Design

Step 1: Design the Control Loop Flow in SDC (DCAE-Design Studio or manually)

Design the Service and deploy it to clamp by logging to the portal:

http://portal.api.simpledemo.onap.org:8989/ONAPPORTAL/login.htm

What will be the scope of control loop flows in Casablanca:

Which microservices will be used ?
TCA, Holmes (Can be configured in CLAMP and based on pattern matching in the Blueprint)
Will flows contain more than one microservice node?
No
Will microservices be capable of receiving more than one configuration policy
None
Will the singleton vs. dynamically deployed distinction be described in the TOSCA?
No
Will collectors be deployed dynamically or statically?
Statically, the VES collector is deployed in DCAE
Will DCAE Design Studio allow for the piecing together of flows in Casablanca?
Which blueprint can be uploaded to SDC ? (Examples)

Blueprint for TCA on OOM

Step 2: Distribute artifacts

CLAMP videos#DistributiontoCLAMP

The artifact distribution must be done from SDC to CLAMP, in order to distribute the Blueprint and service/VF associated.

This will create Closed Loops associated to VF and Service in Clamp database

Step 3: CLAMP Processes artifact

Parsing of the SDC notification is done by CLAMP and is based on string patterns found in the Blueprint.

Only Holmes and TCA are currently supported by default, but this can be customized by the Clamp config files.

The default config file is bundled in the JAR: src/main/resources/clds/templates/blueprint-parser-mapping.json

But this can be overridden by specifying the spring config "clamp.config.sdc.blueprint.parser.mapping" in clamp.env for docker-compose (set by default to "classpath:/clds/blueprint-parser-mapping.json")

Configure

Configure the Closed Loop in the CLAMP UI

A Certificate must be added in the browser and is required to login properly

org.onap.clamp.p12 (from master) (Password: "China in the Spring")

The Closed loop created by the SDC distribution can be opened in the CLAMP UI . The Guard/Operational and configuration policies must be configured in the UI.

Once done, the closed loop can be submitted to Policy by clicking on Manage → Submit
