I am currently trying to deploy the following on Minikube. I used the configuration files to use a hostpath as a persistent storage on minikube node.
apiVersion: v1
kind: PersistentVolume
metadata:
name: "pv-volume"
spec:
capacity:
storage: "20Gi"
accessModes:
- "ReadWriteOnce"
hostPath:
path: /data
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: "orientdb-pv-claim"
spec:
accessModes:
- "ReadWriteOnce"
resources:
requests:
storage: "20Gi"

mountPath: /data/orientdb/databases

persistentVolumeClaim:
claimName: orientdb-pv-claim

persistentVolumeClaim:
claimName: orientdb-pv-claim
- name: orientdb-backup
persistentVolumeClaim:
claimName: orientdb-pv-claim

I see the following error

Is there something incorrect in way I am creating Persistent Volume and PersistentVolumeClaim on my node.
minikube version: v0.20.0
Appreciate all the help
Your configuration is fine.
Tested under minikube v0.24.0
, minikube v0.25.0
and minikube v0.26.1
without any problem.
Take in mind that minikube is under active development, and, specially if you're under windows, is like they say experimental software.
Update to a newer version of minikube and redeploy it. This should solve the problem.
You can check for updates with the minikube update-check
command which results in something like this:
$ minikube update-check
CurrentVersion: v0.25.0
LatestVersion: v0.26.1
To upgrade minikube simply type minikube delete
which deletes your current minikube installation and download the new release as described.
$ minikube delete
There is a newer version of minikube available (v0.26.1). Download it here:
https://github.com/kubernetes/minikube/releases/tag/v0.26.1
To disable this notification, run the following:
minikube config set WantUpdateNotification false
