Stein Series Release Notes¶

18.0.0.0b1-77¶

The service setup in keystone for aodh will now be executed through delegation to the aodh_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.
```
aodh_service_setup_host: "{{ groups['utility_all'][0] }}"
```

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 aodh_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 aodh.

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

The log path, /var/log/aodh is no longer used to capture service logs. All logging for the aodh service will now be sent directly to the systemd journal.

The rabbitmq server parameters have been replaced by corresponding oslo.messaging RPC and Notify parameters in order to abstract the messaging service from the actual backend server deployment. - aodh_oslomsg_rpc_servers replaces aodh_rabbitmq_servers - aodh_oslomsg_rpc_port replaces aodh_rabbitmq_port - aodh_oslomsg_rpc_use_ssl replaces aodh_rabbitmq_use_ssl - aodh_oslomsg_rpc_userid replaces aodh_rabbitmq_userid - aodh_oslomsg_rpc_vhost replaces aodh_rabbitmq_vhost - aodh_oslomsg_rpc_password replaces aodh_rabbitmq_password

When running aodh with apache(httpd) all apache logs will be stored in the standard apache log directory which is controlled by the distro specific variable aodh_apache_default_log_folder.
