Remove All Docker Container Images

New Windows Server 2019 Container Images

Microsoft today released the new Windows Server 2019 again. After they quickly released Windows Server 2019 during Microsoft Ignite, they removed the builds again, after some quality issues. However, today Microsoft made the Windows Server 2019 builds available again. Microsoft also released new Windows Server 2019 Container Images for Windows, Windows Server Core and Nano Server.

Download Windows Server 2019 Container Images

You can get them from the new Microsoft Container Registry (MCR).

Microsoft was hosting their container images on Docker Hub until they switch to MCR (Microsoft Container Registry). This is now the source for all Windows Container Images like Windows Server 2019, Windows Server 2016 and all the Semi-Annual Channel releases like Windows Server, version 1709 or Windows Server, version 1803.

Download the Windows Server 2019 Semi-Annual Channel Container Images (Windows Server, version 1809). This includes also the new Windows Container Image.

The Windows Server Core Image is also available as a Long-Term Servicing Channel Image:

However, if you want to browse through container images, Docker Hub continues to be the right place to discover container images. Steve Lasker wrote a blog post about how Microsoft syndicates the container catalog and why.

Download Windows Server 2016 and Windows Server SAC Container Images

Also the existing Windows Server 2016 and Windows Server, version 1803 and Windows Server 1709 container images moved to the Microsoft Container Registry (MCR).

You should also make sure to update your Dockerfile references:

Old Windows Server Dockerfile reference

FROM microsoft/windowsservercore:ltsc2016

New Windows Server Dockerfile reference

FROM mcr.microsoft.com/windows/servercore:ltsc2016

Removing the “latest” tag from Windows Images

Starting 2019, Microsoft is also deprecating the “latest” tag for their container images.

We strongly encourage you to instead declare the specific container tag you’d like to run in production. The ‘latest’ tag is the opposite of specific; it doesn’t tell the user anything about what version the container actually is apart from the image name. You can read more about version compatibility and selecting the appropriate tag on our container docs.

Removing Container Images

Remove All Docker Container Images

If you want to remove existing container images from your PC, you can run docker rmi to remove a specific image. You can also remove all containers and container images with the following commands:

Windows Server 2019

Windows Server 2019 – What is coming Next

A while ago Microsoft announced the next key versions Windows Server 2019 and System Center 2019. And a couple of weeks ago, at the Windows Server Summit, Microsoft was taking more about what is new in Windows Server 2019. Microsoft also talked a lot about the positioning of Windows Server and what we can expect in the future. With the news finally released to the public, I can start talking and blogging about the new features and investments. I decided to create a series of blogs, to show the world the great new features. This blog post here, should give you a high level overview about how Microsoft is investing in Windows Server 2019.

Windows Server – The Power behind the Intelligent Cloud and the Intelligent Edge

Intelligent Cloud and Intelligent Edge

Windows Server is not only powering the Intelligent Edge where you have a great Software-Defined Datacenter plaform running Hyper-V or Stroage Spaces Direct, or as application platform. It is also powering the Microsoft Azure Intelligent Cloud. Windows Server is running the foundation of the platform of Azure and also many many services running in Microsoft Azure and Microsoft Azure Stack. If the innovation happening in the Microsoft Public Cloud, we as customers also benefit from that.

Windows Server – Hybrid Cloud in the DNA

Windows Server Hybrid Cloud

Windows Server is a great platform and it runs where ever you are. If you run on-premises in your Software-Defined Datacenter running in on physical hardware or in virtual machines or on Azure Stack, Windows Server is your platform. If you are running in the Public Cloud, Windows Server is not only the platform powering Azure. Windows Server is also a great platform for you to run application in Microsoft Azure or other cloud services providers.

Azure Hybrid Benefit for Windows Server

Azure Hybrid Benefit for Windows Server Reserved Instances

The Azure Hybrid Benefit for Windows Server is also a great option to run Windows Server workloads in the cloud. It allows customer to leverage the licensing they already have. This can bring down cost by a huge factor, and this together with Azure Reserved VM Instances up to 82%.

Windows Server 2019 – Innovation and Investments

Windows Server 2019 Investments

If we have a look at the investments done in Windows Server 2019, we can see that we can categorize them in 4 categories.

  • Hybrid Datacenter Platform
  • Security
  • Application Innovation
  • Hyper-Converged Infrastructure

Unique hybrid datacenter platform

Windows Server 2019 brings new functionality and features to extend your datacenter to Azure to maximize existing investments and gain new hybrid capabilities. To achieve this Microsoft brings improvements to Windows Server 2019 like built-in Azure Active Directory integration, Azure Backup, Azure Site Recovery, Storage Migration Services and many more.

Enhanced security capabilities

One of the key factors in today’s IT landscape is security. Microsoft started the journey by bringing enhanced security features to Windows Server 2016. With Windows Server 2019 Microsoft improves these security features of their server operating system. Microsoft adds new capabilities like Shield Virtual Machines for Linux, Exploit Guard, Encrypted Virtual Networks and under a lot of others. My favorite, the integration of Windows Defender Advanced Thread Protection or Windows Defender ATP.

