使用docker启动elasticsearch

dockerHub官网查看elasticsearch
默认启动命令：

docker run -d --name elasticsearch --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:tag

自定义版本和内存启动：

docker run -d --name elasticsearch01 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:7.6.2

结果：

[root@dingqisui ~]# docker ps
