About this Repo

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 .

use the Erlang 19

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]

Eshell V8.0  (abort with ^G)
1> erlang:system_info(otp_release).
2> uptime().
6 seconds
3> os:getenv().

Read the release annoucement


  1. 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;
  2. the -onbuild variant for each erlang version, to utilize ONBUILD instruction from Dockerfile, those are for starters
  3. the slim version is built from debian:jessie install building tools (compilers & -dev packages) on the fly and uninstall after compilation finished, to shrink image size;
  4. rebar and rebar3 tool is bundled in erlang:18 image, for -onbuild images to do something interesting;
  5. the erlang:19 images 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.

The official release has 52 libs, while here by default it provided 51 of them, except jinterface, because to build that one would pull all jdk dependencies and make this image too fat, it's just avoided here; if you really need that to write code in java and interface into erlang code, you may create an issue for this project.
