Kubernetes

You will need a kubernetes environment to deploy and use UnderStack. Good options for a small kubernetes development environment are k3s and kind.

Kubernetes Tools

UnderStack also uses common kubernetes tools: Helm, Kustomize, and Kubeseal.

Helm

Helm is a package manager for kubernetes and UnderStack uses a number of upstream Helm charts.
