openshift_master_cluster_hostname=master3.example.com


[masters]

master3.example.com

[lb]
master.example.com

2. Don't set openshift_logging_master_public_url in inventroy file and deploy logging via ansible playbook
   openshift_logging_install_logging=true
   #openshift_logging_master_public_url=https://master.example.com:8443

3. Check the deployconfig k
oc get dc logging-kibana -o yaml |egrep -A 1 'OAP_PUBLIC_MASTER_URL|OAP_LOGOUT_REDIRECT'

Actual results:
# OAP_PUBLIC_MASTER_URL and OAP_LOGOUT_REDIRECT was set to https://master1.example.com:8443
 oc get dc logging-kibana -o yaml |egrep -A 1 'OAP_PUBLIC_MASTER_URL|OAP_LOGOUT_REDIRECT'
        - name: OAP_PUBLIC_MASTER_URL
          value: https://master1.example.com:8443
        - name: OAP_LOGOUT_REDIRECT
          value: https://master1.example.com:8443/console/logout
