A bit of Ansible for some fun homelab automation!

Prereqs

Before you can run Ansible against a 'host' ("Target Machine(s)") you must add your local ssh key to the 'host(s)' (so it knows who you are)

1. Optional - if you haven't already generated your local (Ansible Controller) SSH Key Pair...

   • ssh-keygen

2. Copy your (Ansible Controller) PUBLIC ssh key (the file (ls ~/.ssh one ending in .pub) to the remote Host(s) you want to Target with Ansible

   • ssh-copy-id <name>@<host>
   • e.g.
   • ssh-copy-id tdawson@hpi516
   • ssh-copy-id tdawson@hpi732

NOTE : If the User is different (e.g tonydawson on one side and tdawson on the other) - you will need to set this explicitly in the hosts file

[all:vars]
ansible_user=<name>

Test Connection with Ansible Ping/Pong

With the remote public keys in place, try an Ansible Ping

• ansible -i hosts.ini all -m ping

You should get a 'Pong' in return...
