1.准备文件

1.1.创建命令空间

kubectl create ns kafka

1.1.helm包拉取本地

# 添加bitnami仓库
helm repo add bitnami https://charts.bitnami.com/bitnami
# 查询chart
helm search repo bitnami
# 拉取zookeeper
helm pull bitnami/zookeeper
# 解压
tar zxvf  zookeeper-12.0.0.tgz
#进入Zookeeper
cd zookeeper
# 查看包内容
ls
Chart.lock  charts  Chart.yaml  README.md  templates  values.yaml

1.1.修改values

vim values.yaml
extraEnvVars: 
  - name: TZ
    value: "Asia/Shanghai"
# 允许任意用户连接（默认开启）,本地文件没有需要自己添加
allowAnonymousLogin: true
---
# 关闭认证（默认关闭）
auth:
  enable: false
---
# 修改副本数
replicaCount: 3
---
# 4. 配置持久化，按需使用
global:
  imageRegistry: ""
  imagePullSecrets: []
  storageClass: "nfs-storage"

1.3.创建zookeeper集群

#部署
helm install zookeeper -n kafka .
NAME: zookeeper
LAST DEPLOYED: Sat Dec 16 23:03:46 2023
NAMESPACE: zookeeper
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
CHART NAME: zookeeper
CHART VERSION: 12.0.0
APP VERSION: 3.9.0
​
** 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

1.3.1.查看资源状态

kubectl get  all -n  kafka

​
#查看挂载状态，本地使用nfs作为持久化
 kubectl get  pvc -n  kafka
