Dockerfile

# git clone https://github.com/hexpm/hex.git
# cd hex
# git checkout v0.15.0
# # Add this Dockerfile in the dir
# docker build .
# # Then you can use the image as your base image to speedup your usage
FROM elixir:1.5.2

RUN HEX_MIRROR=https://hexpm.upyun.com mix local.rebar --force \
    # rebar3 update should be rerun if you add a new rebar dependence
    # or upgrade one, which is a little inconvenient
    && ~/.mix/rebar3 update

COPY . /tmp/hex

RUN cd /tmp/hex \
    && mix install \
    && cd \
