K8s - add kubeadm to existing cluster
If Kubeadm was used to generate the original cluster then you can log into the Master and run kubeadm token generate
. This will generate an API Token for you. With this API token your worker nodes will be able to preform an authenticated CSR against your Master to perform a joining request. You can follow this guide from there to add a new node with the command kubeadm join
.
