How does Kubernetes work with Terraform?
The biggest benefit when using Terraform to maintain Kubernetes resources is integration into the Terraform plan/apply life-cycle. So you can review planned changes before applying them. Also, using kubectl , purging of resources from the cluster is not trivial without manual intervention. Terraform does this reliably.

How to deploy nginx on Kubernetes using terraform?
In this tutorial, you will learn how to interact with Kubernetes using Terraform, by scheduling and exposing a NGINX deployment on a Kubernetes cluster.
