--- deprecations: - | The static role definitions contained a number of conflicting parameters which require special handling to convert to dynamic template generation. In the future, these parameters will be removed. If a role requires one of these deprecated parameters, then it will be defined in the role definition in a property named "deprecated_param_". If the role has one or more deprecated parameters, then "uses_deprecated_params" should be set to True as well. This will enable creation of a parameter_group containing the deprecated parameters in the role definition, which will enable warning users if they use deprecated parameters on deployment. upgrade: - | For deployments where a custom roles_data file is used, it should be rebased against the default roles_data.yaml, as several additional items, e.g to specify deprecated parameter names for some of the default roles, have been added. Alternatively you can regenerate your roles_data using the new overcloud roles generate command, so that the updated role definitions in /usr/share/openstack-tripleo-heat-templates/roles are used, which include the necessary additional data.
