    About Ngrok

ngrok allows for rapid tunneling, exposing local servers behind NATs and firewalls to the public internet over secure tunnels. More information in https://ngrok.com/
Installing ngrok

ngrok 1.x is unmaintained and its usage is not encouraged. Instead, follow the instructions on https://ngrok.com/download

download the zip file. In my case is for ubuntu_64 16.04

$ cd ~/Downloads
$ wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip


Unzip the file and get a binary file.

Using the recommended defaults

move the binary file to /usr/local/bin. Since this is in the $PATH defaults should now work.
Alias ngrok from .bashrc

You can put ngrok anywhere. An example folder is ngrok in my /home folder.
$ cd
$ mkdir ngrok && cd ngrok
$ cp $(ls ~/Downloads/ngrok*) ~/ngrok/
$ unzip ngrok-file.zip 

then make an alias in ~/.bashrc
$ echo "# ngrok alias" >> ~/.bashrc
$ echo "alias ngrok='full/path/to/ngrok/binary'" >> ~/.bashrc
$ . ~/.bashrc

You should be able to run ngrok from anywhere
$ ngrok --version
ngrok version 2.2.8

Using ngrok with Vagrant

Next step is getting an ngrok account and set identity keys locally. Check ngrok documentation after creating a new account.
From vagrant root, run vagrant share.  You should be getting something like
Vagrant Share now defaults to using the `ngrok` driver.
The `classic` driver has been deprecated.

For more information about the `ngrok` driver, please
refer to the documentation:

http://c23c2fce.ngrok.io is a random generated url and should be different each time. In my case I'm serving using apache defaults.
$ curl http://c23c2fce.ngrok.io
