Ussuri Series Release Notes¶

18.0.0.0b1-116¶

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

The trove service setup in keystone will now be executed through delegation to the trove_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.
```
trove_service_setup_host: "{{ groups['utility_all'][0] }}"
```

The rabbitmq server parameters have been replaced by corresponding oslo.messaging RPC and Notify parameters in order to abstract the messaging service from the actual backend server deployment. - trove_oslomsg_rpc_servers replaces trove_rabbitmq_servers - trove_oslomsg_rpc_port replaces trove_rabbitmq_port - trove_oslomsg_rpc_use_ssl replaces trove_rabbitmq_use_ssl - trove_oslomsg_rpc_userid replaces trove_rabbitmq_userid - trove_oslomsg_rpc_vhost replaces trove_rabbitmq_vhost - added trove_oslomsg_notify_servers - added trove_oslomsg_notify_port - added trove_oslomsg_notify_use_ssl - added trove_oslomsg_notify_userid - added trove_oslomsg_notify_vhost - added trove_oslomsg_notify_password

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

The default TLS version has been set to TLS1.2. This only allows version 1.2 of the protocol to be used when terminating or creating TLS connections. You can change the value with the trove_ssl_protocol variable.
