With Model Driven Control Loop feature, Policy is migrating toward new design/architecture in Dublin. This requires interfacing clients (CLAMP, DCAE) to use new LC API’s and onboarding MS to use new tosca policy model. As automated generation of models and distribution between SDC and Policy is deferred to next release, certain manual steps will be required in Dublin. The steps below should be followed by any DCAE MS targeted under CL flows deployed through CLAMP.

Type Creation (Development phase)
- Create the MS specific blueprint, component_spec and associated data_format based on DCAE team specification (refer to details under DCAE wiki page - Dublin Deployment Strategy).
Note: For components with dynamic configuration, the component spec MUST include policy schema definition (policy_editable set for required parameter exposed via policy with corresponding policy_schema defined) - Use SDC/ToscaLab tool as documented here to create the base policy model
Note: If the policy model does not get generated, change the "component_type" from "docker" to "cdap" in the componentspec and retry policy model creation.
The base policy model created by the tool is not compliant to R4 model expected by Policy; following updates will be required.
