ONAP artifacts descriptions
Describes ONAP artifacts used in various scenarios in this document.
DCAE blueprint
- used in SDC to describe AC
- TOSCA-based (YAML)
- artifact name needs to end with event_proc.bp
- example name: dcae_blueprint.event_proc_bp.yaml
- example name: dcae_blueprint.event_proc_bp.yaml

}Micro-service policy (instance)
Configured micro-service policy. In this case Clamp is creating it using Policy API.
e.g. in Beijing TCA configuration Micro-service policy contains information about metrics and tresholds
Operational policy (instance)
Policy with configured Drools Rule. In this case Clamp is creating it using Policy API.
e.g. in Beijing this policy decided whether to start APPC LCM or not.
Current control loop design and execution
Stages required to run control loop:
AC blueprint design (SDC)
AC blueprint distribution (SDC)
CL configuration (CLAMP)
CL submit (CLAMP)
CL deploy (CLAMP)
Desired control loop design and execution
Stages required to run control loop:
Deployment Artifact design using SDC DCAE-D
In this step user should design and add to service 2 deployment artifacts:
AC blueprint (DCAE_BLUEPRINT)
Policy model (example: policy.yaml)
Distribution of CSAR containing Policy model and AC blueprint (SDC)
- Both Policy and Clamp should receive Artifact distribution notification.
- Both Policy and Clamp should receive Artifact distribution notification.
AC configuration (CLAMP)
- Policy should extract logic of creating forms for configuring Policy using micro-service policy schema (in this confluence it's called Policy SDK)
- Clamp should use Policy SDK to create generic form out of saved micro-service policy schema.
Action Policy configuration (CLAMP)
CL submit (CLAMP)
CL deploy (CLAMP)
