Cluster Management with Ansible

Now that I have my “base cluster” up and running with ProxMox, it’s time to turn my attention to how I’m going to manage it.

After creating a new management user I setup ssh certs to permit ssh traffic from the master to slave systems.

Instalation of Ansible was a breeze

$ sudo apt update
$ sudo apt install software-properties-common
$ sudo apt-add-repository --yes --update ppa:ansible/ansible
$ sudo apt install ansible

After creating an inventory file, and then a quick and dirty playboook...I tested it out and...

voila!

First run went smashing..although it showed that there WAS actually an update or two on 2/3 of the servers.

After running my playbook again it looks like everything was in fact in order.
