tf2helm

t2helm is a simple Python utility that converts a Terraform module to a Helm Chart. The Helm Chart contains a Kubernetes Custom Resource understood and managed by the Terraform Operator at present and it will soon be extended to support other similar operators e.g. oam-dev Terraform Controller.

tf2helm reads a Terraform module from a local or remote path and converts it into a Helm chart in a specified directory. It reads the Terraform variables and writes them as .Values.required and .Values.optional values in the Helm values.yaml file depending on whether they have been assigned values or not.

This gives infrastructure operators e.g. DevOps or Platform engineers the flexibility to set sensible default parameters for cloud resources and make them visible and configurable to application developers who may or may not override them afterwards.
