The Alpine team makes the claim that the minimalist installation is only 5MB; implying that it's for the distribution and comparing similar use-cases between Alpine and Ubuntu. With Alpine as the clear winner. If memory serves me there was a time when ubuntu offered a very light version of ubuntu. Something that was essentially kernel only plus a few vital tools.
In my development container the golang+debian container was about 800MB and the Alpine version is 426MB. I'm pretty sure that most of the bulk comes from the golang base image and my packages.

Furthermore this seems to be a direct attack on CoreOS, RancherOS and possibly a few mainstream tiny Linux distros.
One last thing. It's probably better to deploy a static binary instead of a 5MB guest.
