Unable to mount files in Docker
问题 Error description I'm unable to mount files in Vagrant or Docker, so it seems like it's an issue caused by some kind of a permission error. My OS is Ubuntu 18.04 LTS (Bionic Beaver) , I'm not running any access control modules like SELinux as far as I'm aware. The Vagrant-related discussion of the error is found in another question: Unable to mount files in Vagrant Troubleshooting Docker I'm unable to mount files into a Docker container with docker-compose, I'm trying to build: https://github
