I need to modify VM's hostname. VMs are configured by kubernetes.(Master2,worker 3)
Should I reconfigure the kubeadm ? Could you know how to change the VM's hostname ?
VM's OS is CentOS 7.4.
Can i ask you, why you want to modify name? in kubernets , labels serve as identifying attribute. You can add new labels to nodes with below command:
kubectl label <NODE_NAME> short_name=worker1So every use case can be satisfied with label.
