-# 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.
