Homelab

This project is a GitOps infrastructure framework designed for managing bare metal servers, container clusters, and networking. It serves as a declarative system for orchestrating the deployment and lifecycle of self-hosted services, using Git as the source of truth to synchronize the desired state of the environment.

The framework differentiates itself through a comprehensive automation suite that covers the entire hardware-to-service pipeline. It includes a PXE-based bare metal provisioner for network booting and operating system installation, alongside a lightweight container orchestration layer for managing clusters. Secure service exposure is handled via encrypted tunnels and automated SSL certificate issuance using the ACME protocol.

The project's capability surface extends to distributed block storage for resilient data access and centralized identity management for single sign-on across all hosted services. It also provides integrated secret management for secure credential distribution and tools for continuous integration, system monitoring, and automated volume backups.

The environment can be provisioned and managed via a command-line interface, which supports executing workflows across multiple nodes and simulating deployments in local sandboxes.
