I am using Kubernetes static PV to mount my Postgresql data. But I am unable to do this
Here is my YAML file where I create PV , PVC and my Postgres pod
my data directory of Postgres located at “/var/lib/pgsql/9.3/data”
But initially, my data directory /var/lib/pgsql/9.3/data is nonempty. I already append some sample data here. I want that Kubernetes will create the volume in the same location and mount it to /mnt/data
I also provide permissions and ownership but my problem still not fixed. The same thing works fine if I use docker volume
apiVersion: v1 kind: PersistentVolume metadata: name: task-pv-volume namespace: manhattan labels: type: local spec: storageClassName: manual capacity: storage: 100Mi accessModes: - ReadWriteOnce hostPath: path: "/mnt/data" --- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: task-pv-claim namespace: manhattan spec: storageClassName: manual accessModes: - ReadWriteOnce resources: requests: storage: 80Mi --- apiVersion: v1 kind: Pod metadata: name: dbr-postgres namespace: manhattan spec: volumes: - name: task-pv-storage persistentVolumeClaim: claimName: task-pv-claim containers: - name: task-pv-container image: postgresql:2.0.1 tty: true volumeMounts: - mountPath: "/var/lib/pgsql/9.3/data" name: task-pv-storage subPath: data readOnly: false nodeSelector: kubernetes.io/hostname: k8s-master
Can anyone tell me what I am doing wrong?
