It is so easy, first get all interface exist in your Google compute engine, then follow code below:

const os = require('os');
const ip = require('ip');

// it gives you array of interfaces,
// you can pick the name of that interface you wanna get IP address
os.networkInterfaces(); 

ip.address("_interfaceName","ipv4") // you can now obtain the interface IP address you wanted.
