k8s zookeeper安装(集群版与非集群版)

集群版zookeeper安装

第一步：添加helm镜像源

helm repo add incubator http://storage.googleapis.com/kubernetes-charts-incubator

第二步：下载Zookeeper

helm fetch incubator/zookeeper

第三步：修改

...
persistence:
  enabled: true
  ## zookeeper data Persistent Volume Storage Class
  ## If defined, storageClassName: <storageClass>
  ## If set to "-", storageClassName: "", which disables dynamic provisioning
  ## If undefined (the default) or set to null, no storageClassName spec is
  ##   set, choosing the default provisioner.  (gp2 on AWS, standard on
  ##   GKE, AWS & OpenStack)
  ##
  storageClass: "nfs-client"
  accessMode: ReadWriteOnce
  size: 5Gi
...

注意：

1、如果已有存储，可不执行以下操作，将现有的storageClass替换即可

查看storageclass，替换对应的NAME

kubectl get sc -(namespace名称)

[root@k8s-master zookeeper]# kubectl get sc -n xxxxxx
NAME       PROVISION                                          RECLAIMPOLICY VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
nfs-client cluster.local/moldy-seagull-nfs-client-provisioner Delete        Immediate           true                   16d

2、如果没有存储，执行下列操作时，注意存储的方式及地址

修改存储（storageclass 名称为kubectl get sc -(namespace名称) 下面的共享存储卷，如果没有按照以下步骤安装)

1、集群版本：如果是1.19+

# xxx填写存储地址，例如nfs共享存储填写ip：192.168.8.158
helm install --set nfs.server=x.x.x.x --set nfs.path=/exported/path stable/nfs-client-provisioner

如果出现错误

Error: failed to download "stable/nfs-client-provisioner" (hint: running `helm repo update` may help)

2、如果是1.19版本以下执行yaml文件

$ kubectl create -f nfs-client-sa.yaml
$ kubectl create -f nfs-client-class.yaml
$ kubectl create -f nfs-client.yaml

注意nfs-client.yaml存储地址！！！

nfs-client-sa.yaml

非集群版zookeeper安装

注意：zookeeper.yaml中存储地址，根据实际情况修改存储（共有三处PV需要修改）

kubectl apply -f zookeeper.yaml -n xxxxx

安装nimbus-ui

kubectl create deployment stormui --image=adejonge/storm-ui -n xxxxxx

第二步：安装svc

kubectl expose deployment stormui --port=8080 --type=nodeport -n xxxxxxx

第三步：创建config map

安装zk-ui
