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.  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 Dec. 4, 2018).  The current value of the CCSDK_DOCKER_IMAGE_VERSION environment variable can be found in the version manifest file of the ONAP integration repository in the directory integration/version-manifest /src/main/resources/docker-manifest.csv (for releases; docker-manifest-staging for current images).

Executing this docker-compose.yml file will create and launch the containers.  Navigate to <path>/ccsdk/distribution/src/main/yaml 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.

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.

ODLSLI pom.xml initialization and dependencies

Master branch, Nov 7, 2018

ODLSLI pom.xml: Preliminaries and setting the version value of the ODLSLI docker image

ODLSLI pom.xml: Prepare the directories and files for a 'docker build' command

Rather than annotate this section of the pom.xml file - which is straightforward - I summarize the actions in the text below.  The pom.xml file uses three phases in the build life cycle to prepare the directory structure and files in ./target/docker-stage prior to building the docker image.  They are:

  • validate
    • plugin: org.codehaus.groovy.maven : gmavin-plugin (described above)
      • set the version of the ODLSLI docker image to be used in NEXUS_DOCKER_REPO
      • Note: the name of the image is set in the property 'image.name' in the pom.xml properties section.
    • plugin: 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:

            • idmlight.db.mv.db

            • org.ops4j.pax.logging.cfg

            • install_ccsdk.yml

            • ansible-sources.list

          • from ./src/main/resources/ 
          • to ./target/docker-stage/
        • 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/
  • generate-sources
    • plugin: org.apache.maven.plugins : maven-dependency-plugin
      • goal: unpack-dependencies
        • id: "unpack features"
          • unzip all of the dependencies
          • from a local or remote Maven repository
          • to ./target/docker-stage
          • Note: all of the zipped features are rooted at the "system" folder, so they will be unzipped into the proper structure for the OpenDaylight feature repository.
      • goal: unpack
        • id: "unpack dgs"
          • Unzip the zipped artifact org.onap.ccsdk.distribution : platform-logic-installer : ${project.version}
          • from a local or remote Maven repository
          • to ./target/docker-stage/opt/onap/ccsdk/
          • Note: this unzips the artifact into the home directory of user ccsdk in the docker container
  • process-sources
    • plugin: org.codehaus.mojo : exec-maven-plugin
      • goal: exec
        • id: "change shell permissions"
          • This executes the following command in the local computer:
          • find ./target/docker-stage/opt/onap/ccsdk -name "*.sh" -exec chmod +x {} \;
          • I.e., make all of the bash scripts in the ccsdk home directory executable.

ODLSLI pom.xml: Docker Profile

The "docker" profile defines the additional "package" phase in which the docker image is built.  There is also a "deploy" phase in which the generated image is pushed to NEXUS_DOCKER_REPO, but this requires special privileges.  We discuss this section below.

The Dockerfile

We have seen how the pom.xml file creates the ~/ccsdk/distribution/odlsli/target/docker-stage directory in preparation for building the docker image.  The next step is to inspect the Dockerfile that creates the image, discussed here.

Building the docker image

Using maven

One can create the image using the maven command "mvn --activate-profiles docker clean package" or equivalently "mvn -P docker clean package."  This generates these images:

We see that a single image (all have the same IMAGE ID) is given four tags.

Using maven and 'docker build'

By running the command 'mvn clean process-sources' and getting a BUILD SUCCESS, a properly constructed directory will be created at ~/git/ccsdk/distribution/odlsli/target/docker-stage/.

Before building the image, remember that the Dockerfile begins with a local image of OpenDaylight Oxygen: onap/ccsdk-odl-oxygen-image${project.version} (currently 0.3.0-SNAPSHOT).  One can download the image from NEXUS_DOCKER_IMAGE and then rename it as a local image using the commands below.

Remember that the entrypoint script /opt/onap/ccsdk/bin/startODL.sh will execute and that it waits to login to the db server, so SDNR will not progress if it cannot login to the MySQL server.  We want to connect SDNR to ccsdk_db_container, and we inspect the CCSDK containers to learn about their network.

We now have the information we need to start the container, and we use the command described here to launch it.

Alternatively, one can edit the docker-compose.yml file to use the newly created onap/sndr:0.3.0-SNAPSHOT image rather than the ccsdk-odlsli-image pulled from NEXUS_DOCKER_REPO.  That will also create and launch the new SDNR container.

