= Customizing Pod Disruption Budgets

{ProductName} creates a pod disruption budget for every new `StatefulSet` or `Deployment`.
By default, these pod disruption budgets only allow a single pod to be unavailable at a given time by setting the `maxUnavailable` value in the`PodDisruptionBudget.spec` resource to 1.
You can change the amount of unavailable pods allowed by changing the default value of `maxUnavailable` in the pod disruption budget template.
This template applies to each type of cluster (Kafka and Zookeeper; Kafka Connect and Kafka Connect with S2I support; and Kafka Mirror Maker).

The following example shows customized `podDisruptionBudget` fields on a `template` property:

template:
    podDisruptionBudget:
        metadata:
            labels:
                key1: label1
                key2: label2
            annotations:
                key1: label1
                key2: label2
        maxUnavailable: 1
