Extract Cloudflare WARP Connector WireGuard configuration.

Cloudflare WARP is an overlay network like ZeroTier and Tailscale but instead of peer-to-peer, you connect to the nearest Cloudflare PoP using WireGuard.
Finally, a free site-to-site VPN from Cloudflare.

This program uses the warp-cli Linux client, installs it inside the Docker container, register WARP Connector with the token, and then extract the configuration file.

1. Create a tunnel in Cloudflare Zero Trust dashboard with WARP Connector as tunnel type.
2. Copy the generated WARP Connector token starting with eyJhIjoi and paste it as argument <token> in Docker.
3. It will output wgcf-connector-<registration_id>.conf file in your current working directory, which you can use in WireGuard.

docker run --rm -v $(pwd):/app/output ghcr.io/animmouse/wgcf-connector <token>

docker build -t wgcf-connector .
docker run --rm -v $(pwd):/app/output wgcf-connector <token>
