kubesphere 部署 zookeeper 和 kafka 以及 在k8s 部署是需要注意的问题

搭建zookeeper

选用镜像是官方镜像 zookeeper 内存和cpu 限制不用给太多

创建配置字典 和存储卷 用于持久化数据 和挂载配置文件

存储卷 自行创建

配置字典

dataDir=/data  # 保存zookeeper中的数据
clientPort=2181 # 客户端连接端口，通常不做修改
dataLogDir=/datalog
tickTime=2000  # 通信心跳时间
initLimit=5    # LF(leader - follower)初始通信时限
syncLimit=2    # LF 同步通信时限
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
standaloneEnabled=true
admin.enableServer=true
server.1=localhost:2888:3888;2181

搭建kafka

选用镜像 wurstmeister/zookeeper 启动是添加环境变量

 KAFKA_BROKER_ID：0   #该ID是集群的唯一标识

 KAFKA_ADVERTISED_LISTENERS：PLAINTEXT://local.wuanwanghao.top:9092  #kafka发布到zookeeper供客户端使用的服务地址。

 KAFKA_ZOOKEEPER_CONNECT： zookeeper.wanghao:2181 #zk的连接地址

 KAFKA_LISTENERS：PLAINTEXT://0.0.0.0:9092 #允许使用PLAINTEXT侦听器

主要一点创建kafka 相应服务的时候一定不要把服务名称定义为kafka, 相关问题以踩坑 Invalid value tcp://10.0.35.234:9092 for configuration port: Not a number of type INT
