Say Hi To Microsoft's Own Linux: CBL-Mariner
Posted: 2021-07-16 19:50:00 Source: http://rss.slashdot.org/~r/Slashdot/slashdotLinuxatom/~3/F9RMygDzg3s/say-hi-to-microsofts-own-linux-cbl-mariner
An anonymous reader quotes a report from ZDNet, written by Steven J. Vaughan-Nichols: Microsoft now has its very own, honest-to-goodness general-purpose Linux distribution: Common Base Linux, (CBL)-Mariner. And, just like any Linux distro, you can download it and run it yourself. Microsoft didn't make a big fuss about releasing CBL-Mariner. It quietly released the code on GitHub and anyone can use it. Indeed, Juan Manuel Rey, a Microsoft Senior Program Manager for Azure VMware, recently published a guide on how to build an ISO CBL-Mariner image. Before this, if you were a Linux expert, with a spot of work you could run it, but now, thanks to Rey, anyone with a bit of Linux skill can do it. CBL-Mariner is not a Linux desktop. Like Azure Sphere, Microsoft's first specialized Linux distro, which is used for securing edge computing services, it's a server-side Linux. This Microsoft-branded Linux is an internal Linux distribution. It's meant for Microsoft's cloud infrastructure and edge products and services. Its main job is to provide a consistent Linux platform for these devices and services. Just like Fedora is to Red Hat, it keeps Microsoft on Linux's cutting edge. CBL-Mariner is built around the idea that you only need a small common core set of packages to address the needs of cloud and edge services. If you need more, CBL-Mariner also makes it easy to layer on additional packages on top of its common core. Once that's done, its simple build system easily enables you to create RPM packages from SPEC and source files. Or, you can also use it to create ISOs or Virtual hard disk (VHD) images. As you'd expect the basic CBL-Mariner is a very lightweight Linux. You can use it as a container or a container host. With its limited size also comes a minimal attack surface. This also makes it easy to deploy security patches to it via RPM. Its designers make a particular point of delivering the latest security patches and fixes to its users. For more about its security features see CBL-Mariner's GitHub security features list. Like any other Linux distro, CBL-Mariner is built on the shoulders of giants. Microsoft credits VMware's Photon OS Project, a secure Linux, The Fedora Project, Linux from Scratch -- a guide to building Linux from source, the OpenMamba distro, and, yes, even GNU and the Free Software Foundation (FSF). To try it for yourself, you'll build it on Ubuntu 18.04. Frankly, I'd be surprised if you couldn't build it on any Ubuntu Linux distro from 18.04 on up. I did it on my Ubuntu 20.04.2 desktop. You'll also need the latest version of the Go language and Docker.
