es、ik分词器、kibana三个的版本得一致，否则安装之后无法正常使用

准备工作：
sudo mkdir -p /data/es_docker/{data,logs,plugins,config}
sudo chmod -R 777 /data/es_docker # 确保容器有写入权限

1、制作包含ik分词器扩展的es 镜像的Dockerfile脚本：

FROM elasticsearch:8.5.3
USER root
# 安装 IK 分词器（确保版本与 Elasticsearch 一致）
RUN elasticsearch-plugin install -b https://get.infini.cloud/elasticsearch/analysis-ik/8.5.3
USER elasticsearch

ik分词器得git网站链接：https://github.com/infinilabs/analysis-ik/

2、生成本地镜像

docker build -t elasticsearch-ik:8.5.3 .

3. docker-compose.yml

version: '3.8'

services:
  elasticsearch:
    image: elasticsearch-ik:8.5.3
    container_name: elasticsearch
    environment:
      - ES_JAVA_OPTS=-Xms1024m -Xmx1024m
      - discovery.type=single-node
      - xpack.security.enabled=false
    volumes:
      - /data/es_docker/data:/usr/share/elasticsearch/data
      - /data/es_docker/logs:/usr/share/elasticsearch/logs
    ports:
      - "9200:9200"
      - "9300:9300"
    networks:
      - es-net
    restart: always
    privileged: true
  kibana:
    image: kibana:8.5.3
    container_name: kibana
    environment:
      - ELASTICSEARCH_HOSTS=http://elasticsearch:9200
    ports:
      - "5601:5601"
    networks:
      - es-net
    restart: always
    depends_on:
      - elasticsearch

networks:
  es-net:
    driver: bridge

4、在docker-compose.yml所在的目录执行以下命令行

docker-compose down && docker-compose up -d

5、复制容器内的扩展到本地

docker cp elasticsearch:/usr/share/elasticsearch/plugins/analysis-ik /data/es_docker/plugins/
重启：
docker-compose down && docker-compose up -d
