According to Python 3 Porting guide http://docs.pythonsprints.com/python3_porting/py-porting.html Exceptions were changed in a few ways for Python 3. First, strings are no longer usable as exceptions. Additionally, the raise syntax no longer accepts comma-separated arguments, instead working with exception instances. Perhaps the largest difference in Python 3 is that exception objects are only available via the as keyword, which was introduced in 2.6.

Kolla Overview
The Kolla project is a member of the OpenStack Big Tent Governance. Kolla's mission statement is:
Kolla provides production-ready containers and deployment tools for
operating OpenStack clouds.Kolla provides Docker containers and Ansible playbooks to meet Kolla's mission. 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
Please get started by reading the Developer Quickstart followed by the Ansible Deployment Guide.
Docker Images
The Docker images are built by the Kolla project maintainers. A detailed process for contributing to the images can be found in the image building guide. Images reside in the Docker Hub Kollaglue repo.
The Kolla developers build images in the kollaglue namespace for the following services for every tagged release and implement Ansible deployment for them:
- Ceilometer
- Cinder
- Glance
- Haproxy
- Heat
- Horizon
- Keepalived
- Keystone
- Mariadb + galera
- Mongodb
- Neutron (linuxbridge or neutron)
- Nova
- Openvswitch
- Rabbitmq
$ sudo docker search kollaglueA list of the upstream built docker images will be shown.
Directories
- ansible - Contains Anible playbooks to deploy Kolla in Docker containers.
- compose - Contains the docker-compose files serving as a compose reference. Note compose support is removed from Kolla. These are for community members which want to use Kolla container content without Ansible.
- demos - Contains a few demos to use with Kolla.
- devenv - Contains an OpenStack-Heat based development environment.
- docs - Contains documentation.
- etc - Contains a reference etc directory structure which requires configuration of a small number of configuration variables to achieve a working All-in-One (AIO) deployment.
- docker - Contains jinja2 templates for the docker build system.
- tools - Contains tools for interacting with Kolla.
- specs - Contains the Kolla communities key arguments about architectural shifts in the code base.
- tests - Contains functional testing tools.
- vagrant - Contains a vagrant VirtualBox-based development environment.
