I have been trying to deploy Cassandra using following documentation https://kubernetes.io/docs/tutorials/stateful-application/cassandra/
deployment of Cassandra works fine but when i try to create statefull set it gives following error :
Cassandra 0 pod has unbound immediate PersistentVolumeClaims (repeated 2 times)
can any one help me where am i doing wrong ?
Did you create correct storage class and named it fast?
Try with this one:
...
volumeClaimTemplates:
- metadata:
name: cassandra-data
spec:
accessModes: [ "ReadWriteOnce" ]
storageClassName: fast
resources:
requests:
storage: 1Gi
---
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: fast
parameters:
fsType: xfs
kind: Managed
storageaccounttype: Premium_LRS
provisioner: kubernetes.io/azure-disk
reclaimPolicy: Delete
volumeBindingMode: ImmediateA stateful set requires a persistent volume where store the state, the docs you provide there is a section that shows it:
volumeClaimTemplates:
- metadata:
name: cassandra-data
spec:
accessModes: [ "ReadWriteOnce" ]
storageClassName: fast
resources:
requests:
storage: 1Gi
---
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
name: fast
provisioner: k8s.io/minikube-hostpath
parameters:
type: pd-ssdthese are the docs to create a PV and/or Storage class in Azure as you need
https://docs.microsoft.com/en-us/azure/aks/azure-files-dynamic-pv
then you can associate the object with your StatefulSet
