In 2.0, mounting folders from docker is not supported, as documented at https://circleci.com/docs/2.0/building-docker-images/#mounting-folders. What’s the reason behind that?
For context, I was trying to migrate a build of one of my repos that requires this feature. Asking docker to mount the volume was fine, but no files were visible there.
This repo of mine is a docker tool, and has some very peculiar needs. If 2.0 doesn’t not support mounting volumes, I’ll probably migrate away from CircleCI altogether.
P.S.: my repo is open source. I can share the link to my migration attempt if that helps.
