For more information about the values you can specify for an image definition, see Image definitions.Ĭreate the image definition using New-AzGalleryImageDefinition. Image definition names can be made up of uppercase or lowercase letters, digits, dots, dashes and periods. They are used to manage information about the image versions that are created within them. Image definitions create a logical grouping for images. Description 'Azure Compute Gallery for my organization' ResourceGroupName $resourceGroup.ResourceGroupName ` The following example creates a gallery named myGallery in the myGalleryRG resource group. Gallery names must be unique within your subscription.Ĭreate a gallery using New-AzGallery. Allowed characters for gallery name are uppercase or lowercase letters, digits, dots, and periods. In the following example, a resource group named myGalleryRG is created in the EastUS region: $resourceGroup = New-AzResourceGroup `Ī gallery is the primary resource used for enabling image sharing. $sourceVM = Get-AzVM `Ĭreate a resource group with the New-AzResourceGroup command.Īn Azure resource group is a logical container into which Azure resources are deployed and managed. This example gets a VM named sourceVM from the myResourceGroup resource group and assigns it to the variable $sourceVM. Once you know the VM name and what resource group, you can use Get-AzVM again to get the VM object and store it in a variable to use later. You can see a list of VMs that are available in a resource group using Get-AzVM. Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press enter to run it. You can also launch Cloud Shell in a separate browser tab by going to. To open the Cloud Shell, just select Try it from the upper right corner of a code block. It has common Azure tools preinstalled and configured to use with your account. The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. Image versions can be used multiple times. Like a managed image, when you use an image version to create a VM, the image version is used to create new disks for the VM. You can have multiple versions of an image as needed for your environment. It is a definition of a type of image.Īn image version is what you use to create a VM when using a gallery. This includes whether the image is Windows or Linux, release notes, and minimum and maximum memory requirements. Image definitions are created within a gallery and carry information about the image and requirements for using it internally. Like the Azure Marketplace, a gallery is a repository for managing and sharing images and VM applications, but you control who has access. An image source can be an existing Azure VM that is either generalized or specialized, a managed image, a snapshot, or an image version in another gallery. This is a resource that can be used to create an image version in a gallery. The Azure Compute Gallery feature has multiple resource types: Resource Choose which images you want to share, which regions you want to make them available in, and who you want to share them with. The Azure Compute Gallery lets you share your custom VM images with others. Custom images can be used to bootstrap configurations such as preloading applications, application configurations, and other OS configurations. Custom images are like marketplace images, but you create them yourself. OverviewĪn Azure Compute Gallery simplifies custom image sharing across your organization. When working through the tutorial, replace the resource names where needed. If needed, you can see the PowerShell quickstart to create a VM to use for this tutorial. To complete the example in this tutorial, you must have an existing virtual machine. The steps below detail how to take an existing VM and turn it into a re-usable custom image that you can use to create new VMs.
