I completed the above steps and then I tried to access the local CLI using these steps:

The document has this step:

For a lab setup where I dont expect any queries from outside the localhost, Is this step required?

I skipped the above step and configured the clouds.yaml. I hit few issues:

1)  I cannot access the GUI using the <floating address>:31000 port from the browser?

2) The local CLI commands such as "openstack image list" keep failing with 

controller-0:~$ openstack image list
Failed to discover available identity versions when contacting http://keystone.openstack.svc.cluster.local/v3. Attempting to parse version from URL.
Service Unavailable (HTTP 503)
controller-0:~$ source /etc/platform/openrc
[sysadmin@controller-0 ~(keystone_admin)]$ export OS_CLOUD=openstack_helm
[sysadmin@controller-0 ~(keystone_admin)]$ openstack image list
The request you have made requires authentication. (HTTP 401) (Request-ID: req-ed0117db-5fc2-4d21-9175-d8fcd6434fb7)

I am not sure what exactly I am missing wrt the configuration.

Can someone please help me by providing any pointers ?

Thanks
