# 发现问题:
#1.linux命令变少了.
#2.没有webapp内容
#原因:阿里云镜像的原因,默认是最小的镜像,所有不必要的都剔除掉

部署es+kibana

#es 暴露端口很多
#es 十分耗内存
#es 的数据一般需要防止到安全目录,!挂载
#--net somenetwork ? 网络配置
#启动 elasticsearch
docker run -d --name elasticsearch  -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:8.1.3
#启动linux 就卡住了  
#docker stats 容器id 查看cpu的状态
# es十分耗内存
#增加内存限制 修改配置文件  -e环境配置修改
docker run -d --name elasticsearch  -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:8.1.3
