`FROM debian:jessie` costs 53 MiB. (And by the way, please upgrade to Stretch at the earliest convenience.) `FROM alpine` costs 2 MiB. When you need to send container images across the globe on shitty connections, this matters a lot.

Actually, one of the first commands by default when container is run, is to fetch about 330Mb of compressed toolchain.

I didn't expect myself to ever say this, but: Our Openstack containers are much leaner than that. (Swift ends up at ~95 MiB for example.)
