Deploy Kubernetes in Kubernetes using Helm

• Kubernetes v1.15+
• Helm v3
• cert-manager v0.14+

• Install cert-manager.

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

• Clone repo locally and cd to helm charts directory:

  git clone https://github.com/kvaps/kubernetes-in-kubernetes
  cd kubernetes-in-kubernetes/deploy/helm

kubectl create ns kubernetes
helm upgrade --install -n kubernetes foo kubernetes --wait

helm -n kubernetes delete foo
kubectl delete ns kubernetes

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:

• Kubefarm - Automated Kubernetes deployment and the PXE-bootable servers farm
