Running Mod_Perl with Mojolicious in Docker

  FROM motemen/mod_perl:5.36.0-2.4.58-2.0.13
  # Run apt first, so layers can be reused if the image is built often, do not include package lists
  RUN apt-get update -y && apt-get install -y wget make build-essential \
      && rm -rf /var/lib/apt/lists/*
  # Installing modules/packages might also be done in the beginning (as long as they don't need other files in place)
  # If you ever need something like package.json/pom.xml/Gemfile/requirements.txt etc., COPY those first)
  RUN cpan -iT Plack Mojolicious
  # Bigger dependencies that change less frequently can go first, for caching
  COPY lib /usr/local/apache2/lib
  # The rest of the configuration and app files

(probably not super important unless you're doing a lot of stuff, but sometimes useful)
