- 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
![Provision](https://user-images.githubusercontent.com/27996771/122676008-2eb23600-d206-11eb-8275-fb5d99bc8515.jpg)
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 `./infra` layer:
- Create a Kubernetes [cluster](./infra/cluster.tf) using RKE
- Install some [Helm chart for bootstrap](./infra/bootstrap.tf)
- Build the `./apps` layer:
- Kustomize creates Argo [applications](./apps/resources)
- ArgoCD install those applications
Please visit the [Provisioning flow document](https://khuedoan.github.io/homelab/deployment/provisioning_flow.html) 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](https://khuedoan.github.io/homelab/deployment/hardware_requirements.html).
### 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](https://docs.docker.com/network/host/), 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
### Configurations
Change these configuration files to match your hardware and network setup:
- [Bare metal nodes settings](./metal/hosts.yml) (IP, MAC...)
- [OS settings](./metal/group_vars/all.yml) (PXE, network...)
### Build
Open the tools container:
```sh
make tools
```
Then build the homelab:
```sh
make
```
