配置nginx
需要先pull下来
#启动nginx
-d 表示后台运行
-p 表示暴露端口，将80暴露为3344
[root@iZf8zhsqf64x47n1tpdy6oZ home]# docker run -d -p:3344:80 nginx

#本机自测

配置tomcat
#当直接运行时不存在就会去下载
docker run -it --rm tomcat:9.0
--rm表示运行完成后就会自己删除，我们之前的都是不会自动删除的
遇到的问题：当我们运行了tomcat之后，是无法访问tomcat的首页的，这是因为镜像使得tomcat变成精简版本，只要能运行的版本就行，所以，如果想访问的话，就需要进行相关操作
#进入tomcat
[root@iZf8zhsqf64x47n1tpdy6oZ home]# docker exec -it 9f62708dfca5 /bin/bash
root@9f62708dfca5:/usr/local/tomcat# ls

问题解决！！
配置elasticsearch
elasticsearch是什么耗内存的，因此需要修改配置，限制内存
#限制最大内存为512m，最小内存为64m
[root@iZf8zhsqf64x47n1tpdy6oZ home]# docker run -d -p 9200:9200 -e 9300:9300 -e "discovery.type=single-node" -e ES_JAVA_OPTS="-Xms64m -Xmx512m" elasticsearch:7.6.2
可视化
docker run -d -p 8088:9000 \
--restart=always -v /var/run/docker.sock:/var/run/docker.sock --privileged=true portainer/portainer
