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

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

重新访问tomcat

刷新页面,无需重启容器
