At the moment, the process to determine if an image has changed or not relies on the Docker API which depending on the Docker release server can return different results. This patch addresses this issue by grabbing the SHA256 of the image before pulling (defaulting to None if it does not exist) and then comparing it after the pull is complete which should always be successful at determining if the image did change or not. The test for unknown status images is removed because this is not a possible scenario as we do not rely on status anymore except for failures (which are still tested).

Kolla-Ansible Overview
The Kolla-Ansible is a deliverable project separated from Kolla project.
Kolla-Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla-Ansible by reading the documentation online docs.openstack.org.
