For those that have been following the Windows Insider Preview Builds, Windows Server 2019 Preview 17709 has been released as of a couple of days ago. Additionally, this is the first Windows Server 2019 Preview that has the new preview build of Hyper-V server released. This release has a lot of new features and functionality surrounding containers, including some new features with group managed service accounts and a new base image of Windows. Let’s take a look at Windows Server 2019 Preview 17709 with New Hyper-V Released and some of the notables to mention with this release and previous builds of Windows Server 2019.
Windows Server 2019 Preview 17709 with New Hyper-V Released
With this release containers has certainly received some attention with new features and functionality including:
- Group Managed Service Accounts or gMSA – Scalability and reliability of the gMSA managed containers has been improved when accessing network resources. Microsoft has worked on authentication errors with single gMSA accounts and multiple container instances. Also, the name of the container’s host no longer needs to be the same as the gMSA. In previous builds, there was also a bug that prevented using gMSAs with Hyper-V isolated containers.
- New Windows Base Image – A new base image of Windows has been added to the Windows Server container collection. This is an image in addition to the NanoServer and WindowsServerCore container images. This new image contains more components than either the NanoServer or the WindowsServerCore container images which allows further extended support of applications with various API dependencies. The new container image was born from a use case that presented itself with customers who wanted to move legacy applications into containers. The then current Windows container images simply didn’t have the components to support what many customers needed in conjunction with these legacy applications. Other use cases involving DirectX needs within containers are no possible with the new Windows container image.
Obtaining the Latest Windows Container Image
If you are running a container host on Windows Insider build 17704, you can get this container image using the following command:
- docker pull mcr.microsoft.com/windows-insider:10.0.17704.1000
For the latest version, run:
- docker pull mcr.microsoft.com/windows-insider:latest
Microsoft recommends for compatibility reasons we recommend running the same build version for the container host and the container itself.
