## What it is
Tofu Controller is a Kubernetes controller that reconciles OpenTofu and Terraform resources through Flux in a GitOps workflow. It supports full automation, hybrid, state enforcement, and drift detection models for managing infrastructure as code from Git.

## Use cases
- gitops terraform resources with flux
- run opentofu plan and apply from kubernetes
- detect terraform state drift automatically
- manage eks cluster provisioning via git
- enforce existing tfstate files declaratively
- multi-tenant terraform automation on kubernetes

## When to choose
- you already use Flux and want to manage Terraform/OpenTofu declaratively
- you need drift detection or state enforcement for existing tfstate files
- you want multi-tenant IaC automation inside Kubernetes

## When to avoid
- you don't use Kubernetes or Flux
- you prefer running Terraform directly in CI pipelines
- you need a standalone Terraform execution tool
