8. Docker compose를 이용하여 Kafka Confluent 설치

Docker compose를 이용하여 Kafka Confluent 설치

1. Docker Engine 설치 (URL : https://docs.docker.com/install/)

2. Docker compose 설치 (URL : https://docs.docker.com/compose/install/)

3. full-stack.yml 작성

개발기에서 운영하므로 Kafka Broker는 Single Broker로 설정한다.
그리고 Kafka를 관리하기 위해 kafka-manager를 추가하였다.

4. Docker Compose를 이용하여 full-stack.yml 실행

아래 명령어를 이용하여 도커를 실행한다.

$ docker-compose -f full-stack.yml up
## background logs
$ docker-compose -f full-stack.yml up -d

실행 후 kafka 관리 페이지에 접속 할 수 있다.
