How to use DirectPV without MinIO

Objective:

To document how to use DirectPV without MinIO

Steps:

• Create the pod:

apiVersion: v1
kind: Pod
metadata:
  name: directpv-pod-example
  namespace: ns-3
spec:
  containers:
  - name: directpv-container
    image: busybox
    command: ["sleep", "3600"]
    volumeMounts:
    - mountPath: /data
      name: directpv-volume
  volumes:
  - name: directpv-volume
    persistentVolumeClaim:
      claimName: please-remove-me-cesar

• Create the claim:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: please-remove-me-cesar
  namespace: ns-3
  annotations:
    volume.beta.kubernetes.io/storage-provisioner: direct-csi-min-io
    volume.kubernetes.io/selected-node: minio-k8s18
  finalizers:
    - kubernetes.io/pvc-protection
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi
  storageClassName: directpv-min-io
  volumeMode: Filesystem

• Apply the claim:

kubectl apply -f /Users/cniackz/minio/claim.yaml

• Look how DirectPV bound it:

Notes:

• You have to specify the node: volume.kubernetes.io/selected-node: minio-k8s18 otherwise will be pending state.

Plan B:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: sleep-pvc
spec:
  volumeMode: Filesystem
  storageClassName: directpv-min-io
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Ki

apiVersion: v1

spec:
  nodeSelector:
    pool: one
  volumes:
    - name: sleep-volume
      persistentVolumeClaim:
        claimName: sleep-pvc
  containers:
    - name: sleep-container
      image: example.org/test/sleep:v0.0.1
      volumeMounts:
        - mountPath: "/mnt"
          name: sleep-volume
