Running Docker containers on a Windows 10 PC has been difficult for the last few years. It’s even more difficult if you want to run VirtualBox virtual machines (VM) at the same time. A casual Google search will turn up droves of postings saying that you absolutely can not do both at once.
The problem is that Docker on Windows required you to enable the Hyper‑V hypervisor but VirtualBox 5.x will not run while Hype‑V is active. The docker+VM on Windows OS question has been asked and answered so many times over the years that search results are flooded with the same outdated answer: No, you can’t have both. For some of us, this gets further complicated by people saying you can’t even use Hyper‑V at all on the Windows 10 Home version. Well, things are changing — but you have to really dig deep on the web to get the info you need to make it happen.
Two recent changes have turned things around. First, VirtualBox 6 has an ‘experimental’ support for Hyper‑V. Second, the upcoming Windows Subsystem for Linux version 2 fully supports docker using Hyper‑V, even on Windows Home edition.
WSL2
Windows Subsystem for Linux (WSL) is really great for developers who want to install Windows on their PC. It allows you to install a Linux as a peer operating system to Windows that you can easily access through a Linux terminal. WSL version 1 did have some limitations though. A big one for me is that the system call emulation layer Microsoft provides could not support Docker.
WSL2 is big update—faster file system, support for directly running the Linux kernel on Hyper‑V. It is scheduled for the “20H1” update that will be released in the spring of 2020—but you can get it now if you join the Windows Insider program. Instructions for that are found in the Windows Insider Program User Guide. Once you have an updated version of Windows, install of WSL2 is easy enough if you follow the instructions on Microsoft’s website.
VirtualBox 6
Installing VirtualBox 6 is simple and you can find the install on the VirtualBox download page. It can be a little tricky to get some VMs running now that you have Hyper‑V enabled. For me, when I tried to restart an old VM, or create a new one using the defaults, I would get an error right away.
To get your VMs working, you will need to go into the VM settings, choose the System section, go into the Acceleration tab, and select Hyper‑V as the Paravirtualization Interface. You may also have to disable the I/O APC checkbox on the Motherboard tab. I’ve found some guest OS crash with it checked, but if it works for you, then leave it as is. THEN, you need to add an obscure setting to the .vbox file associated with your VM image:
I found that tip about the UseRing0Runloop setting on a forum posting that I was lucky enough to stumble upon.
Performance/Stability
This is working for my setup. Running with these beta test level features does have a few downsides. The VirtualBox VM performance is noticeably slower running this way. It is also a little unstable and you will get intermittent guest OS crashing that you didn’t have before. That’s ok for me since I’m using this for development work so it’s easy enough to restart the VM when it happens. On the WSL side, version 2 is a big improvement. Anything that touches the filesystem is much, much faster. Then we have Docker support, of course, which is why I went through all this in the first place. Unfortunately, I am seeing that some base container images will crash on Docker. I’ve found Centos to be problematic, but Ubuntu works without a problem. Microsoft is still working on WSL2 and judging by the forums, container support is getting better.
This is most definitely not a good fit for most people, but for me, this is an improvement over my old setup. The instability is a little annoying at times. As of right now, January 2020, every component is still in development: Fast ring Insider version of Windows 10, beta version of WSL2, and experimental support for Hyper‑V in VirtualBox. With that said, I’ve been able to do things with Docker containers and WSL that were just not possible a few months ago—and I really like that.
I've written about WSL2 and it's glorious wonders many times. As its release (presumably) grows closer - as of this writing it's on Windows Insiders Slow and Fast - I wanted to update a few posts. I've blogged about a few cool thing around WSL and Docker
Here's a little HanselFAQ and some resources.
I want to run Linux on Windows
You can certainly use HyperV or VirtualBox and run a standard Virtual Machine. Download an ISO and mount it and run 'a square within a square.' It won't be seamlessly integrated within Windows - it'll be like the movie Inception - but it's time-tested.
Better yet, install WSL or WSL2. It'll take 5-10 minutes tops if your Windows 10 is somewhat up to date.
