Yesterday, I installed kubernetes microk8s on my private laptop to learn about kubernetes, But even on first simple file with PersistentVolume I'm getting a lot of validation errors,

I have installed microk8s on Ubuntu from below source: https://microk8s.io/?_ga=2.70856272.1723042697.1642604373-620897147.1642604373v

The issue is when firstly I wanted to create pv:

apiVersion: v1
kind: PersistentVolume
metadata:
name: redis-pv
spec:
storageClassName: ""
capacity:
storage: 1Gi
accessModes:
- ReadWriteOnce
hostPath:
path: "/mnt/data"

and I'm gettting below errors:

kubectl apply -f pv-data.yml -n testing

error: error validating "pv-data.yml": error validating data: [ValidationError(PersistentVolume): unknown field "accessModes" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "name" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "path" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "storage" in io.k8s.api.core.v1.PersistentVolume, ValidationError(PersistentVolume): unknown field "storageClassName" in io.k8s.api.core.v1.PersistentVolume]; if you choose to ignore these errors, turn validation off with --validate=false

Can someone help me with that ? Maybe I have microk8s not properly installed ? Because this is very simple yaml file.

also I would like to attach status of microk8s:

microk8s status
