「云原生」Elasticsearch + Kibana on k8s 讲解与实战操作

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

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

annotations: {}

- ReadWriteOnce
```
