group $LabResourceGroup in subscription $SubscriptionId."
}
#For this example, we are getting the first allowed subnet in the first virtual network
# for the lab.
#If a specific virtual network is needed use | to find it.
#ie $virtualNetwork = #(Get-AzResource -ResourceType 'Microsoft.DevTestLab/labs/virtualnetworks' -ResourceName $LabName -ResourceGroupName $lab.ResourceGroupName -ApiVersion $API_VERSION) | Where-Object Name -EQ "SpecificVNetName"
$virtualNetwork = #(Get-AzResource -ResourceType 'Microsoft.DevTestLab/labs/virtualnetworks' -ResourceName $LabName -ResourceGroupName $lab.ResourceGroupName -ApiVersion $API_VERSION)[0]
$labSubnetName = $virtualNetwork.properties.allowedSubnets[0].labSubnetName
#Prepare all the properties needed for the createEnvironment
# call used to create the new VM.
# The properties will be slightly different depending on the base of the vm
# (a marketplace image, custom image or formula).
# The setup of the virtual network to be used may also affect the properties.
# This sample includes the properties to add an additional disk under dataDiskParameters
$parameters = #{
"name" = $NewVmName;
"location" = $lab.Location;
"properties" = #{
"labVirtualNetworkId" = $virtualNetwork.ResourceId;
"labSubnetName" = $labSubnetName;
"notes" = "Windows Server 2016 Datacenter";
"osType" = "windows"
"expirationDate" = "2019-12-01"
"galleryImageReference" = #{
"offer" = "WindowsServer";
"publisher" = "MicrosoftWindowsServer";
"sku" = "2016-Datacenter";
"osType" = "Windows";
"version" = "latest"
};
"size" = "Standard_DS2_v2";
"userName" = $UserName;
"password" = $Password;
"disallowPublicIpAddress" = $true;
"dataDiskParameters" = #(#{
"attachNewDataDiskOptions" = #{
"diskName" = "adddatadisk"
"diskSizeGiB" = "1023"
"diskType" = "Standard"
}
"hostCaching" = "ReadWrite"
})
}
}
#The following line is the same as invoking
# https://azure.github.io/projects/apis/#!/Labs/Labs_CreateEnvironment rest api
Invoke-AzResourceAction -ResourceId $lab.ResourceId -Action 'createEnvironment' -Parameters $parameters -ApiVersion $API_VERSION -Force -Verbose
}
finally {
popd
}
The following command provides an example of running the script saved in a file name: Create-LabVirtualMachine.ps1.
PS> .\Create-LabVirtualMachine.ps1 -ResourceGroupName 'MyLabResourceGroup' -LabName 'MyLab' -userName 'AdminUser' -password 'Password1!' -VMName 'MyLabVM'
