I’ve started to dig into Linux sysadmin topics. The whole area of actually setting up a machine, configuring a proper network, and keeping everything up-to-date and secure while automating most (if not all of this) has been a big blindspot of mine in these past years.
To not blindly learn random things I made it my goal to use a bunch of Raspberry Pis (or ODROIDS) and cluster them using Kubernetes or Nomad, and to do this from scratch (install OS, network etc). I assume that this will touch on all the relevant topics. It’s also a great basis for the homelab I’ve always wanted to build to run a media center and more.
