docker构建带ik分词器Elasticsearch镜像

1. 创建Dockerfile 文件：

FROM elasticsearch:7.4.2
RUN cd /usr/share/elasticsearch && sh -c '/bin/echo -e "y" | elasticsearch-plugin install  https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.4.2/elasticsearch-analysis-ik-7.4.2.zip'

RUN cd /usr/share/elasticsearch && sh -c '/bin/echo -e "y" | elasticsearch-plugin install  https://github.com/medcl/elasticsearch-analysis-pinyin/releases/download/v7.4.2/elasticsearch-analysis-pinyin-7.4.2.zip'

1. 在Dockerfile文件的同级目录下，执行构建镜像命令：

docker build -t es_ik:7.4.2 .

1. 启动容器：

docker run -itd -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" --name es-ik  es_ik:7.4.2

1. 验证分词器效果：

curl -XPOST  "http://127.0.0.1:9200/_analyze?pretty"  -H 'Content-Type: application/json' -d '{"text":"希望疫情早日结束,出门不必再戴口罩","tokenizer":"ik_smart"}'

返回
