Before you start

⚡ Remember to share your controller ssh public key id_rsa.pub with the worker node you want to control.

ℹ️ The list of worker nodes will store in inventories folder

Sharing Controller public key

1. Generate ssh key in Controller

   $ ssh key-keygen
   

2. Copy public key to worker node

   Controller

   $ cat ./.ssh/id_rsa.pub
   ssh-rsa XXXXXXXXXXXX...
   

   Worker Node

   $ vi ./.ssh/authorized_keys
   

Playbook
