This topic pertains to using the VM Clouds gallery in Windows Azure Pack for Windows Server. Gallery items are virtual machine roles that serve as standard and reusable artifacts that hosting service providers can use to provide offerings to their tenants. In Windows Azure Pack, you can add a gallery item to a plan that is subscribed to by tenants. Virtual machine roles represent a scalable tier of virtual machines that can be provisioned by a tenant using a single process. Examples of workloads that can be created by virtual machine roles could include a single virtual machine, an Active Directory Domain Controller, a SQL Server cluster, or Internet Information Services (IIS) web farm.
For information about obtaining gallery resources, see the Downloading and Installing Windows Azure Pack Gallery Resource. For information about creating virtual machine roles, see the System Center 2012 R2 Virtual Machine Role Authoring Guide.
Service Provider Foundation allows you to import gallery items into Virtual Machine Manager from downloaded resource packages. In addition, the gallery items are tracked in the SPFDB database. By doing so, the gallery items will be immediately available for viewing in management portal for administrators in Windows Azure Pack.
You can also use Service Provider Foundation Admin web service or cmdlets to get a gallery package, item, or the icon for an item. This allows portal developers to create UI elements and functionality that offer tenants a compelling experience in selecting gallery items.
The following example shows how to use Windows PowerShell to import a gallery item from a package and use its contents, and then remove it.
PS C:\> # The first command gets the path to the resource package and stores it in the $Path variable. PS C:\> # The second command gets a System.IO.FileStream object of the package. PS C:\> # The third command imports the package. PS C:\> $Path = "c:\packages\create.resdefpkg" PS C:\> $FStream = New-Object IO.FileStream $Path, Open PS C:\> Import-SCSPFVMRoleGalleryItem -Package $FStream PS C:\> PS C:\> # Get an item from the gallery by specifying its name and store it in the $galItem variable. PS C:\> $galItem = Get-ScSpfVmRoleGalleryItem -Name 570569955cbfb62b374358b34467020750f65c PS C:\> PS C:\> # Get the icon object by specifying the required parameters with the variable. PS C:\> # The IconFileName parameter is explicitly specified in case the variable has a null value for the icon file name. PS C:\> $galItemIcon = Get-SCSPFVMRoleGalleryItemIcon -Name $galItem.Name -Publisher $galItem.Publisher -Version $galItem.Version -IconFilename "contoso.ico" PS C:\> PS C:\> # Get the package of the gallery and stores it in the $galPkg variable. This cmdlets returns an System.IO.MemoryStream object. PS C:\> $galPkg = Get-SCSPFVMRoleGalleryItemPackage -Name 570569955cbfb62b374358b34467020750f65c -Publisher Microsoft -Version 22.214.171.124 PS C:\> PS C:\> # One use of the memory stream of the package is to save it to a file on your computer. PS C:\> $fs = New-Object IO.Filestream "c:\@tmp\gal.bin", Create PS C:\> $binwriter = New-Object IO.BinaryWriter $fs PS C:\> $binwriter.Write($galPkg.ContentStream.ToArray()) PS C:\> $fs.Close() PS C:\> $binwriter.Close() PS C:\> PS C:\> # Import the package that was just saved, using the PackageFilePath parameter. PS C:\> Import-ScSpfVmRoleGalleryItem –PackageFilePath "C:\@tmp\gal.bin"
Service Provider Foundation provides the following cmdlets for the gallery:
