Azure VM Image Builder Template Repo

Get started now, this repo contains mutliple examples and test templates for Azure VM Image Builder (Public Preview).

What is Image Builder?? Get started with the short intro video below, or go straight to the Quick Starts below.

drawing

  1. Quick QuickStarts Examples. You can run these immediately using the Azure CloudShell from the Portal, and see multiple scenarios that the VM Image Builder supports.

  2. Azure Resource Manager (ARM) Image Builder Examples. The beauty of these examples, they are heavily parameterized, so you just need to drop in your own details, then begin image building, or integrate them to existing pipelines.

Details below..

Deprecations & Notifications

  • As of the 4th of June, the service will reject templates that do not contain "identity", with a user assigned identity.
  • This means any templates created before 2019-05-01-preview will not be run, and not supported.
  • The 2020-02-14 API requires:
    • identity is mandatory
    • vnetConfig is now one property, subnetId, this is the resourceID of the subnet.
  • Please see the May 2020 Update for details on how to mitigate the above.

Whats coming!

  • AIB AZ CLI module / PS cmdlets - this will simplify the image creation even more!
  • GA - Early Q4 2020

More details on features in API 2020-02-14!

These details are being added to Azure docs and examples now, but for those who want a sneak peak...

Support for more Shared Image Gallery (SIG) Properties

  • Specify your own SIG version (optional) Previously AIB would automatically generate a montonic version based on datetime, this works well if you just want to keep re-running the template every month, as you don't need to modify the SIG distribution. However, feedback was that many customers would like to use existing versioning schemes, to use these, simply append a version to the SIG resourceID:
"galleryImageId": "/subscriptions/<subscriptionID>/resourceGroups/<rgName>/providers/Microsoft.Compute/galleries/<sharedImageGalName>/images/<imageDefName>/versions/1.1.1"
}
  • storageAccountType (optional) AIB supports specifying these types of storage for the image version that is to be created:
    • "Standard_LRS"
    • "Standard_ZRS"

For more information on these options, see SIG documentation

  • excludeFromLatest (optional) This allows you to mark the image version you create not be used as the latest version in the SIG definition, the default is 'false'.

A complete example, showing all the properties:

{   
    "type": "SharedImage",
    "galleryImageId": "/subscriptions/<subscriptionID>/resourceGroups/<rgName>/providers/Microsoft.Compute/galleries/<sharedImageGalName>/images/<imageDefName>/versions/1.1.1",
    "runOutputName": "<runOutputName>",
    "artifactTags": {
        "source": "azureVmImageBuilder",
        "baseosimg": "windows2019"
    },
    "replicationRegions": [
        "<region1>",
        "<region2>"
    ],
    "storageAccountType" : "Standard_ZRS",
    "excludeFromLatest" : true

}

Support for Plan_Info

Specify paid Market Place Offerings as a source:

    "source": {
        "type": "PlatformImage",
        "publisher": "RedHat",
        "offer": "rhel-byos",
        "sku": "rhel-lvm75",
        "version": "7.5.20190620",
        "planInfo": {
            "planName": "rhel-lvm75",
            "planProduct": "rhel-byos",
            "planPublisher": "redhat"
       }

Cancel a running build

If you are running an image build that you believe is incorrect, waiting for user input, or you feel will never complete successfully, then you can cancel the build.

The build can only be cancelled any time, if the distribution phase has started you can cancel, but you will need to clean up any created images. The cancel command does not wait for cancel to complete, please monitor lastrunstatus.runstate for canceling progress, using these status commands.

Examples of cancel commands:

Invoke-AzResourceAction -ResourceName $imageTemplateName -ResourceGroupName $imageResourceGroup -ResourceType Microsoft.VirtualMachineImages/imageTemplates -ApiVersion >> API  "2019-05-01-preview" -Action Cancel -Force
az resource invoke-action \
     --resource-group $imageResourceGroup \
     --resource-type  Microsoft.VirtualMachineImages/imageTemplates \
     -n helloImageTemplateLinux01 \
     --action Cancel

SERVICE UPDATE May 2020: ACTION NEEDED by 26th May - Please Review

We are making key changes to Azure Image Builder security model, this will be a breaking change, therefore we require you to take these before 26th May 0700 Pacific Time.

The change - Azure Image Builder Templates (AIB) must contain a populated identity property, and the user assigned identity must have permissions to read and write images.

Impact - From the 26th May 0700 we will not accepting any new AIB Templates or process existing AIB Templates that do not contain a populated identity. This also means any templates being submitted with api versions earlier than 2019-05-01-preview will not be be accepted either.

Why? - As well as allow us to prepare for future features, we are simplifying and improving the AIB security model, so instead of you granting permissions the AIB Service Principal Name, to build and distribute custom images, and then a user identity to you will now use a single user identity to get access to other Azure resources.

Actions Required

1. Create a user assigned 'identity'

2. Grant the permissions to the user assigned identity to the resource groups

3. Update your JSON templates with the identity property.

4. Submit your JSON template to the service.

5. Remove the old version of the template that does not contain property.

6. Remove previously granted role assignments from the SPN

For full details and the next potential breaking change, please review the May Service Update document.

If you have any questions, please review the above and FAQs, and if you cannot find them, please raise questions on GitHub issues.

