本文主要包含docker容器挂载,docker,宿主主机目录等服务器相关知识,肖哥哥 希望可以进行参考
有一项重要的参数 -v 目录挂载，就是让容器内部目录和宿主主机目录关联起来，这样就可以直接操作宿主主机目录而不用再操作具体容器了
比如在2中，我们要发布一个war包，是通过
sudo docker cp demo.war tomcat_xiao:/usr/local/tomcat/webapps
来发布的，有没有更快捷的方式呢？
肯定有， 没有 我就不会在这里写这些玩意儿了
sudo docker run -p 8822:8080 --name tomcat_xiao_volume -v /home/xiaochangwei/test:/usr/local/tomcat/webapps xiaochangwei/tomcat:v1
-p 不解释
--name 不解释
-v /home/xiaochangwei/test:/usr/local/tomcat/webapps 就是将宿主主机目录和容器目录建立映射关系，冒号前为宿主主机目录，冒号后为容器对应目录
执行上面的命令启动，这次启动就和上一篇文章中的启动日志有点差异了：差异就在容器启动时，tomcat加载了我们映射的宿主主机目录中的war包
