helm pull bitnami/kafka
helm pull bitnami/zookeeper

[root@cce-master1 soft]# helm install -n zookeeper zookeeper bitnami/zookeeper --set persistence.storageClass=copaddon-zk-kafka,persistence.size=1Gi,replicaCount=3

helm install -f zookeeper/values.yaml --name zookeeper-cluster bitnami/zookeeper --namespace zookeeper

LAST DEPLOYED: Wed Jan 12 16:50:23 2022
NAMESPACE: zookeeper

** Please be patient while the chart is being deployed **

ZooKeeper can be accessed via port 2181 on the following DNS name from within your cluster:

    zookeeper.zookeeper.svc.cluster.local

To connect to your ZooKeeper server run the following commands:

    export POD_NAME=$(kubectl get pods --namespace zookeeper -l "app.kubernetes.io/name=zookeeper,app.kubernetes.io/instance=zookeeper,app.kubernetes.io/component=zookeeper" -o jsonpath="{.items[0].metadata.name}")
    kubectl exec -it $POD_NAME -- zkCli.sh

To connect to your ZooKeeper server from outside the cluster execute the following commands:

    kubectl port-forward --namespace zookeeper svc/zookeeper 2181:2181 &
    zkCli.sh 127.0.0.1:2181
    
    
或者是修该values.yaml文件，修改相应参数
persistence.storageClass=copaddon-zk-kafka
persistence.size=1Gi,replicaCount=3
global.imagePullSecrets= ["default-secret"]
image仓库
helm install -f zookeeper/values.yaml --name zookeeper-cluster bitnami/zookeeper --namespace zookeeper

[root@cce-master3 ~]# kubectl get pod -n zookeeper
NAME          READY   STATUS    RESTARTS   AGE
zookeeper-0   1/1     Running   0          51s

zookeeper-2   1/1     Running   0          49s

卸载
helm uninstall -n zookeeper zookeeper

zookeeper.zookeeper.svc.cluster.local

helm install -n kafka kafka bitnami/kafka --set zookeeper.enabled=false --set replicaCount=3 --set externalZookeeper.servers=zookeeper.zookeeper.svc.cluster.local --set persistence.storageClass=copaddon-zk-kafka

helm install -f kafka/values.yaml --name kafka-cluster bitnami/kafka --namespace kafka
[root@cce-master1 soft]# helm install -n kafka kafka bitnami/kafka --set zookeeper.enabled=false --set replicaCount=3 --set externalZookeeper.servers=zookeeper.zookeeper.svc.cluster.local --set persistence.storageClass=copaddon-zk-kafka
NAME: kafka
LAST DEPLOYED: Wed Jan 12 17:33:16 2022
NAMESPACE: kafka

** 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.kafka.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-0.kafka-headless.kafka.svc.cluster.local:9092
    kafka-1.kafka-headless.kafka.svc.cluster.local:9092
    kafka-2.kafka-headless.kafka.svc.cluster.local:9092

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

    kubectl run kafka-client --restart='Never' --image docker.io/bitnami/kafka:2.8.1-debian-10-r73 --namespace kafka --command -- sleep infinity
    kubectl exec --tty -i kafka-client --namespace kafka -- bash

    PRODUCER:
        kafka-console-producer.sh 

            --broker-list kafka-0.kafka-headless.kafka.svc.cluster.local:9092,kafka-1.kafka-headless.kafka.svc.cluster.local:9092,kafka-2.kafka-headless.kafka.svc.cluster.local:9092 
            --topic test

    CONSUMER:
        kafka-console-consumer.sh 

            --bootstrap-server kafka.kafka.svc.cluster.local:9092 
            --topic test 
            --from-beginning
            
            
或者修改values.yaml文件，修改成桉树
replicaCount=3
externalZookeeper.servers=zookeeper.zookeeper.svc.cluster.local
persistence.storageClass=copaddon-zk-kafka
global.imagePullSecrets= ["default-secret"]
image修改
helm install -f kafka/values.yaml --name kafka-cluster bitnami/kafka --namespace kafka

kubectl get pods --namespace zookeeper -l "app.kubernetes.io/name=zookeeper,app.kubernetes.io/instance=zookeeper,app.kubernetes.io/component=zookeeper" -o jsonpath="{.items[0].metadata.name}"

export POD_NAME=$(kubectl get pods --namespace zookeeper -l "app.kubernetes.io/name=zookeeper,app.kubernetes.io/instance=zookeeper,app.kubernetes.io/component=zookeeper" -o jsonpath="{.items[0].metadata.name}")

kubectl exec -it $POD_NAME -n zookeeper -- zkCli.sh #可以查看zk中相关的目录

kubectl run kafka-client --restart='Never' --image docker.io/bitnami/kafka:2.8.1-debian-10-r73 --namespace kafka --command -- sleep infinity
kubectl get pod -n kafka
kubectl exec --tty -i kafka-client --namespace kafka -- bash

PRODUCER:
kafka-console-producer.sh --broker-list kafka-0.kafka-headless.kafka.svc.cluster.local:9092,kafka-1.kafka-headless.kafka.svc.cluster.local:9092,kafka-2.kafka-headless.kafka.svc.cluster.local:9092 --topic test

ConSUMER
