I found the freezer guide is really not having the steps in place. This is the link to the installation guide. https://docs.openstack.org/freezer/latest/install/install-rdo.html#install-and-configure-components (https://docs.openstack.org/freezer/la...)

The step, Copy the configuration files to /etc/freezer/:

sudo cp etc/freezer/freezer-api.conf.sample /etc/freezer/freezer-api.conf

sudo cp etc/freezer/freezer-paste.ini /etc/freezer/freezer-paste.iniezer-paste.ini

The source files doesn't exist anywhere following the Installation instructions. Someone who has done Freezer kindly help me out with the procedure.
