docker-compose.dev.yml

# This docker-compose file sets up the dev environment.
# It builds an app container based on Dockerfile.chemotion.dev
#
# USAGE:
# - Run app server: docker-compose -f docker-compose.dev.yml up
# - Initial dev setup without external seeds: docker-compose -f docker-compose.dev.yml run app bundle exec rake db:setup
# - Open shell within container (for rake tasks etc): docker-compose -f docker-compose.dev.yml run app /bin/bash
# - Run unit tests: docker-compose -f docker-compose.dev.yml run app bundle exec rspec --exclude-pattern spec/{features}/**/*_spec.rb
# - Run feature tests: docker-compose -f docker-compose.dev.yml run app bundle exec rspec spec/features
# - Run JS tests: docker-compose -f docker-compose.dev.yml run app npm test
# Note: all these commands can be run manually from the shell. This might be the better choice as docker creates an overlay FS for every run
