Setup, configuration and documentation for my local Ubuntu workstation following an infrastructure as code approach.

Requirements Overview

  1. Setup my local workstation with minimal manual interactions.

  2. Add or update packages without any risk → avoid having to repair broken installations (dumping the broken setup and reverting to a working one is preferred).

  3. Test the setup regularly (automated) to ensure a new installation from scratch will work.

Quality Goals

  1. The whole setup of my local workstation, all my Vagrantboxes and all my Docker images is Infrastructure as Code.

  2. Software installations through the classic package managers like apt should be avoided. As much as possible should run inside docker containers. This is true for the host machine as well as Vagrantboxes.
