How to Run a Python CLI Tool Inside a Docker Container
Have you ever faced a problem sharing your python scripts with the rest of your team? You need to ensure a lot of things for your script to run on a recipient's machine.

It's been a while since my last post and I want to shed some light on what I've been up to and what are my plans for the future of this site.

Automate Windows VM Creation and Configuration in vSphere Using Packer, Terraform and Ansible (Part 1 of 3)
In this series of posts I'd like to show how to automate the process of setting up virtual infrastructure consisting of several Windows Server 2016 machines. Most articles I've come across cover the use of cloud providers (e.g. AWS) as a virtualization platform, so I decided to make a write up about my experience with VMware vSphere.
