Launching CCSDK
SDN-R is an extension of CCSDK (Common Controller Software Development KIt), and SDN-R uses the same procedure as CCSDK to create a running instance. To begin, clone the ccsdk/distribution repository and look at the docker-compose.yml file in ccsdk/distribution/src/main/yaml.
The file is shown below with annotations (master branch, July 25, 2014). It creates a running instance of CCSDK that is made up of three containers:
- db: standard MySQL container
- odlsli: OpenDaylight with Service Logic Interpreter features installed
- dgbuilder: Directed Graph builder
Here are annotated contents of that file (master branch July 25, 2018, version 0.3.0-SNAPSHOT).
Executing this docker-compose.yml file will create and launch the containers. Navigate to <path>/ccsdk/distribution/src/main/yml and enter the commands as in the sample terminal session below (the credentials to login to NEXUS_DOCKER_REPO are docker:docker). If you are executing this command for the first time, you will see output as the images are downloaded and extracted.

Concurrently, in an other terminal session, you can observe the progress of the launching of the CCSDK containers by using the command 'docker-compose logs -f,' which is similar to a 'tail -f' command.

You can browse to the OpenDaylight apidoc/explorer. Note that port 8383 in the host is forwarded to port 8181 in the odlsli container, and the credentials are not the usual "admin:admin." The password is shown below in the annotated startODL.sh file below.
Working with the CCSDK containers
You can work with the CCSDK containers as you would any docker container, for example:

The entrypoint script for the odlsli container
The entrypoint script for the odlsli container is /opt/onap/ccsdk/bin/startODL.sh. Here is the home directory and bin directory for the user ccsdk.

Creating the ODLSLI Container
To see how the ODLSLI container is constructed, we look at the pom.xml file in the directory ccsdk/distribution/odlsli.
The ~/git/ccsdk/distribution/odlsli pom.xml file
This pom.xml file contructs the odlsli docker container. We will discuss the file in sections.
ODLSLI pom.xml initialization and dependencies
ODLSLI pom.xml: Build Phases
The pom.xml file has three phases in the default life cycle. They are:
- validate
- org.codehaus.groovy.maven : gmavin-plugin : set the name of the ODLSLI docker image to be used in NEXUS_DOCKER_REPO
- maven-resources-plugin
- goal: copy-resources
- id: copy-dockerfile
- copy Docker file
- from ./src/main/docker/
- to ./target/docker-stage/
- id: copy-scripts
- copy all of the scripts (*.sh files)
- from ./src/main/scripts/
- to ./target/docker-stage/opt/onap/ccsdk/bin/
- id: copy-odl-resources
- copy the files:
org.ops4j.pax.logging.cfg
install_ccsdk.yml
ansible-sources.list
- from ./src/main/resources/
- to ./target/docker-stage/
- copy the files:
- id: copy-config
- copy the file org.ops4j.pax.logging.cfg
- from ./src/main/resources/
- to ./target/docker-stage/
- id: copy-data
- copy all of the MySQL databases (*.dump)
- from ./src/main/resources/
- to ./target/docker-stage/opt/onap/ccsdk/data/
- id: copy-properties
- copy all of the properties files (*.properties)
- from ./src/main/properties/
- to ./target/docker-stage/opt/onap/ccsdk/data/properties/
- id: copy-keystores
- copy all *.jks files
- from ./src/main/stores/
- to ./target/docker-stage/opt/onap/ccsdk/data/stores/
- id: copy-dockerfile
- goal: copy-resources
- generate-sources
- process-sources
ODLSLI pom.xml: Docker Profile
And then, within the "docker" profile, there are two phases to package and push the docker image to NEXUS_DOCKER_REPO
We now see how the karaf features for OpenDaylight are structured so they can be installed and OpenDaylight launched. The next step is to understand how the installation folders in CCSDK_HOME/features are created. A good example is the 'sliapi' feature that is part of the CCSDK_CORE_FEATURES. In the gerrit repository, this code appears in ccsdk/sli/core/sliapi.
The sliapi directory contains the usual directories for a karaf feature with an additional directory "installer." This directory contains the code that creates the installation folder stored in the CCSDK_HOME/features folder in the ODLSLI container.
Taking a look at the pom.xml file.
Inspecting the installer pom.xml file
Below is the annotated pom.xml file. It executes two maven phases: prepare-package and package. Maven executes the prepare-package phase before the package phase, although, in the pom.xml file, the prepare-package code appears after the prepare code. In the annotations, the sequence is indicated by number.
