How do you export forwarded ports in Blink Build?

How to check if a container is running a service on a port? Can you expose a container service to the WireGuard interface over Build?

Ports on Build privately share between your Build instance and your device over a WireGuard interface. For this guide we’ll say we want to open remote ports 5000 to 5001. Here is what you'll need to troubleshoot if you are having problems with Build tunnels:

1. Double check that the container is in fact running the service on port 5000. Manually check that the service is running by using your preferred tool, curl, netstat, etc.
2. Then check if the port is exposed to the WireGuard interface inside the container. Make sure the 5000 service is looping on 0.0.0.0, which makes it accessible to the WireGuard interface. This is the most common problem. Note: This is not exposing it to the internet, only the WireGuard.
3. Reset all ports:
   a. build ports down.
   b. Remove the ports file, rm ~/.blink-build/.ports.json.
   c. Finally, add the ports again, build ports add tools 5000 5001.
