Volumes

Volumes are FUSE-based mounts that provide shared file access across Sandboxes. They allow Sandboxes to read from large files instantly - no need to upload files manually to each Sandbox. Volume data is stored on an S3-compatible object store.

Multiple volumes can be mounted to a single Sandbox
A single volume can be mounted to multiple Sandboxes

Creating Volumes

Before mounting a volume to a Sandbox, it must be created.

Python
TypeScript

volume = daytona.volume.get("my-volume", create=True)

const volume = await daytona.volume.get('my-volume', true)

Mounting Volumes

Once a volume is created, it can be mounted to a Sandbox by specifying it in the CreateSandboxFromSnapshotParams object:

Python
TypeScript

import os
from daytona import CreateSandboxFromSnapshotParams, Daytona, VolumeMount

daytona = Daytona()

# Create a new volume or get an existing one

volume = daytona.volume.get("my-volume", create=True)

# Mount the volume to the sandbox

mount_dir_1 = "/home/daytona/volume"

params = CreateSandboxFromSnapshotParams(
    language="python",
    volumes=[VolumeMount(volumeId=volume.id, mountPath=mount_dir_1)],
)
sandbox = daytona.create(params)

# When you're done with the sandbox, you can remove it

# The volume persists after the sandbox is removed

sandbox.delete()

import { Daytona } from '@daytonaio/sdk'
import path from 'path'

async function main() {
  const daytona = new Daytona()

  //  Create a new volume or get an existing one
  const volume = await daytona.volume.get('my-volume', true)

  // Mount the volume to the sandbox
  const mountDir1 = '/home/daytona/volume'

  const sandbox1 = await daytona.create({
    language: 'typescript',
    volumes: [{ volumeId: volume.id, mountPath: mountDir1 }],
  })

  // When you're done with the sandbox, you can remove it
  // The volume will persist even after the sandbox is removed
  await sandbox1.delete()
}

main()

Deleting Volumes

When a volume is no longer needed, it can be removed.

Python
TypeScript

volume = daytona.volume.get("my-volume", create=True)
daytona.volume.delete(volume)

const volume = await daytona.volume.get('my-volume', true)
await daytona.volume.delete(volume)

Working with Volumes

Once mounted, you can read from and write to the volume just like any other directory in the Sandbox file system. Files written to the volume persist beyond the lifecycle of any individual Sandbox.

Limitations

Since volumes are FUSE-based mounts, they can not be used for applications that require block storage access (like database tables). Volumes are generally slower for both read and write operations compared to the local Sandbox file system.
