Dockerfiles for WSO2 Stream Processor

This section defines Dockerfiles and step-by-step instructions to build Docker images for product profiles provided by WSO2 Stream Processor 4.0.0, namely :

  1. Dashboard
  2. Editor
  3. Manager
  4. Worker
  5. Kafka

How to build the WSO2 Stream Processor images and run

1. Checkout this repository into your local machine using the following Git command.
git clone https://github.com/wso2/docker-sp.git

The local copy of the dockerfiles directory will be referred to as DOCKERFILE_HOME from this point onwards.

2. Copy the extract JDK and WSO2 Stream Processor distributions to <DOCKERFILE_HOME>/base/files
3. Download MySQL Connector/J v5.1.45 and copy the jar to <DOCKERFILE_HOME>/base/files
cp path/to/mysql/connector/jar <DOCKERFILE_HOME>/base/files
4. Convert and copy the Kafka client jars from the kafka_2.11-0.10.0.0/libs/ to <DOCKERFILE_HOME>/base/files directory

The list of required client jars are;

  • kafka_2.11-0.10.2.1.jar
  • kafka-clients-0.10.2.1.jar
  • metrics-core-2.2.0.jar
  • scala-library-2.11.8.jar
  • scala-parser-combinators_2.11-1.0.4.jar
  • zkclient-0.10.jar
  • zookeeper-3.4.9.jar

Use the jartobundle.sh script found it wso2sp-4.0.0/bin as shown below; note that you will have to run this command for each jar mentioned above

./wso2sp-4.0.0/bin/jartobundle.sh path/to/kafka/client/jar <DOCKERFILE_HOME>/base/files
4. Build the base Docker image.
  • For base, navigate to <DOCKERFILE_HOME>/base directory.
    Execute docker build command as shown below.
    • docker build -t wso2sp-base:4.0.0 .
5. Build Docker images specific to each profile.
  • For Dashboard, navigate to <DOCKERFILE_HOME>/dashboard directory.
    Execute docker build command as shown below.
    • docker build -t wso2sp-dashboard:4.0.0 .
  • For Editor, navigate to <DOCKERFILE_HOME>/editor directory.
    Execute docker build command as shown below.
    • docker build -t wso2sp-editor:4.0.0 .
  • For Manager, navigate to <DOCKERFILE_HOME>/manager directory.
    Execute docker build command as shown below.
    • docker build -t wso2sp-manager:4.0.0 .
  • For Worker, navigate to <DOCKERFILE_HOME>/worker directory.
    Execute docker build command as shown below.
    • docker build -t wso2sp-worker:4.0.0 .
6. Running Docker images specific to each profile.
  • For Dashboard,
    • docker run -it -p 9643:9643 wso2sp-dashboard:4.0.0
  • For Editor,
    • docker run -it -p 9390:9390 -p 9743:9743 wso2sp-editor:4.0.0
  • For Manager,
    • docker run -it wso2sp-manager:4.0.0
  • For Worker,
    • docker run -it wso2sp-worker:4.0.0
7. Accessing management console per each profile.
  • For Dashboard,
    • Business Rules:
      https://<DOCKER_HOST>:9643/business-rules
    • Portal:
      https://<DOCKER_HOST>:9643/portal
    • Monitoring:
      https://<DOCKER_HOST>:9643/monitoring
  • For Editor,
    • http://<DOCKER_HOST>:9390/editor

In here, <DOCKER_HOST> refers to hostname or IP of the host machine on top of which containers are spawned.

How to build the Kafka docker image

In order to run a distributed Stream Processor setup, Kafka is required. This section provide the steps to build the Kafka docker image.

1. Copy the extract JDK and Kafka distributions to <DOCKERFILE_HOME>/kafka/files.
  • Download JDK 1.8 and extract it to <DOCKERFILE_HOME>/kafka/files.
  • Download Kafka 2.11-0.10.0.0 and extract it to <DOCKERFILE_HOME>/kafka/files.
2. Build the base Docker image.
  • Navigate to <DOCKERFILE_HOME>/kafka directory. Execute docker build command as shown below.
    • docker build -t kafka:2.11-0.10.0.0 .
