kafdrop-docker-image

Using the baseimage maven:alpine from Docker Hub, kafdrop is compiled and included in the image.

Some environment variable can be adjusted at runtime:

ZK_HOSTS=localhost:2181
LISTEN=9000

The default command of the image is

java -jar /usr/local/bin/kafdrop.jar \
    --zookeeper.connect=${ZK_HOSTS} --server.port=${LISTEN}

If there is a working kafka instance running on localhost (aka: the zookeeper ports are accessible), start a container with

docker run -e ZK_HOSTS=localhost:2181 -e LISTEN=9010 \
    thomsch98/kafdrop:alpine

For docker-compose, assume a setup like this

kafdrop:
    image: thomsch98/kafdrop:alpine
    ports:
    - "9010:9010" 
    environment:
    - "ZK_HOSTS=kafka:2181"
    - "LISTEN=9010"
    logging:
    driver: journald

kafka:
    image: massenz/kafka:0.10.1.1
    hostname: kafka
    ports:
    - "2181:2181"
    - "9092:9092"
    environment:
    - "ADVERTISED_HOST=kafka"
    - "ADVERTISED_PORT=9092"
    logging:
    driver: journald
