Kubernetes on Windows Persistent Volume

Question

Does windows minikube support a persistent volume with a hostpath? If so what is the syntax?

I tried:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: kbmongo002
  labels:
    type: local
spec:
  storageClassName: mongostorageclass
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/temp/mongo"
    persistentVolumeReclaimPolicy: Retain
---

This passed validation and created the PV and a PVC claimed it, but nothing was written to my expected location of C:\temp\mongo

I also tried:

  hostPath:
    path: "c:/temp/mongo"
    persistentVolumeReclaimPolicy: Retain
---

That resulted in:

Error: Error response from daemon: Invalid bind mount spec 
"c:/temp/mongo:/data/db": invalid mode: /data/db 
Error syncing pod

how are you mounting your host folder into the VM? – aaron-prindle Jul 14 '17 at 21:48 — aaron-prindle, Jul 14 '17 at 21:48

If you use virtualbox in windows, only the c:/Users is mapped into vm as /c/Users which is kubernetes system can access. It is the feature in Virtualbox.

Minikube use VM to simulate the kubernetes VM.

Minikube provides mount feature as well, not so user-friendly for persitency.

You can try choose one of the solutions below

use folders under /c/Users for your yaml file
map extra folders into virtualbox VM like C:\Users
use minikube mount, see host folder mount

I have tried k8s hostpath on windows, it works well. You should use drive letter in pod mount path, see example: https://github.com/andyzhangx/Demo/blob/master/windows/azuredisk/aspnet-pod-azuredisk.yaml#L14

As there is a docker mount path related bug on windows, you need to use drive letter as mount path in pod, see issue: https://github.com/moby/moby/issues/34729
