Configure Kubernetes Services on the Master
Perform the following steps to configure Kubernetes services on the master:
Edit
/etc/kubernetes/apiserver
to appear as such. Theservice_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=""
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
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" } }
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.
