Using GitOps principals and workflow to manage a lightweight k3s cluster.



## :book:  Overview

![k3s Nodes](https://i.imgur.com/2hBUBi1.png)

This repository utilizes [Flux2](https://fluxcd.io/) to implement GitOps principals and define the state of my cluster using code.

## :computer:  Infrastructure

Setup for the individual nodes is now via NixOS and my [nixos-configuration](https://github.com/wrmilling/nixos-configuration) repository. Individual node names from the screenshot in [overview](#overview) can be searched for under the `hosts` directory of the aforementioned repo.

The current cluster consists of one (1) virtual master node, hosted on my TrueNAS Scale NAS, three (3) Minisforum UN100C mini-PCs, and one (1) BMax B4 Plus mini-PC. The mini-PCs double as both compute and ceph nodes.

## :gear:  Setup

Setup for Flux2, secrets, and the rest of the GitOps workflow can be found here under the [setup](setup/README.md) directory.
