This is used as docker base image for Erlang OTP. The goal is to provide images for a few last erlang releases (currently 19 / 18 / 17), in close to full feature Erlang OTP, and relatively slim images. Support to R16 and R15 are provided in this repo on a best-effort basis, and not part of official-image effort in docker-library/official-images#1075 .
here is providing a latest Erlang 19-rc1 image, but since master branch is moving fast, official release will be in June 2016; here is not going to push to official-images but you can clone this project and build it locally:
$ docker build -t erlang:19.0-rc1 19/
[...]
➸ docker run -it --rm erlang:19.0-rc1
Erlang/OTP 19 [erts-8.0] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false]

- the standard variant
erlang:18,erlang:17, builds from source code, based on buildpack-deps:jessie; it covered gcc compiler and some popular -dev packages, for those erlang port drivers written in C; while it doesn't have java compiler so jinterface doesn't compile, wxwidgets depends on some gl/gtk headers/lib also doesn't compile; I assume to run GUI applications in docker is not popular, so here we can save some space; jinterface is similar, the java dependencies are too fat, I assume demand to write java code for erlang applications is low; - the -onbuild variant for each erlang version, to utilize ONBUILD instruction from Dockerfile, those are for starters
- the slim version is built from
debian:jessieinstall building tools (compilers & -dev packages) on the fly and uninstall after compilation finished, to shrink image size; - rebar and rebar3 tool is bundled in
erlang:18image, for-onbuildimages to do something interesting; - the
erlang:19images are built from current master branch of erlang/otp, there is no tag yet, so build it from tags like erlang/otp@e038cbe ; will be ready to build official 19 images when 19 is released in March.
