一、概述
Elasticsearch是一個基于Lucene的搜索引擎。它提供了具有HTTP Web界面和無架構JSON文檔的分布式，多租戶能力的全文搜索引擎。Elasticsearch是用Java開發的，根據Apache許可條款作為開源發布。

二、Elasticsearch 編排部署
地址：https://artifacthub.io/packages/helm/elastic/elasticsearch
1）添加源并下載編排部署包
helm repo add elastic https://helm.elastic.co
helm pull elastic/elasticsearch --version 7.17.3
tar -xf elasticsearch-7.17.3.tgz
2）構建鏡像
Elasticsearch 各版本下載地址：https://www.elastic.co/cn/downloads/past-releases#elasticsearch這里就不重新構建鏡像了，這里是將遠程的鏡像推送到我們本地harbor，加速拉取鏡像。
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.17.3
docker tag docker.elastic.co/elasticsearch/elasticsearch:7.17.3 myharbor.com/bigdata/elasticsearch:7.17.3
# 上傳鏡像
docker push myharbor.com/bigdata/elasticsearch:7.17.3
# 刪除鏡像
docker rmi myharbor.com/bigdata/elasticsearch:7.17.3
crictl rmi myharbor.com/bigdata/elasticsearch:7.17.3
3）修改yaml編排
- elasticsearch/values.yaml
image: "myharbor.com/bigdata/elasticsearch"
...
...
### 去掉這幾行
volumeClaimTemplate:
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 30Gi
....
persistence:

4）開始部署
# 先創建本地存儲目錄
mkdir -p /opt/bigdata/servers/elasticsearch/data/data1
chmod -R 777 /opt/bigdata/servers/elasticsearch/data/data1
helm install my-elasticsearch ./elasticsearch -n elasticsearch --create-namespace
# 查看
helm get notes my-elasticsearch -n elasticsearch
kubectl get pods,svc -n elasticsearch -owide
NOTES
NAME: my-elasticsearch
LAST DEPLOYED: Wed Oct 12 23:47:17 2022
NAMESPACE: elasticsearch
STATUS: deployed
REVISION: 1
NOTES:
1. Watch all cluster members come up.
$ kubectl get pods --namespace=elasticsearch -l app=elasticsearch-master -w2. Test cluster health using Helm test.
$ helm --namespace=elasticsearch test my-elasticsearch
5）測試驗證

7）卸載
helm uninstall my-elasticsearch -n elasticsearch
kubectl delete ns elasticsearch --force
rm -fr /opt/bigdata/servers/elasticsearch/data/data1/*
ssh local-168-182-111 "rm -fr /opt/bigdata/servers/elasticsearch/data/data1/*"
ssh local-168-182-112 "rm -fr /opt/bigdata/servers/elasticsearch/data/data1/*"

ssh local-168-182-112 "crictl rmi myharbor.com/bigdata/elasticsearch:7.17.3"
三、Kibana 編排部署
地址：https://artifacthub.io/packages/helm/bitnami/kibana?modal=install
1）添加源并下載編排部署包
helm repo add bitnami https://charts.bitnami.com/bitnami
helm pull bitnami/kibana --version 10.2.6
tar -xf kibana-10.2.6.tgz
2）構建鏡像
這里也不重新構建鏡像了，只是將鏡像推送到本地harbor加速，【注意】版本號需要跟ES相對應，版本不一樣，可能會存儲不兼容的情況。
docker pull docker.io/bitnami/kibana:7.17.3
docker tag docker.io/bitnami/kibana:7.17.3 myharbor.com/bigdata/kibana:7.17.3
# 上傳鏡像
docker push myharbor.com/bigdata/kibana:7.17.3
# 刪除鏡像
docker rmi myharbor.com/bigdata/kibana:7.17.3
crictl rmi myharbor.com/bigdata/kibana:7.17.3
3）修改yaml編排
