## Make sure we have yarn properly sourced:
RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
RUN echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list

## Update OS and download yarm from source specified above:
RUN apt-get update -qq && apt-get install -y build-essential git nodejs yarn

## Set up our workspace directories:
ENV APP_HOME /usr/src/app/
RUN mkdir ${APP_HOME}

## Tell bundler where to store downloaded gems:
ENV BUNDLE_PATH /gems
RUN mkdir ${BUNDLE_PATH}

## Tell Docker to create volumes for our workspace and gems
## so other containers can access them.
VOLUME ${APP_HOME}
VOLUME ${BUNDLE_PATH}

## Switch to the the work directory from container root:
WORKDIR ${APP_HOME}

## Create a Gemfile with just the Rails gem inside:
RUN echo "source 'https://rubygems.org'\ngem 'rails'" > Gemfile

## Bundle to install rails:
RUN bundle install

## Use Rails to generate a new app. We'll configure it later.
RUN bundle exec rails new . 

## setup yarn for rails:
RUN bundle exec rails yarn:install


## Tell docker not to create a layer:
FROM scratch AS export-stage

## Copy the generated files onto the host. Note that because we are in a  
## new container, we don't have access to the previous ${APP_HOME} 
## variable and so we must hard code it as our source:
COPY --from=builder /usr/src/app/ .
