When the cluster is deployed, how do you add resources (compute nodes)?
kube-dns is stuck waiting for resources with "no nodes available to schedule pods"

Hi, thanks for interest!
Currently I'm working on new kubefarm project which uses kubernetes-in-kubernetes and enables node provisioning for it over PXE.
@egeneralov also was thinking to prepare ansible backend for it.

Unfortunately, both implementations are not finished yet, but already now, you can expose kubernetes-in-kubernetes using standard Kubernetes service with nodePort or loadBalancer and join nodes using standard kubeadm binary.

By the way do not forget to fill up the certSANs information, otherwise kubelet and kubectls will refuse the SSL connection

Thanks for the reply, I will follow the project on your repo and see the evolution.
We can close the issue for the moment and will open a new one later if needed.
