Docker unable to mount nginx - docker

Question

I'm having issues setting up Docker for the first time on a Windows using the Docker Toolbox. Everything works except nginx at the moment.
Error message:

The issue seems to be related to Nginx with the default.conf not being accessible or the app thinkgs it's a folder and not a file.
I checked the issue online and people suggests to mount the C: folder so I tried to mount it on Oracle VirtualBox and re-run the docker-compose up command but it didn't solve the issue.
Any idea?

Answer 1

I solved same problem with sharing folder with Oracle VirtualBox VM default
Share your project folder and restart your vm.
You can do even with command like
docker-machine stop default & docker-machine stop default
Now, you need to use shared name (project) instead of . in your compose file (docker-compose.yml)
For your case,
- ./nginx/default.conf:/etc/nginx/conf.d/default.conf
should changed to
- /sharename/nginx/default.conf:/etc/nginx/conf.d/default.conf
Now try with docker-compose up.
It worked for me.
