I have image in compute gallery and I want to update that image to scaleset , what is the way to do it, I want that image to be used by scale set, Please suggest how we can achive that

Hi @Varma You would use the az vmss update command to change the image reference in your scale set model. For example: az vmss update \ --resource-group myResourceGroup \ --name myScaleSet \ --set virtualMachineProfile.storageProfile.imageReference.id="/subscriptions/<subscriptionId>/resourceGroups/<resourceGroupName>/providers/Microsoft.Compute/galleries/<galleryName>/images/<imageName>/versions/<imageVersion>" Just make sure the image you want to use is already created and available in your Compute Gallery.

Hi @Varma

For example:

az vmss update \ --resource-group myResourceGroup \ --name myScaleSet \ --set virtualMachineProfile.storageProfile.imageReference.id="/subscriptions/<subscriptionId>/resourceGroups/<resourceGroupName>/providers/Microsoft.Compute/galleries/<galleryName>/images/<imageName>/versions/<imageVersion>"

Just make sure the image you want to use is already created and available in your Compute Gallery.

Hi Jackson

I have not created scaleset yet,

I am going to create uniform scaleset with already available image in the gallery

In that case what is the exact command I should use?

Here’s the command to create a VMSS using an image from your Compute Gallery

Reference: https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/quick-create-cli

az vmss create \ --resource-group <yourResourceGroup> \ --name <yourScaleSetName> \ --image "/subscriptions/<subscriptionId>/resourceGroups/<resourceGroupName>/providers/Microsoft.Compute/galleries/<galleryName>/images/<imageName>/versions/<imageVersion>" \ --upgrade-policy-mode automatic \ --admin-username <adminUsername> \ --generate-ssh-keys \ --instance-count <numberOfInstances>

Hi Varma the error message indicates that VM Scale Set creation process failed because the specified image from your Compute Gallery wasn't found in the eastus2

"In region eastus2, the following list of Shared Image Gallery images referenced from the deployment template were not found:"
