This document summarizes Terraform and how it can be used to manage Kubernetes. It discusses what Terraform is, how it compares to other configuration management tools, its core components like resources and providers, and challenges like some Kubernetes resources not yet being supported. It concludes by noting the Kubernetes provider is new but will mature over time.
