Add nodes to the cluster
If you have two Bitnami Kubernetes Sandbox Stack instances (each with their own Kubernetes cluster), you can create a cluster with them. In order to do so, one of the instances will be the master and the other will be the worker (you can freely chose which one is the master). This worker node will join the master node’s cluster.
Get the master node token
Execute the following command on the master node:
$ kubeadm token list
Write down the token listed. It will be denoted as CLUSTER_TOKEN. Get the master node’s private IP address:
Write down the IP address. It will be denoted as MASTER_IP.
Join the worker node to the master
Execute the following commands to tear down the worker’s cluster.
$ kubeadm reset $ sudo rm /etc/kubernetes -r
Execute this command to join the master node’s cluster. Replace the CLUSTER_TOKEN and MASTER_IP placeholders:
$ kubeadm join --token=CLUSTER_TOKEN MASTER_IP:6443
After this command, the following command (in the master node) will show two nodes.
$ kubectl get nodes NAME STATUS AGE VERSION node1 Ready 1d v1.7.5 node2 Ready 1d v1.7.5
