Install Docker In Windows Server 2012

Aug 27, 2018 Open the installer by double-clicking the.exe file. Choose “Yes” in the Windows security dialog box to allow the program to make changes to your PC. When the Docker Toolbox setup wizard starts, click the “Next” button. Choose the local folder for Docker Toolbox installation. Click the “Next” button. For developers, Windows 10 is a great place to run Docker Windows containers and containerization support was added to the the Windows 10 kernel with the Anniversary Update (note that container images can only be based on Windows Server Core and Nanoserver, not Windows 10). All that’s missing is the Windows-native Docker Engine and some image. Nov 03, 2016 1 Like. Friism (Michael Friis) November 7, 2016, 5:48am #3. is Docker compatible with windows server 2012 r2? No, Windows Server 2016 is required for running native Windows containers. The kernel containerization primitives are only available starting with WS 2016. To continue this series on Introduction to Containers for the SQL Server DBA, you will look at creating your own SQL Server on Windows containers. In Part 1, you have learned how to install Docker on Windows Server 2016. In Part 2, you installed Docker on a Linux CentOS server. Install-Package -Name docker -ProviderName DockerMsftProvider –verbose. Type A and press Enter to trust the Docker Package. It will install the windows containers feature along with docker service in the server. We need to reboot the server to complete the installation. Reboot the server core machine using the below command.

Initially, the inception of Docker containerization started out with Linux as its base platform. However, over the years, Docker and Microsoft have continuously grown their partnership, creating a conveniently consistent interface for building, shipping, and running applications without the usual dependence hurdles associated with virtual machines.

Though a huge number of enterprises are already using Docker on Windows platforms, there has been a number of subtle functionality disparities between Windows and Linux containers. However, Windows Server 2019 (1809 build) has successfully addressed most of the inconsistencies between Docker containers in Linux and Windows environments.

Requirements for Installation of Docker on Windows

Docker containers are powered by a Docker engine. Though initially designed for Linux, extensive work has been done to allow Docker containers to run on Windows and macOS environments.

To run Docker containers on a Windows platform, one prerequisite is the installation of a Windows server. You can do this in a physical server machine, on a cloud environment running in Azure, or an on-premise virtual machine.

Install the Hyper-V feature on your Windows server 2019

There are two distinct modes to run Decker containers on Windows platforms: Process isolation and Hyper-V isolation. With the Process isolation mode, the Docker containers share the OS kernel with the host platform, hence they are lightweight and identical to Linux system Docker containers.

On the other hand, the running of Docker containers in the Hyper-V mode is confined to a special nominal virtual machine. This enables improved compatibility and secure kernel-level. To run Docker containers in this mode, you must first enable Hyper-V in the host operating system.

The default operation mode for Docker installation on a Windows server is the operation mode (enabling Hyper-V is optional). However, it’s a prerequisite to enable the Hyper-V isolation mode if you need to run Linux containers on a Windows Server interface.

The OS build is another crucial determinant on the need for Hyper-V mode as Windows containers should be of the same build version as the container host OS’s version. Still, Windows container images with a lower build version than the container host OS can run with Hyper-V isolation.

To install Hyper-V on Windows Server 2019, run the PowerShell as Administrator and run the commands below:

Enable-WindowsOptionalFeature –Online -FeatureName Microsoft-Hyper-V –All -NoRestart

Install-WindowsFeature RSAT-Hyper-V-Tools -IncludeAllSubFeature

Next, restart your Windows Server VM.

Prerequisites for the container host

You must enable virtualization in the hosting Windows server platform to utilize Hyper-V isolation in your containers: enable hardware virtualization for a container host running on hardware and nested virtualization in the base interface for a container host running on a cloud space or Hyper-V.

Running Docker Containers on Windows Server 2019

Before running multiple isolated applications using Windows Containers, you need to activate (enable) the containers feature and install Docker on your Windows Server 2019. Here’s the process:

  1. Enable the containers feature in Windows Server 2019.

Run PowerShell as an Administrator and run this command:

Install-Module -Name DockerMsftProvider -Repository PSGallery -Force

This command will install the Docker-Microsoft Package Management Provider from the PowerShell Gallery.

