Docker-credential-desktop.exe executable file not found in $PATH using wsl2

Using the latest build of Windows 10 and Docker for Windows 19.03.13, I cannot specify image versions in my images using WSL2 and Ubuntu 18.

If I have the line
FROM centos:7
in my Dockerfile, I get and error message saying

failed to solve with frontend dockerfile.v0: failed to build LLB: failed to load cache key: rpc error: code = Unknown desc = error getting credentials - err: exec: “docker-credential-desktop.exe”: executable file not found in $PATH, out: ``

The problem seems to go away if I replace the 7 tag with “latest”. The problem does not occur at all if I use Powershell.

The exe is definitely in my PATH, and I can invoke it using

docker-credential-desktop.exe version

I found some discussion on the GitHub Docker for Windows page, but none of the suggestions (e.g. creating a symlink to the exe) work. People on other pages also suggested deleting the config.json file or renaming the credStore property to _credStore. These didn’t work because either the file gets recreated or the property gets changed back.

I get the same problem if I try to log into the Docker repository.

I’d be grateful for any help.

Just ran into this. You’re probably running a docker command with sudo?

Try this: sudo -E PATH="$PATH"

By default sudo doesn’t inherit environment variables, and in particular it sets PATH to secure_path from /etc/sudoers. The -E flag tells sudo to inherit environment variables (excluding PATH) which is why we need the PATH="$PATH" too.

Hope this helps.

Thank for that. I was using sudo, which was due to a problem I encountered after I upgraded to WSL2 - I had to run all docker commands with sudo. Eventually I just deleted by WSL image and downloaded a new Ubuntu image. Also, I didn’t realise you don’t need to install the Linux client tools with WSL2. Keeping them installed when I upgraded might have caused the sudo problem.

I got hit by the same, but I am not using sudo anymore.


In ~/.docker/config.json change credsStore to credStore


I was not using sudo. This worked for me, thanks!
