cmd

#JAVA_OPTS='-Xmx512m'
docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m" -d -p 9200:9200 -p 9300:9300 -v /Users/lzq/docker/elasticsearch/es-single.yml:/usr/share/elasticsearch/config/elasticsearch.yml -v /Users/lzq/docker/elasticsearch/esdata-single:/usr/share/elasticsearch/data --name es-single elasticsearch:7.2.0

• 设置-e ES_JAVA_OPTS="-Xms256m -Xmx256m" 是因为/etc/elasticsearch/jvm.options 默认jvm最大最小内存是2G，读者启动容器后 可用docker stats命令查看
• -p是绑定端口，请保持9200:9200前后一致
• -v是做文件映射，当前主机的文件映射到docker内部
• --name是给容器设定一个名字，名字不能重复
