My approach to Kubernetes installation & management on bare metal

Installation

• x86_64:
  • CoreOS (now Flatcar Container Linux) as a Linux distro
  • Kubespray as a Kubernetes installer
  • Metallb and NGINX Ingress Controller for incoming traffic
• arm (Raspberry PI 3B)
  • HypriotOS as a lightweight container-oriented Debian-based Linux
  • k3s as a lightweight Kubernetes distribution with sqlite instead of etcd
  • Metallb and Traefik v1 for incoming traffic

Configuration

• Pulumi for everything except Helm charts
• Helmsman for Helm charts
• kubie for using multiple Kubernetes contexts simultaneously in different terminals
