    Prerequisites:

Run minikube with kvm driver by $ minikube start --vm-driver kvm

Minio FS mode:

Deploy minio in fs mode with below yaml in a file like $ kubectl create -f my-minio-fs.yaml

## Create persistent volume claim for minio to store data.
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: my-minio-fs-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

## Run minio fs deployment.
apiVersion: extensions/v1
kind: Deployment
metadata:
  name: my-minio-fs
spec:
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: my-minio-fs
    spec:
      volumes:
      - name: data
        persistentVolumeClaim:
          claimName: my-minio-fs-pvc
      containers:
      - name: my-minio-fs
        volumeMounts:
        - name: data 
          mountPath: "/data"
        image: minio/minio:RELEASE.2017-11-22T19-55-46Z
        args:
        - server
        - /data
        env:
        - name: MINIO_ACCESS_KEY
          value: "minio"
        - name: MINIO_SECRET_KEY

        ports:
        - containerPort: 9000
          hostPort: 9000

To make the above deployment accessible from outside network, run below command

$ kubectl expose deployment/my-minio-fs --type="NodePort" --port 9000

Run below command to know the port the above service exposed.

kubectl get services/my-minio-fs -o go-template='{{(index .spec.ports 0).nodePort}}'

Use this port in the endpoint http://minikube:<EXPOSED-PORT>
