Testing the project

You can spin up a kafka cluster with the docker-compose.yaml file by running docker-compose up -d

You can then start a consumer with:

docker exec -it broker kafka-console-consumer --bootstrap-server localhost:9092 --topic new_topic --from-beginning

Or do it with a consumer group:

docker exec -it broker kafka-console-consumer --bootstrap-server localhost:9092 --topic new_topic --group new_group --from-beginning

Create a new topic in the cluster with:

docker exec broker kafka-topics --bootstrap-server localhost:9092 --topic new_topic --create --partitions 3 --replication-factor 1

Delete a topic in the cluster with:

docker exec broker kafka-topics --bootstrap-server localhost:9092 --topic new_topic --delete

And start an interactive producer with:

docker exec --interactive --tty broker \
            kafka-console-producer --bootstrap-server localhost:9092 \
            --topic new_topic