Creating the zip installation files for karaf features

We have seen how the karaf features for CCSDK are included in the dependencies section of the pom.xml file in ~/ccsdk/distribution/odlsli/ and that the features are referenced as files with the name structure <feature-name>-installer.<version>-repo.zip.  The next step is to understand how these zip installation files are created.  A good example is the "sliapi" feature, which is in the gerrit repository ccsdk/sli/core, shown here.

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 zip file that is referenced in the dependencies section of the ODLSLI pom.xml file.

Context for the installer

OpenDaylight Guidelines and Component Meta-Features

CCSDK is based on OpenDaylight and follows the recommended practices of that group.  There are documented guidelines for karaf features, and another aspect is what OpenDaylight calls "component meta-features," in which several related features are grouped together to simplify their installation.  For example, these features implement NETCONF in OpenDaylight:

  • odl-netconf-api

  • odl-netconf-mapping-api

  • odl-netconf-util

  • odl-netconf-impl

  • odl-netconf-netty-util

  • odl-netconf-client

  • odl-netconf-monitoring

Rather than install each feature individually in the karaf client, one can use the component meta-feature "odl-netconf-all" and install all of the features with the single command "feature:install odl-netconf-all."  Recall that the Dockerfile for ccsdk_odlsli_container sets these environment variables:

ENV CCSDK_SLI_CORE_REPO mvn:org.onap.ccsdk.sli.core/ccsdk-sli-core-all/${ccsdk.sli.core.version}/xml/features
ENV CCSDK_SLI_ADAPTORS_REPO mvn:org.onap.ccsdk.sli.adaptors/ccsdk-sli-adaptors-all/${ccsdk.sli.adaptors.version}/xml/features
ENV CCSDK_SLI_NORTHBOUND_REPO mvn:org.onap.ccsdk.sli.northbound/ccsdk-sli-northbound-all/${ccsdk.sli.northbound.version}/xml/features
ENV CCSDK_SLI_PLUGINS_REPO mvn:org.onap.ccsdk.sli.plugins/ccsdk-sli-plugins-all/${ccsdk.sli.plugins.version}/xml/features

So CCSDK has created a component meta-feature for each of the SLI repositories, and we will encounter commands in the Maven pom.xml files and directory and file structures to implement them.

Procedure to install CCSDK features prior to Casablanca

Another aspect for the context of the installer is that CCSDK changed the procedure to install karaf features from Beijing to Casablanca, but some elements of the prior procedure are still present.  Prior to Casablanca, all of the CCSDK features were copied into the CCSDK home directory (/opt/onap/ccsdk) in the folder '/opt/onap/ccsdk/features/,' and the entry point script in the Docker container installed them.  The contents of the CCSDK home directory and features directory for Beijing are shown here.

As we can see, each feature is in a directory with the name "ccsdk-<feature-name>," and the directory contains a zip file with the name "ccsdk-<feature-name>-<version>.zip" and an 'install-feature.sh' script.  The zip file is simply the maven repository for the feature, as shown here for ccsdk-sliapi.

And here is the 'install-feature.sh' script.

Inspecting the installer pom.xml file

Below is the annotated pom.xml file, which executes three maven phases in sequence: validate, prepare-package and package.  However, the commands in the code do not appear in the sequence in which they are executed.  For the sake of clarity, we discuss the commands in the sequence in which are executed.

Installer pom.xml file part 0

install-feature.sh script

As we described in a previous section, the installation folder (<features.boot>) for a particular feature contains the zipped maven repository and an installation script for that feature.  The script is below, and as you can see, it references the <features.respositories> and <features.boot> properties in commands sent to the karaf client.

install-feature.sh
ODL_HOME=${ODL_HOME:-/opt/opendaylight/current}
ODL_KARAF_CLIENT=${ODL_KARAF_CLIENT:-${ODL_HOME}/bin/client}
INSTALLERDIR=$(dirname $0)

REPOZIP=${INSTALLERDIR}/${features.boot}-${project.version}.zip

if [ -f ${REPOZIP} ]
then
        unzip -d ${ODL_HOME} ${REPOZIP}
else
        echo "ERROR : repo zip ($REPOZIP) not found"
        exit 1
fi

${ODL_KARAF_CLIENT} feature:repo-add ${features.repositories}
${ODL_KARAF_CLIENT} feature:install ${features.boot}

Installer pom.xml file part 1

Continuing with the pom.xml file in the installer module, we now discuss the command first executed in the "validate" phase.

