Ansible roles/glance/task/main.yml playbook for Glance API Deployment

I am working on a project at work to deploy Keystone and Glance. I’ve currently been tasked with finishing off the glance role part of the playbook with the basic setup tasks and retrieving the basic qcow2 images for the various distributions and automatically retrieving and populating the glance API image-list. Here is how I did it;

This is using an encrypted group_vars all vars.yml which contains sensitive password variables like GLANCE_DBPASS

This file shows how Glance SQL database, permissions, population and images are uploaded to glance for use by openstack compute.

The above is in yaml format which is really tricky so what your syntax when using it. It is VERY sensitive.

After this runs we are left with a nice glance image-list output. Glance is ready for compute to use the qcow2 images we associated using the openstack Glance API.
