Ansible playbooks to manage Orange Pi Zero 2 clusters

This repository contains a set of Ansible playbooks that help to set up and manage an Orange Pi Zero 2 cluster.

How to run?

Install Ansible on a control node and define an inventory (/etc/ansible/hosts). For example:

[opiesz]
192.168.1.101		ansible_user=orangepi		hostname=ozpi01
192.168.1.102		ansible_user=orangepi		hostname=ozpi02
192.168.1.103		ansible_user=orangepi		hostname=ozpi03
192.168.1.104		ansible_user=orangepi		hostname=ozpi04

Run a playbook as follows:

ansible-playbook some-playbook.yml --ask-pass

Or:

ansible-playbook some-playbook.yml --ask-pass --ask-become-pass
