Vercel Sandbox now supports FUSE
Vercel Sandbox now supports FUSE, letting you mount remote storage and custom filesystems inside a running Sandbox. Use it to attach S3 buckets, network filesystems, or any other FUSE-compatible driver as a regular path.
import { Sandbox } from '@vercel/sandbox';
const sandbox = await Sandbox.create();
// Install Mountpoint for Amazon S3 (official release) and its FUSE dependency.await sandbox.runCommand({ sudo: true, cmd: 'dnf', args: [ 'install', '-y', 'fuse', 'https://s3.amazonaws.com/mountpoint-s3-release/latest/x86_64/mount-s3.rpm', ],});
const MOUNT_DIR = '/mnt/s3'
await sandbox.runCommand({ sudo: true, cmd: 'mkdir', args: ['-p', MOUNT_DIR]});
// Pass aws credentials only to the mount-s3 command.// Note: this does expose the credentials permanently in the sandbox!// Use a restricted role onlyawait sandbox.runCommand({ sudo: true, cmd: 'mount-s3', args: [ process.env.S3_BUCKET_NAME, MOUNT_DIR, '--allow-other', ], env: { AWS_ACCESS_KEY_ID: process.env.AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY: process.env.AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN: process.env.AWS_SESSION_TOKEN, AWS_REGION: process.env.AWS_REGION },});
// List the files in your bucketawait sandbox.runCommand({ cmd: 'ls', args: ['-la', MOUNT_DIR], stdout: process.stdout,});
await sandbox.stop();
Run s3fs inside of a Vercel Sandbox
This makes it possible to stream large datasets directly from object storage, share state across Sandboxes through a common filesystem, or run tools that expect POSIX paths against remote sources without copying data into the Sandbox first.
