Ref: about | Alpine Linux
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
and at Alpine Linux: The Lightweight Linux Distro Explained
Alpine Linux is a Linux distro that aims for minimalism, both in terms of space and in scope, as well as for higher security. The default installation media is only 133MB. This is quite impressive given that some ISO files on other distros are designed more for DVDs and thumb drives. Alpine fits comfortably on a CD-R with room to spare.
