When a service is enabled on multiple roles, the parameters for the service will be global. This change enables an option to provide role specific parameter to services and other templates. Two new parameters - RoleName and RoleParameters, are added to the service template. RoleName provides the role name of on which the current instance of the service is being applied on. RoleParameters provides the list of parameters which are configured specific to the role in the environment file, like below: parameters_default: # Default value for applied to all roles NovaReservedHostMemory: 2048 ComputeDpdkParameters: # Applied only to ComputeDpdk role NovaReservedHostMemory: 4096 In above sample, the cluster contains 2 roles - Compute, ComputeDpdk. The values of ComputeDpdkParameters will be passed on to the templates as RoleParameters while creating the stack for ComputeDpdk role. The parameter which supports role specific configuration, should find the parameter first in in the RoleParameters list, if not found, then the default (for all roles) should be used.
