In this series, I’ll first show you what Flux is and how it works, and later show you how to put all the basic Kubernetes configuration into a Git repository to add load balancer, ingress with cert-manager, and persistent storage with a single command.

The problem

In my previous articles, I demonstrated how to enhance my Raspberry Pi 4 cluster by incorporating various components such as MetalLB load balancer and Traefik with Cert-Manager. However, setting up each component individually can be a time-consuming and laborious process.

Especially when it comes to setting up a new cluster or restoring the old one.

The solution

The solution is to use a git-ops approach to install all components based on declarative configurations stored in git.

A project that leverages this approach is Flux.
