The number of pods is still 3 because it takes a while for the number of pods to increase and the cluster

when load is increased
List the deployment after a few more seconds, and the number of pods has increased to 5 as shown in
Figure 13-19. The autoscaler has scaled up the cluster by increasing the number of pods.
