Progressive Load Lab

Make sure you gave enough time for Busyboxes to generate the load.

Verify the status of the deployment and the Horizontal Pod Autoscaler by running the following command:

kubectl get deployment php-apache -n autoscale-test


➜   kubectl get deployment php-apache -n autoscale-test
NAME         READY   UP-TO-DATE   AVAILABLE   AGE
php-apache   45/84   84           45          33m

➜   kubectl get hpa -n autoscale-test                                      
NAME         REFERENCE               TARGETS    MINPODS   MAXPODS   REPLICAS   AGE
php-apache   Deployment/php-apache   108%/40%   1         100       84         28m

Review the changes that happened to the cluster in spot UI. You can see that most of the VM’s were deployed by our Example-1 VNG and as busy box is generating cpu load all our VM’s are highly utilized. Load

At this point you succesfully simulated a production cluster where your application is scaling according to the load. The load is beeing generated by Busybox to simulate users and Ocean is handling all the underlying infrastructure Scaling.

Do not forget to visit the “Cleanup” section to stop the Busyboxes from generating additional load after you finished with this lab.
