## Introduction ## Introduction
> The objective of this playbook is to automate the installation and setup of a kubernetes instance. The playbook consist of 3 main plays. For both controller and nodes, for controller only and for nodes only. It will ask user confirmation before moving on to each stage. By the end of the playbook two files will be created on the controller node named **worker_conn_string** and locally inside the playbook directory with the name **Remote_Files/worker_conn_string**. This will have the **connection string**. (Note:- If you want to join controllers or nodes manually later. For controllers use **--control-plane** flag) > The objective of this playbook is to automate the installation and setup of a kubernetes instance. The playbook consist of 3 main plays.
