Introduction

The A&AI Model Loader Service is an application that facilitates the distribution and ingestion of new service and resource models and VNF catalogs from the SDC to the A&AI.

Features

The Model Loader:

registers with the SDC to receive notification events
polls the UEB/DMaap cluster for notification events
downloads artifacts from SDC upon receipt of a distribution event
pushes distribution components to A&AI

VNF Catalog loading

The Model Loader supports two methods for supplying VNF Catalog data for loading into A&AI:

Embedded TOSCA image and vendor data
VNF Catalog data can be embedded within the TOSCA yaml files contained in the CSAR.
VNF Catalog XML files
VNF Catalog data in the form of XML files can be supplied in the CSAR under the path Artifacts/Deployment/VNF_CATALOG

Note: Each CSAR should provide VNF Catalog information using only one of the above methods. If a CSAR contains both TOSCA and XML VNF Catalog information, a deploy failure will be logged and published to SDC, and no VNF Catalog data will be loaded into A&AI

Compiling Model Loader

Model Loader can be compiled by running mvn clean install A Model Loader docker image can be created by running docker build -t onap/model-loader target

Running Model Loader

Push the Docker image to your Docker repository. Pull this down to the host machine.

Create the following directories on the host machine:

./logs
./opt/app/model-loader/appconfig
./opt/app/model-loader/appconfig/auth

You will be mounting these as data volumes when you start the Docker container. For examples of the files required in these directories, see the aai/test/config repository (https://gerrit.onap.org/r/#/admin/projects/aai/test-config)

Populate these directories as follows:

Contents of /opt/app/model-loader/appconfig

The following file must be present in this directory on the host machine:

model-loader.properties

# Always false.  TLS Auth currently not supported 
ml.distribution.ACTIVE_SERVER_TLS_AUTH=false

# Address/port of the SDC
ml.distribution.ASDC_ADDRESS=<SDC-Hostname>:8443

Contents of the /opt/app/model-loader/app-config/auth Directory

The following files must be present in this directory on the host machine:

The certificate used to connected to the A&AI

Start the service:

You can now start the Docker container for the Model Loader Service, e.g:

docker run -d \
	-e CONFIG_HOME=/opt/app/model-loader/config/ \
    -v /logs:/logs \
    -v /opt/app/model-loader/appconfig:/opt/app/model-loader/config \
    --name model-loader \
    {{your docker repo}}/model-loader

where

{{your docker repo}}

is the Docker repository you have published your image to.
