Quick setup with random URL

Use custom domain name

In some cases you want the tunnel to have a stable URL. Therefore Cloudflare offers the option to couple your domain name on which the funnel gets registered.

Authenticate with Cloudflare

Now we can create our first tunnel by running the following command.

cloudflared tunnel login

This will open a browser window and prompt you to log in to your Cloudflare account. After logging in to your account, select your hostname.

Create a tunnel and give it a name

cloudflared tunnel create mycoolapp

Confirm that the tunnel has been successfully created by running:

cloudflared tunnel list

Start routing traffic

Now assign a CNAME record that points traffic to your tunnel subdomain.

cloudflared tunnel route dns mycoolapp demo.yourdomain.me

Run the tunnel

Run the tunnel to proxy incoming traffic from the tunnel to any number of services running locally on your origin.
