This howto is still work in progress.

It is sometimes convenient to have a local installation of DMaaP on your machine for testing purposes. For example, for testing policies, you can connect the Policy Framework to a local installation of DMaaP and use curl to issue the policy REST calls to the local DMaaP. For this howto, in order to avoid a dependency on A&AI, checks towards A&AI are commented out. This howto was written on the Amsterdam versions of DMaaP. It was executed on a Macbook Pro running macOS 10.13.3.

...

  1. Create a new directory, let's call it "local-dmaap", and go into the directory

    Code Block
    languagebash
    mkdir <path-to>/local-dmaap
    cd  <path-to>/local-dmaap
  2. Clone the DMaaP msgrtr and messageservice repositories

    Code Block
    languagebash
    git clone https://gerrit.onap.org/r/dmaap/messagerouter/msgrtr
    git clone https://gerrit.onap.org/r/dmaap/messagerouter/messageservice
  3. Check out the Amsterdam branches of the DMaaP repos

    Code Block
    cd msgrtr
    git co amsterdam
    cd ../messageservice
    git co amsterdam
    cd ..
  4. In order to remove the need to install A&AI, comment out as follows in msgrtr src/main/java/com/att/nsa/cambria/service/impl/TopicServiceImpl.java:

  5. Build the msgrtr, skipping tests if you wish. Once the build completes, we're finished in msgrtr.

    Code Block
    languagebash
    cd msgrtr
    mvn clean install
  6. In messageservice, the start-kafka.sh script breaks with the latest version of Scala and Kafka unless a new line is added to the end of the server.properties file. Edit the messageservice src/main/resources/docker-compose/start-kafka.sh as follows:

  7. Ensure that the version of msgrtr dependency used in messageservice pom.xml is the local one created above, check your pom.xml in messageservice, specifically you must specify if msgrtr is a SNAPSHOT version. for example, see below:

    Build the message service, skipping tests if you wish.

    Code Block
    languagebash
    mvn clean install
  8. Ensure Docker is running on your machine. Clear down all relevant containers and images in your docker that might interfere with DMaaP. Use the commands below WITH CARE!

    Code Block
    docker ps -a | cut -f1 -d' ' | awk '{printf("docker rm %s\n", $1)}'
    docker images | cut -c45-60 | grep -v ubuntu | awk '{printf("docker rmi --force %s\n", $1)}'
  9. In messageservice, copy the "appl" directory to target/classes/docker. This copies the configuration for DMaaP into the location in which we will build the docker images and the docker-compose setup.

    Code Block
    pwd local-dmaap/messageservice
    cp -pr target/swm/package/nix/dist_files/appl target/classes/docker
  10. If /var/tmp/MsgRtr.properties file or directory exists on /var/tmp,delete it. This is the file where we will specify the local properties for Kafka/Zookeeper for DMaaP.

  12. Build the msgrtr, skipping tests if you wish. Once the build completes, we're finished in msgrtr.

    Code Block
    languagebash
    cp bundleconfig-local/etc/appprops/MsgRtrApi.properties /var/tmp
    Edit /var/tmp/MsgRtrApi.properties as follows to put in the host names and ports for Kafka and Zookeeper in our docker-compose setup
    cd msgrtr
    mvn clean install
  13. In messageservice, the start-kafka.sh script breaks with the latest version of Scala and Kafka unless a new line is added to the end of the server.properties file. Edit the messageservice src/main/resources/docker-compose/start-kafka.sh as follows:

    Code Block

    < kafka.metadata.broker.list=<kafka_host>:<kafka_port>
    ---
    > kafka.metadata.broker.list=kafka:9092
  14. Now we prepare to build the Docker image for the DMaaP message service. Edit the messageservice startup.sh script as shown below, replacing all occurrences of "${project.artifactId}" with "dmaapMR1" and all occurrences of "${ajscRuntimeVersion}" with "1.0.0"

