Managing a Kubernetes cluster can be tough for multiple reasons. What would you do, for example, if you mess something up and the entire cluster breaks? It’s everyone’s nightmare. You may think that doesn’t happen, but Spotify destroyed 2 out of 3 of their production clusters. They gave a great talk at KubeCon & CloudNativeCon EU about this.
So what if you end up in this situation? How would you solve it? Do you just start applying YAMLs you’ve hopefully stored somewhere on a brand new cluster? Are you sure you have all YAMLs and commands to get your cluster up and running the way it used to? Who knows what commands your team might have executed on the cluster while you weren’t looking…

The files in your repo are not a representation of the state of your cluster. Besides, how are you going to apply all these files? By hand? In what order?
Terraform
In comes Terraform. Terraform is a tool created by HashiCorp that allows us to predictably create…
