Clean up lab 2.2
Hi, I messed up while running scripts (K8sMaster.sh & K8Second.sh). I want to perform cleanup and restart the whole thing from the beginning (on the same VMs). So I performed 'kubectl delete node ' on master VM and 'kubectl delete node ' on worker VM. When I re ran these scripts, I got bunch of errors. For ex: [ERROR DirAvailable--etc-kubernetes-manifests]: /etc/kubernetes/manifests is not empty [ERROR Port-6443]: Port 6443 is in use etc.....
Is there any cleanup script available?

Hi @pbbhaskar,
There is a
kubeadm reset
command that does some cleanup, but in the past it did not remove all the artifacts that were created by thekubeadm init
and thekubeadm join
commands on the master and worker nodes respectively. Thekubectl delete node
command only removes thenode
object from the cluster, otherwise does not cleanup thekubeadm
related artifacts.You can try a
reset
then anotherinit
andjoin
commands from the lab scripts, but it is not a guaranteed approach for a healthy cluster. I would recommend a fresh start with new VMs, and re-run the 2 shell scripts.Regards,
