A Local Rails Server in a Local Network

I’m currently working on a Rails app, that I want to have available in my local network on the default port that Ruby on Rails uses: 3000.

To do that, I added a line to the development config (config/environments/development.rb):

config.hosts << 'hostname.local'

Update: Apparently adding the line config.hosts.clear works as well. Details about this are explained in the Rails Guides.

I started using Foreman to achieve this, and installed it using:

gem install foreman

Note that, according to a Wiki Page on Github, it’s not recommended to put foreman into the Gemfile.

Then I created a Procfile that Foreman uses to start the web server (which currently is the only process I need it to start):

web: bundle exec rails s -b 0.0.0.0 -p 3000

The -b 0.0.0.0 binds the process to that IP address and -p 3000 instructs it to use port 3000.

With that set up foreman start can be used to start a Rails server in development which is available in the local network.

This way I can check the layout and functionality on a mobile phone or one of my iPads.
