Upload Images to DO Volume attached to Droplet

I’m currently building a blog using a MEVN stack. My Kubernetes cluster runs on DO (otherwise I wouldn’t be here).

I’ve been trying to figure out how exactly to get my images into this volume I created and I have no idea how to do it. I also don’t know how I would retrieve the images as well.

I’ll show you guys my node backend to show you guys what I’m doing so far.

const express = require('express');
const path = require('path');
const Posts = require('../db/models/post');
const router = express.Router();
const multer = require('multer');

const storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, './uploads/');
  filename: function (req, file, cb) {
    cb(null, file.originalname)

const fileFilter = (req, file, cb) => {
  if (file.mimetype === 'image/jpeg' || file.mimetype === 'image/png') {
    cb(null, true);
  else {
    cb(null, false);

const upload = multer({
  storage: storage,
  limit: {
    fileSize: 1024 * 1024 * 5
  fileFilter: fileFilter
});"/createPost",upload.single('img'), (req, res) => {
  let currDate = new Date().toISOString();
  let post = req.body;
  post.postId = Math.floor((Math.random() * 9999999) + 1000000); = currDate;
  post.img = req.file.path;
  post = new Posts(post);
  console.log(req.body); => {
    res.status(200).send("Post has been uploaded");
    .catch(() => {
      res.status(400).send("unable to post");


Locally all my files will save to /uploads/ but how do I configure it to save to my volume and then how do I get the images from my volume as well?

Hi there @astronik,

What I would personally do in this case is to mount the volume to the uploads directory.

That way you will not have to change your application in any way, so when you upload images they would again be uploaded to the uploads folder and as the volume is mounted to that uploads directory, the images will be saved on a persistent volume.

Hope that this helps.
