VhostGenerator

This gem outputs a general-purpose VirtualHost configuration file to run your web application behind an nginx or apache frontend.

The motivation of this gem is to automate that tedious task the first time, but also every time the virtualhost parameters (such as the number of instances to run and the ports where the instances are listening).

The gem features tries to integrate with the foreman gem by:

• reading configuration parameters from ENV (or from the .env file if invoked via foreman run)

Add this line to your application's Gemfile:

gem 'vhost_generator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install vhost_generator

Basic usage:

$ bundle exec vhost-generator -l 80 -s myapp.com -p 5000,5001,5002

Advanced usage: all command-line switches have their equivalent environment variables. See note in bundle exec vhost-generator --help.

$ SERVER_PORTS=80 SERVER_NAMES=myapp.com INSTANCE_PORTS=5000,5001,5002 bundle exec vhost-generator

More advanced usages: see features/ directory or run:

$ bundle exec vhost-generator --help

This gem also contains a wrapper to foreman export that will extract as many parameters from your foreman export command-line to make your generated virtualhost consistent with your Procfile, especially regarding the instance ports used.

$ bundle exec foreman-export-vhost --help

Pipe with sudo tee to save the configuration in your nginx sites-enabled directory.

$ bundle exec vhost-generator -l 80 -s myapp.com -p 5000,5001,5002 | sudo tee /etc/nginx/sites-enabled/myapp

Run through foreman run to leverage your application's .env (DRY and handy when having a configured RAILS_RELATIVE_URL_ROOT for example).

$ echo RAILS_RELATIVE_URL_ROOT='/myapp' >> .env
$ bundle exec foreman run vhost-generator -l 80 -s myapp.com -p 5000,5001,5002

Check the comment at top of each virtualhost configuration file for a command-line that can regenerate the file.
