启动tomcat
启动 tomcat 容器，将容器的 8080 端口与外网的 8888端口进行映射
[root@VM-0-7-centos ~]# docker run -d --name artisanTomcat -p 8888:8080 tomcat

访问tomcat
访问下试试
不应该啊，看看Tomcat下的webapps
[root@VM-0-7-centos ~]# docker exec -it artisanTomcat /bin/bash

/usr/local/tomcat/webapps
root@2a0e6e886617:/usr/local/tomcat/webapps#
查看webapps & 修复问题
进入 tomcat 容器 ，发现webapps 下面什么都没有 ， 阿里云镜像 默认是最小的镜像，所有不必要的都剔除了，保证最小可运行环境
将webapps.dist 目录下的文件拷贝到 webapps下面 ，然后刷新页面就可以看到tomcat页面了
root@2a0e6e886617:/usr/local/tomcat# cd ..
root@2a0e6e886617:/usr/local/tomcat# cp -r webapps.dist/* webapps
root@2a0e6e886617:/usr/local/tomcat# cd webapps

重新访问tomcat
刷新页面，无需重启容器
