Alpine Linux
What Alpine Linux is
Alpine Linux is a free, independent Linux distribution for power users who value security, simplicity and efficient use of resources. It is available for physical computers, Raspberry Pi devices, routers, servers, virtual machines, cloud images, containers and chroots. Its small footprint makes it suitable for constrained environments: a container requires no more than 8 MB, while a minimal disk installation needs around 130 MB of storage. Alpine is built on musl libc and BusyBox, with apk for package management and OpenRC for initialization. Its repository offers a broad package selection, split into binary packages so users can control what they install. Alpine says its userland binaries are compiled as Position Independent Executables with stack smashing protection, and its security tracker monitors issues using CVE, NVD and Alpine’s own security-fixes data.
Image choices include Standard, Extended, Netboot, Raspberry Pi, Mini root filesystem, Virtual, Generic U-Boot and Xen. Supported architectures vary by image and include aarch64, armhf, armv7, loongarch64, ppc64le, riscv64, s390x, x86 and x86_64. Standard is a minimal starting point requiring a network connection; Extended includes common packages, runs from RAM and is suited to routers and servers. The Virtual image is optimized for virtual systems, while Mini root filesystem targets containers and minimal chroots. The main repository is typically supported for two years; the community repository lasts until the next stable release.
Who it suits
Alpine Linux suits experienced Linux users seeking a compact distribution for physical systems, routers, servers, virtual machines or container environments. Its range of images and architectures also serves people deploying to Raspberry Pi, cloud images, chroots or Xen Dom0.
