然后要给脚本赋予权限
chmod +x dynamic_mount_docker_volume
docker run --rm -v /usr/local/bin:/target jpetazzo/nsenter
注：如果不能下载，参考：https://github.com/jpetazzo/nsenter ，nsenter是一个允许根据容器名称进入容器的小工具。

进入到容器中去查看
[root@iZ1la3d1xbmukrZ docker]# docker exec -it d0fe6f850e15 /bin/bash [nexus@d0fe6f850e15 nexus]$ cd src bash: cd: src: No such file or directory [nexus@d0fe6f850e15 nexus]$ cd /src [nexus@d0fe6f850e15 src]$ ls -l total 0
进行测试，在宿主机中创建文件
[root@iZ1la3d1xbmukrZ ~]# cd /tmp/test [root@iZ1la3d1xbmukrZ test]# ll total 0 [root@iZ1la3d1xbmukrZ test]# touch 111.txt [root@iZ1la3d1xbmukrZ test]#
在容器中查看
[nexus@d0fe6f850e15 src]$ ls -l total 0 -rw-r--r-- 1 root root 0 Mar 3 12:11 111.txt [nexus@d0fe6f850e15 src]$
