# 2: We'll set the application path as the working directory
WORKDIR /usr/src/app

# 3: add the app's binaries path to $PATH:
ENV PATH=/usr/src/app/bin:$PATH

# 7: Install the current project gems - they can be safely changed later during
# development via `bundle install` or `bundle update`:
# ADD Gemfile* /usr/src/app/
# RUN set -ex && bundle install --jobs 2 --retry 3 --clean
