# The added benefit is that Docker will cache this file and will not trigger
# the bundle install unless the Gemfile changed on the filesystem.

#       recent stable version of Docker.

# extra params that can be overriden via the command-line or docker-compose.yml

# In this case, we're prefixing everything with `bundle exec` so we don't have
# to do this every time we start the container or when running commands.
