[SOLVED] Expose port on all interfaces using Webrick

Expose port on all interfaces using Webrick

I am new to Ruby.

I am working with a script that deploys a HTTPServer using WEBrick.

When the script runs, it logs out :

check_1  | [2018-12-20 17:51:47] INFO  WEBrick::HTTPServer#start: pid=1 port=4567

When I do a netstat on the machine, I notice that the service is listening only on 127.0.0.1

$ netstat -tulpn

root@c4a20aa7bd8c:/opt/service# netstat -tulpn
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.0.1:4567          0.0.0.0:*               LISTEN      1/ruby1.9.3

I want to listen on all the IPs so that I can communicate with this service from another container.

How or what configs will be necessary ?

My script definition for the server is :

#!/usr/bin/ruby


require 'rubygems'
require 'sinatra'
require 'sinatra/reloader' if development?
also_reload 'config.yml'
require "sinatra/config_file"
require 'mechanize'
require "json"
require 'open-uri'
require 'mongo'
require 'uri'
require 'addressable/uri'
require 'cgi'
include Mongo
require 'nokogiri'

set :server, 'webrick'

Solution

The answer you're looking for is in the Sinatra config docs: http://sinatrarb.com/configuration.html

Specifically the :bind option. Example: set :bind, '0.0.0.0'
