    -# Gearpump Launcher Docker Image
    -
    -The image helps developer to setup/test a local [Gearpump](https://github.com/apache/incubator-gearpump.git)
cluster quickly. The image is based on a minimal JRE8 environment with Python support. 
    -
    -## Usage
    -
    -Here are the commands to launch a cluster. You can launch as many worker containers as
you wish but only one master for the time being.
    -```
    -export GEARPUMP_HOME=/path/to/gearpump
    -
    -docker run -d \
    - -h master0 --name master0 \
    - -v $GEARPUMP_HOME:/opt/gearpump \
    - -e JAVA_OPTS=-Dgearpump.cluster.masters.0=master0:3000 \
    - -p 8090:8090 \
    - stanleyxu2005/gearpump-launcher \
    - master -ip master0 -port 3000
    -
    -docker run -d \
    - --link master0 \
    - -v $GEARPUMP_HOME:/opt/gearpump \
    - -e JAVA_OPTS=-Dgearpump.cluster.masters.0=master0:3000 \
    - stanleyxu2005/gearpump-launcher \
    - worker
    -
    -docker exec master0 gear info
    -docker exec master0 gear app -jar /path/to/userapp.jar [mainclass] [args]

    +This folder contains docker images definitions used in integration tests of Gearpump.
    +
    +
    +These include:
    +
    + * [The standalone single node Kafka cluster with Zookeeper](/kafka)
    + * [The Hadoop image](/hadoop)
    + * [The Gearpump Cluster Launcher and Storm Client](/gearpump)
    + * [Java 8 JRE image](/java)
    +
    +
    +We decided to fork spotify/kafka image, because the project does not maintain proper
tagging. 
    +For now our tests focus on Kafka 0.8.x, and the project does not support this version.

    +
    +Hadoop docker image (https://hub.docker.com/r/sequenceiq/hadoop-docker/) is well maintained.

    +We rely on version 2.6.0 and we feel there is no need to duplicate it.
    +
    +Gearpump Cluster Launcher  helps developer to setup/test a local Gearpump cluster quickly.

    +The image is based on a minimal JRE8 environment with Python support.
    +
    +We used to base Gearpump Cluster Launcher on errordeveloper/oracle-jre image but it stuck
on version 8u66-b17 and doesn't support tagging.
    +We also probably hit a Java bug (http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8133205)
that requires never version of JRE.