When prompted to install and import NuGet provider, type Y and hit ENTER

  1. Install Docker on your Windows Server 2019

After installing the Containers feature on Windows Server 2019, it’s time to install the latest versions of Docker Engine and Docker Client. Run this command in your PowerShell session:

Install-Package -Name docker -ProviderName DockerMsftProvider

Accept the installation by selecting “Yes”, “Y” or “A” to Agree to all the installation requests.

After the completion of this installation, reboot your computer.

Restart-Computer –Force

You can check your installed Docker version via the PowerShell command:

Get-Package -Name Docker -ProviderName DockerMsftProvider


You can also confirm the installed Docker version using the docker –version command:

docker –version

You can opt to upgrade anytime by running the commands below on PowerShell:

Install-Package -Name Docker -ProviderName DockerMsftProvider -Update -Force

Then start the docker service.

Start-Service Docker

  1. Launch (Run) Docker Containers on Windows Server 2019

Run the following commands on PowerShell:

Start-Service Docker

After starting the Docker Engine service, proceed to download the pre-created .NET sample image on the Docker Hub registry:

docker pull microsoft/dotnet-samples:dotnetapp-nanoserver-1809

After the download, you can deploy a simple Docker container that runs the .Net ‘Hello World’ application:

docker run microsoft/dotnet-samples:dotnetapp-nanoserver-1809

After running the command, an ASCII image will be printed to the shell accompanied by the “Hello” message.

Running Linux Containers on your Window Server 2019

By default, Docker on Windows only runs Windows containers. To launch Linux containers on Windows Server, use the Docker Enterprise Edition Preview that comes with a full LinuxKit system to run Docker Linux containers.

  1. First, uninstall the already installed Docker CE.

Uninstall-Package -Name docker -ProviderName DockerMSFTProvider

Docker
  1. Enable Nested Virtualization in case you’re running Docker Containers on a Linux Virtual Machine running on Hyper-V.

Get-VM WinContainerHost Set-VMProcessor -ExposeVirtualizationExtensions $true

NOTE:WinContainerHost is the name of your virtual machine

  1. Install the Module Docker Provider

Install-Module DockerProvider

Install-Package Docker -ProviderName DockerProvider -RequiredVersion preview

A restart will be required after this operation

  1. Enable LinuxKit system to run Linux containers

[Environment]::SetEnvironmentVariable(“LCOW_SUPPORTED”, “1”, “Machine”)

  1. Restart the Docker Service after the change above and restart the Service Docker

Restart-Service docker

To switch back to running Windows containers, execute the following command in PowerShell:

[Environment]::SetEnvironmentVariable(“LCOW_SUPPORTED”, “$null”, “Machine”)

You have finally installed and configured Docker your Windows Server machine to run both Linux and Windows containers. We hope this guide was insightful.

Windows Server 2019 is the next long-term support release of Windows Server, and it's available now! It comes with some very useful improvements to running Docker Windows containers - which Docker Captain Stefan Scherer has already summarized in his blog post What's new for Docker on Windows Server 2019.

UPDATE: the second edition of my book Docker on Windows is out now. It focuses entirely on Windows Server 2019

You need Windows Server to run 'pure' Docker containers, where the container process runs directly on the host OS. You can use the same Docker images, the same Dockerfiles and the same docker commands on Windows 10, but there's an additional virtualization overhead, so it's good to use a Windows Server VM for test environments.

On Windows 10 Docker Desktop is the easiest way to get started

If you want to check out the newest version of Windows Server and get running Docker containers, here's what you need to do.

Get Windows Server 2019

You can download the ISO to install Windows Server 2019 now, from your Visual Studio subscription if you have one, or a 180-day evaluation version if you don't. VMs with Windows Server 2019 already deployed will be available on Azure shortly.

