構建帶ik分詞器Elasticsearch7.4.2 docker鏡像

創建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'

在Dockerfile文件的同級目錄下，執行構建鏡像命令：

docker build -t es_ik:7.4.2 .

啓動容器：

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

驗證分詞起效果：

goby@/data/es-node2$ curl -XPOST  "http://127.0.0.1:9200/_analyze?pretty"  -H 'Content-Type: application/json' -d '{"text":"Kobe是一個偉大的籃球運動員","tokenizer":"ik_smart"}'
