Verifying the Scaling Up

9.2.3 Verifying the Scaling Up

Verify the new OUDSM pod oudsm-2 has started:

kubectl get pod,service -o wide -n <namespace>

For example:

kubectl get pods,service -n oudsmns

The output will look similar to the following:

NAME          READY   STATUS    RESTARTS   AGE   IP            NODE            NOMINATED NODE   READINESS GATES
pod/oudsm-1   1/1     Running   0          88m   10.244.0.19   <worker-node>   <none>           <none>
pod/oudsm-2   1/1     Running   0          15m   10.245.3.45   <worker-node>   <none>           <none>

service/oudsm-2     ClusterIP   10.96.31.201    <none>        7001/TCP,7002/TCP   15m   app.kubernetes.io/instance=oudsm,app.kubernetes.io/name=oudsm,oudsm/instance=oudsm-2

Note:

It will take several minutes before all the services listed above show. While the oudsm-2 pod has a STATUS of 0/1 the pod is started but the OUDSM server associated with it is currently starting. While the pod is starting, you can check the startup status in the pod log, by running the following command:

kubectl logs oudsm-2 -n oudsmns
