Error saying Ports in use when initializing the cluster

Question

I'm trying to set up a cluster on my virtual machine with one master and two nodes. I initialize the cluster using the following command:

kubeadm init --apiserver-advertise-address=<ip-address-of-kmaster-vm> --pod-network-cidr=192.168.0.0/16

But I get errors:

Why am I getting so many errors and how do I get rid of them?

Answer 1

You get this error because there already might be another cluster built on that system. execute the following command on master as well as all the nodes.

kubeadm reset

and execute the same kubeadm init command again.

It should work.
