Docker volume bind is not working with current directory-CodePudding

I am Docker 20.10.17, build 100c701. Whenever I bind a local directory to a volume it doesn't show the volume using ls.

(base) hell@Dell-Precision-T7910:~/Desktop/PhD/PHD/Nvidia Modulus/Modulus v22.03$ pwd
/home/hell/Desktop/PhD/PHD/Nvidia Modulus/Modulus v22.03
(base) hell@Dell-Precision-T7910:~/Desktop/PhD/PHD/Nvidia Modulus/Modulus v22.03$ ls
'Key features.txt'   Modulus_examples   Modulus_examples.tar.gz   modulus_image_v22.03.tar.gz   Modulus_source   Modulus_source.tar.gz
(base) hell@Dell-Precision-T7910:~/Desktop/PhD/PHD/Nvidia Modulus/Modulus v22.03$ docker run --gpus all --ipc=host --ulimit memlock=-1 --ulimit stack=67108864 -v ${pwd}:/examples -it modulus:22.03 bash

root@b880211ba2ca:/examples# ls -a
.  ..
root@b880211ba2ca:/examples# ls

My pwd contains spaces and uppercase, I don't think there should a problem with spaces.

However, when I bind /home/ it works fine.

Please help me. BTW I am using Ubuntu 20.04 with RTX A5000 24GB.

CodePudding user response：

When your command uses -v ${pwd}:/examples, the syntax ${pwd} expands to an environment variable named pwd. This probably expands to an empty string; you either need the environment variable PWD (all uppercase, the case matters) or the output of the shell command pwd. You say the path includes spaces; this makes it important to put the argument in double-quotes as well.

# using the $PWD environment variable
docker run -v "${PWD}:/example" ...

# using the `pwd` command
docker run -v "$(pwd):/example" ...
