Pibernetes - via microk8s and via Rancher

MicroK8s Flavour

on new pi

1. Image a microsdcard with ubuntu 64 bit pi image; boot & wait for cloud-init
2. hostnamectl set-hostname 'pi-slice-n'`
3. adduser
4. usermod -aG sudo
5. sudo snap install microk8s --classic
6. snap info microk8s

on primary node`

1. sudo microk8s.add-node

on new node

1. sudo microk8s.join :/

Done

Rancher Flavour

On Rancher Box

1. sudo docker run --privileged -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher
2. Once docker running, nav to ‘add cluster - custom’
3. Once at ‘Customize Node Run Command’; generate start commands:
   • at least one of each of etcd, control plane, worker
   • one node can be all three

EG:

1. One node as [etcd,control plane]
2. One node as [worker]

On Each pi node

1. sudo snap install docker.io
2. Copy ‘registration command’ from Rancher + run on each box

Back to Rancher Box

1. Observe nodes being added to cluster!
