We have described the installation procedure prior to Casablanca, and we now turn to the procedure beginning in Casablanca. As we mentioned earlier, OpenDaylight is configured in Casablanca to install the CCSDK features upon booting up rather than afterwards in a bash script, and "component meta-features" are used rather than the individual features. OpenDaylight boots up much more quickly using this procedure. Features to install at boot time are configured in $ODL_HOME/etc/org.apache.karaf.features.cfg in two parameters: featuresRepositories and featuresBoot. We begin by looking in the Dockerfile for the starting point for the CCSDK container in ccsdk/distribution/odlsli/src/main/docker/Dockerfile Dockerfile for the FROM IMAGE of the CCSDK container (master branch, 8/25/2018): onap/ccsdk-odl-oxygen-image:*{project.version)."

In "onap/ccsdk-odl-oxygen-image," the file $ODL_HOME/etc/org.apache.karaf.features.cfg sets these values for the two startup parameters:
- featuresRepositories = file:${karaf.home}/etc/290021b0-51f7-4e02-8efa-007cad16f73a.xml
- featuresBoot = 0af5d86a-980c-48a9-a02d-bdac71ff8529
...
These universally unique identifiers (UUIDs) are used to identify the startup features. featuresRepositories references the file $ODL_HOME/etc/290021b0-51f7-4e02-8efa-007cad16f73a.xml, shown here.

The And the featuresBoot value of 0af5d86a-980c-48a9-a02d-bdac71ff8529 references the name of the feature in the xml file and pulls in all of the features and bundles included in that file. After logging into a running docker container of the ODL oxygen image, we see that these relatively few features are installed.

This is the starting point for the CCSDK image. Recall that the Dockerfile for the CCSDK image contains these commands:
| No Format |
|---|
RUN cat $ODL_HOME/etc/org.apache.karaf.features.cfg.orig | sed -e "\|featuresRepositories|s|$|, ${CCSDK_SLI_CORE_REPO}, ${CCSDK_SLI_ADAPTORS_REPO}, ${CCSDK_SLI_NORTHBOUND_REPO}, ${CCSDK_SLI_PLUGINS_REPO}|" > $ODL_HOME/etc/org.apache.karaf.features.cfg

These commands append new repositories to featuresRepositories
