Configure the Kubernetes services on Node

Perform the following steps to configure the kubelet on the node:

  1. Edit /etc/kubernetes/kubelet to appear like this:

     ###
     # Kubernetes kubelet (node) config
    
     # The address for the info server to serve on (set to 0.0.0.0 or "" for all interfaces)
     KUBELET_ADDRESS="--address=0.0.0.0"
    
     # You may leave this blank to use the actual hostname
     KUBELET_HOSTNAME="--hostname_override=photon-node"
    
     # location of the api-server
     KUBELET_API_SERVER="--api_servers=http://photon-master:8080"
    
     # Add your own
     #KUBELET_ARGS=""
    
  2. Start the appropriate services on the node (photon-node):

     for SERVICES in kube-proxy kubelet docker; do 
         systemctl restart $SERVICES
         systemctl enable $SERVICES
         systemctl status $SERVICES 
     done
    
  3. Check to make sure that the cluster can now see the photon-node on photon-master and that its status changes to Ready.

    kubectl get nodes
    NAME                LABELS              STATUS
    photon-node          name=photon-node-label     Ready
    

    If the node status is NotReady, verify that the firewall rules are permissive for Kubernetes.

    • Deletion of nodes: To delete photon-node from your Kubernetes cluster, one should run the following on photon-master (please do not do it, it is just for information):
    kubectl delete -f ./node.json
    

Result

You should have a functional cluster. You can now launch a test pod. For an introduction to working with Kubernetes, see Kubernetes documentation.
