Usage

To run single node kafka,

    --publish 9092:9092 \
    --publish 2181:2181 \
    --env ADVERTISED_HOST=192.168.59.103 \
    --env ADVERTISED_PORT=9092 \
    tcnksm/single-kafka

To connect it from outside of docker container, you need to expose 2 ports and set 2 env variables. 9092 for broker and 2181 for zookeeper. ADVERTISED_HOST is host IP where kafka works (in this case it is docker host) and ADVERTISED_PORT is broker port.

Testing

To try kafka you can use kafkacat,

$ echo 'This is test message' | kafkacat -t test-topic -b 192.168.59.103:9092

$ kafkacat -C -t test-topic -b 192.168.59.103:9092
