Uses CentOS official base image and official binary
builds of Erlang, Elixir, and NodeJS.

For an example build file that cross-builds a Phoenix app, refer to phoenix/build-release.sh file.
This file should be placed at the root of the Elixir/Phoenix project and:
# Run the build script inside a container running this image
# Note: On Windows replace $(pwd) with the actual path
docker run -v $(pwd):/home --rm -it akalan/elixir-centos /home/build-release.sh
# Run the generated release inside the same container
docker run -v $(pwd):/home --rm -it akalan/elixir-centos /home/_build/prod/rel/appname/bin/appname
The release is tarred and zipped to releases/appname-version-utc_time_stamp.tar.gz
