I tried to figure out solution for the task.

Join the node node02 to the cluster I need to use the kubeadm configuration file located in /etc/kubeadm.conf for initialising cluster. Docker run on each nodes and apt is already configured.

I join the node node02 this way:

How to configure kubeadm from file /etc/kubeadm.conf and set master02 as the master ?

Both kubeadm join and kubeadm init takes a parameter --config which can point to the path of kubeadm config file.
If you do kubeadm init or kubeadm join --control-plane on a node it automatically becomes master node.
