Docker on Windows: CIFS v3.02 mounts failing with big file count

Oh, well I love Docker and Windows – NOT! Another issue: https://github.com/docker/for-win/issues/2285

Description

We use containers for our developer environments. The projects are built with tools shipped within the containers. While that works like a charm for OSX and Linux, we face problems with some containers on Windows which have a heavy load of source files. The project directory is mounted to the container by CIFS 3.02.

As workaround we have found out, that builds do work with CIFS 2.0, but not with 2.1 or 3.02 mounts. If the build is failing it complains about “File not found”. Yet the file is there and can be read!
