Error "pod has unbound immediate PersistentVolumeClaim" during statefulset deployment

10/29/2019

I am deploying stolon via statefulset (default from stolon repo). I have define in statefulset config

volumeClaimTemplates:     
    - metadata:    
        name: data   
      spec:   
        accessModes: ["ReadWriteOnce"]   
        storageClassName: stolon-local-storage  
        resources:
          requests:
            storage: 1Gi

and here is my storageClass:

apiVersion: storage.k8s.io/v1   
kind: StorageClass   
metadata:   
  name: stolon-local-storage  
provisioner: kubernetes.io/no-provisioner  
volumeBindingMode: WaitForFirstConsumer

statefulset was created fine, but pod has error: pod has unbound immediate PersistentVolumeClaims

How can I resolve it?

pod has unbound immediate PersistentVolumeClaims

In this case pvc could not connect to storageclass because it wasn't make as a default.

Depending on the installation method, your Kubernetes cluster may be deployed with an existing StorageClass that is marked as default. This default StorageClass is then used to dynamically provision storage for PersistentVolumeClaims that do not require any specific storage class. See PersistentVolumeClaim documentation for details.

Command which can be used to make your new created storageclass a default one.

kubectl patch storageclass <name_of_storageclass> -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

Then You can use kubectl get storageclass and it should look like this

NAME                 PROVISIONER               AGE
stolon-local-storage   (default)   kubernetes.io/gce-pd      1d
