Question: Image sizes about alpine-elixir

[bitwalker]

Well, they aren't empty :P, but I did some looking because they weren't that large in the past. Looks like things may have creeped up over time, I stripped some extra stuff now and the size for alpine-erlang is down to 76.2mb, and alpine-elixir is down to 98.1. Docker Hub shows them at about 45 and 55mb, respectively, which I assume is accounting for sharing layers.

The Elixir image builds on the Erlang image, which has a full Erlang installation in it, plus some associated tools required for building with NIFs, some required system libraries like OpenSSL. The Elixir image adds make, git, rebar, hex, plus the Elixir binaries/beams. Tools required only for building Erlang are stripped out during the image build.

I'm open to suggestions for reducing the image size further, but at this point I don't see any way to do so that doesn't compromise the general utility of the image. If you need really stripped down images, the only way to do that right is to build your own variant of this image which removes everything except what you need.
