In the first part of this post — available here — we have covered the basic configuration and logic required in order to write an idempotent Ansible module. In this post, we will see how to run a series of tests good enough to make sure your module works as…

You certainly remember the first time you ran an Ansible playbook: a few lines of code grouped together in a bunch of tasks that did a lot of magic. Struck by curiosity, you surely asked yourself what could be concealed behind that thing called module. How was it possible that…

Because you are reading this post, you’re likely aware of the great power of the Jinja2 templating language.

Yes, that happens when you write (probably by coincidence…) a good piece of python crap that just works, it does its job without complaining about errors and exceptions. I deployed it 2 years ago and almost forgotten about its existence in our infrastructure..until now. …

Long intro that you cannot skip. In January 2020 I had the pleasure to attend Cisco Live in Barcelona. It was my first time and I was so excited that basically I signed up for all possible sessions for DevNet zone. To be honest, I was not sure what I…
