at least 1 Node, better 3 with more ram and cpu

getting started

create your inventory from the example-inventory or edit the values directly

generate yourself a new cluster join token and insert it in the inventory with

kubeadm token generate

or use one for tests only e.g sw4xjw.xfar3wciairc2n7o

Then run the playbook:

ansible-playbook -i inventories/<example-inventory>/ install-all.yml

you can give your newly added Nodes the "worker" label with kubectl label node <nodeName> node-role.kubernetes.io/worker=worker
