Docker Windows Server Container Images

Docker Container Images for Windows Server 1709 and new tagging

Last week Microsoft announced new Windows Server 1709 and the new Windows Server 1709 container images. The new container images in Windows Server version 1709 are highly optimized, especially in size. So for example the new Nano Server Container Image in 1709 is 5x smaller than the Nano Server Container Image in Windows Server 2016.

Microsoft also made some changes to tagging which is interesting.

If you want to use the latest images of the container images based on the Windows Server 2016 (which is in the Long-Term Servicing Channel, LTSC) you just run:

This will give you the latest images of the Windows Server and Nano server container images. If you want to run a specific patch level of the Windows Server 2016 (LTSC)m images, you can run the following:

If you want to use the new Windows Server 1709 container images from the Semi-Annual Channel you can run the following

and again you cans also add a specific base OS container image by using a KB number:

If you already tried out the new container images during the development using the insider images, they still existing:

However, I am not sure what the plan for the insider images is going forward.

Docker for Windows Update Linux Containers

How to run Docker Linux Container on Windows 10 Fall Creator Update

I just blogged about how to run a Docker Linux Container natively on the new Windows Server version 1709. Docker today released a new update for Docker on Windows which also enables this scenario a little bit easier on your Windows 10 machine. It will ask you if you want to use the new feature to run Linux Containers natively on a Hyper-V Container running on Windows 10 (without the Moby VM).

As you can see the only thing right now you have to turn the feature on and off, since in this technical preview it is not yet possible to run Linux and Windows containers in parallel. But I guess soon that will be the case.

What you need is:

  • Windows 10 Fall Creators Update (Build 16299, Version 1709, RS3)
  • Docker for Windows 17.10.0-ce-win36 (13788) or higher

Enable Linux Containers on Windows

You can change the settings in the Docker Settings:

Docker for Windows Settings Enable Linux contianers on Windows

With hat setting on you can now run Linux Containers such as ubuntu on Windows directly, without having a Linux Virutal Machine running in the background to host the Linux containers.

Docker Run Ubuntu on Windows 10 Verions

Now you can also do some other fancy things like run the Azure CLI in a Linux Container on Windows 10.

Simple and effective, and it will be even more powerful when you can run Linux and Windows Container in parallel on Windows Sever and on Windows 10.

Windows Server 1709

Microsoft released Windows Server 1709

Microsoft just released the new Windows Server version 1709 which is the first release in the Semi-Annual Channel. The Semi-Annual Channel release cadence to deliver innovation at a faster pace, but you will also need to keep updating your systems to newer versions of Windows Server. As of today, you can download Windows Server 1709 from the Volume license portal or deploy it in Microsoft Azure, since it is available in the Azure Marketplace.

Windows Server 1709 Features and Improvements

Windows Server 1709 will drive innovation in the container space and in the Windows Subsystem for Linux, as well as some Cloud Host improvements in Hyper-V with new support for Storage Class Memory and more. Windows Server 1709 will be only available as Windows Server Core (Standard and Datacenter).

If you want to know more about the new features and improvements in Windows Server 1709, check out my blog post and check also out the Microsoft What’s new in Windows Server 1709 page.

What is next for Windows Server and System Center with a faster release cadence

Windows Server, version 1709 is only the first step in this new world of faster release cadences. The most important aspect of having new releases twice a year is customer feedback will shape the product. You can try the preview builds of Windows Server in the Semi-Annual Channel and provide feedback by joining the Windows Insiders program. You can also join the conversation in the Microsoft Tech Community where we have tons of professionals and experts sharing their learnings and answering questions.

Azure Nested Virtualization

Hyper-V Container and Nested Virtualization in Microsoft Azure Virtual Machines

Last week Microsoft announced some pretty cool new Azure Stuff, like the Azure Cloud Shell, Azure PowerShell 4.0, Azure Cosmos DB and much more.

In the session about Azure Compute, Microsoft introduced a bunch of new features, like new VM sizes, new experiences and new integration technology as well as updates to Azure Service Fabric, Azure Container Service and Azure Functions. One which really got my interest was the announcement about the new Virtual Machines sizes for Dv3 and Ev3, which will enable customers to use Virtualization inside their Windows Server Virtual Machines on Azure, enabled by Nested Virtualization from Windows Server 2016 Hyper-V. With that Dv3 and Ev3 Azure Virtual Machines are Nested Virtualization enabled.

Update: The new Azure Dv3 and Ev3 VM sizes are now available, and you can now use Nested Virtualization in Azure.

