How to mount a volume from Kubernetes on a Windows host to a Linux pod
To mount a volume from a Windows host to a Linux pod in Kubernetes, you can use the hostPath
volume type along with the nfs
driver. Here's an example configuration:
Create a directory on the Windows host that you want to share with the Linux pod. For example,
C:\mysharedfolder
.Set up an NFS server on the Windows host to export the directory. You can use third-party NFS server software for Windows, such as "WinNFSd" or "HaneWin NFS Server."
Configure the NFS server to export the directory (
C:\mysharedfolder
) with appropriate permissions and access settings.Install the
nfs-common
package on the Linux pod. You can include this in your pod's container by updating your Docker image or using a package manager within the container, depending on the Linux distribution you are using.Create a Kubernetes Persistent Volume (PV) and Persistent Volume Claim (PVC) manifest file, e.g.,
my-pv-pvc.yaml
. Here's an example:yamlapiVersion: v1
kind: PersistentVolume
metadata:
name: my-pv
spec:
capacity:
storage: 1Gi
accessModes:
- ReadWriteMany
persistentVolumeReclaimPolicy: Retain
storageClassName: ""
nfs:
server: <windows_host_ip> # Replace with the IP address of the Windows host
path: /mysharedfolder # Replace with the shared folder path on the Windows host
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: my-pvc
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 1Gi
Update
<windows_host_ip>
with the IP address of your Windows host.Apply the PV and PVC manifest using the following command:
perlkubectl apply -f my-pv-pvc.yaml
In your pod's manifest file, reference the PVC in the
volumes
section and mount it in thevolumeMounts
section. Here's an example:yamlapiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
containers:
- name: my-container
image: my-image
volumeMounts:
- name: my-volume
mountPath: /mnt/mysharedfolder
volumes:
- name: my-volume
persistentVolumeClaim:
claimName: my-pvc
Update the
image
and other fields according to your requirements.Apply the pod manifest using the following command:
perlkubectl apply -f my-pod.yaml
Once the pod is running, the Windows host directory (C:\mysharedfolder
) will be mounted at the specified mount path (/mnt/mysharedfolder
) within the Linux pod. Any changes made to the shared folder on the Windows host will be visible inside the Linux pod.
Please note that the setup described above involves using a Windows NFS server to share the directory. Alternatively, you could explore other solutions like using SMB/CIFS or an external storage provider compatible with both Windows and Linux.
