# Binaries are available in the container:
# Get the image ID: % docker images
# Start a container: % docker run -t -i <imageid> /bin/bash
# Get the container ID: % docker ps
# % docker cp <containerid>:/usr/local/bin/constellation-node .
# % docker cp <containerid>:/usr/local/bin/constellation-enclave-keygen .
#
# Keep the image, restart it and check out constellation from Github to quickly
# recompile later on (without recompiling dependencies):
# % cd /usr/local/src && rm -rf constellation
# % git clone git@github.com:jpmorganchase/constellation.git && cd constellation
# (or use 'docker cp' to copy your local repository.)
#
# Just remember to run stack with these options:
# % stack install --local-bin-path /usr/local/bin --test --ghc-options '-optl-static -fPIC'
