Before you create Kubernetes volumes, you must first create a storage class. Use following command to create a StorageClass called longhorn.

    1. kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/master/examples/storageclass.yaml

    Now you can create a pod using Longhorn like this:

    1. kubectl create -f https://raw.githubusercontent.com/longhorn/longhorn/master/examples/pvc.yaml

    The above yaml file contains two parts:

    1. Create a PVC using Longhorn StorageClass.
    1. apiVersion: v1
    2. kind: PersistentVolumeClaim
    3. metadata:
    4.   name: longhorn-volv-pvc
    5. spec:
    6.   accessModes:
    7.     - ReadWriteOnce
    8.   storageClassName: longhorn
    9.   resources:
    10.     requests:
    11.       storage: 2Gi
    1. Use it in the a Pod as a persistent volume:
    1. apiVersion: v1
    2. kind: Pod
    3. metadata:
    4.   name: volume-test
    5.   namespace: default
    6. spec:
    7.   containers:
    8.   - name: volume-test
    9.     image: nginx:stable-alpine
    10.     imagePullPolicy: IfNotPresent
    11.     volumeMounts:
    12.     - name: volv
    13.       mountPath: /data
    14.     ports:
    15.     - containerPort: 80
    16.   volumes:
    17.   - name: volv
    18.     persistentVolumeClaim:
    19.       claimName: longhorn-volv-pvc
