Keep StatefulSet's Pods Down
Go back to listCheck what happens when all pods of a Kubernetes StatefulSet aren't coming up again.
Motivation
Typically, Kubernetes tries to keep as many pods running as desired for a Kubernetes StatefulSet. However, some circumstances may prevent Kubernetes from achieving this, like missing resources in the cluster, problems with the StatefulSet's probes, or a CrashLoopBackOff. You should validate what happens to your overall provided service when a given StatefulSet is directly affected by this or one of the upstream services used by your StatefulSet.
Structure
To keep the pods down for a given StatefulSet, we first kill all the pods in the StatefulSet. Simultaneously, we will scale down the Kubernetes StatefulSet to 0 to simulate that these pods can't be scheduled again.
At the of the experiment, we automatically roll back the StatefulSet's scale to the initial value.
