How to use host storage in kubernetes

[thexder1]

Expected behavior

Able to mount shared drive in containers running in kubernetes

Actual behavior

Could not find any way to configure this

Information

I am using Docker for Windows Edge with the built in Kubernetes configuration and trying to mount a persistent volume of some kind from the host. I am running Windows 10 Enterprise. I thought I would be able to use the local volumes that were added as alpha in Kubernetes, but they are behind feature gates and I do not see any way to enable them so I can use that.

Steps to reproduce the behavior

1. Install Docker for Windows Edge
2. Make sure you are using Linux Containers
3. Open Docker settings, go to kubernetes tab and check the boxes and click apply
4. Go to shared drives tab and share drive
5. Ponder the possible ways this share could get passed into kubernetes.

Hello,

In the 18.03-rc1 edge version (due this week), you will be able to use hostPath type volume to mount volumes shared from the host. Just use a hostPath volume. VM-side, the shared drive are in the /host_mnt folder. I.E: "/host_mnt/c/path/to/my/folder for a folder in the C drive.

That does not seem to work, gives me an error saying something about failing test for directory.

OK, it works when I do not specify a type, but if I speficy type: Directory I get the error "MountVolume.SetUp failed for volume "host" : hostPath type check failed: /host_mnt/e/mysql_data is not a directory" on anything other than the root.

Do you need to have shared drives set up to enable k8s persistent volumes? It asks me to share the c:\ drive whenever I try to create a PVC.

Seeing the same behavior as in #77 and I am not having success with setting up shared drives in Docker for Windows. Tried suggestions here: http://peterjohnlightfoot.com/docker-for-windows-on-hyper-v-fix-the-host-volume-sharing-issue/ and here: https://blogs.msdn.microsoft.com/stevelasker/2016/06/14/configuring-docker-for-windows-volumes/

Neither work.

Invalid mode issue can be solved for me by replacing

C:/WhateverPath

with

/C/WhateverPath

Misleading error message, but there's an issue for that already here:

kubernetes/kubernetes#59876

@pgayvallet Thank you for your comment, it totally works, how... do you know this? :)

I'm trying to figure out where the documentation is for this, but the only thing I can find is a reference in Docker for Windows Stable Release notes under Docker Community Edition 17.12.0-ce-win47 2018-01-12:

Fix Mount compatibility when mounting drives with -v //c/..., now mounted in /host_mnt/c in the LinuxKit VM. Fixes #1509, #1516, #1497

Thank you! (I'm only commenting here because the issue is still open.)
