My Own Cloud
... managed with Flux, Renovate and GitHub Actions
🍼 Overview
This educational project is designed to provide a hands-on learning experience for mastering Kubernetes cluster configurations and best practices. The repository showcases a declarative implementation of a Kubernetes cluster, following GitOps principles that can be utilized with a variety of tools and workflows.
The main goal of this project is to demonstrate best practices for implementing enterprise-grade security, observability, and comprehensive cluster configuration management using GitOps in a Kubernetes environment, while fostering learning and growth in the Kubernetes community.
This repository leverages a range of cutting-edge open-source tools and platforms, forming a comprehensive technology stack that demonstrates the power of the CNCF ecosystem.

☁️ Cloud Services
Although I manage most of my infrastructure and workloads on my own, there are specific components of my setup that rely on cloud services.
| Service | Description | Cost (AUD) |
|---|
| Cloudflare | I use Cloudflare in my home network for DNS management and to secure my domain with Cloudflare's services. | ~$69/yr |
| GCP | I use Google Cloud Platform (GCP) to manage backups using Google Cloud Storage (GCS) and employ GCP's OAuth for authentication. | ~20/yr |
| GitHub | I use GitHub for code management and version control, enabling seamless collaboration in addition to OAuth for authentication | Free |
| Lets Encrypt | I use Let's Encrypt to generate certificates for secure communication within my network. | Free |
| | Total: ~$35/mo |
🖥️ Technology Stack
The below showcases the collection of open-source solutions currently implemented in the cluster. Each of these components has been meticulously documented, and their deployment is managed using FluxCD, which adheres to GitOps principles.
The Cloud Native Computing Foundation (CNCF) has played a crucial role in the development and popularization of many of these tools, driving the adoption of cloud-native technologies and enabling projects like this one to thrive.
