How can I setup a local SSL certificate and a Rails application?

Question

This might be a two-in-one question.

1. I have a Rails application for home/hobby usage, hosted on a Raspberry Pi and I was wondering if it's possible to create a local SSL certificate for it and setup Rails to use it?

2. If yes, how can I setup my Rails/Puma/Foreman/Ubuntu application? For now, I am running the application with Foreman, by using a Procfile:

   web: bundle exec puma -t 8:8 -p 3000
   worker: bundle exec sidekiq
   clock: bundle exec clockwork config/clock.rb
   

Answer 1

1. Yes you can. Here is a gist explaining the process:

2. My procfile contains an entry that looks like this:

   server: rails server puma -b 'ssl://0.0.0.0:3000?key=server.key&cert=server.crt'

This seems to work for me. I also set

config.force_ssl = true 

in config/application.rb

I gathered info about it from all these places:
