Rails: Using SSL in locale development

1. Generate a new certificate:

  
    # Create a folder to store the certificates
    mkdir config/certs
    # Ignore the certificates folder to avoid accidentally commiting the certs to the repo
    echo "config/certs/*" >> .gitignore
    # generate the certificate:
    # Be sure to set the domain name to "lvh.me". Other settings don't matter
    openssl req -x509 -sha256 -nodes -newkey rsa:2048 -days 365 -keyout config/certs/lvh.me.key -out config/certs/lvh.me.crt
  

1. Configure rails to optionally force ssl in development mode:

  
    Rails.application.configure do
      config.force_ssl = true if ENV.fetch('SSL', nil) == "true"
    end
  

1. Start the server in SSL mode:

  
    SSL=true bundle exec rails s -b 'ssl://0.0.0.0:3000?key=./config/certs/lvh.me.key&cert=./config/certs/lvh.me.crt'
  

1. Access the page:

  
    https://lvh.me:3000/
