Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox.
Alpine Linux is an independent, non-commercial, general purpose Linux distribution designed for power users who appreciate security, simplicity and resource efficiency. Mostly Alpine Used in Docker containerizing, Originally, Alpine Linux began as a very tiny Linux Distribution fork of the LEAF Project. The members of LEAF wanted to continue making a Linux distribution that could fit on a single floppy disk, whereas the Alpine Linux wished to include some more heavyweight packages such as Squid and Samba, as well as additional security features and a newer kernel. The concept behind Alpine was to create a light and simple firewall/proxy/VPN distro that could run in RAM.
Alpine uses its own package-management system, apk-tools, which originally was a collection of shell scripts but was later rewritten in C. Alpine currently contains most commonly used packages such as GNOME, Xfce, Firefox, and others.
Alpine Linux is built around musl libc and busybox. This makes it smaller and more resource efficient than traditional GNU/Linux distributions. 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.
Binary packages are thinned out and split, giving you even more control over what you install, which in turn keeps your environment as small and efficient as possible.
Alpine Linux is a very simple distribution that will try to stay out of your way. It uses its own package manager called apk, the OpenRC init system, script driven set-ups and that’s it! 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 will get in the way.
Alpine Linux was designed with security in mind. All userland 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.
The Alpine Linux project is pleased to announce the immediate availability of version 3.13.1 of its Alpine Linux operating system.
