What specific changes need to be made to the yaml below in order to get the PersistentVolumeClaim to bind to the PersistentVolume?
An EC2 instance in the same VPC subnet as the Kubernetes worker nodes has an ip of 10.0.0.112 and and has been configured to act as an NFS server in the /nfsfileshare path.
We created a PersistentVolume pv01 with pv-volume-network.yaml:
apiVersion: v1
kind: PersistentVolume
metadata:
name: pv01
spec:
capacity:
storage: 5Gi
volumeMode: Filesystem
accessModes:
- ReadWriteMany
persistentVolumeReclaimPolicy: Recycle
storageClassName: slow
mountOptions:
- hard
- nfsvers=4.1
nfs:
path: "/nfsfileshare"
server: "10.0.0.112"and by typing:
kubectl create -f pv-volume-network.yamlThen when we type kubectl get pv pv01, the pv01 PersistentVolume shows a STATUS of "Available".
Then we created a PersistentVolumeClaim named `` with pv-claim.yaml:
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: my-pv-claim
spec:
storageClassName: manual
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 3GiAnd by typing:
kubectl create -f pv-claim.yamlBut then when we type kubectl get pvc my-pv-claim, we see that the STATUS is Pending. The STATUS remains as Pending for as long as we continued to check back.
Note this OP is different than this other question, because this problem persists even with quotes around the NFS IP and the path.
Why is this PVC not binding to the PV? What specific changes need to be made to resolve this?
I diagnosed the problem by typing kubectl describe pvc my-pv-claim and looking in the Events section of the results.
Then, based on the reported Events, I was able to fix this by changing storageClassName: manual to storageClassName: slow.
The problem was that the PVC's StorageClassName did not meet the requirement that it match the class specified in the PV.
