Connecting to a digital ocean Private Network
I am building out an infrastructure for an application that my team is building. I currently have 4 droplets (may end up being 5 droplets) each running Ubuntu 16.04. I have one droplet acting as a reverse proxy server (running NGINX), one droplet acting as my Application server, one application acting as my Database Server and one droplet is a Continuous Integration server (running jenkins). I want to make sure that all but the reverse proxy server are only accessible over the Private network that you guys provide. How ever, I obviously still want to be able to access these droplets even though they are only accessible on private Networking. How could I do this? Do I need to setup openVPN and have that connect to the your Private Networking or what?
Thanks for your help!