Azure Nested Virtualization and Hyper-V Containers

You can now run Hyper-V in Azure Virtual Machines and even more important you can now run Hyper-V Container inside Azure Virtual Machines. With the announcements for Windows Server 2016 supporting Hyper-V Containers running Linux and Windows Server this is great news. You will be able to create Container Hosts in Azure running Windows Server and create Windows and Linux Containers on the same Container Host.

Azure VM Sizes

By the way, if you want to run Hyper-V Container in Azure today, and you don’t want to wait until the Dv3 and Ev3 series are available you can run them inside Azure Service Fabric. So yes, Microsoft now allows you to run Hyper-V Containers in Azure Service Fabric.

Azure Nested Virtualization Demo

As you could see in the demo, they are offering quite large Virtual Machines with a lot of RAM, running on Intels Xeon E7 CPUs.

Hyper-V Windows Containers

Windows Server news from Microsoft Build 2017 – It is all about Container!

Microsoft is just running their annual Developer Conference call Build with some interesting news for developers on Azure, Database Servers, Visual Studio, PowerShell, .NET and much more. But Microsoft also had some interesting things to share about the future of Windows Server. In a blog post, Erin Chapple, General Manager Windows Server, shared some information what Microsoft is doing in the Windows server space and about the next first feature release which will be aligned with the Windows 10 Client Operating System and will be released this Fall.

Windows Server is joining the Windows Insider program – Microsoft will start releasing regular Windows Server Insider builds including container images, which will be available to all Windows Insiders.

Container-optimized Nano Server – The Windows Server team has closely partnered with he .NET Team to bring the .NET Core 2.0 work to Windows Containers with an optimized container image based on Nano Server. This will reduce the footprint of the .NET container image by 50 percent, which will also reduce startup time as well as density improvements.

Windows Subsystem for Linux (WSL) on Windows Server – At DockerCon Keynote we demonstrated a Linux container running natively on Windows Server. To enable this, the Windows Server team worked to bring the Windows Subsystem for Linux (WSL), also know as bash on Windows 10, to Windows Server. Together with Hyper-V isolation technology, the WSL will allow users to run Linux Containers on a Windows Server Container Host. The great thing here, there is also a choice on the Linux kernel, which will allow you to run different Linux distributions as containers.

Container Orchestration – Microsoft works with different container orchestration technologies, such as Docker swarm and Kubernetes to bring support for Windows Server Containers.

Container Storage – In Windows Containers you could use locally mounted volumes to store persistent data. As another investment in Containers, Microsoft is adding the ability to map SMB file-based storage directly into a container.

Starting this summer, Microsoft will begin to post early builds of the new Windows Server features, including container-optimized Nano Server images to the Docker Hub, support for Linux containers, Windows Subsystem for Linux (WSL), better orchestration support and SMB storage for containers in the Windows Insider program.

Aligned with the next release of Windows 10, these new features will be delivered as part of our first feature release this Fall. It will be available to customers with Software Assurance who commit to a more frequent release model. For customers who prefer the long-term servicing branch (LTSB) these features will be part of the next major release of Windows Server.

VCNRW Nano Server and Container

Video: VCNRW – Virtualization Community NRW recording about Nano Server and Windows Containers

A couple of weeks ago I had the chance to speak at the VCNRW – Virtualization Community NRW community event at the Microsoft Offices in Cologne. The recording of this session (in German) is now available on Microsoft Channel 9.

Nano Server and Containers (on Microsoft Channel 9)

Have a look at the latest Cloud Technologies from Microsoft. Learn about the next Microsoft Cloud Platform Server called Nano Server and Windows Containers. Both solutions are built for the future and will fundamentally change how we do IT. Learn why we need Nano Server and Windows Containers and how we deploy, manage and operate them.

Switch Windows Container to Hyper-V Container

Switch a Windows Server Container to a Hyper-V Container

With Technical Preview 4 of Windows Server 2016 made the new Hyper-V Containers available. With that you can now use Windows Server Container and Hyper-V Container. To run Hyper-V Containers you have to make sure, you have Hyper-V Nested Virtualization active for your Container Host VM.

If you create a new Container it will create a Windows Server Container by default, if you want to create a Hyper-V container you have to switch the RuntimeType to Hyper-V.

With the following command you can see which RuntimeType the Container has:

To change the runtime Type to Hyper-V Container you can use the following command:

So switch it back to a Windows Server Container you can use the following command:
