Goodbye World

The next step after Creating an Instance of SDNR and Creating and Installing a New Feature into SDNR is to create a "component meta-feature" that groups the SDNR features together and enables them to be installed into OpenDaylight using a single reference.  The first step is to create a second feature (Goodbye World) in the same repository as Hello World, shown here.

Executing 'mvn clean install' in these two features generates the corresponding features and zip files in the local maven repository.

These are the key files used by ccsdk/distribution/odlsli/pom.xml to construct the docker container.

The component meta-feature "features" directory

The next step is to move up one level in the directory structure and create a features director with this structure and content.

We discuss each file and folder in turn, beginning with features/pom.xml.

ccsdk-features-sdnr-northbound-all

Most of the work in done in the ccsdk-features-sdnr-northbound-all module.  Its pom file is shown here.

Installer pom.xml file

Now we look at features/installer/pom.xml.  The file is very similar to the pom.xml file for the sliapi installer, although it is simpler because it does not include the "pre-Casablanca" code.  Its dependency is the sdnr-northbound-all artifact created immediately above, and it copies the maven repositories of all the features.xml files with the groupId org.onap.ccsdk.features.sdnr.northbound.

mvn clean install

We now execute 'mvn clean install' and see the output.  As a reminder, this is the initial state of the features directory.

And this shows the critical files afterwards: feature.xml and sdnr-northbound-all-0.3.0-SNAPSHOT-repo.xml.

Here is the content of the zip file, which is the maven repository for the generated features.xml file.

And here is the content of the features.xml file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<features xmlns="http://karaf.apache.org/xmlns/features/v1.4.0" name="sdnr-northbound-all">
     <repository>mvn:org.onap.ccsdk.features.sdnr.northbound/sdnr-helloworld/0.3.0-SNAPSHOT/xml/features</repository>
     <repository>mvn:org.onap.ccsdk.features.sdnr.northbound/sdnr-goodbyeworld/0.3.0-SNAPSHOT/xml/features</repository>
     <feature name="sdnr-northbound-all" description="ccsdk-features-sdnr-northbound :: features :: sdnr-northbound-all" version="0.3.0.SNAPSHOT">
     <details>Root POM to be used in place of odlparent for CCSDK based projects</details>
     <feature version="0.3.0.SNAPSHOT" prerequisite="false" dependency="false">sdnr-helloworld</feature>
     <feature version="0.3.0.SNAPSHOT" prerequisite="false" dependency="false">sdnr-goodbyeworld</feature>
     </feature>
</features>

And the local maven repository has been updated with these files.

We have all of the information that we need.

Modifying Construction of the ODLSLI Container

Two files need to be modified

ccsdk/distribution/odlsli/pom.xml

ccsdk/distribution/odlsli/src/main/docker/Dockerfile


Smoke Test

Now that everything is in place, we can execute the pom.xml file in ccsdk/distribution/odlsli.

Success!  And to show that it actually works.
