Kafdrop is a UI for monitoring Apache Kafka clusters. The tool displays information such as brokers, topics, partitions, and even lets you view messages. It is a light weight application that runs on Spring Boot and requires very little configuration.

• Java 8
• Kafka (0.8.1 or 0.8.2 is known to work)
• Zookeeper (3.4.5 or later)

After cloning the repository, building should just be a matter of running a standard Maven build:

$ mvn clean package

The build process creates an executable JAR file.

java -jar ./target/kafdrop-<version>.jar --zookeeper.connect=<host>:<port>,<host>:<port>,...

Then open a browser and navigate to http://localhost:9000. The port can be overridden by adding the following config:

    --server.port=<port>

The following maven command will generate a Docker image:

    mvn clean package assembly:single docker:build

Note for Mac Users: You need to convert newline formatting of the kafdrop.sh file before running this command:

    dos2unix src/main/docker/*

Once the build finishes you can launch the image as follows:

    docker run -d -p 9000:9000 -e ZOOKEEPER_CONNECT=<host:port,host:port> kafdrop

And access the UI at http://localhost:9000.
