How to make Sinatra listen on two ports with socat

I had a classical Sinatra application which was accessible on two ports. After migrating it to modular style the second port is not working anymore.

My initial implementation was:

require 'sinatra'

set :port, 8080
set :bind, '0.0.0.0'

----some routes-----
...

The resulting implementation was:

require 'sinatra/base'
require_rel 'lib'

class MyApp < Sinatra::Base

  register Sinatra::SomeRegister
  helpers Sinatra::SomeHelper

set :port, 8080
set :bind, '0.0.0.0'

----some routes-----
...
run!
end

The application is run using:

socat tcp-l:8181,fork,reuseaddr tcp:localhost:8080 &
ruby /path/my_app.rb

The application doesn't respond on port 8181 anymore.

Solution

  • The fix was to install socat first:

    apt-get update && apt-get --allow-unauthenticated -y install socat
