SSH Tunnels

What is it Used for?

Such tunnels are useful to test webhooks in local for example.
The client asks an HTTP proxy server to forward the TCP connection to the desired destination, meaning that you can expose your local web server through a public URL.



The procedure to create a tunnel is quite simple:
  1. 1.
    Install the Cloudflare utility on your machine: $ brew install cloudflare/cloudflare/cloudflared
  2. 2.
    Connect the utility to your cloudflare account with $ cloudflared tunnel login and choose the a domain that is not part of our infrastructure
  3. 3.
    Create a new tunnel in Cloudflare with $ cloudflared tunnel create <tunnel_name> (for ex cloudflared tunnel create overloop-developers-johndoe)
  4. 4.
    Add a new CNAME record to redirect the traffic to the tunnel: $ cloudflared tunnel route dns <tunnel_UUID> <cname> (for ex cloudflared tunnel route dns 0327bfe5-0d20-4e92-8496-08356d5cf660 johndoe to route the traffic to
  5. 5.
    Configure your tunnel in ~/.cloudflared/config.yml for example:
    url: http://localhost:3001
    tunnel: 0327bfe5-0d20-4e92-8496-08356d5cf660
    credentials-file: /Users/johndoe/.cloudflared/0327bfe5-0d20-4e92-8496-08356d5cf660.json
  6. 6.
    Start your tunnel $ cloudflared tunnel run <tunnel_UUID> (for ex: cloudflared tunnel run 0327bfe5-0d20-4e92-8496-08356d5cf660)
