How to setup Ngrok with a self-signed SSL cert

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.

Different Operating Systems

How to Run a Rails App in Production Locally
  1. Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
  2. bundle
  3. Run RAILS_ENV=production rake db:create db:migrate db:seed
  4. Run rake secret and copy the output
  5. From the command line: export SECRET_KEY_BASE=output-of-rake-secret
  6. To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
  7. Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
