Working on creating a demo visualisation of my Kubernetes cluster that runs in the browser. Just got network visualisation working. Each image is its own actual bit of running code using a fetch-like API to talk to other pods, and the network emits events when this happens.

It doesn’t look like much but there’s 76,000 lines of Kubernetes code under there. I have a Kubelet, an apiserver, a probing subsystem, pod life cycle event generator, container GC, container runtime, container network, CoreDNS, various resource controllers. It is as realistic as I can make it.

As far as I can tell it’s about 270kb gzipped. So a lil chonky but ultimately well within what I’d consider acceptable for what it’s going to allow me to do.