    Code Block
    languagebash
    cd target/classes/docker
    diff startup.sh.orig startup.sh 
    22,24c22,24

    < runner_file="appl/${project.artifactId}/lib/ajsc-runner-${ajscRuntimeVersion}.jar"
    ---
    > root_directory="/appl/dmaapMR1"
    > config_directory="/appl/dmaapMR1/bundleconfig"
    > runner_file="appl/dmaapMR1/lib/ajsc-runner-1.0.0.jar"
  15. Build the adapted DMaaP docker image, it will be tagged as dmaap:localadapt

    Code Block
    languagebash
    docker build -t dmaap:localadapt .
  16. Now we prepare the docker-compose setup for DMaaP. Go to messageservice/target/classes/docker-compose and edit Dockerfile, changing the KAFKA_VERSION to 1.0.0 and the SCALA_VERSION to 2.12

    Code Block
    cd ../docker-compose
    diff Dockerfile.orig Dockerfile

    ---
    > ENV KAFKA_VERSION="1.0.0" SCALA_VERSION="2.12"
    
  17. Edit docker-compose.yml to change the name of th DMaaP docker image to use our locally adapted DMaaP image:

    Code Block
    languagebash
    diff docker-compose.yml.orig docker-compose.yml 
    21c21
    <     image: attos/dmaap
    ---
    >     image: dmaap:localadapt
  18. On macOS only, edit docker-compose.yml to change var/tmp to /private/var/tmp (ensure you have /private/var/tmp shared with Docker on macOS).

  19. Start DMaaP, crossing your fingers really tightly!

    Code Block
    languagebash
    docker-compose up
  20. Check that DMaaP is running with a curl request to list topics

    Code Block
    languagebash
    curl  --request GET localhost:3904/topics
    {"topics": []}
  21. Create a topic called MyTpoic

    Code Block

        --request POST \

  23. Build the message service, skipping tests if you wish.

    cp -pr target/swm/package/nix/dist_files/appl target/classes/docker
  26. In messageservice, copy the "startup.sh" script target/classes/docker. This is the startup shell script for the DMaaP message service in Docker.

    Code Block
    cp target/swm/package/nix/dist_files/startup.sh target/classes/docker
  27. If /var/tmp/MsgRtr.properties file or directory exists on /var/tmp,delete it. This is the file where we will specify the local properties for Kafka/Zookeeper for DMaaP.

    Code Block
    languagebash
    rm -fr /var/tmp/MsgRtrApi.properties
  28. Copy the template MsgRtr properties to /var/tmp

    Code Block
    languagebash
    cp bundleconfig-local/etc/appprops/MsgRtrApi.properties /var/tmp
  29. Edit /var/tmp/MsgRtrApi.properties as follows to put in the host names and ports for Kafka and Zookeeper in our docker-compose setup:

    Code Block
    languagebash

  30. Build the adapted DMaaP docker image, it will be tagged as dmaap:localadapt

    Code Block
    languagebash
    cd target/classes/docker
    docker build -t dmaap:localadapt .
  31. Now we prepare the docker-compose setup for DMaaP. Go to messageservice/target/classes/docker-compose and edit Dockerfile, changing the KAFKA_VERSION to 1.0.0 and the SCALA_VERSION to 2.12

    Code Block
    cd ../docker-compose

  32. Edit docker-compose.yml to change the name of th DMaaP docker image to use our locally adapted DMaaP image:

    Code Block
    languagebash
    diff docker-compose.yml.orig docker-compose.yml 
    21c21
    <     image: attos/dmaap
    ---
    >     image: dmaap:localadapt
  33. On macOS only, edit docker-compose.yml to change var/tmp to /private/var/tmp (ensure you have /private/var/tmp shared with Docker on macOS).

  34. Start DMaaP, crossing your fingers really tightly!

    Code Block
    languagebash

  35. Check that DMaaP is running with a curl request to list topics

    Code Block
    languagebash

    ANSWER
    {"topics": []}
  36. Create a topic called MyTopic
