Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general. -This variant is highly recommended when final image size being as small as possible is desired. The only caveat to note is that it does use [musl libc](http://www.musl-libc.org) instead of [glibc and friends](http://www.etalabs.net/compare_libcs.html), so certain software might run into issues depending on the depth of their libc requirements.
