This tutorial shows how you can test your custom feature by creating and starting a minimal distribution. As example we will do it for the o-ran-sc for a o-ran radio unit front haul(ru-fh) devicemanager for ONAP Frankfurt.
Odl feature
To create an odl/ONAP feature you have to create at least three parts:
- provider with your code
- feature which defines the odl bundles to startup
- installer which brings the artifacts into the container
A good example is the SDN-R helpserver which has only these parts or the o-ran ru-fh devicemanager.
Distribution
To create a distribution within our custom feature based on sdnc-image we need three files.
├── pom.xml ├── src │ └── main │ ├── docker │ │ └── Dockerfile │ └── scripts │ └── TagVersion.groovy

package org.oransc.oam.distribution def versionArray; if ( project.properties['o-ran-sc.project.version'] != null ) { versionArray = project.properties['o-ran-sc.project.version'].split('\\.'); } if ( project.properties['o-ran-sc.project.version'].endsWith("-SNAPSHOT") ) { patchArray = versionArray[2].split('-'); project.properties['project.docker.latestminortag.version']=versionArray[0] + '.' + versionArray[1] + "-SNAPSHOT-latest"; project.properties['project.docker.latestfulltag.version']=versionArray[0] + '.' + versionArray[1] + '.' + patchArray[0] + "-SNAPSHOT-latest"; project.properties['project.docker.latesttagtimestamp.version']=versionArray[0] + '.' + versionArray[1] + '.' + patchArray[0] + "-SNAPSHOT-"+project.properties['ccsdk.build.timestamp']; } else { project.properties['project.docker.latestminortag.version']=versionArray[0] + '.' + versionArray[1] + "-STAGING-latest"; project.properties['project.docker.latestfulltag.version']=versionArray[0] + '.' + versionArray[1] + '.' + versionArray[2] + "-STAGING-latest"; project.properties['project.docker.latesttagtimestamp.version']=versionArray[0] + '.' + versionArray[1] + '.' + versionArray[2] + "-STAGING-"+project.properties['ccsdk.build.timestamp']; }

The only thing you have to do is to manipulate the properties and the dependencies in the pom.xml.
- base-image: on which you want to run your custom feature
- o-ran-sc.features: which is the feature repo you have to add (should look like this mvn:org.something.more/myartifact-feature/version/xml/features
- features.boot: which will add the features to the odl boot features on startup
- and you have to add the dependency (in this case devicemanager-oran-ru-fh-installer) to inject the artifacts into the container during build process.
