In the MCP 2019.2.15 maintenance update, Mirantis introduces the following enhancements for OpenStack:

To obtain the enhancements, follow the steps described in Apply maintenance updates.

RabbitMQ queue mirroring

Implemented the capability to enable RabbitMQ mirroring policy for clustered RabbitMQ configurations to reduce failures during the RabbitMQ cluster recovery. For new deployments, mirroring is enabled by default.

Randomized RabbitMQ reconnection intervals

Implemented the capability to enable random reconnection intervals for RabbitMQ on the required OpenStack services. The feature enhances the RabbitMQ cluster operation in large OpenStack environments.

RabbitMQ queues troubleshooting

Added a detailed procedure on how to identify and fix non-functional queue bindings of a clustered RabbitMQ instance.

User ID support in the Nova policy

Implemented the capability to use the user_id attribute in the Nova API os_compute_api:os-remote-consoles policy. For example, to allow console access only to the instance creator or administrative user, set this policy to "os_compute_api:os-remote-consoles": "is_admin:True or (project_id:%(project_id)s and user_id:%(user_id)s)".
