ansible-role-k3s

This document describes a number of ways of consuming this Ansible role for use in your own k3s deployments. It will not be able to cover every use case scenario but will provide some common example configurations.

Requirements

Before you start you will need an Ansible controller. This can either be your workstation, or a dedicated system that you have access to. The instructions in this documentation assume you are using ansible CLI, there are no instructions available for Ansible Tower at this time.

Follow the below guide to get Ansible installed.
