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.
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OS question has been asked and answered so many times over the years that search results are flooded with the same outdated answer: No, you can’t have both.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.
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.
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.
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.
Do you want to install Docker on Windows 10/8/7 or server without enabling the Hyper-V (Hypervisor Platform)? Then here is the tutorial, the easiest way to start a Docker container on Windows…
Docker, an open-source platform offers containerized virtual machines to run various apps and operating systems in an isolated environment. As compared to other virtual machines software, the Docker is lightweight, and images on it use the system’s kernel to provide optimized speed. Moreover, the images meant to run on it are also stripped down or very light, for example, Ubuntu Image which is far small in size and lighter as compared to regular Ubuntu server CLI ISO available online to download and use.
In terms of version, Docker offers two editions one is Enterprise and the other community that is open-source software. Although the open-source which is free to use has all the functions required to operate containers and can be used on servers and on development to test machines; the things which make it different from the Enterprise version are the support and some management functions to also use them in productive operations.
So, if you don’t want to enable Hyper-V in order to preserve Virtualization support to other software such as VirtualBox or Vmware workstation player then here is the simple way to install Docker-CE on Windows 10 or 7 using the Docker ToolBox.
What we learn here:
The first thing we need is the ToolBox, a package that contains various tools that are: Docker, Docker-machine, docker-compose, Kitematic Web-based GUI, and VirtualBox. You can see that VirtualBox is there, thus in the Docker ToolBox instead of Hyper-V, it will use that to run the base Linux image to create further containerized machines. The Toolbox is available for both macOS and Windows 10/8/7 platforms, here is the Github page to download the executable binaries.
Once you have the installer using the above link, simply run it like any other Windows software. You will see the “Docker Toolbox Setup Wizard“. Click on the Next button.
By default like any other Windows application, the wizard will also install the Docker files and folder in the C: Drive. However, if you want to save it in some other directory then select that, here.
The benefit of using the ToolBox is it comes with all the essential components we need for using the Docker including the Graphical user interface app called Kitematic to graphically install, start, stop, and delete Docker images pulled from Docker Hub. By default, all of them will be selected and it is recommended to let them as it is, however, if you are an advanced user then select accordingly.
To create various virtual containers the Docker uses a lightweight Linux distro and to run without Hyper-V it uses VirtualBox. Thus, leave the default options such as Upgrade Boot2Docker VM, Binaries to Path as it is, and click on the Next button.
Finally, after installing everything you will see an icon on your Desktop- Docker Quickstart Terminal, double click on that to start the Bash terminal for setting up the Docker Virtual Machine image on VirtualBox.
Either you can use the same terminal window or open the Command prompt to check whether the Docker is working fine or not. On the Terminal type:
The above command will fetch the latest Docker image of Ubuntu from Docker Hub.
Start the Ubuntu container
One the image is pulled, run that as a container:
You will see the Ubuntu bash with root user, simply start running all the commands you generally run on Ubuntu Linux OS.
In case you don’t want to use the command-line interface, then there will be another icon on your Desktop with the label “Kitematic (Alpha)” double click that to run. Select the VirtualBox option from its interface. You will see all the running containers on your system including the recommend images.
You can directly execute commands from the interface of Kitematic to your installed and selected container via PowerShell. Just select the container and click on the Exec option given on the menu. This will open the PowerShell to run container supported commands.
In this way, we can easily get all the benefits of Docker but without enabling Hyper-V on our Windows system. You can also install Docker ToolBox using the Chocolatey...
