Question about Droplets and private networks

Posted July 28, 2014

I have a web app running on DO now with a postgres backend. I’d like to setup a reporting server that will contain a replicated copy of the db. Can you explain to me, or provide an article how two droplets on my account communicate securely on your platform. Regards, Andy

So there are a few parts to this. First you need to enable private networking on your droplets:

Set Up And Use DigitalOcean Private Networking

Then, you need to get your PostgreSQL replication running:

Set Up Master Slave Replication on PostgreSQL

Finally, you need to set up a firewall so that the only connections allowed to the droplet with the replicated copy are via the private network:
