# This docker image builds specific version of erlang on Ubuntu. Erlang official releases are few versions behind and
# building from source is the only way to get latest.
# Also, you don't want to install bunch of packages on your host system simply to compile. Once this image is built
# and container is run, you can simply copy /opt/erlang to your host's /opt/erlang and run erlang from there.

# docker build -t erlang:27 -f erlang.dockerfile .
# docker run --rm --name erlang -d -v /home/daisy/projects/erlang:/erlang -t erlang:27
# docker exec -it erlang bash
# Alternately, copy final built artifacts:  `docker cp erlang:/opt/erlang /opt`
#  Note that it must be copied to hosts /opt/erlang since this path is hardcoded in the artifacts
