Deploy your app using just a single docker command without having to setup a reverse proxy nor a single port forwarding.
docker-cloudflared-tunnel is a Docker image based on Cloudflare Argo Tunnel solution which provide Cloudflare daemon ad-hoc capabilities through Docker.
According to the official Cloudflare documentation, Argo Tunnel is based on a lightweight daemon (cloudflared) running in your infrastructure that establishes outbound connections (Tunnels) between your service and the Cloudflare edge. When Cloudflare receives a request for your chosen hostname, it proxies the request through those connections to cloudflared. In turn, cloudflared proxies the request to your applications.
