I want to delete the cluster master node and rejoin the cluster. When trying to rejoin the node a problem occurs and rejoining fails. What can be done?

To delete the cluster master, we need to set the cluster master to a different master machine first.

1. On the admin machine: change the IP-Address from the current to new cluster master in:

1. /var/lima/<name_of_cluster>/clusterStorage.yaml
2. ~/.kube/config
1. Delete the node
2. Delete the images to prevent interference: ctr -n k8s.io i rm $(ctr -n k8s.io i ls -q)
3. Change IP on new cluster master in /etc/kubernetes/admin.conf
4. Change IPs in config maps:

1. kubectl edit cm kubeadm-config -n kube-system
2. kubectl edit cm kube-proxy -n kube-system
3. kubectl edit cm kubeadm-config -n kube-system
4. kubectl edit cm cluster-info -n kube-public
1. Restart kubelet
2. Rejoin the node
