Project: Terraform Swarm mode cluster
Using Terraform to provision a swarm cluster on DigitalOcean

I recently started playing around with Terraform. Since I often manually spin up a couple of droplets on DigitalOcean to set up a Swarm mode cluster to try out some projects or set ups, I figured I should put all of that into code as my first Terraform project. I created a Terraform module for provisioning a basic Swarm mode cluster during this project. Ideal for labs or development clusters.
