Alpine Linux is a Linux distribution that uses musl, BusyBox, and OpenRC instead of glibc, GNU Core Utilities, and systemd, respectively.[2] [3] [4] [5] [6] This makes Alpine one of few Linux distributions not to be based on the latter.[7] For security, Alpine compiles all user-space binaries as position-independent executables with stack-smashing protection. Because of its small size and rapid startup, it is commonly used in containers providing quick boot-up times,[8] [9] on virtual machines (e.g., OS-level virtualization) as well as on real hardware in embedded devices, such as routers, servers and NAS.

History

Originally, Alpine Linux began as an embedded-first distribution for devices such as wireless routers, based on Gentoo Linux,[10] inspired by and the Bering-uClibc branch of the LEAF Project.[11] Founder Natanael Copa has said that the name was chosen as a backronym for "A Linux-Powered Network Engine" or some such similar phrase, but that the exact phrase has since been forgotten.[12]

Alpine's package management system, the Alpine Package Keeper (apk),[13] was originally a collection of shell scripts[14] but was later rewritten in C.[15]

In 2014, Alpine Linux switched from uClibc to musl as its C standard library.[16]

Derivatives

postmarketOS, a Linux distribution for mobile devices, is based on Alpine Linux.[17]
