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)

See: volume.get (Python SDK), volume.get (TypeScript SDK)

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)

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

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 }],
})

See: CreateSandboxFromSnapshotParams (Python SDK), CreateSandboxFromSnapshotParams (TypeScript SDK)

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.

Python
TypeScript

# Write to a file in the mounted volume
with open("/home/daytona/volume/example.txt", "w") as f:
    f.write("Hello from Daytona volume!")

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

import fs from 'fs/promises'

// Write to a file in the mounted volume
await fs.writeFile('/home/daytona/volume/example.txt', 'Hello from Daytona volume!')

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

Deleting Volumes

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

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)

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.
