StatefulSet Basics - setting update strategy to OnDelete

[brianjester]

When attempting to run this command:

kubectl patch statefulset web -p '{"spec":{"updateStrategy":{"type":"OnDelete"}}}'

I receive this message:

The StatefulSet "web" is invalid: spec.updateStrategy.rollingUpdate: Invalid value: apps.RollingUpdateStatefulSetStrategy{Partition:0, MaxUnavailable:(*intstr.IntOrString)(nil)}: only allowed for updateStrategy 'RollingUpdate'
