Hexadeca Pi cluster running Kubernetes

Kubernetes cluster using 16 Raspberry Pi 3B+ plus one as master. Trying to make it as seamless as possible while learning Ansible for automation.

End goal is to drive wife nuts with idiot project.

/ ! \ WORK IN PROGRESS, UNUSABLE STATE

Specs

• 64 cores (22.4Ghz combined)
• 1TB of total storage (each node is equipped with a 64GB uSD)

Pre-requis

• Money to throw out your window
• Time to waste
• Ansible installed (on Mac it's brew install ansible)
  • If you have an error with permission blablabla, run:
    • sudo mkdir /usr/local/Frameworks
    • sudo chown $(whoami):admin /usr/local/Frameworks
    • Rerun brew
• All node have the latest Rapbian installed
• They have a static IP
• You have injected your own ssh keys

Basic usage:

• Clone the repo.
• By default, the repo/playbook assume that:
  • Nodes have a fixed ip as 192.168.0.XXX
    • Master: 192.168.0.150
    • Workers: 192.168.0.151 to 166
• Edit the hosts files at ansible/hosts if that's not the case
• You private SSH keys is already in each node
• Go to hexadeca/ansible
• Run ansible-playbook -i hosts 1-cluster-preparation.yml

It will update/upgrade Raspbian, install a bunch of basic stuff, put Docker and Kubeadm.
