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