 A [Docker][docker] image for [ngrok][ngrok] v2, introspected tunnels to localhost.
 It's based on the excellent work of [wizardapps/ngrok][wizardapps/ngrok] and [fnichol/ngrok][fnichol/ngrok].
 
 
 ## Features

-  * Safe: Runs as non-root user with a random UID `6737` (to avoid mapping to an existing UID).
-  * Simple: Just link as `http` or `https` in most cases, see below; exposes ngrok server 4040 port.
