If you have 10 Pods and the Pod takes 2 seconds to be ready and 20 to shut down this is what happens: The first Pod is created, and a previous Pod is terminated. The new Pod takes 2 seconds to be ready after that Kubernetes creates a new one. In the meantime, the Pod being terminated stays terminating for 20 seconds.

The Vertical Pod Autoscaler vpa-recommender deployment analyzes the hamster Pods to see if the CPU and memory requirements are appropriate. If adjustments are needed, the vpa-updater relaunches the Pods with updated values. Wait for the vpa-updater to launch a new hamster Pod. This should take a minute or two.
Anything else we need to know?: I realize that in my example, the HPA is unable to read the resource metric and that may be a contributing factor in the calculation of the desired replica count. However, when minReplicas is set higher than 1, then the desired replica count is calculated to be vale of minReplicas.For example, deploying the same …
