kafcker

Collection of Docker resources for Kafka in a sandbox environment

This is based on original work done by wurstmeister Please check out the repo here: https://github.com/wurstmeister/kafka-docker

I have made some modifications to fit some of my use-cases and to make local development a little bit easier.

Getting started

Initialize the stack

To start the stack run:

# Downloads images, allocates network, and starts all containers
# in the background.
docker-compose up -d

To view logs at any time:

docker-compose logs -f

Interact with the stack

To start a shell to interact

./start-kafka-shell.sh

Once inside of the shell you can run the commands detailed here in the Testing section:

Reference: https://wurstmeister.github.io/kafka-docker/

Initialize topic

# Create a topic called "topic"
$KAFKA_HOME/bin/kafka-topics.sh --create --topic topic \
--partitions 4 --zookeeper $ZK --replication-factor 1
# Check to make sure that topic exists
$KAFKA_HOME/bin/kafka-topics.sh --describe --topic topic --zookeeper $ZK

Start producing

# Start producer
$KAFKA_HOME/bin/kafka-console-producer.sh --topic=topic \
--broker-list=`broker-list.sh`

Anything typed in the stdin will be sent as a message to the topic

Start consuming

In a separate tab/window navigate to the cloned kafcker directory and run the following commands:

# Start shell
./start-kafka-shell.sh
# Start consumer
$KAFKA_HOME/bin/kafka-console-producer.sh --topic=topic \
--broker-list=`broker-list.sh`

Any messages sent via the producer, should be seen in the consumer window/tab.
