2，docker与宿主机交互
安装es docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 --name ten_es 5acf0e8da90b 进入容器 docker exec -it ten_es /bin/bash 退出 exit #将容器的文件映射到宿主机上 docker cp ten_es:/usr/share/elasticsearch/config/elasticsearch.yml /usr/share/elasticsearch.yml #文件映射 docker cp ik ten_es:/usr/share/elasticsearch/plugins
