Alpine Linux - Wikipedia, the free encyclopedia
"Alpine Linux is a Linux distribution based on musl and BusyBox, primarily designed for "power users who appreciate security, simplicity and resource efficiency".
Size: the base system in Alpine Linux is designed to be only 4–5 MB in size (excluding the kernel). This allows very small Linux containers around 8 MB in size, while a minimal install to disk might be around 130 MB. The Linux kernel is much larger; the 3.18.16 kernel includes 121 MB of loadable kernel modules (primarily drivers) in addition to the 3.3 MB for the base x86-64 kernel image"
