> Mount one or more volumes to a sandbox at custom paths when creating it.

You can mount one or more volumes to a sandbox when creating it. The keys of the `volumeMounts` / `volume_mounts` object are the mount paths inside the sandbox.

```js title="JavaScript & TypeScript"
import { Volume, Sandbox } from 'e2b'

const volume = await Volume.create('my-volume')

// You can pass a Volume object
const sandbox = await Sandbox.create({
  volumeMounts: {
    '/mnt/my-data': volume,
  },
})

// Or pass the volume name directly
const sandbox = await Sandbox.create({
  volumeMounts: {
    '/mnt/my-data': 'my-volume',
  },
})

// Files written to /mnt/my-data inside the sandbox are persisted in the volume
await sandbox.files.write('/mnt/my-data/hello.txt', 'Hello, world!')
```

```python title="Python"
from e2b import Volume, Sandbox

volume = Volume.create('my-volume')

# You can pass a Volume object
sandbox = Sandbox.create(
    volume_mounts={
        '/mnt/my-data': volume,
    },
)

# Or pass the volume name directly
sandbox = Sandbox.create(
    volume_mounts={
        '/mnt/my-data': 'my-volume',
    },
)

# Files written to /mnt/my-data inside the sandbox are persisted in the volume
sandbox.files.write('/mnt/my-data/hello.txt', 'Hello, world!')
