Did you really create a file in the Linux root? Unless you did it as a root user, you don’t even have permission to do that. If the file is not there, as the error message cleary says, it is normal to have the error message.

Nothing at all indicated in the error message that the container is not there. It is the file which is not there.

I have not used sudo but with out sudo when I created file using touch command it did not give any error .
however I tried now with sudo, even I am trying to give right password it is not allowing me to proceed further. could you please advise on this ?

shyam@DESKTOP-OO7EVK2:/$ touch shyamfile.txt
touch: cannot touch 'shyamfile.txt': Permission denied
shyam@DESKTOP-OO7EVK2:/$ sudo touch shyamfile.txt
[sudo] password for shyam:
Sorry, try again.
[sudo] password for shyam:
Sorry, try again.
[sudo] password for shyam:
sudo: 3 incorrect password attempts

Please share following outputs:

docker info
ls -l

The ls -l command must be done in the folder where you want to use docker cp.

Note: if you use docker cp for anything else than “testing something out” or copying files from the container to the host, you most likely try to do something that either should be done by binding a host folder as volume, or by creating a new image where the file is copied into the image.
