I have a kubernetes cluster running on 2 machines (master-minion node and minion node). I want to add a new minion node without disrupting the current set up, is there a way to do it?
I have seen that when I try to add the new node, the services on the other nodes stops it, due to which I have to stop the services before deploying the new node to the existing cluster.
To do this in the latest version (tested on 1.10.0) you can issue following command on the masternode:
kubeadm token create --print-join-command
It will then print out a new join command (like the one you got after kubeadmn init):
kubeadm join 192.168.1.101:6443 --token tokentoken.lalalalaqyd3kavez --discovery-token-ca-cert-hash sha256:complexshaoverhere
You need to run kubelet and kube-proxy on a new minion indicating api address in params.
Example:
kubelet --api_servers=http://<API_SERVER_IP>:8080 --v=2 --enable_server --allow-privileged
kube-proxy --master=http://<API_SERVER_IP>:8080 --v=2
After this you should see new node in
kubectl get no
