0692aec62ba9在浏览器上用公网拜访一下，测试看看，后果也是能够拜访到的，这外面前提是你的 3344 端口号曾经开发了，只有是开发的端口号都能够进行测试。
二、Docker 装置 Tomcat
# 下载 tomcat 镜像
[root@jiangwang home]# docker pull tomcat

[root@jiangwang home]# 浏览器上查看一下：后果是 404，阐明
# 进入 tomcat 容器，发现 webapps 上面什么都没有，这个是阿里云镜像的起因，默认是最小的镜像，所有不必要的都剔除了，保障最小可运行环境
[root@jiangwang home]# docker exec -it tomcat01 /bin/bash
