Train Series Release Notes

18.0.0.0b1-94

New Features

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

• The service setup in keystone for sahara will now be executed through delegation to the sahara_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.

  sahara_service_setup_host: "{{ groups['utility_all'][0] }}"
  

Deprecation Notes

• The rabbitmq server parameters have been replaced by corresponding oslo.messaging RPC and Notify parameters in order to abstract the messaging service from the actual backend server deployment. - sahara_oslomsg_rpc_servers replaces sahara_rabbitmq_servers - sahara_oslomsg_rpc_port replaces sahara_rabbitmq_port - sahara_oslomsg_rpc_use_ssl replaces sahara_rabbitmq_use_ssl - sahara_oslomsg_rpc_userid replaces sahara_rabbitmq_userid - sahara_oslomsg_rpc_vhost replaces sahara_rabbitmq_vhost - sahara_oslomsg_notify_servers replaces sahara_rabbitmq_telemetry_servers - sahara_oslomsg_notify_port replaces sahara_rabbitmq_telemetry_port - sahara_oslomsg_notify_use_ssl replaces sahara_rabbitmq_telemetry_use_ssl - sahara_oslomsg_notify_userid replaces sahara_rabbitmq_telemetry_userid - sahara_oslomsg_notify_vhost replaces sahara_rabbitmq_telemetry_vhost

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