This repository is a non-production (seriously don't use it in production) example of how to route traffic through a Cloudflare tunnel. It contains a docker compose specification for running:
- A single Cloudflare tunnel
- A Traefik Proxy instance to which the tunnel is routing exposed traefik with 3
- Three instances of a dummy service (whoami) which are proxied & load-balanced by Traefik.
- Create a tunnel in your Cloudflare account through https://one.dash.cloudflare.com//networks/tunnels.
- In the creation process, select
cloudflared(the utility we're using in Docker to create and operate the tunnel). - Select Docker in the installation process, you should have a token available from the command that's given for running
cloudflaredin Docker. - If you're prompted to provide a URL your tunnel should route to, it should be
http://proxy:80. - Copy/Paste the
.env.examplefile to.envand put your token there on the appropriate env variable. - In your Docker compose specification, replace
foo.barby the hostname you're running your tunnel under. docker compose up& 🎉. You should be set !
- On the domain routed to your tunnel, you should have access to Traefik routing to your three
whoamiinstances. Let's say I'm routing my tunnel fromtunnel.crossbone.cc, you can reachtunnel.crossbone.cc/whoami. - On your local machine, you can access Traefik's dashboard on http://127.0.0.1:8080/dashboard/.
If you have an issue you can just create an issue, I'll do my best to reply to it.
