Developer Guide

This document provides a quickstart for developers of the Non-RT RIC DME Participant.

Additional developer guides are available on the O-RAN SC NONRTRIC Developer wiki.

The DME Participant is a Java 17 web application built using the Spring Framework. Using Spring Boot dependencies, it runs as a standalone application.

Its main functionality is to work with ACM to lifecycle manage DME.

Start standalone

The project uses Maven. To start the DME Participant as a freestanding application, run the following command in the rappmanager/participants/participant-impl-dme directory:

mvn spring-boot:run

There are a few service endpoints that needs to be available to run. These are referred to from the application.yaml file. The following properties have to be modified:

• dme.baseUrl=http://informationservice:9082

Start in Docker

To build and deploy the DME Participant, go to the rappmanager/participants/participant-impl-dme folder and run the following command:

mvn clean install

Then start the container by running the following command:

docker run nonrtric-plt-dmeparticipant

Kubernetes deployment

The Non-RT RIC rApp Manager can be also deployed as part of an Integrated SMO in a Kubernetes cluster, and instructions can be found in the OSC it/dep repository, particularly in the ./smo-install directory.

For more information on installation of Non-RT RIC and SMO components in Kubernetes, see Deploy NONRTRIC functions in Kubernetes.

For more information see Integration and Testing documentation in the O-RAN-SC.
