helm手动部署Kafka集群

1、到指定node节点创建pv需挂载的目录，若有分布式存储可忽略

mkdir -p /data/kafka-data-0 
mkdir -p /data/kafka-data-1 
mkdir -p /data/kafka-data-2 
mkdir -p /data/kafka-zookeeper-data-0

2、创建pvc

kubectl apply -f kafka-pvc.yaml -n default

注意：kafka-22716 为后面helm安装的名字，若helm安装时名字修改需要同步修改

3、执行helm安装

helm -n default install kafka-22716 bitnami/kafka --set externalAccess.enabled=true,externalAccess.service.type=NodePort,externalAccess.autoDiscovery.enabled=true,serviceAccount.create=true,rbac.create=true,replicaCount=3,auth.clientProtocol=sasl,auth.sasl.jaas.clientUsers=user,auth.sasl.jaas.clientPasswords=user@123,auth.sasl.interBrokerMechanism=PLAIN,auth.sasl.mechanisms="PLAIN\,SCRAM-SHA-256\,SCRAM-SHA-512",image.registry=harbor.test.com,image.repository=cmq/kafka,image.tag=2.4.1-debian-10-r43,zookeeper.image.registry=harbor.test.com,zookeeper.image.repository=cmq/zookeeper,zookeeper.image.tag=3.7.0-debian-10-r106,externalAccess.autoDiscovery.image.registry=harbor.test.com,externalAccess.autoDiscovery.image.repository=cmq/kubesphere-kubectl,externalAccess.autoDiscovery.image.tag=v1.91.1,nodeSelector="kubernetes.io/hostname: node-205"

4、获取kafak的nodeport
