I have logged into the docker from the below command, now from the python script i want to copy the file from docker to host system how to do this
sudo docker run -ti video:new /bin/bash
import os
os.system('cp /tmp/a.txt HOST:/tmp/a.txt')
Map a volume to share data with your host from the container.
docker run -v /tmp/:/tmp/ -ti video:new /bin/bash
Then let your python script copy the file to the /tmp directory inside your container.
import os
os.system('cp /path/to/a.txt /tmp/a.txt')
Through to the -v mapping, the file is placed on the docker host in the directory /tmp. Once you close your docker container, the file will still exist on the host as /tmp/a.txt.
The container can't copy information outside its isolation. If you wanna share information between container and host, please use volume mapper to do that (-v):
