Configure custom cluster domain

Override the default Kubernetes cluster domain used by the Splunk Operator.

By default, the Splunk Operator uses a Kubernetes cluster domain of cluster.local to calculate fully qualified domain names (FQDN) for each instance. If you configured a custom domain for your Kubernetes cluster, add a CLUSTER_DOMAIN environment variable to the operator deployment spec to override the default.

Add a CLUSTER_DOMAIN environment variable to the operator's deployment spec with your custom domain value:
CODE 
- name: CLUSTER_DOMAIN
  value: "mydomain.com"
