Cloudflare Tunnel in Docker: Hide Your Server From Everyone Except Cloudflare

Cloudflare has introduced a solution for securely exposing services without requiring a public IP, port forwarding, or reverse proxy. The company's Cloudflare Tunnel, also known as cloudflared, can be run using Docker in just five minutes. A Bash script is provided to simplify the process, utilizing the cloudflare/cloudflared:2025.11.1 image and authenticating with a Tunnel Token. The script runs a container named cloudflared, with the --restart unless-stopped flag ensuring continuous operation. By leveraging Cloudflare Tunnel, users can keep their servers private while allowing the company to handle public traffic. This solution is particularly significant in the context of cloud computing and cybersecurity, where secure exposure of services is a growing concern. As of November 2025, the cloudflared image version 2025.11.1 is available, demonstrating Cloudflare's commitment to regularly updating and improving its offerings. This development is expected to have implications for industries relying on secure and private server management.
