How do I create a PVC from a Volume Snapshot to a Kubernetes cluster? It is tuck in "pending" state
Hey there! Wondering if I could get some help with a k8s, PVCs, and volume backup restoration.
Got an app in Cluster A with Postgres, which keeps data in a volume created via a PVC resource, and we’re migrating to a new Cluster B.
Cluster A - Kubernetes 1.18.14-do.0
Cluster B - Kubernetes 1.20.2-do.0
What I want to do
Use the PVC data from Cluster A and attach it to the app in Cluster B.
What I tried
Created a backup snapshot of the volume from Cluster A and attempted to create a new PVC in Cluster B from it following the tutorial in
Cluster B - pvc.yaml
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: pg-data namespace: pipeline labels: environment: prod spec: dataSource: name: pg-data-backup kind: VolumeSnapshot apiGroup: snapshot.storage.k8s.io accessModes: - ReadWriteOnce resources: requests: storage: 1Gi # same size as that of the PVC from Cluster A
What I am seeing
The new PVC in Cluster B is stuck in Pending status, as shown below.
kubectl get persistentvolumeclaims -n pipeline NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE pg-data Pending do-block-storage 39m
Am I doing something wrong? Any ideas or guidance would be hugely appreciated.
