# Install on Windows (Vagrant)

Developers can try out Kontain on Windows 10 Pro or above using any virtualization software that can run Linux with a modern Kernel version greater than 4.15. Below we show one of the easier ways to do this using Vagrant from HashiCorp software.

You need to have nested virtualization turned on in your BIOS to be able to install Vagrant.

You also need to turn on Hyper-V as Vagrant will use the built-in Hyper-V's virtualization capabilities.

To turn on Hyper-V virtualization in Windows, you may need to go to the Control Panel, and use the "Turn on Windows features". Please see the screenshots below.

To install the 64-bit version of Vagrant, you need to download it and install from here.

After installing Vagrant, we can now use it to run a Ubuntu 18.04 Linux VM.

To run a Vagrant VM, you need to first launch the Windows Command Prompt in Administrative mode as shown in the screenshot below:

Below we show the steps we use to run a Vagrant VM with Kontain on Windows:

C:\Users\user> mkdir kontain
C:\Users\user> cd kontain
C:\Users\user\kontain> curl -o VagrantFile  https://raw.githubusercontent.com/kontainapp/guide/main/_vagrantfiles/vagrantfile_win

# this initializes a Vagrantfile with the appropriate vm that gets auto-provisioned with Kontain
C:\Users\user\kontain> vagrant up
....

# a Vagrant VM is starts up with Kontain and docker pre-installed
# now you can ssh into it
C:\Users\user\kontain> vagrant ssh

# now that you are in the vagrant bash prompt. Let's switch to root
vagrant $ sudo -i

# run the kontain example to verify Kontain install
root # /opt/kontain/bin/km /opt/kontain/tests/hello_test.km Hello, Kontain!
Hello, world
Hello, argv[0] = '/opt/kontain/tests/hello_test.km'
Hello, argv[1] = 'Hello,'
Hello, argv[2] = 'Kontain!'

Hopefully, this gets you started on trying out Kontain on Windows and using Vagrant.

Please note that if you want to test out Kontain with docker-compose on Vagrant, please see the instructions in the Vagrantfile.

Here is the link to the Vagrantfile used to create a self-provisioning Vagrant VM with Kontain installed.
