在容器内拷贝
cp /mnt/sourcefile /path/to/destfile
2.直接在主机上拷贝到容器物理存储系统
A. 获取容器名称或者id :
[plain] view plaincopy
$ docker ps
B. 获取整个容器的id
[plain] view plaincopy
$ docker inspect -f '{{.Id}}' 步骤A获取的名称或者id
C. 在主机上拷贝文件：
[plain] view plaincopy
$ sudo cp path-file-host /var/lib/docker/aufs/mnt/FULL_CONTAINER_ID/PATH-NEW-FILE
或者
$ sudo cp path-file-host /var/lib/docker/devicemapper/mnt/123abc《id》/rootfs/root