- How to install WSL on Windows 10
- WSL doesn't include a Linux kernel. Its Linux file system access is kinda slow, but it accesses Windows files super fast. If you use Cygwin, you'll love this, because it's really Linux, just the kernel is emulated.
- How to install WSL2 on Windows 10
- WSL2 ships an actual Linux kernel and its Linux file system is 5x-10x faster than WSL. WSL2 uses a tiny utility VM that expands contracts its memory and you can manage distros with the wsl command line.
- Do all your development work inside here, while still using VS Code on Windows. It's amazing. Watch me set up a friend with WSL2, LIVE on YouTube.
I want to SSH into Linux stuff from Windows
There's 15 years of websites telling you to install Putty but you might not need it. OpenSSH has been shipping in Windows 10 for over two years. You can add them with Windows Features, or if you like, grab a release and put it on your PATH.
You can also do things like set up keys to use Windows 10's built-in OpenSSH to automatically SSH into a remote Linux machine. I also like to setup Signed Git Commits with a YubiKey NEO and GPG and Keybase on Windows.
I need a better Terminal in Windows
The new Windows Terminal is for you. Download Windows Terminal now for free. It's open source. You can then run the Win64/Win32 ssh from above, or run any Linux distros SSH. Have fun. It's time.
NOTE: Have you already downloaded the Terminal, maybe a while back? Enough has changed that you should delete your profiles.json and start over.
You can download the Windows Terminal from the Microsoft Store or from the GitHub releases page. There's also an unofficial Chocolatey release. I recommend the Store version if possible.
My prompt and fonts are ugly
Make them pretty. You deserve the best. Go get Cascadia Code's CascadiaPL.ttf and PowerLine and buckle up buttercup. Get a nice theme and maybe a GIF background.
I want to use Docker on Windows and I want it to not suck
Surprise, it's actually awesome. You may have had some challenges with Docker a few years ago on Windows and gave up, but come back. There's been a huge (and fascinating) architecture of Docker on Windows. It's very nicely integrated if you have WSL2.
If you have WSL2 set up nicely, then get Docker Desktop WSL2. This version of Docker for Windows uses WSL2 as its engine allowing you to share your docker context across Windows and Linux on the same machine! As the maker intended! Download anydesk macbook download.
WSL 2 introduces a significant architectural change as it is a full Linux kernel built by Microsoft, allowing Linux containers to run natively without emulation. With Docker Desktop running on WSL 2, users can leverage Linux workspaces and avoid having to maintain both Linux and Windows build scripts.
So that means
Can Docker Run On Windows 10 Home
- Install Windows 10 Insider Preview build 19018 or higher
- Enable WSL 2 feature on Windows. For detailed instructions, refer to the Microsoft documentation.
- Download Docker Desktop Edge 2.1.6.0 or a later release.
Ensure your default WSL instances is WSL2. You can do that with wsl -l -v
, and then wsl --set-version <distro> 2

Then within Docker Desktop for Windows you've got two things to check. First, are you using WSL2 as your backend?

And then, the often missed setup, check under Resources | WSL Integration and tell Docker which WSL2 distros you want to use to access Docker. If you're paying attention you may notice that Docker Desktop tries to prompt you with a notification in Action Center but you might miss it.
NOTE: If you used an early Tech Preview, you might have an extra now-vestigial Docker context named 'wsl.' You want to use the Default one, not the WSL one.
This isn't intuitive or obvious and you might get weird errors like these
or
You can see if you have an extra context from before like below. That 'wsl' one is older (if you have it) and you want to use default in both Windows and WSL2.
I actually removed that one to avoid confusion with docker context rm wsl
.
Here's Ubuntu on my Windows machine
And here's my Windows machine. Note that docker images in both instances returns the same list. They are the same Docker backend!
I want to code in VS Code on Windows but compile on Linux
At this point once I've set things up I can go bananas. I can do Container-based development, where I use VS Code to run all my developer tools and builds insider a container..maybe I never event install Go or PHP or .NET Core. It's all just inside a container.
Oh, by the way, please Subscribe to my YouTube! I talk a lot about this stuff over there.
