Alpine – small, simple and secure Linux distribution

Alpine Linux is an independent, non-commercial, general purpose Linux distribution.

Alpine Linux is built around musl, libc OpenRC, and BusyBox in replace of glibc, GNU Core Utilities, and systemd. This makes it small and very resource efficient. A container requires no more than 8 MB and a minimal installation to disk requires around 130 MB of storage. Not only do you get a fully-fledged Linux environment but a large selection of packages from the repository.

It uses its own package manager called apk, the OpenRC init system, and script driven set-ups. This provides you with a simple, crystal-clear Linux environment without all the noise. You can then add on top of that just the packages you need for your project, so whether it’s building a home PVR, or an iSCSI storage controller, a wafer-thin mail server container, or a rock-solid embedded switch, nothing else gets in the way.

Alpine Linux was designed with security in mind. All user-space binaries are compiled as Position Independent Executables (PIE) with stack-smashing protection. These proactive security features prevent exploitation of entire classes of zero-day and other vulnerabilities.

It’s a base system for many enterprise routers, and used in embedded devices.
