 | *`serviceName`* __string__ | serviceName is the name of the service that governs this StatefulSet. This service must exist before the StatefulSet, and is responsible for the network identity of the set. Pods get DNS/hostnames that follow the pattern: pod-specific-string.serviceName.default.svc.cluster.local where "pod-specific-string" is managed by the StatefulSet controller.
 | *`podManagementPolicy`* __link:https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.23/#podmanagementpolicytype-v1-apps[$$PodManagementPolicyType$$]__ | podManagementPolicy controls how pods are created during initial scale up, when replacing pods on nodes, or when scaling down. The default policy is `OrderedReady`, where pods are created in increasing order (pod-0, then pod-1, etc) and the controller will wait until each pod is ready before continuing. When scaling down, the pods are removed in the opposite order. The alternative policy is `Parallel` which will create pods in parallel to match the desired scale without waiting, and on scale down will delete all pods at once.
 | *`updateStrategy`* __link:https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.23/#statefulsetupdatestrategy-v1-apps[$$StatefulSetUpdateStrategy$$]__ | updateStrategy indicates the StatefulSetUpdateStrategy that will be employed to update Pods in the StatefulSet when a revision is made to Template.
+| *`minReadySeconds`* __integer__ | The minimum number of seconds for which a newly created StatefulSet pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready).
