# 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

Non-RT RIC can be also deployed in a Kubernetes cluster, it/dep repository. hosts deployment and integration artifacts. Instructions and helm charts to deploy the Non-RT-RIC functions in the OSC NONRTRIC integrated test environment can be found in the ./nonrtric directory.
