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

Infrastructure

I've used Techno Tim's k3s-ansible playbook to deploy a 3 node (1 master & 2 workers) cluster on 3 Proxmox VMs.

Servers

1. Proxmox

Description	Spec
Server	Acer Nitro 5
RAM	16GB
CPU	Intel i7 11th gen
HDD	1TB
SSD	256GB

2. TrueNAS Scale

Description	Spec
Server	SONY VAIO - SVE14126CXB (2012)
RAM	8GB (maxed out)
CPU	Intel i5-3210M
SSD (os)	256GB
SDD	1TB

Proxmox & Truenas(bottom) servers

Setting it up

1. Create flux namespace and the necessary sops secret

export SOPS_AGE_KEY_FILE='<path-to-key.txt>'

make bootstrap0

2. Flux installation

export GITHUB_TOKEN='ghp_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'

make bootstrap

Requirements

• sops (secrets management)
• age (encryption)
• precommit
