Docker tries to mkdir the folder that I mount

Why is Docker trying to create the folder that I'm mounting? If I cd to C:\Users\szx\Projects

docker run --rm -it -v "${PWD}:/src" ubuntu /bin/bash

This command exits with the following error:

C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: error while creating mount source path '/c/Users/szx/Projects': mkdir /c/Users/szx/Projects: file exists.

I'm using Docker Toolbox on Windows 10 Home.

Does Docker mount create directory?

It is always created as a directory. If you use --mount to bind-mount a file or directory that does not yet exist on the Docker host, Docker does not automatically create it for you, but generates an error.

How do Docker bind mounts work?

Bind mounts will mount a file or directory on to your container from your host machine, which you can then reference via its absolute path. To use bind mounts, the file or directory does not need to exist on your Docker host already. If it doesn't exist, it will be created on demand.

For anyone running mac/osx and encountering this, I restarted docker desktop in order to resolve this issue.

Edit: It would appear this also fixes the issue on Windows 10

I got this error after changing my Windows password. I had to go into Docker settings and do "Reset credentials" under "Shared Drives", then restart Docker.
