+# Cloudflare Tunnel (Cloudflared)
+
+From your local docker devbox folder, run the following command to start the tunnel:
+
+```sh
+bin/run_cloudflared.sh <ip_or_dns_service:port_service>
+```
+
+Where `<ip_service>` is the ip or name of the service you want to expose. For example, to expose the `web` service, run:
+
+```sh
+bin/run_cloudflared.sh 172.16.250.10:80
+```
+
+See `IP_WEB_SERVER` to get the ip of the web server.
+
+**Remember!**
+
+If you want to expose a service running in your computer instead of a container, use the ip of your computer.
+The container do not read "localhost" because is running in a different network (in a container)
+
+Example: 
+```
+bin/run_cloudflared.sh 172.16.250.1:4321
+```
+
+See `IP_LOCAL_COMPUTER` to get the ip of the computer
