This commit reduce the final image size from 964MB to 272MB through:

  • Using multi-stage build
  • Remove unecessary files using .dockerignore file
  • Remove unecessary files after installing dependencies

before:
large_image

after:
reduced_2_image

For production, it is also possible to remove some files that it is not
necessary for it (like tests, uncompiled assets, etc) using the
to_remove argument, for example:

--build-arg to_remove="spec node_modules app/assets vendor/assets
lib/assets tmp/cache".

This reduce the final image to 164MB
