Helm 기반 Kafka 설치 + NodePort 설정

간단한 테스트들을 위해 NodePort로 설정하여 Kafka를 설치해보았다.

참고: https://github.com/bitnami/charts/tree/master/bitnami/kafka

 

1. helm repo 추가

$ helm repo add bitnami https://charts.bitnami.com/bitnami

2. volume 셋팅

  a) 디렉터리 생성

$ mkdir zoo && chmod 747 zoo
$ mkdir data && chmod 747 data

  b) volume yaml파일 작성

apiVersion: v1
kind: PersistentVolume
metadata:
  name: kafka-data
  labels:
    app: kafka-data
spec:
  storageClassName: kafka-data
  accessModes:
  - ReadWriteOnce
  hostPath:
    path: "/home/sunju/kafka/data"
  capacity:
    storage: 1Gi
 
 
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: kafka-zoo
  labels:
    app: kafka-zoo
spec:
  storageClassName: kafka-zoo
  accessModes:
  - ReadWriteOnce
  hostPath:
    path: "/home/sunju/kafka/zoo"
  capacity:
    storage: 2Gi

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: kafka-data-pvc
spec:
  storageClassName: kafka-data
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
 
 
---
 
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: kafka-zoo-pvc
spec:
  storageClassName: kafka-zoo
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 2Gi

3. helm values.yaml 파일 작성

persistence:
  enabled: true
  existingClaim: "kafka-data-pvc"
 
zookeeper:
  persistence:
    existingClaim: "kafka-zoo-pvc"
    
    
externalAccess:
  enabled: true
  service:
    type: NodePort
    nodePorts:
      - 30001
    useHostIPs: true
    domain: "192.168.1.1"

 

4. helm install

$ helm install kafka-demo -f values.yaml bitnami/kafka

NAME: kafka-demo
LAST DEPLOYED: Thu May 12 12:57:09 2022
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
** Please be patient while the chart is being deployed **

Kafka can be accessed by consumers via port 9092 on the following DNS name from within your cluster:

    kafka-demo.default.svc.cluster.local

Each Kafka broker can be accessed by producers via port 9092 on the following DNS name(s) from within your cluster:

    kafka-demo-0.kafka-demo-headless.default.svc.cluster.local:9092

To create a pod that you can use as a Kafka client run the following commands:

    kubectl run kafka-demo-client --restart='Never' --image docker.io/bitnami/kafka:2.7.0-debian-10-r29 --namespace default --command -- sleep infinity
    kubectl exec --tty -i kafka-demo-client --namespace default -- bash

    PRODUCER:
        kafka-console-producer.sh \

            --broker-list kafka-demo-0.kafka-demo-headless.default.svc.cluster.local:9092 \
            --topic test

    CONSUMER:
        kafka-console-consumer.sh \

            --bootstrap-server kafka-demo.default.svc.cluster.local:9092 \
            --topic test \
            --from-beginning

5. 결과 확인

$  kubectl get po
NAME                     READY   STATUS    RESTARTS   AGE
kafka-demo-0             1/1     Running   1          12m
kafka-demo-zookeeper-0   1/1     Running   0          12m
