Microsoft have released a new build of Windows Server vNext for Insiders to test. The new build is 19008 and the core images are 20% smaller than previous versions:
Windows Server Core Container Images Are 20% Smaller
In what should be a significant win for any workflow that pulls Windows containers images, the download size of the Windows Server Core container Insider image has been reduced by 20%. This has been achieved by optimizing the set of .NET pre-compiled native images included in the Server Core container image. If you are using .NET Framework with Windows containers, including Windows PowerShell, use a .NET Framework image, which will include additional .NET pre-compiled native images to maintain performance for those scenarios, while also benefiting from a reduced size.
The new build is available as an ISO in 18 languages and an English VHDX file. You can download the build from here and these are the keys to activate the install:
