How can I run a python script in the Droplet A from Droplet B?

I currently have two Droplets that run Ubuntu 16. The first one, Droplet A, is the $5,00 super standard one where my website is built on. While Droplet B is the 80$ a month and has all the databases ready to be queried.

In both the droplets I have created a python backend. What I need is to be able to run a python script on the Droplet B from Droplet A.

How can I do that? This will be so helpful also in the future since we are planning to have many droplets communicating with each other.

There are many paths to doing this, but I’m happy to share mine. I’m a big bash fan, so this is far less fancy of a solution than others might use.

I created a bash script that I use to run commands across all of my servers, and it looks like this:

ssh root@otherserver $@

Let’s say I placed this script in /root named To run a command on “otherserver” I might just do this:

sh /root/ commandhere

The “$@” takes everything that follows and shoves it into the command, executed remotely over SSH.

A more professional way might be to expose your application to a network interface and then code in some form of authentication, or firewall it off, then make remote requests that are returned.
