I've got 3 VMs which can connect.
I've started up 1 master and 2 nodes.
However, I'm not sure what IP address to use here:
sudo kubeadm join <ip address>:6443 --token <token> --discovery-token-ca-cert-hash <ca-cert-hash>The actual IP I used to deploy the master (i.e. with kubeadm) was 192.168.56.101. And I can telnet from the node to the master using:
telnet 192.168.56.101 6443
E.g.
telnet 192.168.56.101 6443
Trying 192.168.56.101...
Connected to 192.168.56.101.
Escape character is '^]'.However trying kubeadm join on the node with that IP does not work. It just hangs.
Any suggestions?
run 'hostname -i' and grab the IP address. Use it in init command. The master IP address should be reachable from all the nodes
run
Kubernetes master is running at https://xxx.xxx.xx.xx:6443
KubeDNS is running at https://xxx.xxx.xx.xx:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
Kubernetes master IP it's what you are looking for
Did you deployed your CNI network ? Flannel or Calico for example ?
run this command to see if all your master pods are running.
kubectl get pods --all-namespaces
In your Node did you install docker and kubelet ?
