Overview

Azure Linux is being developed by the Linux Systems Group at Microsoft for its edge network services and as part of its cloud infrastructure. The company uses it as the base Linux for containers in the Azure Stack HCI implementation of Azure Kubernetes Service. Microsoft also uses Azure Linux in Azure IoT Edge to run Linux workloads on Windows IoT, and as a backend distro to host the Weston compositor for WSLg.{{cite web |url=https://devblogs.microsoft.com/commandline/wslg-architecture/ |title=WSLg Architecture |last=Pronovost |first=Steve |date=April 19, 2021 |website=Windows Command Line |publisher=Microsoft |access-date=August 14, 2021}}

In a similar approach to Fedora CoreOS, Azure Linux only has the basic packages needed to support and run containers. Common Linux tools are used to add packages and manage security updates. Updates are offered either as RPM packages or as complete disk images that can be deployed as needed. Using RPM allows adding custom packages to a base Azure Linux image to support additional features and services as needed. Notable features include an iptables-based firewall, support for signed updates, and a hardened kernel.

Microsoft released the operating system in 2020. Its source code is available on GitHub, mainly under the MIT License, with some components under {{interlanguage link|Photon License|de|Photon OS}}, Apache License v2, GPLv2, and LGPLv2.1. Building Azure Linux requires the Go programming language, QEMU utilities, and RPM.

Starting from the release 2.0.20240301, Azure Linux was renamed from CBL-Mariner (Common Base Linux Mariner).{{cite web |url=https://www.phoronix.com/news/Microsoft-Azure-Linux |title=Microsoft Rebranding CBL-Mariner Linux Distribution To "Azure Linux" |author= |date=2024-03-05 |website= |publisher=Phoronix Media |access-date=2024-03-06 }}
