Use K3s Cluster Playbook

Deployment environment must have Ansible 2.4.0+ Master and nodes must have passwordless SSH access

create inventory/pi-cluster.ini containing master and node hosts. For example:

[master]
192.168.0.10

[node]
192.168.0.[11:12]

[k3s_cluster:children]
master
node

edit k3s-cluster/group_vars/all.yml to change cluster variables
run playbook

ansible-playbook k3s-cluster/site.yml -i inventory/pi-cluster.ini

copy cluster config to get access

scp ansible@master_ip:~/.kube/config ~/.kube/config
