== KUBERNETES_CLUSTER_DOMAIN

*Default value*: cluster.local

*Required*: false

*Multiple values*: false

This instructs the operator, which value it should use for the Kubernetes `clusterDomain` setting.
Make sure to keep this in sync with whatever setting your cluster uses.
Please see the documentation xref:guides:kubernetes-cluster-domain.adoc[on configuring the Kubernetes cluster domain] for more information on this feature.
