How to whitelist rails webconsole for Docker
The webconsole of Rails is a very useful tool for debugging purpose.
If you use inside a docker container you cant use it for security/network reason.
If you want to use it again you have to add this simple line in your application.rb
if Rails.env.development? config.web_console.whitelisted_ips = ['172.16.0.0/12', '192.168.0.0/16'] end
