Overview

ngrok allows you to expose a web server running on your local machine to the internet.

Read more about ngrok in the official docs.

Installation

  1. Go to your root directory
cd
  1. download ngrok .zip file
wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip

if by any chance the url has been changed go to ngrok download page and copy the url of the linux .zip file.

  1. unzip the file
unzip ngrok-stable-linux-amd64.zip

in case you don't have unzip installed, you can do that like this

sudo apt install unzip
  1. if you pass in this command ./ngrok you'll see this output
NAME:
   ngrok - tunnel local ports to public URLs and inspect traffic

DESCRIPTION:
    ngrok exposes local networked services behinds NATs and firewalls to the
    public internet over a secure tunnel. Share local websites, build/test
    webhook consumers and self-host personal services.
    Detailed help for each command is available with 'ngrok help <command>'.
    Open http://localhost:4040 for ngrok's web interface to inspect traffic.

EXAMPLES:
    ngrok http 80                    # secure public URL for port 80 web server
    ngrok http -subdomain=baz 8080   # port 8080 available at baz.ngrok.io
    ngrok http foo.dev:80            # tunnel to host:port instead of localhost
    ngrok tcp 22                     # tunnel arbitrary TCP traffic to port 22
    ngrok tls -hostname=foo.com 443  # TLS traffic for foo.com to port 443
    ngrok start foo bar baz          # start tunnels from the configuration file

VERSION:
   2.2.8

AUTHOR:

COMMANDS:
   authtoken    save authtoken to configuration file

  1. all you need to do is specify a port where your website is servered so that you expose it to the internet. Example
./ngrok http 8000

passing the above command will produce this output

Thanks for this.

I also had to add my authtoken configuration before i was able to serve my django app:

./ngrok authtoken your-auth-token

works like a charm 👍

optional: you can run ngrok instead of ./ngrok by running command below:

$ sudo cp /.ngrok /usr/bin/ngrok

it copies the ngrok folder to the binary folder /usr/bin - in return you have access to ngrok without the need to determine the path each time you call; you can confirm this by running command below

$ which ngrok

  3. ngrok config add-authtoken <token>
