sudo docker run -it --rm --name=cloudflared -v /root/.cloudflared:/home/nonroot/.cloudflared cloudflare/cloudflared:2022.2.0 tunnel create example-tunnel

3. Add DNS route internal.example.com to tunnel -> cloudflared tunnel route dns <tunnel-name> <route-hostname>

sudo docker run -it --rm --name=cloudflared -v /root/.cloudflared:/home/nonroot/.cloudflared cloudflare/cloudflared:2022.2.0 tunnel route dns example-tunnel internal.example.com

4. Add DNS route app1.example.com to tunnel -> cloudflared tunnel route dns <tunnel-name> <route-hostname>

sudo docker run -it --rm --name=cloudflared -v /root/.cloudflared:/home/nonroot/.cloudflared cloudflare/cloudflared:2022.2.0 tunnel route dns example-tunnel app1.example.com

5. Run tunnel in detached docker container -> cloudflared tunnel run
