# Cloudflared Tunnel Often times it's useful to spin up a tunnel to your local machine to test out your application. Cloudflared is a great tool for this, and it's very easy to use with Docker. ## Usage The following command will start a tunnel to your local machine on port 3000: ```bash docker run --rm -p 3000:3000 cloudflare/cloudflared tunnel --url http://host.docker.internal:3000 docker run --rm cloudflare/cloudflared tunnel --url http://host.docker.internal:5173 ```
