SDC supports the App Onboarding Package, which is compliant to the ETSI NFV SOL004 CSAR structure with the TOSCA-Metadata directory

• Supports the ETSI NFV SOL004 version ?? (3.3.1, 2.7.1, 2.6.1 and 2.5.1)
• For SDC onboarding, Supports the App package has the TOSCA-Metadata directory and the following metadata
  • Reuse the same metadata structure defined by TOSCA and ETSI
  • Reuse the same ETSI defined Entry keywords; only requires ETSI-Entry-Manifest
• Supports the ASD_types.yaml which defines Application Service Descriptor (ASD) in TOSCA
• In the main manifest file, reuse the metadata structure defined by ETSI with new keywords. 
• By using the new metadata, SDC supports the following new manifest metadata, which will be used by the orchestrators to distinguish the package is for App and based on ASD
  
  • application_name
  • application_provider
  • release_date_time
  • entry_definition_type: [asd]

SDC creates an SDC VSP package thru onboarding of an Application Service CSAR based on ASD

• SDC copies the contents of TOSCA.meta metadata from the onboarding App package TOSCA.meta
• SDC maps ASD to ONAP internal model in SDC VSP
  • Design suggestion: ASD ↔ ONAP VF, DeploymentItems ↔ VF-Modules
  • If VSP model can be ignored, this mapping can be skipped
• SDC generates the GlobalSubstitutionTypesServiceTemplate.yaml by including the app_main_descripter.mf information
• SDC generates Artifacts directory by copying artifacts from the onboarding App package
  • SDC should copy all the onboarding artifacts to VSP
• SDC preserves the original onboarding App package in the Deployment directory
• SDC should be able to handle large-size image files. SDC stores the image files to the Kubernetes Object Storage temporarily and waits for the Runtime Catalog Manager picks up and stores the images files to the Image repository
• SDC preserves the original onboarding TOSCA.meta (rename TOSCA.meta.original) in the TOSCA-Metadata
• SDC uses the Artifacts > HELM directory to hold the onboarding Helm Charts

SDC creates AS internal CSAR (VF resource) by importing VSP CSAR to add CNF/Application based on ASD

• SDC generates TOSCA-Metadata directory and TOSCA.meta for ASD package
  • entry_defintion_type in the ASD package will be copied into TOSCA.meta
• SDC maps the onboarding ASD models into the ONAP internal model
  • Design suggestion: ASD ↔ ONAP VF, DeploymentItems ↔ VF-Modules
  • see the mapping, MappingbetweenASDandSDCInternalModel 
  • extend the org.openecomp.groups.VfModule to hold the DeploymentItems properties, such as deployment_order and lifecycl parameters Note: SO CNFM can read the properties from ASD.
• SDC generates resource-<...>-template and template-interface models based on the onboarding ASD model
• SDC preserves the original onboarding App package and adds additional License files thru SDC UI
• SDC uses the Artifacts > HELM directory to hold the onboarding Helm Charts
• SDC UI should be able to modify some of ASD property values
  • SDC UI populates lifecycleManagement values as needed
  • If values.schema.json files exist, SDC UI validates values.yaml files and populate customizable values

Create an Service CSAR consists of one or more CNF/Application based on ASD

• SDC generates TOSCA-Metadata directory and TOSCA.meta
• SDC maps the onboarding ASD models into the ONAP internal models
• SDC uses the "HELM" directory under the Artifacts to contain Helm Charts

SDC distributes Service CSAR to ONAP runtime components thru DMaaP

• Assuming no SDC impact for this 

For the App Package notification, ONAP Runtime Catalog Manager queries from SDC and stores associated Helm Charts and Images to the target Helm and Image Artifact Repositories

• Get Helm Charts from the Helm directory and stores the target Helm Artifact Repository
• Get Images from the Object Storage and stores the target Image Artifact Repository
