Ussuri Series Release Notes¶

18.0.0.0b1-147¶

The role now supports using the distribution packages for the OpenStack services instead of the pip ones. This feature is disabled by default and can be enabled by simply setting the swift_install_method variable to distro.

Support separate oslo.messaging services for RPC and Notifications to enable operation of separate and different messaging backend servers in swift.

The service setup in keystone for swift will now be executed through delegation to the swift_service_setup_host which, by default, is localhost (the deploy host). Deployers can opt to rather change this to the utility container by implementing the following override in user_variables.yml.
```
swift_service_setup_host: "{{ groups['utility_all'][0] }}"
```

The rabbitmq server parameters have been replaced by corresponding oslo.messaging Notify parameters in order to abstract the messaging service from the actual backend server deployment. - swift_oslomsg_notify_servers replaces swift_rabbitmq_telemetry_servers - swift_oslomsg_notify_port replaces swift_rabbitmq_telemetry_port - swift_oslomsg_notify_use_ssl replaces swift_rabbitmq_telemetry_use_ssl - swift_oslomsg_notify_userid replaces swift_rabbitmq_telemetry_userid - swift_oslomsg_notify_vhost replaces swift_rabbitmq_telemetry_vhost - swift_oslomsg_notify_password replaces swift_rabbitmq_telemetry_password

The variable swift_requires_pip_packages is no longer required and has therefore been removed.
