Debian still ships imagemagick6 in their repositories and I need imagemagick7
so this image is based on the ruby:latest with imagemagick7 compiled in.
FROM mfinelli/ruby-imagemagick:latest
WORKDIR /app
RUN apt-get update && apt-get install -y firefox-esr
COPY Gemfile* package*.json /app/
RUN \
bundle config set --local deployment true && \
bundle config set --local path vendor/bundle && \
bundle install && \
npm ci
COPY . /app
RUN npm run build
CMD bundle exec rspec
