After the python tripleo client has been installed, Copy the sample undercloud.conf 

sudo cp /usr/share/instack-undercloud/undercloud.conf.sample ~/undercloud.conf

Edit the undercloud.conf 

here is how the undercloud.conf looks like after the editing has been done.

(undercloud) [stack@pike ~]$

There are other things that also you can set in the undercloud,conf, but for a simple and straight forward deployement for my scenario, this works well.

Perform the undercloud install 

Install the undercloud as per the parameters that have been specified in the undercloud.conf file.

Please note that undercloud install cannot be run as the root user, we have the stack user to perform this.

openstack undercloud install