Faster innovation for applications

With the Semi-Annual Channel releases of Windows Server, Microsoft already released some great investments to enable developers and IT pros. These allow them to create cloud native apps or modernize their traditional apps using containers and micro-services. In Windows Server 2019, Microsoft goes one step further and releases the SAC Improvement s like Linux Containers on Windows Server and the Windows Subsystem for Linux on Windows Server to the LTSC release. Microsoft also invest heavily to improve the container experience on Windows Server, by optimizing the container images for Server Core and Nano Server, a new Windows Container Image and better integration into orchestrators like Kubernetes and Service Fabric.

Unprecedented Hyper-converged Infrastructure

Microsoft is also improving your software-defined datacenter experience to achieve greater efficiency and security. With Windows Admin Center, Microsoft introduced a new web-based management UI which will be a perfect solution to manage your Windows Server 2019 servers. However, Microsoft is also investing in more hardware support like Storage Class Memory support. But also, on adding scale, resilience and performance improvements to your Storage Spaces Direct deployments. This includes improvements like Cluster Sets, improved performance for Mirror-accelerated parity volumes and much more.

In the next couple of days and weeks I will release some blog posts. These will covering the new features and improvements in Windows Server 2019 with a little more technical depth. And I am sure we will even have more to share after Microsoft Ignite. So ,stay tuned and follow my blog 🙂



Windows Container Images

The New Windows Container Image

At Microsoft Build 2018, Microsoft announced a new Windows container image, next to the Windows Server Core container image and the Nano Server container image. This new Windows container image is for applications and workloads which need additional API dependencies beyond Nano Server and Windows Server Core.

With the release of the latest Windows 10 Insider Preview (Build 17704), you can now download a preview of that container image. Your container host will need to run at least on the Windows Insider build 17704.

Windows Container Image

The IT world is transforming and Microsoft can see a huge demand by customers for containers. However the container images available today, Nano Server and Windows Server Core are lightweight versions of Windows and not including some of the components of Windows. A huge scenario for containers is to put legacy applications into containers. With the new Windows container image, Microsoft is offering a new option for applications who need more components which are not included in Windows Server Core, like DirectX or proofing support.

Microsoft Windows Container Images

As of today, Microsoft offers 3 container images in preview:

ImageVersionSize
mcr.microsoft.com/nanoserver-insider10.0.17704.1000232 MB
mcr.microsoft.com/windowsservercore-insider10.0.17704.10003.38 GB
mcr.microsoft.com/windows-insider10.0.17704.10008.07 GB

Getting started with Windows Containers

First you need to have a host running Windows Insider Preview Build 17704 or higher. After that you can simply use docker to get the latest Insider container images from the Microsoft Container Registry:

You can read more about the new Windows Container image here on the Microsoft Virtualization Blog.

We hope to see you there!



Azure Kubernetes Service

Azure Kubernetes Service (AKS) – The best place to host your containers

Microsoft today at Build 2018 announced that they will rename Azure Container Service (AKS) to Azure Kubernetes Service (AKS).

Azure Kubernetes Service (AKS) manages your hosted Kubernetes environment, making it quick and easy to deploy and manage containerized applications without container orchestration expertise. It also eliminates the burden of ongoing operations and maintenance by provisioning, upgrading, and scaling resources on demand, without taking your applications offline.

  • Drastically simplifies how you build and run container-based solutions without deep Kubernetes expertise
  • Auto Update, auto scale
  • New capabilities integrated with dev tools and workspaces, CI/CD networking, monitoring tools, etc.
  • All included in the Azure Portal

Create Azure Kubernetes Service AKS

This will be a great services to run containerized workloads in a very simple manor and reduce management overhead.

Azure Kubernetes Service (AKS) will also be available on Azure Stack, as announced in the Azure Stack Roadmap update a couple of months ago.

Azure Kubernetes Service (AKS) on Azure Stack
Managed Kubernetes with Azure Kubernetes Service (AKS) on Azure Stack will make it even easier for Azure Stack users to manage and operate Kubernetes environments in the same ways as they do in Azure, without sacrificing portability. This new service features an Azure-hosted control plane, automated upgrades, self-healing, easy scaling, and a simple user experience for both developers and cluster operators. With Container Service, customers get the benefit of open source Kubernetes without complexity and operational overhead. This update applies primarily to Azure Stack users.

With AKS on Azure and Azure Stack. and other services like the Azure Container Registry, Docker for Windows, Windows Server and Hyper-V Containers, Visual Studio Team Services Integration for Azure and Containers, the Microsoft container story becomes very strong. It allows you to run your container workloads in a very simple CI/CD pipeline (VSTS), deployment on Managed Kubernetes (AKS) and deploy it where ever you need it, in the public cloud (Azure) or on-premise (Azure Stack).

Yes Microsoft still has ACS (Azure Container Service), which allows you to deploy different pre-configured container environments and orchestrators, like Docker Swarm, Kubernetes, DC/OS, for scalable deployments and management of containerized workloads.
