Expected behavior
Mount an iso9660 filesystem via loopback. Identical code works on docker-machine Virtualbox and VMware Fusion
Actual behavior
“mount: unknown filesystem type ‘iso9660’”
And:
$ docker run -ti ubuntu:xenial /bin/bash
root@5cb2d83c2104:/# egrep iso /proc/filesystems
root@5cb2d83c2104:/#
It looks very much like iso9660 is just not in the kernel.
Information
No-change invocation of a (Rancher) Dapper make fails on Docker for Mac, works fine on Docker Machine on Virtualbox or VMware, and on native (Docker Inc. repository) docker on Ubuntu Xenial x86_64.
Steps to reproduce the behavior
- Attempt to mount any iso9660 filesystem in a container on Docker for Mac
- Fail with “mount: unknown filesystem type ‘iso9660’”
