Kubernetes-in-Kubernetes

Deploy Kubernetes in Kubernetes using Helm

Requirements

Kubernetes v1.21+
Helm v3
cert-manager v1.0.0+

Quick Start

Preparation

Install cert-manager.
If you running over minikube you might also need to install a provisioner, you can use local-path-provisioner for example.

Installation

helm repo add kvaps https://kvaps.github.io/charts
helm install foo kvaps/kubernetes --version 0.13.4 \
  --namespace foo \
  --create-namespace \
  --set persistence.storageClassName=local-path

Cleanup

kubectl delete namespace foo

Usage

Kubernetes-in-Kubernetes is just a control plane, in most cases it's useless without workers.
If you're looking for a real use case, check out the following projects that implement worker nodes management:
