docker和主机之间数据交换

电脑和QNAP之间的交互可以用ftp, QNAP和docker可以用 docker cp, 需要先查看docke的ID

可以先登陆QNAP, 打开App center, 打开container, 点击正在运行的docker，就可以查到ID

QNAP到docker可以用如下命令

docker cp xxxxx 6994f789d928:/root

docker到QNAP可以用如下命令

docker cp  6994f789d928:/root xxxxx

登陆 QNAP方法如下, 打开 windows的 powershell, 输入如下命令，@前是用户名，后面的主机局域网IP

ssh admin@192.168.3.151

出现如下提示，输入密码

admin@192.168.3.151's password:

出现命令选项，选Q
