Hello Everyone,
I am using keycloak operator, here I am not able to find how I can pass custom service name (hostname).
When I apply keycloak manifest its creating the service as below shown
here is my keycloak manifest

apiVersion: keycloak.org/v1alpha1
kind: Keycloak
metadata:
 labels:
     app: example-keycloak
 name: example-keycloak
 namespace: demo
spec:
 externalDatabase:
   enabled: true
 instances: 1
 externalAccess:
   enabled: True
 keycloakDeploymentSpec:
   experimental:
     env:
       - name: DB_DATABASE
         valueFrom:
           secretKeyRef:
             name: keycloak-pguser-keycloakuser
             key: dbname
       - name: DB_ADDR
         valueFrom:
           secretKeyRef:
             name: keycloak-pguser-keycloakuser
             key: host
       - name: DB_PORT
         valueFrom:
           secretKeyRef:
             name: keycloak-pguser-keycloakuser
             key: port
       - name: DB_PASSWORD
         valueFrom:
           secretKeyRef:
             name: keycloak-pguser-keycloakuser
             key: password
       - name: DB_USER
         valueFrom:
           secretKeyRef:
             name: keycloak-pguser-keycloakuser
             key: user

here is the service which is creating by keycloak
