The Oslo.messaging project implemented a nice feature called Queue Manager. This means that instead of using random queue names in RabbitMQ, it uses queue names composed of hostname, process-name and a counter. For proper functioning, the code stores some informations in /dev/shm. This is needed to avoid creating queues with the same name. We'd otherwise hit this where multiple services run under mod_wsgi, or with services such as Magnum just within a single container as it needs to create multiple "reply" queues. This patch mounts /dev/shm in containers where oslo_messaging is used. This is enabled when ``om_enable_queue_manager`` is set to ``True``. Queue Manager will be supported in a follow-up patch.

Kolla Ansible
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 Kolla Ansible.
Get started by reading the Developer Quickstart.
