Minikube doesn't mount host's user home directory on HyperV VM (Windows 10)

[addshore]

Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG REPORT

Please provide the following details:

Environment:

Minikube version (use minikube version): minikube version: v0.24.1

• OS (e.g. from /etc/os-release): Windows 10 (Version 1709 - OS Build 16299.125)
• VM Driver (e.g. cat ~/.minikube/machines/minikube/config.json | grep DriverName): "DriverName": "hyperv",
• ISO version (e.g. cat ~/.minikube/machines/minikube/config.json | grep -i ISO or minikube ssh cat /etc/VERSION): "Boot2DockerURL": "file://C:/Users/adam/.minikube/cache/iso/minikube-v0.23.6.iso",

What happened:

I believe this could be similar to #716
My home directory is not mounted to the minikube VM.

minikube start --vm-driver=hyperv
minikube ssh

What you expected to happen:

(copied form #716) I should normally be able to access this directory through the VM. I need this to provide files to the containers controlled by Kubernetes.

--mount-string string The argument to pass the minikube mount command on start (default "C:\Users\USERNAME:/minikube-host")

How to reproduce it (as minimally and precisely as possible):

(copied form #716) Run minikube start then minikube ssh. In the shell we are unable to find the mounted host directory under any names

Anything else do we need to know:

I'm new to kubernetes on Windows so I could be screwing something up here.
But this looks so simple I surely can't be.

W/o it fixed, unfortunatelly cant use minikube under windows 10 with hyperv for local development, unless some workaround for mount?

[gbraad]

HyperV does not provide any standard hostfolder solution OOTB. You can use something like fuse-sshfs or smb maybe. We have added this to Minishift, but haven't backported any of this to minikube yet; bandwidth issues/too busy.

i understand, just wanted to confirm and bump the issue

https://kubernetes.io/docs/getting-started-guides/minikube/#mounted-host-folders
Hyper-V not supported etc. / not listed

[kochinc]

With minikube version: v0.27.0, when you run
minikube start --vm-driver=hyperv --mount
your home directory will be mounted on /minikube-host in your minikube virtual machine. Since normally there are lots of directories and files in the home directory, it would be cleaner to run the command with the directory specified, like
minikube start --vm-driver=hyperv --mount --mount-string="C:\Users\AUser\AFolder:/minikube-host"
Be aware that the host directory is mounted in the virtual machine as a Plan9 filesystem via TCP, so you need to make sure your firewall or security software is not dropping connections from minikube virtual machine.

@kochinc sorry but is this change introduced in 0.27, cant find in changelogs cause this will realy fix many setups?Thx.

[kochinc]

The options --mount and --mount-string have been in minikube for several revisions already. But I just started using minikube on Hyper-V, so have no idea whether mounting host directory on Hyper-V was working or not before. And, there are still issues with the mounted directory. It is always mounted as root:root, and modification time is wrong. For copying files into and out of the Hyper-V virtual machine is working, though.
