Docker Desktop Windows Server

Docker Desktop for Windows is the Community Edition (CE) and is ideal for developers and small teams looking to get started with Docker and experimenting with container-based apps. Note Users are no longer disallowed from running Windows Server containers in process isolation mode on Windows 10 Enterprise or Professional for dev/test purposes.

In this post, I describe how to install WSL 2 to serve as the backend for Docker Desktop for Windows. Previously I've always worked with Linux in a Virtual Machine using something like VMWare or Virtual Box, but I decided to give Docker Desktop a try, and was pleasantly surprised by the experience!

I'll start by describing how to install WSL 2 based on the install documents, then show how to install Docker Desktop. Finally, I show the the experience of running a container and how it looks in Docker Desktop.

Installing WSL2

Www.docker.com › Docker-desktop › Getting-startedGetting Started With Docker Desktop For Windows Docker

The Windows Subsystem for Linux (WSL) is a way to run a full Linux environment on your Windows machine, without having to install a 'heavier' virtual machine, such as Virtual Box, VM Ware, or Hyper-V. WSL 2 also provides a mechanism for running Docker (with Linux containers) on your Windows machine. We'll install it as a prerequisite for Docker Desktop for Windows.

If you're running Windows Home, WSL 2 is the only way to run Docker Desktop. On Windows Pro, you can also use Hyper-V, but that is deprecated now, so WSL 2 is the way to go in all cases.

1. Install WSL 1

We'll start by installing WSL 1 by enabling the WSL feature.

Open PowerShell as Administrator (I hit the Start key, type powershell and hit ctrl+shift+enter to open an elevated command prompt). Run the following, to enable WSL 1

You should see the following:

That enables WSL, but we're going to enable the newer WSL 2 version, which Docker Desktop can use to run the VM it needs to run containers.

2. Enable the Virtual Machine feature

WSL 2 uses a lightweight VM, so you need to enable the Virtual Machine feature available in Windows 10 version 1903 and higher. In the same, elevated command prompt, run:

You should see something like the following:

3. Restart

Time to restart your machine to ensure everything is registered correctly.

4. Install the WSL 2 update

Download the WSL2 Linux kernel update package for x64 machines and install it.

Note, if you see the following error when running the update, make sure you've restarted your machine afer installing the WSL 1 and VM features:

The installer runs very quickly, and hopefully you'll see a confirmation screen, something like the following:

5. Set WSL 2 as your default version

This is an easy step, just run wsl --set-default-version 2 in any PowerShell window:

6. (Optional) Install a Linux distribution

We actually don't need to install a Linux distribution to use Docker Desktop, but if you want to shell into Linux directly, you'll need to install one. You can install a distribution directly from the Microsoft Store.

The first time you launch the distribution, the distribution will extract and install, and you'll need to set a username and password.

7. (Optional) Add to Windows Terminal

If you're using Windows Terminal (you should be!) you can configure it to open your WSL distribution. The easiest way to do this is to open up the settings.json file and reset it. You can do this by deleting the contents of the file—Terminal will automatically repopulate it with the defaults, which will include a tab for WSL.

Obviously you won't want to lose your setting customisations, so make sure to backup the contents of the file first!

You're looking for WSL in the profiles list—add that to you profile list, and you'll be able to quickly open up your WSL instance from Windows Terminal!

That's the prerequisite starter for Docker Desktop covered, so now lets get to the main course!

Installing Docker Desktop for Windows

1. Download and Install

Head to the Docker Desktop website and download the Installer for Windows.. This is a hefty ~500MB, but once it's finished, run the installer.

On the first screen, ensure you keep 'Install required components for WSL 2' checked:

After clicking OK, the installer will unpack a whole load of files:

Before finally prompting you to log out of your Windows account to complete the installation:

2. Logout and back in

The Docker Desktop installer will automatically log you out of your Windows account on completion. When you sign back in, you'll get a notification that Docker is starting the Linux Containers WSL 2 backend. Eventually, the main Docker Desktop window will pop up, and offer you a tutorial

3. Give it a try!

With Docker Desktop installed, you now have the docker command available in your command prompt:

Now it's installed, let's take it for a spin!

Trying out Docker Desktop for Windows

For simplicity, we'll run one of the .NET 5.0 sample apps available on DockerHub:

This is a simple Razor Pages app, packaged in a Docker image, and ready to run. You can see the Dockerfile for the app here. When you run the above command Docker will pull the image, run it and start listening:

Windows

If you navigate to http://localhost:8000/, you'll see the app running there—a Linux container, running on Windows 🤯

The interesting thing, which I didn't realise until I installed it, is that Docker Desktop for Windows installs a very nice UI for managing your containers!

If you click on the my-sample container row, you'll see the logs for the container:

You can also inspect the environment variables, view stats about the container, or click CLI to open a shell inside (exec into) the container! You can do all these things from the command line obviously, and if you're automating things, that's definitely the right option. For casual or local development, personally I find you can't beat a nice GUI!

Summary

In this post I described how to Install WSL, upgrade it to WSL 2, and how to install Docker Desktop. This requires a restart of Windows and a logout which is a bit annoying, but otherwise it went very smoothly. The Docker Desktop UI also looks very handy, in particular the ability to exec into a container—I'm always getting the CLI command wrong, so that will be very unseful!

Step 2: Customize and Push to Docker Hub

Docker Desktop Windows Server 2012

The last step used a Docker image which Microsoft publishes and maintains. Next step, create your own custom image. You should have a Docker ID, you probably created it to download Docker Desktop.

In your favorite text editor create a file called Dockerfile in the same C:temp directory. No extension, just Dockerfile. Paste in this code and save the file:

This tells Docker to use the same IIS base image, and create a layer that adds in the HTML you created in the last step. Instead of manually copying a file into the container, you will create an image with your HTML already inside it. To build the image, in your terminal, type:

Two things, first replace <YourDockerID> with your Docker ID. Also notice the “.” at the end of the line. That tells Docker to build in the context of this directory. So when it looks to COPY the file to /inetpub/wwwroot it will use the file from this directory.

You can run it:

And go to http://localhost:8081 to see the page - note your original container is still running and you can see it at http://localhost:8080.

Finally push to Docker Hub:

You may be asked to login if you haven’t already. Then you can go to hub.docker.com, login and check your repositories

Finally, stop and remove the running containers:
