raspberry-pi-dramble

I use Kind (and Minikube, and a number of other solutions too), but this is kind of my "Kubernetes-the-really-hard-way" fun project. Note that I maintain a parallel configuration that runs a multi-node cluster on Vagrant for local development [1] as well as a docker environment built for CI purposes[2] using almost all the same images, with the same Ansible playbooks to configure them all across platforms.

What do you know, that's exactly how I do local development work for the cluster ;) https://github.com/geerlingguy/raspberry-pi-dramble/tree/mas...

I finally acquired enough Pi 4's (the 2GB RAM version—I can't find the 4GB version anywhere yet) to rebuild my Kubernetes cluster (www.pidramble.com) using the latest Pi. So far my takeaways are: 1. The official PoE HAT seems to work fine... but you can't shut down the Pi and keep it shut down—it seems to reboot if powered by the PoE HAT :/ 2. The Pi 4 feels slightly faster, but having double the RAM (I can't find 4 GB Pi 4's in stock anywhere) is reallllly nice for Kubernetes. 3. Docker is annoying to get running on Raspbian 10/Buster, since the standard repo has a broken version, and Docker's repo only has listings for Raspbian 9/Stretch. Therefore you have to hack around the install script a tiny bit to get Docker installed. I currently have Kubernetes running fine, but am having issues with the cluster networking (this seems to happen
