Cloudflare Tunnel Setup on Linux

This quick guide will help you set up a Cloudflare Tunnel on your Linux server !

Cloudflare Tunnel provides you with a secure way to connect your resources to the web without a publicly routable IP address. With Tunnel, you do not send traffic to an external IP, instead, a lightweight daemon in your infrastructure (cloudflared) creates outbound-only connections to Cloudflare’s edge. Cloudflare Tunnel can connect HTTP web servers, SSH servers, remote desktops, and other protocols safely to Cloudflare. This way, your origins can serve traffic through Cloudflare without being vulnerable to attacks that bypass Cloudflare. (Source)

Getting Started

Pre-requisites

Configure XDebug, Visual Studio Code for a Vagrant VM

1. Assumptions

Project is served on /vagrant/craft in the Vagrant box
Guest machine IP is 10.0.2.2 (if this doesn't work, run route -nee in the VM and look for the gateway address)

2. Configuration

TLS secured TCP exposed Docker daemon on Dokku host - setup

Create certificates
Edit Docker options
Restart Docker
Copy client certificates from host
(optional) Add remote endpoint in Portainer

Tested on a standard $5/mo DigitalOcean VPS running Ubuntu 16.04.
