Stein Series Release Notes¶

18.0.0.0b1-146¶

The service updates for keystone will now be executed through delegation to the keystone_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.
```
keystone_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 keystone_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 keystone.

The tasks creating a keystone service user have been removed, along with related variables keystone_service_user_name and keystone_service_password. This user can be deleted in existing deployments.

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

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

The rabbitmq server parameters have been replaced by corresponding oslo.messaging RPC and Notify parameters in order to abstract the messaging service from the actual backend server deployment. - keystone_oslomsg_rpc_servers replaces keystone_rabbitmq_servers - keystone_oslomsg_rpc_port replaces keystone_rabbitmq_port - keystone_oslomsg_rpc_use_ssl replaces keystone_rabbitmq_use_ssl - keystone_oslomsg_rpc_userid replaces keystone_rabbitmq_userid - keystone_oslomsg_rpc_vhost replaces keystone_rabbitmq_vhost - keystone_oslomsg_notify_servers replaces keystone_rabbitmq_telemetry_servers - keystone_oslomsg_notify_port replaces keystone_rabbitmq_telemetry_port - keystone_oslomsg_notify_use_ssl replaces keystone_rabbitmq_telemetry_use_ssl - keystone_oslomsg_notify_userid replaces keystone_rabbitmq_telemetry_userid - keystone_oslomsg_notify_vhost replaces keystone_rabbitmq_telemetry_vhost

The default TLS verion 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 keystone_ssl_protocol variable.

The conditional that determines whether the sso_callback_template.html file is deployed for federated deployments has been fixed.

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