Thanks,

27th May 2020 Update - NEW API VERSION - ACTION REQUIRED

As you may have noticed, we have now made identity a mandatory parameter in the template, this has multiple advantages, as described above, but this was also needed in preparation for our new API release, 2020-02-14, that will be available in all regions on the 27th May, by 0700 Pacific.

We are in the process of updating all the documentation, new features, and end to end examples, but the main breaking changes are:

  • identity is a mandatory requirement, please review the May Service Update document, on how to add this to your templates.
  • vnetConfig - this specification is changing, from providing, name, subnetName, resourceGroupName to just subnetId, for example:
    "vnetConfig": {
        "subnetId": "/subscriptions/<subscriptionID>/resourceGroups/<vnetRgName>/providers/Microsoft.Network/virtualNetworks/<vnetName>/subnets/<subnetName>"
        }
    }

What does this mean for existing templates and new templates created?

New Templates

If you create a new AIB template, and do not specify the API version in the calling client like below, then the template will be created using the new API version. This is because the calling client API version will override whatever exists in the AIB template.

az resource create \
    --resource-group $imageResourceGroup \
    --properties @existingVNETLinux.json \
    --is-full-object \
    --resource-type Microsoft.VirtualMachineImages/imageTemplates \
    -n existingVNETLinuxTemplate01

If you specify the API version using the calling client, like below, this will be created using the specified API version:

New-AzResourceGroupDeployment -ResourceGroupName $imageResourceGroup -TemplateFile $templateFilePath -api-version "2019-05-01-preview" -imageTemplateName $imageTemplateName -svclocation $location

Existing Templates

Once the new API is released, calling clients will default to use the new API version. Therefore, if you have existing templates that were created using the previous API version 2019-05-01-preview, in order to run, view properties, or delete them, you will need to specify the API version in the calling client, for example:

Getting the template status AZ CLI:

az resource show \
    --resource-group <imageTemplateResourceGroup> \
    --resource-type Microsoft.VirtualMachineImages/imageTemplates \
    --api-version 2019-05-01-preview
    -n <imageTemplateName>

Getting the template status PowerShell:

If you use the current documented method, then ensure the API version matches the previous API version 2019-05-01-preview.

$urlBuildStatus = [System.String]::Format("{0}subscriptions/{1}/resourceGroups/$imageResourceGroup/providers/Microsoft.VirtualMachineImages/imageTemplates/{2}?api-version=2019-05-01-preview", $managementEp, $currentAzureContext.Subscription.Id,$imageTemplateName)

Deleting Templates AZ CLI:

az resource delete \
    --resource-group <imageTemplateResourceGroup> \
    --resource-type Microsoft.VirtualMachineImages/imageTemplates \
    --api-version 2019-05-01-preview
    -n <imageTemplateName>

Deleting Templates PowerShell:

Remove-AzResource -ResourceId $resTemplateId.ResourceId -Force -ApiVersion "2019-05-01-preview"

FAQs

  • What about the AIB Azure DevOps? - The DevOps task is hard coded to use an API version, this will be updated, but continue to work without interuption.

  • When will we announce the new functionality? - The new features will be documented by 28th May

  • Can I use existing documentation? - Yes, examples that have breaking changes will be updated.

March 2020 Updates

It has been a busy year already, and we are so pleased to announce this new functionality:

  • Removal of Public IP address requirement, and use an existing VNET
    • You can now allow image builder to use your existing VNET, so you can connect to existing configuration servers (DSC, Chef, Puppet etc.), file shares, or any other routable servers/services.
    • Try the end 2 end Windows and Linux examples now!
  • European Region Support
    • We now the AIB service in NorthEurope and WestEurope!
  • Windows Update customizer
  • 'Latest' image version support
    • Instead of you need to specify a version for Azure Market Place (AMP) images, you can now specify. When the image is created, AIB will use the latest version. This means you can rerun the same image template after the source images in AMP are updated, such as monthly.
  • Permissions documentation
    • We listened to feedback for clarity on permissions required for AIB, and be more granular on permissions required.
    • The quickstarts and solutions are being updated with new permission enablement steps over time.
  • Networking documentation
    • We have documented details for AIB networking, options, and requirements.
  • DevOps Task Update
    • Windows Update - Support for running Windows Update at end of task
    • Change VM size - Change the VM size to make resource intensive image builds faster, and also build on specilist VM sizes, such as GPU or HPC enabled sizes.
  • RHEL ISO Source Deprecation
    • We are removing this functionality from image builder, as there are now RHEL Bring Your Own Subscription images, please review the timelines below:
      • 31st March - Image Templates with RHEL ISO sources will now longer be accepted by the resource provider.
      • 30th April - Image Templates that contain RHEL ISO sources will not be processed any more.

The offical Microsoft docs for image builder will be updated this month to relect these updates.

December 2019 Updates Part 2

The work never ends, latest customization support:

  • osDiskSizeGB

  • There will be more updates in January! On behalf of the team, thank you to everyone who has tried Image Builder, and given feedback, we really appreciate it. Happy Holidays!!!!

December 2019 Updates

We constantly update the Image Builder Service, and its been a while since we summarized recent updates here:

  • PowerShell Customizer Elevated Permissions

    • PowerShell Support for running commands and scripts with elevated permissions

  • Checksum File Validation

    • PowerShell / Shell / File Customizer Support for checkSum
    • Checksum the file a file locally, then Image Builder will checksum and validate.
