Ansible roles and playbooks for Raspberry pi cluster

Inspired by:

• https://github.com/chesterbr/chester-ansible-configs
• https://github.com/cloudalchemy/ansible-node-exporter

Use provisioning.yml playbook like this:

ansible-playbook -i hosts provisioning.yml -k
ansible-playbook -i hosts cluster.yml 

After playing everything from Ansible - log into your server node and run:

$ sudo k3s kubectl get node -o wide

You should see all of your nodes broadcasting a Ready status.
