14.Hold Back the Update

StatefulSet cache runs three redis:7.2 Pods in depths-1638vk7 with partition: 3:

kubectl get sts,pods -n depths-1638vk7
kubectl get sts cache -n depths-1638vk7 -o jsonpath='{.spec.updateStrategy}'

Set the image to redis:7.4 and count how many Pods change. Lower the partition to 2 and look again. Then lower it to 0 and watch the order in which the remaining Pods are replaced.

Something unclear, wrong or missing?