The installation procedure for 2019 is the same as previous Windows Server versions - boot a VM from the ISO and the setup starts. I prefer the core installation with no GUI:

I installed Server 2019 onto a Hyper-V VM running on my Windows 10 machine, with the VM disks stored on an external SSD drive. The setup finished in a few minutes, and it runs very quickly - even with just 4GB RAM allocated.

You can also upgrade from previous Windows Server versions to 2019 using the ISO.

Connect to the Server

When you RDP into a Windows Server Core machine you just see a command prompt. The first time you connect you'll need to set the password for the default Administrator account. Then I like to set PowerShell as the default command shell, so whenever you RDP you get into a PowerShell session:

Configure Windows Features

To run containers you need to enable the Containers feature, and for a non-production VM I also disable Windows Defender to stop it burning CPU cycles. You'll need to reboot after these steps:

Configure Windows Updates

You'll want to make sure you have the latest updates, but then I disable automatic updates so I only get future updates when I want them. There's no GUI in Windows Server Core, so run sconfig and then select:

  • option 5, to set Windows Updates to manual

  • option 7, to enable Remote Desktop Access to the server

  • option 6, to download and install all updates

Then you're ready to install Docker.

Install Docker on Window Server 2019

Windows Server licensing includes the licence cost for Docker Enterprise, so you can run the enterprise edition with production support for containers from Microsoft and Docker.

The latest Docker Enterprise engine is version 19.03 18.03, which you can explicitly install with PowerShell:

This sets up Docker as a Windows Service, which you need to start:

Pull the Windows Base Images

Any Docker containers you run on Windows Server 2019 will be based on Windows Server Core or Nano Server. You'll need both those images, and be aware that the base images are now hosted on Microsoft's container registry, MCR:

Windows Server Download

These images are tiny compared to the Windows Server 2016 versions. Windows Server Core has shrunk from over 10GB to a 1.5GB download, and Nano Server has shrunk from over 1GB to a 90MB download!

[Optional] Pull the .NET Core Images

The .NET Core team released versions of their SDK and runtime images as soon as Windows Server 2019 launched. You can pull those now and start running your .NET Core apps in 2019 (there are also .NET Framework SDK and ASP.NET images available - hopefully SQL Server will get some attention soon...)

The upstream Docker images are still listed on Docker Hub, so that's where you go for discovery - but they get served from Microsoft's own image registry, MCR.

Try it Out!

I've pushed an updated version of my .NET Core whoami image, so you can try out ASP.NET Core 3.0 running in Windows Server Core 2019 containers:

One of the enhancements for Docker in Windows Server 2019 is that loopback addresses now work, so you can visit this container using localhost on the server, and using the same published port from an external machine:

And in Swarm Mode...

I'll post a longer explanation of what you can do with Docker in Windows Server 2019 that you couldn't do in Windows Server 2016, but here's just one other thing: Windows Server 2019 now supports ingress networking for Docker swarm mode. That means you can run multiple containers on one server, all listening on the same port, and Docker will load-balance incoming requests between the containers.

Windows Server

I have lots more detail on this in my Pluralsight course Managing Load Balancing and Scale in Docker Swarm Mode Clusters

Switch your server to a single-node swarm:

Install Docker In Windows Server 2012 Free

Now deploy the whoami app as a swarm service, with multiple replicas and a published port:

Install Docker In Windows Server 2012 64-bit

Now when you browse to the VM from outside, Docker will load-balance requests across the five containers which are hosting the service:

Windows Server 2019 is an evolution to the container functionality you get with Docker. Windows Server 2016 is still perfectly fine for production, but 2019 brings Windows containers much closer to feature parity with Linux containers, and smooths over some things which are tricky in 2016.

And the next big thing is Windows support in Kubernetes, which is expected to GA before the end of the year :) went GA this year. Windows containers are now supported in mixed Linux-Windows Kubernetes clusters - find out more from my post Getting Started with Kubernetes on Windows.
