So you can download and install CBL-Mariner, the Linux distribution created by … Microsoft

Just a few months in the past we had been speaking to you, in passing, a couple of Linux distribution known as CBL-Mariner, which was for use by Microsoft to supply WSL2 with the graphical server Wanted to show graphical Linux purposes on our Linux desktop. CBL-Mariner already existed beforehand, and It had been utilized by Microsoft internally as a part of your cloud infrastructure.

However essentially the most related factor about that distribution is that, nicely … it had been created by Microsoft itself.. Sure, as you learn it: the corporate that created Home windows and that led a unclean conflict in opposition to free software program within the days of Gates and Ballmer, you may have now created and maintains your personal Linux distribution.

‘CBL’ stands for “Frequent Base Linux”

However issues get higher: you possibly can obtain and set up it in a digital machine. Learn on to learn how:

We’ve to generate our personal ISO file

The purpose is that, if we enter the CBL-Mariner repository, we’ll solely discover the supply code, however no ISO information that we are able to use to put in the working system. Does that imply we will not take a look at this ‘Microsoft Linux’? No method.

To generate the ISO from the out there code, we’ll want – first – to have Ubuntu 18.04, and set up a sequence of administration and improvement instruments, with the next command:

sudo apt set up make tar wget curl rpm qemu-utils golang-go genisoimage python-minimal bison gawk

As soon as that is completed, we should clone the aforementioned CBL-Mariner code repository on our pc. We’ll obtain this by coming into these instructions:

git clone

cd CBL-Mariner

git checkout 1.0-stable

As soon as our new native repository finishes syncing with the distant one, we’ll enter the folder and generate the bootable ISO picture:

cd toolkit

sudo make iso REBUILD_TOOLS=y REBUILD_PACKAGES=n CONFIG_FILE=./imageconfigs/full.json

As soon as this step is accomplished, we may have the ISO file out there at ../out/photographs/full/.

We’re going to set up Microsoft Linux

Now we are able to go to our favourite virtualization program (for instance, Oracle VM Virtualbox) and create a brand new digital machine through which we’ll set up CBL-Mariner utilizing the ISO file we now have. This digital machine should meet the next minimal necessities: 1 CPU, 1 GB of RAM and an eight GB disk (though it would not harm to double the RAM and disk area, if we are able to afford it):


As soon as the digital machine is created, we’ll right-click on it to open the ‘Configuration’ and we’ll instruct you to load the ISO at boot time:


Instantly after, we’ll begin the digital machine, we’ll select the choice ‘Graphical Installer’ and the set up course of itself will begin:

Cbl Instalacion1

On the primary display screen we are able to select between a minimal (‘Core’) and full (‘Full’) set up choice. CBL-Mariner does not embrace a lot software program, so both choice will develop into fairly quick (lower than a minute, typically).

Cbl Instalacion2

After that we should settle for the license of use, partition the laborious disk, select the ‘hostname’ and the username and password of the administrator. After that, CBL-Mariner will begin putting in packages (utilizing the RPM format utilized by distributions like Fedora). As soon as this step is completed, We’ll restart the machine and begin the session with the login knowledge that we selected earlier than.

Sure, though CBL-Mariner is the premise of the WSL graphical system, the distribution begins by default in textual content mode, no graphical interface.

Keep in mind that this isn’t a basic objective distribution (because the talked about Ubuntu and Fedora can be), however in an ultralight distribution, based mostly on a ‘default safety’ scheme and supposed to be used by Microsoft engineering groups engaged on Azure infrastructure.
