我们使用docker ps查看端口号
访问猫首页
为什么上面的tomcat上面啥没有猫猫？
因为这是新版，我们进入tomcat看一下

这是因为真正有货的是webapps.dist，而web apps里面是空的，此时我们删除并且改名
root@9e194dbf7eca:/usr/local/tomcat/webapps# cd .. &&rm -r webapps
root@9e194dbf7eca:/usr/local/tomcat# mv webapps.dist/ webapps &&cd webapps &&ls -al

如上图，成功了（我设置了映射）
推荐使用的版本
我们的版本是最新的tomcat，其实用不到这么新的，可以删除后重新安装一个旧的
docker run -d -p 8080:8080 --name tomcat03 billygoo/tomcat8-jdk8
查看端口
root@ubuntu:/tmp/host_data# docker ps

建议初学者使用后面的方法就行
