추가로 해당강의에서 사용하는 명령어 공유드립니다!

토픽생성은 kafka control-center 에서 제공하는 페이지에서 생성하였습니다!

(localhost:9021) -> topics -> add topic

 

topic 리스트

docker exec  broker kafka-topics --bootstrap-server localhost:9092 --list

topic 정보확인

docker exec  broker kafka-topics --describe --topic quickstart-events --bootstrap-server localhost:9092

 

 

 

producer 로 메세지 생산

docker exec  broker kafka-console-producer  --broker-list localhost:9092 --topic quickstart-events

 

consumer 로 메세지 소비(수신)

docker exec  broker kafka-console-consumer --bootstrap-server localhost:9092 --topic quickstart-events --from-beginning
