Kubernetes Manifests Repository

This repository contains Kubernetes manifest files for a comprehensive self-hosted platform running 40+ applications across various categories. This infrastructure was created for the migration from Docker to Kubernetes (K3S).

All applications are managed using GitOps principles with ArgoCD and utilize cert-manager for automated TLS certificate management.

Repository Structure

The repository is organized with one directory per application, containing all necessary Kubernetes resources:
