This project is in ALPHA stage and this repository serves as a monorepo for my homelab and it's operated using gitops. This is a WIP project and should not be considered stable ¯\_(ツ)_/¯

The goal is to have a homelab operated by gitops. This applies to infrastructure, platform and services running on the platform. I will be running OKD as my K8S platform on top of Proxmox hypervisors.

The main goals are:

• A clustered Proxmox environment where I can deploy an OKD environment.
• Using Gitops for continuous deployment and self-documenting deployments.
• Easy and fast error recovery of services.

My personal goals are:

• Learn and understand how K8S works.
• Learn how to use gitops as a way to deploy and operate both hypervisors and services.

OKD is the community version of OpenShift. It is a Kubernetes distribution with a lot of features on top of Kubernetes. Installing a user-provisioned cluster on bare metal serves as a guide for the installation of OKD on top of Proxmox hypervisors.

Proxmox Hypervisors consists of four (4) Lenovo P330 ThinkStations. Each node has the following specs:

• CPU: i7-8700t
• RAM: 64GB DDR4
• Storage: 250gb NVMe for OS and 2tb NVMe for storage
• Network: 1Gbe NIC (onboard). Will be upgraded to 10Gbit SFP+ NIC in the future.

It is a simple network setup with a Mikrotik router. The network is segmented into two subnets. One for the hypervisors and one for the OKD platform.

• DNS: Pi-Hole + OKD Service node
• Router: Mikrotik
• IP-Subnet for hypervisors: 192.168.10.0/24
• IP-subnet for OKD platform: 192.168.11.0/24

The Proxmox hypervisors

OKD is deployed using the platform-agnostic installation method.

OKD requires a minimum of 3 control-plane nodes and 2 compute nodes. Each node requires a minimum of 16GB of RAM and 4 vCPUs. This is the minimum requirement for a small cluster.

There are to types of backup strategy in place:

• ETCD - gardener/tcd-backup-restore.
• Volumes - Kasten K10
