Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user

1. Go to the metron-config folder.

$ cd metron/metron-interface/metron-config

2. Run the maven build taks

It creates a new build from the metron config UI with Maven and compresses it in a tar file. Once it's finished, you can find this file in the metron/metron-interface/metron-config/target folder. Suppose it's metron-config-0.7.1-archive.tar.gz.

/**
 * Usage of async function you want to call recursively:
 *
 * 1. We're responsible for resolving our own promise in the recursive async func.
 * 2. We would like to execute other commands after the invoncation of the recursive func (line #32).
 *
 * Since we're creating a brand new promise in the function body, if we want to execute other code after the initial
 * recursive call, it's important to resolve the first promise when you want to exit the recursion. Otherwise, the code after 
 * the first call (line #32) won't be executed at all.
