Kubernetes: 3TB Less Storage, 80GB Less RAM, and More Features

After getting the Talos cluster running and ArgoCD wired up, the next thing to do was actually move workloads into it. That process ended up being a general cleanup as well - going through what was running, deciding what was still needed, and getting rid of the rest. The result was 3TB less storage consumed and 80GB less RAM allocated across the hosts, while actually running more services than before.

I have been running Kubernetes for a while, but still had a lot of the "one VM per service" mindset from before. Also wasn't really confident enough in Kubernetes to just move my workloads into it and delete the old VMs.

I also started moving VMs to Containers due to all the security vulnerabilites that have been popping up around Linux and other stuff lately. So it is either patching VMs more often or moving more into containers.
