I saw that there is no ik word segmentation plug-in in the Dockerfile in the elasticsearch.

FROM  docker.elastic.co/elasticsearch/elasticsearch:5.4.1
 
 EXPOSE 9200 9300

Excuse me, how does this install ik Chinese Word Segmentation Plug-in?

Elasticsearch installs ik plug-ins, right

FROM  docker.elastic.co/elasticsearch/elasticsearch:5.4.1
 # Add your elasticsearch plugins setup here
 # Example: RUN elasticsearch-plugin install analysis-icu
 
 RUN sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list
 RUN apt-get update && apt-get install zip
 RUN mkdir -p /usr/share/elasticsearch/plugins/ik
 RUN cd /usr/share/elasticsearch/plugins/ik && wget https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v5.6.3/  elasticsearch-analysis-ik-5.6.3.zip && unzip elasticsearch-analysis-ik-5.6.3.zip
