# Kubernetes Clusters

> WIP, not finished yet.

I'm running two Kubernetes clusters, one for production and one for testing.

I prefer to use [k3s] as the Kubernetes distribution, because it's lightweight, easy to install, and
full featured(see [what-have-k3s-removed-from-upstream-kubernetes] for details).

## Hosts

## Kubernetes Resources

Kubernetes resources are deployed and managed separately through
[nix-config/pulumi/k8s/](../../pulumi/k8s/).
