Quickly Set Up Guacamole Using Docker

Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH.

Thanks to HTML5, once Guacamole is installed on a server, all you need to access your desktops is a web browser.

The Guacamole manual can be found here, but because the project is broken into 2 or more peices, it can take a bit of poking around and toggling between sections to find the exact steps one needs to quickly get up and running from scratch using Docker.
