One to read: "Using Ansible for system updates"
Thinking of using Ansible to perform your system updates for you? Well, why not take a look at this. I've been using a fabric script to do stuff like this for projects I'm involved in, but this looks a lot more sensible than what I was doing. Thanks Redpill Linpro!
As a result of this post, I've now updated that playbook (using more current modules) to a slightly cleaner version without load balancer updates! That playbook is on my Github Repository.
