K3s Home Ops

Introduction

This repository contains the configurations for my home operations k3s cluster.

My applications are managed in GitOps fashion with ArgoCD, Renovate, and Github webhooks.

Cluster bootstrapping is performed with Techno-Tim's k3s-ansible repository, for which I contributed Cilium CNI support.

Background

I was running various self-hosted services in Docker and decided to learn Kubernetes and migrate my services to it in December 2023. Everything here has been built up from scratch since that time.
