一、Zookeeper集群扩容

1.修改values.yaml相应配置,搜索replicaCount，将副本数修改为5

[root@k8s-master01 ~]# cd /root/zookeeper
[root@k8s-master01 zookeeper]# vim values.yaml

2.开始扩容

[root@k8s-master01 ~]# cd /root/zookeeper
[root@k8s-master01 zookeeper]# helm upgrade -n public-service zookeeper .

3.查看pod建立情况,观察到已经成功扩容

[root@k8s-master01 zookeeper]# kubectl get po -n public-service
NAME           READY   STATUS              RESTARTS   AGE
kafka-0        1/1     Running             0          3h27m
kafka-1        1/1     Running             0          3h27m
kafka-2        1/1     Running             0          3h27m
kafka-3        1/1     Running             0          13m
kafka-4        1/1     Running             0          13m
kafka-client   1/1     Running             0          44m
zookeeper-0    1/1     Running             0          3h48m
zookeeper-1    1/1     Running             0          3h48m
zookeeper-2    1/1     Running             0          3h48m
zookeeper-3    1/1     Running             0          118s
zookeeper-4    1/1     Running             0          118s

二、删除Zookeeper集群

执行helm delete -n public-service zookeeper命令卸载zookeeper集群

$ helm delete  -n public-service zookeeper