To see the result of this command, we show the changes in the installer directory after it is executed.  We begin with 'mvn clean' and then execute part one and show the result.

As expected, install-feature.sh has been copied into target/stage and the parameter values have been inserted into the placeholders.

Installer pom.xml file part 2

Now the command executed in the "prepare-package" phase.

And we show the result of executing the command.

The maven repositories have been copied into installer/target/assembly with the correct structure and properly rooted at system/, although, as mentioned, the artifact "features-sliapi" in not included.

Installer pom.xml part 3

Parts 1 and 2 have copied all of the necessary maven repositories and scripts into the correct folder structure and with the correct parameter values.  The pom.xml file now zips them up.

assemble_mvnrepo_zip.xml

And after it is executed...

The repositories have been properly zipped up into installer/target/stage/ccsdk-sliapi-0.3.0-SNAPSHOT-repo.zip.

Installer pom.xml part 4

And the final step.

assemble_installer_zip.xml

And after it is executed...

Voilà!

Installation in Casablanca

Setting the startup features

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 ccsdk/distribution/odlsli/src/main/docker/Dockerfile for the FROM IMAGE of the CCSDK container (master branch, 8/25/2018)::

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

Startup features in the Dockerfile FROM IMAGE

These universally unique identifiers (UUIDs) identify the startup features.  featuresRepositories references the file $ODL_HOME/etc/290021b0-51f7-4e02-8efa-007cad16f73a.xml, shown here.

root@6cd44c751205:/opt/opendaylight/current/etc# cat $ODL_HOME/etc/290021b0-51f7-4e02-8efa-007cad16f73a.xml

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.

Editing the parameters for the startup karaf features

The above is the starting point for the CCSDK image.  Recall that the Dockerfile for the CCSDK image contains these commands:

ENV ODL_HOME /opt/opendaylight
ENV SDNC_CONFIG_DIR /opt/onap/ccsdk/data/properties
ENV CCSDK_SLI_CORE_REPO mvn:org.onap.ccsdk.sli.core/ccsdk-sli-core-all/${ccsdk.sli.core.version}/xml/features
ENV CCSDK_SLI_ADAPTORS_REPO mvn:org.onap.ccsdk.sli.adaptors/ccsdk-sli-adaptors-all/${ccsdk.sli.adaptors.version}/xml/features
ENV CCSDK_SLI_NORTHBOUND_REPO mvn:org.onap.ccsdk.sli.northbound/ccsdk-sli-northbound-all/${ccsdk.sli.northbound.version}/xml/features
ENV CCSDK_SLI_PLUGINS_REPO mvn:org.onap.ccsdk.sli.plugins/ccsdk-sli-plugins-all/${ccsdk.sli.plugins.version}/xml/features
...
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
RUN echo featuresBoot=config,standard,region,package,kar,ssh,management,odl-restconf-all,odl-mdsal-all,odl-mdsal-apidocs,odl-daexim-all,ccsdk-sli-core-all,ccsdk-sli-adaptors-all,ccsdk-sli-northbound-all,ccsdk-sli-plugins-all >> $ODL_HOME/etc/org.apache.karaf.features.cfg

These commands append new repositories to featuresRepositories and set featuresBoot to the desired feature names. (Note: the final content of the file is not what I expect from these commands, but the objective is achieved, i.e., the parameters are set to the correct values.)  We inspect the features.xml file for the repository containing our example feature sliapi.

ENV CCSDK_SLI_CORE_REPO mvn:org.onap.ccsdk.sli.core/ccsdk-sli-core-all/${ccsdk.sli.core.version}/xml/features

We see that the component meta-feature ccsdk-sli-core-all contains the repository and name for all of the features in the ccsdk/sli/core repository, including sliapi.

Constructing the component meta-feature

To see how the ccsdk-sli-core-all is constructed, we inspect the features directory in ccsdk/sli/core.

The pom.xml file of interest is features/ccsdk-sli-core-all/pom.xml, which we show here in its entirety.

We see that it includes dependencies for the feature.xml file for each feature in the ccsdk/sli/core repository and generates the feature.xml file (packaging>feature</packaging>) for ccsdk-sli-core-all.  I believe that all of the other folders in ccsdk/sli/core/features are vestigial or - at least - uninvolved in the installation of features in ccsdk_odlsli_container.
