## Set APP_HOME and BUNDLE_PATH as using ENV instructions:
ENV APP_HOME /usr/src/app/
ENV BUNDLE_PATH /gems
## Create both as directories to make sure they exist:
RUN mkdir -p ${APP_HOME}
RUN mkdir ${BUNDLE_PATH}
## Tell Docker to create volumes for our workspace and gems
## so other containers can access them.
RUN gem install bundler:2.1.4
WORKDIR ${APP_HOME}
## Create a Gemfile with just the Rails gem inside:
RUN echo -e "source 'https://rubygems.org'\ngem 'rails', '6.1.3.1'" > 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 . \
--database=postgresql \
--skip-bundle \
--skip-webpack-install
RUN bundle --jobs 4
RUN bundle exec rails webpacker:install
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/ .
