k8s zookeeper安裝(集群版與非集群版)

集群版zookeeper安裝

第一步：添加helm鏡像源

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

第二步：下載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、如果已有存儲，可不執行以下操作，將現有的storageClass替換即可

查看storageclass，替換對應的NAME

kubectl get sc -(namespace名稱)

[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、如果沒有存儲，執行下列操作時，注意存儲的方式及地址

修改存儲（storageclass 名稱為kubectl get sc -(namespace名稱) 下面的共享存儲卷，如果沒有按照以下步驟安裝)

1、集群版本：如果是1.19+

# xxx填寫存儲地址，例如nfs共享存儲填寫ip：192.168.8.158
helm install --set nfs.server=x.x.x.x --set nfs.path=/exported/path stable/nfs-client-provisioner

如果出現錯誤

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

2、如果是1.19版本以下執行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存儲地址！！！

nfs-client-sa.yaml

非集群版zookeeper安裝

注意：zookeeper.yaml中存儲地址，根據實際情況修改存儲（共有三處PV需要修改）

kubectl apply -f zookeeper.yaml -n xxxxx

zookeeper.yaml

安裝nimbus

第一步：安裝nimbus配置文件config map

注意：nimbus-cm.yaml中的zookeeper為zookeeper的service名稱

kubectl apply -fnimbus-cm.yaml -n xxxxxx

nimbus-cm.yaml

  storm.yaml: |
    # DataSource
    storm.zookeeper.servers: [zookeeper]

安裝nimbus-ui

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

第二步：安裝svc

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

第三步：創建config map

安裝zk-ui

kubectl apply -f zookeeper-program-ui.yaml -n xxxxxxx
