通过Docker部署Elasticsearch

创建一个网络

es-network：定义一个网络名称

docker network create es-network

部署Elasticsearch

  • 本案例以7.12.1版本部署为例
docker pull elasticsearch:7.12.1

创建用于映射数据卷的目录

mkdir -p /root/es/es-data
mkdir -p /root/es/es-plugins

-e "ES_JAVA_OPTS=-Xms512m -Xmx512m"：指定JVM的内存，默认为1T
-e "discovery.type=single-node"：指定启动的模式为单点模式
-v es-data:：指定数据保存目录
-v es-plugins:：指定插件目录
--network es-network：指定网络
-p 9200:9200：指定HTTP协议接口的端口映射
-p 9300:9300：指定各个节点之间通讯的端口映射

docker run \
  --name es \
  -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \
  -e "discovery.type=single-node" \
  -v es-data:/root/es/es-data \
  -v es-plugins:/root/es/es-plugins \
  --privileged \
  --network es-network \
  -p 9200:9200 \
  -p 9300:9300 \
  -d \
elasticsearch:7.12.1

部署Kibana

  • Kibana需要与Elasticsearch在同一个网络
  • 本案例以7.12.1版本部署为例
docker pull kibana:7.12.1

-e ELASTICSEARCH_HOSTS=http://es:9200：指定Elasticsearch容器的地址。如果不指定，缺省值为http://elasticsearch:9200
--network es-network：指定网络

docker run \
  --name kibana \
  -e ELASTICSEARCH_HOSTS=http://es:9200 \
  --network es-network \
  -p 5601:5601 \
  -d \
kibana:7.12.1

部署ik分词器

docker exec -it es /bin/bash
./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip
exit
docker restart es
  • 拉取Kibana镜像时报错：no matching manifest for linux/arm64/v8 in the manifest list entries
  • AppleSilicon与Intel不兼容
  • 强制拉取x86_64架构的镜像

--platform linux/x86_64：如果有多种架构的镜像版本，指定需要拉取的架构版本

docker pull --platform linux/x86_64 kibana:7.12.1
  • 运行Kibana容器后，访问管理页面不成功，前段报错：Kibana server is not ready yet，后端报错：License information could not be obtained from Elasticsearch due to Error: No Living connections erro、Unable to retrieve version information from Elasticsearch nodes.
  • Kibana配置的Elasticsearch地址不正确
  • 配置文件config/kibana.yml中配置的Elasticsearch地址缺省值为：elasticsearch.hosts: [ "http://elasticsearch:9200" ]
  • 将Elasticsearch启动时，名称改为elasticsearch
  • 修改配置文件config/kibana.yml中Elasticsearch地址的配置
  • 在运行容器时，根据当前的Elasticsearch地址，指定环境变量-e ELASTICSEARCH_HOSTS=http://es:9200
