Homelab

! ⚠️ WORK IN PROGRESS

Hardware

4 nodes of NEC SFF PC-MK26ECZDR (Japanese version of the ThinkCentre M700):
- CPU: Intel Core i5-6600T @ 2.70GHz
- RAM: 16GB
- SSD: 128GB
TP-Link TL-SG108 switch:
- Ports: 8
- Speed: 1000Mbps

Overview

A single make command will automatically:

Build the ./metal layer:
- Create an ephemeral, stateless PXE server
- Install Linux on all servers in parallel
Build the ./cluster layer:
- Create a Kubernetes cluster using RKE
- Install some Helm chart for bootstrap
Build the ./apps layer:
- Kustomize creates Argo applications
- ArgoCD install those applications

Please visit the Provisioning flow document to learn more.

Get Started

Harware requirements

Any modern x86_64 computer(s) should work, you can use old PCs, laptops or servers. A total of 3 or more nodes is recommended for high availability.

To view the detailed requirements, please visit the Hareware requirements document.

Prerequisite

For the controller (your laptop or desktop):

SSH keys in ~/.ssh/{id_ed25519,id_ed25519.pub} (you can generate it with ssh-keygen -t ed25519)
Docker with host networking driver (which means only Docker on Linux hosts, you can use a Linux virtual machine with bridged networking if you're on macOS or Windows)

For bare metal nodes:

PXE IPv4 enabled
Wake-on-LAN enabled and boot to network mode by default if turned on via Wake-on-LAN
Secure boot disabled (optional, depending on the OS)
Note their MAC addresses

To view the detailed instruction, please visit the Prerequisite document.

Configurations

Change these configuration files to match your hardware and network setup:

Bare metal nodes settings (IP, MAC...)
OS settings (PXE, network...)

To view the detailed instruction, please visit the Configuration document.

Build

You can install all the tools manually, or you can use the convenience tools container:

make tools

Then build the homelab:

make
