  2. !Encountered Errors

kafka producer: disconnected

설명:

  1. bitnami의 kafka 프로젝트 설치 후, producer의 동작을 확인하는 과정에서 에러 발생.

  2. WARN [Producer clientId=console-producer] Bootstrap broker kafka-controller-2.kafka-controller-headless.kafka.svc.cluster.local:9092 (id: -3 rack: null) disconnected (org.apache.kafka.clients.NetworkClient)

원인:

  • bitnami/kafka 프로젝트 내에서 발생하는 이슈로 파악된다.

  • https://github.com/bitnami/charts/issues/18659
  • https://github.com/bitnami/charts/issues/18793

  • SASL 과 SCRAM-SHA256이 정상적으로 이용되지 않아서 발생한 에러.

해결:

  1. 기본 SASL 프로토콜을 SASL_PLAINTEXT에서 PLAINTEXT로 바꿔서 적용한 후 설치.

  2. # 헬름 차트로 카프카 설치
    helm install kafka --set volumePermissions.enabled=true,replicaCount=3,listeners.client.protocol=PLAINTEXT oci://registry-1.docker.io/bitnamicharts/kafka

    (client.properties를 이용하지 않는다.)
