docker容器挂载宿主主机目录的操作方法

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

按照说明，如果在宿主主机的目录中再放一个war包，容器也应该自动部署，下面验证下

为了方便，我直接复制了demo.war

证明我们的猜想和实际情况是一致的

这样，我们就可以在宿主主机下根据不同的容器建立对应的便于记忆的目录路径，有发布需求的时候，直接将war包拷贝到宿主主机目录即可，容器叫什么名字，对应的容器的发布路径在哪里就与发布

总结

以上所述是小编给大家介绍的docker容器挂载宿主主机目录的操作方法，希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对我们网站的支持！
