finding folders in the docker container

I used the following command to run the image I made in docker:

sudo docker run -it -v "${pwd}:/qc/output" qc

in fact this command should make this directory in the docker container:

/qc/output

to find this directory in the docker container I used the following commands to go to the container:

docker commit cefb2f1302cc mysnapshot
docker run -t -i mysnapshot /bin/bash

and now I am in the container as root but I did not find the “/qc/output”.
do you know how I can find this folder?
