## Description

This project is a Terraform Kubernetes provisioner and K3s cluster deployer designed to automate the installation and configuration of lightweight container orchestration on Hetzner Cloud infrastructure. It functions as a Hetzner Cloud infrastructure module, using declarative configuration to manage the full lifecycle of virtual machines, private networks, and load balancers.

The orchestrator focuses on high availability by deploying redundant control planes and worker nodes across multiple physical data centers to ensure service continuity. It incorporates a cloud network security manager to implement dual-stack private networking and perimeter firewall rules that restrict traffic to specific ports and protocols.

The project covers broader infrastructure capabilities including block-storage volume attachment for data persistence, cattle-based node scaling to adjust resource capacity, and the generation of system manifests using HCL templates. It also handles the provisioning of load balancers to route external traffic to internal services.
