Revisiting k8s and upgrading

So, UGH.

I've been piddling with Kubernetes for a while, but the main tinkering piece I'm using has gotten long in the tooth. It's 1.21, and a quick check of the support lifecycle says supported ended 10 months ago. Even 1.24 will lose active support in about a week, and maint support will end in a couple months. The newest version is 1.27, and 6 versions seems like a lot to bounce through.

When I grabbed the repo I'm running this from, the rev it was at was 1.18, and I was able (with minimal pain) bring it up to 1.21. Now, if I remember correctly, I needed a Terraform plugin to move it past this rev, and I think it is time to look into that. I'd like to get the code to something currently supported.

Besides that, I want to understand how things are running a bit better. There are a few support pieces, and I'm not strongly leaning any way, but I'd like to know what things are.

Finally, I think I'd like to hack a bit, and this means actually doing some testing and also being able to mitigate things I find.
