I recently started exploring Kubernetes and decided to try and deploy kafka to k8s. However I have a problem with creating the persistent volume. I create a storage class and a persistent volume, but the persistent volume claims stay in status pending saying "no volume plugin matched". This is the yaml files I used with the dashed lines denoting a new file. Anybody has an idea why this is happening?
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: Immediate
reclaimPolicy: Retain
------------------------
apiVersion: v1
kind: PersistentVolume
metadata:
name: kafka-pv
spec:
capacity:
storage: 10Gi
volumeMode: Filesystem
accessModes:
- ReadWriteOnce
persistentVolumeReclaimPolicy: Retain
storageClassName: local-storage
local:
path: /mnt/disks/ssd1
nodeAffinity:

nodeSelectorTerms:

---------------------------
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: zookeeper-pvc
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 5Gi
storageClassName: local-storageYou have to bound Persistent-volume claim with your persistent volume. As you have mentioned pvc storageclassName: local-storage. try it with as storageclassName: kafka-pv So that your pvc get bounded to pv.
Your Persistent Volume Claim configuration file should look like this:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: zookeeper-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 5Gi
storageClassName: local-storageJust change access mode from ReadWriteMany to ReadWriteOnce.
Let me know if it helped.
As MaggieO said changing ReadWriteMany to ReadWriteOnce was part of the problem. The other part was that I had to go and create the /mnt/disks/ssd1 folder on my C: drive manually and write "path: /c/mnt/disks/ssd1" instead. Something that is not present in my example, but I was trying to do anyway and might be helpful to others was that I was trying to have two PVCs for one PV which is impossible. The PV to PVC relationship is 1 to 1.
