Root Cause

Docker cannot mount the requested host path. The path may not be shared in Docker Desktop settings, or permissions are insufficient.

generic

Workarounds

  1. 92% success On macOS/Windows, add the host path to Docker Desktop file sharing settings 
    Docker Desktop > Settings > Resources > File Sharing.
Add the parent directory (e.g., /Users/yourname/projects) to the list.
Click 'Apply & Restart'.

On macOS with VirtioFS (default on newer versions), most paths under /Users are shared automatically. If using gRPC FUSE, you must explicitly add paths.

  2. 88% success Use a Docker volume instead of bind mount for better portability 
    # Create a named volume:
docker volume create mydata

# Use it instead of a bind mount:
docker run -v mydata:/app/data myimage

# In docker-compose.yml:
volumes:
  mydata:
services:
  app:
    volumes:
      - mydata:/app/data

Dead Ends

Common approaches that don't work:

  1. Running Docker as root to bypass mount permissions 70% fail

    Security risk and doesn't fix the underlying sharing/path issue on Docker Desktop
