say I create a volume
"docker volume create --name test_VOL_34"
and then run and mount a container to it with
docker run -it -v test_VOL_34:/my_folder ubuntu:14.04 bash
from in the container I create a file in the /my_folder directory
I save that to and image
then run a container from that image , when it runs it will mount the my_folder directory
I know I wont see the file as it was in a volume and data inside a volume is not saved to the image
but I am connecting to that volume and I can see the data outside the volume
what is a good way to describe this behavior ?
“I see this comment If you mean that you’re mounting a volume over an existing directory, and expecting to see the files from the existing directory… you wont.”
I am trying to expain this to people here and having some trouble , can you confirm that this is expected behavior and if you want to add comments or reword the explanation
I just want to be clear on this before I open my mouth and attempt to expain this here
