Configure Kubernetes Services on the Master

Perform the following steps to configure Kubernetes services on the master:

1. Edit /etc/kubernetes/apiserver to appear as such. The service_cluster_ip_range IP addresses must be an unused block of addresses, not used anywhere else. They do not need to be routed or assigned to anything.

   # The address on the local server to listen to.
   KUBE_API_ADDRESS="--address=0.0.0.0"
   
   # Comma separated list of nodes in the etcd cluster
   KUBE_ETCD_SERVERS="--etcd-servers=http://127.0.0.1:4001"
   
   # Address range to use for services
   KUBE_SERVICE_ADDRESSES="--service-cluster-ip-range=10.254.0.0/16"
   
   # Add your own
   KUBE_API_ARGS=""
   

2. Start the appropriate services on master:

   for SERVICES in etcd kube-apiserver kube-controller-manager kube-scheduler; do
   	systemctl restart $SERVICES
   	systemctl enable $SERVICES
   	systemctl status $SERVICES
   done
   

3. To add the other node, create the following node.json file on the Kubernetes master node:

   {
       "apiVersion": "v1",
       "kind": "Node",
       "metadata": {
           "name": "photon-node",
           "labels":{ "name": "photon-node-label"}
       },
       "spec": {
           "externalID": "photon-node"
       }
   }
   

4. Create a node object internally in your Kubernetes cluster by running the following command:

   $ kubectl create -f ./node.json
   
   $ kubectl get nodes
   NAME                LABELS              STATUS
   photon-node         name=photon-node-label     Unknown
   

Note: The above example only creates a representation for the node photon-node internally. It does not provision the actual photon-node. Also, it is assumed that photon-node (as specified in name) can be resolved and is reachable from the Kubernetes master node.
