SDC Controller,

CatalogDB Adapter,

CatalogDB

SO shall get the ASD-based CNF package (SDC Service CSAR) from SDC and store its metadata to SO Catalog DB.

Pre Condition:

• SO  SDC Controller, CatalogDB Adapter and CatalogDB component instances are running and ready to get SDC notifications

Post Condition:

• SO Catalog DB contains the ASD-based CNF package metadata and artifacts

• Task: When SO gets a package notification from DMaaP, SO SDC Controller queries SDC for the ASD-based CNF Service CSAR that embeds the ASD-based CNF Resource VF.

• Task: SO distinguishes the ASD-based CNF package based on the package metadata, and stores the ASD-based CNF package metadata and artifacts to SO Catalog DB
  • Resource VF TOSCA.metadata will have the "ASD" entity_definition_type.

API Handler,

RequestDB Adapter,

RequestDB,

SO BPMN Infra, 

AAI

SO shall process ASD model info and decide ASD provisioning flows

Pre Condition:

• SO CatalogDB contains ASD Model metadata
  • Resource VF TOSCA.metadata "ASD" entry_definition_type
• SO Client provides parameters based on the ASD lifecycleParameter list
  • ASD LCM Restful Protocols will be used for request/response messages and protocols (ASD LCM RESTful Protocols for SO CNF Manager ) and its swagger file (ASD LCM RESTful Protocols for SO CNF Manager)

Post Condition:

• CNF Manager receives requests from SO BPMN Infra and processes the requests
• After the CNF Manager process, SO shall update CNF to AAI

• Create & Configures ASD-based CNF workflows
  • Create new BPMN workflows for ASD-based CNF workflows
    • Design to invoke SO CNF Manager
  • Configure SO MacroFlows for ASD-based CNF workflows

Task:

• SO API Handler receives a service (or a la carte) request for ASD-based CNF and stores the request information into the Request DB
  • Note: expect no change

Task: 

• SO BPMN Infra decomposes Service into VF Resource(s) and per VF resource, SO BPMN process resource handling
  • If the VF resource metadata indicates the ASD-based VF, SO shall process ASD-based CNF workflows

Task:

• SO shall create service instance to AAI
  
  • note: leverage AAI schema service; no code impact

Task:

• SO shall delegate ASD-based CNF orchestration to SO CNFM
  • Pass input parameters including ASD reference Id, LifecycleParameter, etc.
  • note: until SO CNFM is ready, use no-opt operations as a place holder

SO CNFM,

ASD Repository,

Helm Artifact Repository,

OOF,

AAI, 

SDNC Adapter,

SDNC,

CDS,

CNF Adapter

SO CNFM shall process ASD-based CNF Lifecycle orchestration

Pre Condition:

• ASD and App onboarding package is stored in the Catalog Repository
• Helm Chart(s) are stored in the Helm Artifact Repository

• AAI shall support CRUDQ of ASD-based CNF Resources

  • Leverage existing AAI APIs
  • Investigate any new AAI APIs for ASD-based CNF Resources (TBD)

Post Condition:

• ASD-based CNF is provisioned by SO CNFM

Note: PoC, ASD external CPDs will not be handled (TBD)

Note: ASD Repository, Helm Artifact Repository, Image Artifact Repository will be handled by another Epic, which is defined in Application Package Distribution 

Task: Create SO CNFM and make it available in ONAP

• Create SO CNFM as an SO sub-component
• Make SO CNFM POD is deployable in OOM
• Register SO CNFM POD to AAI automatically

Task: Support for SO CNFM NBI API Handler

• SO CNFM shall support its NBI REST Apis to handle requests from SO.
  • Create SO CNFM NBI API Handler sub-component based on ASD LCM Restful Protocols swagger (ASD LCM RESTful Protocols for SO CNF Manager)
  • Support CRUDQ REST APIs

Task:

• SO CNFM shall support the capability to process input parameters from SO, and use the deployment parameters from ASD for the CNF deployment. Those deployment parameter values shall correspond to the parameters defined in the "lifecycleParameters" section(s) of the ASD.

Task:

• SO CNFM shall communicate with the ASD Repository to get ASD (descriptor) and artifacts from the ASD repository Manager.

Task:

• SO CNFM shall decompose ASD and get the associated DeploymentItems list
  • Get HelmChart references from the DeploymentItems

Task:

• By leveraging the obtained HelmChart references, SO CNFM shall get associated Helm Charts from the Helm Repository Manager.

Task: Create SO CNFM Instance Database Management

• Create SO CNFM Database tables
• Provides Database Access Objects (DAO) for CRUD for SO CNFM

Task:

• SO CNFM shall support the capability to construct a values file from instance specific parameter values from SO and merge the values with default values from ASD Helm Chart values.
• SO CNFM shall store the generated values file  for an instance to SO CNFM database

Task:

• SO CNFM shall transform ASD cloud artifacts with parameters to K8S resource description (e.g., helm template or helm install --dry-run)

Task:

• SO CNFM shall get placement information by passing K8 resources + ASD' + additional data to the Placement component such as OOF.
  • Note: Use of OOF could be out-of-PoC-Scope (TBD)
  • for PoC, it is allowed to choose predefined K8S Clusters

Task:

• SO CNFM shall make a placement decision based on the decision from the Placement component.

Task:

• Per DeploymentItem, SO CNFM shall send (with cluster id, parameter, cloud artifacts) to the SO CNF Adapter for the connection to K8S plugin(e.g., helm install ...)
  • SO CNF Adapter APIs are being studied. 

Task:

• SO CNFM shall update the CNF instance to AAI, by leveraging AAI APIs

SO Client shall send the A La Carte Request for ASD-based CNF orchestration

(note: E2E support is out of PoC scope)
