+#### Multi-AZ

+Spread replicas evenly across availability zones with a maximum skew of one:
+
+```yaml
+multiAz:
+  enabled: true
+  whenUnsatisfiable: ScheduleAnyway
+```
+
+This uses the `topology.kubernetes.io/zone` node label. Set
+`whenUnsatisfiable` to `DoNotSchedule` to make the constraint strict. Additional
+constraints can be set with `topologySpreadConstraints`.
