There are several ways to run small Kubernetes clusters: k3s and k3d, minikube, and microk8s to name a few. Currently, my favorite is the Kubernetes provided by Docker Desktop for Mac. But this doesn’t help my friends (or myself) when I am on a Linux laptop. It would be nice to have one lightweight and shared environment for Kubernetes. Luckily, one of the Kubernetes groups has released KinD - Kubernetes in Docker.

At work we have been expanding the testing coverage of our auth service and have discovered the perfect storm of edge cases around test caching and Go’s test building. In short, we had tests that looked like they were passing locally but would fail sporadically in CI because Go will run the tests inside of a package sequentially but build and test each package in parallel (up to the number of CPU cores).
