I noticed that node private-ip is same on all nodes, this could be due to vagrant Linux VM has default eth0 with 10.0.2.15 on all VM.
How to change after kubeadm initialization of kuberentes cluster?
I think just do whatever you need to change the IP and, if that is not all, restart the kubelet?
What have you tried? What errors did you get?
I am not sure how to change the node IP on existing node. My VM already have private IP, but node IP is showing something different, wanted to correct it.
Which command show them differently? Can you please share it and they outputs?
