Spin up a bare metal cluster in 2022

1. k3os

   1 26 3,489 0.0 Go

   Discontinued Purpose-built OS for Kubernetes, fully managed by Kubernetes.

   

   I (still) run k3os, but it's dead since SUSE bought rancher. (see https://github.com/rancher/k3os/issues/846)

3. kairos

   2 23 1,296 9.7 Go

   The immutable Linux meta-distribution for edge Kubernetes.

   

   A bit biased maybe, as I'm the Kairos creator, but I'd really suggest to check it out. https://github.com/kairos-io/kairos is an Immutable OS that have quite a different approach, avoiding configuration management and infrastructure drifting by having real single-image, atomic upgrades and lastly cloud-init driven. The OS is treated like an app, where you just deploy and upgrade to a certain specific version (no single packages, no transactional upgrades - atomic OTA swaps)

4. rke2-ansible

   3 3 261 5.8 HCL

   RKE2 cluster provisioning via Ansible.

   

   I have had success with RKE2 and the corresponding Ansible playbook: https://github.com/rancherfederal/rke2-ansible

5. k3s-ansible

   4 32 2,300 7.3 YAML

   

   Plus there is a pretty good ansible playbook https://github.com/k3s-io/k3s-ansible

6. kubespray

   5 60 16,978 9.8 Jinja

   Deploy a Production Ready Kubernetes Cluster

   

7. k3sup

   6 58 6,593 5.2 Go

   bootstrap K3s over SSH in < 60s 🚀

   

   Personal preference, Terraform the relevant Ubuntu VM's (spec according to requirements) and then use K3 sup (https://github.com/alexellis/k3sup) and remove klipper and traefik using the relevant switches
