## 一、概述 ##

> Elasticsearch是一个基于Lucene的搜索引擎。它提供了具有HTTP Web界面和无架构JSON文档的分布式，多租户能力的全文搜索引擎。Elasticsearch是用Java开发的，根据Apache许可条款作为开源发布。

官方文档：https://www.elastic.co/guide/en/elasticsearch/reference/master/getting-started.html  
GitHub: https://github.com/elastic/elasticsearch

也可以参考我这篇文章：[分布式实时搜索和分析引擎——Elasticsearch][Elasticsearch]

## 二、Elasticsearch 编排部署 ##

地址：https://artifacthub.io/packages/helm/elastic/elasticsearch

## 1）添加源并下载编排部署包 ##

helm repo add elastic https://helm.elastic.co
    helm pull elastic/elasticsearch --version 7.17.3
    tar -xf elasticsearch-7.17.3.tgz

## 2）构建镜像 ##

Elasticsearch 各版本下载地址：https://www.elastic.co/cn/downloads/past-releases\#elasticsearch  
这里就不重新构建镜像了，有不知道怎么构建镜像的小伙伴可以给我留言或私信，这里是将远程的镜像推送到我们本地harbor，加速拉取镜像。

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
    
    # 上传镜像
    docker push myharbor.com/bigdata/elasticsearch:7.17.3
    
    # 删除镜像
    docker rmi myharbor.com/bigdata/elasticsearch:7.17.3
    crictl rmi myharbor.com/bigdata/elasticsearch:7.17.3

## 3）修改yaml编排 ##

*  elasticsearch/values.yaml

image: "myharbor.com/bigdata/elasticsearch"
    
    ...
    
    ...
    ### 去掉这几行
    volumeClaimTemplate:
      accessModes: ["ReadWriteOnce"]
      resources:
        requests:
          storage: 30Gi
    ....
    
    persistence:
      enabled: true
      labels:
        # Add default labels for the volumeClaimTemplate of the StatefulSet
        enabled: false
      annotations: {}
      accessModes:
        - ReadWriteOnce
      size: 1Gi
      storageClass: "elasticsearch-local-storage"
      local:
      - name: elasticsearch-0
        host: "local-168-182-110"
        path: "/opt/bigdata/servers/elasticsearch/data/data1"
      - name: elasticsearch-1
        host: "local-168-182-111"
        path: "/opt/bigdata/servers/elasticsearch/data/data1"
      - name: elasticsearch-2
        host: "local-168-182-112"
        path: "
