A year of Kubernetes

About a year ago I thought it would be a good idea to learn a bit more about Kubernetes. We use Kubernetes as part of our server orchestration at work, and while most of it is abstracted a way, it rarely hurts to know how the various foundational layers are actually like.

At the time, I tried to set up a three-node cluster (two computers at home, one in the cloud), connected together by Tailscale (i.e. via Wireguard). This… kind of worked, but it was super chatty, and when we moved to Seattle we no longer had an unmetered internet connection.

Or, why doesn’t docker stop work for my Docker image?

I’ve had a Docker image which is intended to be approximately the most basic HTTP-compatible responder for a while. But, I built this originally for playing with Kubernetes, which doesn’t really give you direct access to anything.

When actually using it with Docker, I discovered that it wouldn’t actually shut down correctly with Ctrl-C or docker stop, and Docker would eventually have to docker kill it.
