docker 安装tomcat

# 官方用法
docker run -it --rm tomcat:9.0
# docker run -it --rm 一般用来测试，用完就删除

#下载tomcat再启动
docker pull tomcat

# 启动运行tomcat
docker run -d -p 3355:8080 --name tomcat01 tomcat

# 进入容器
docker exec -it tomcat01 /bin/bash

# 进入webapps发现问题：1、Linux命令少了，2、webapps缺失内容，阿里云镜像原因，默认是最小镜像，所有不必要的都删除
# 保证最小可运行的环境

# 将webapps.dist内容拷贝到webapps目录下
cp -r  webapps.dist/* webapps

#重新刷新页面，正常进入tomcat页面。

部署es

# es 暴露的端口很多
# es十分的耗内存
# es 的数据一般需要放置到安全目录|挂载
# --net somenetwork ? 网络配置

#启动elasticsearch
docker run -d --name elasticsearch --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.6.2

# docker stats 查看cpu状态

#增加内存限制，修改配置文件 -e 环境配置修改
docker run -d --name elasticsearch02 --net somenetwork -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:7.6.2
