title: Databricks Volume
|
|
icon: folder-open
|
|
description: Set up the Databricks Unity Catalog volume resource in Python.
|
|
---
|
|
|
|
## Dependencies
|
|
|
|
```bash
|
|
uv add 'mirage-ai[databricks]'
|
|
```
|
|
|
|
For credential setup, see the [Databricks Volume Setup](/home/setup/databricks)
|
|
guide.
|
|
|
|
## Configuration
|
|
|
|
### Databricks Apps or SDK-default auth
|
|
|
|
```python
|
|
from mirage import Workspace, MountMode
|
|
from mirage.resource.databricks_volume import (
|
|
DatabricksVolumeConfig,
|
|
DatabricksVolumeResource,
|
|
)
|
|
|
|
config = DatabricksVolumeConfig(
|
|
catalog="main",
|
|
schema="default",
|
|
volume="agent_files",
|
|
)
|
|
resource = DatabricksVolumeResource(config=config)
|
|
ws = Workspace({"/dbx/": resource}, mode=MountMode.READ)
|
|
```
|
|
|
|
### Explicit host and token
|
|
|
|
```python
|
|
import os
|
|
|
|
config = DatabricksVolumeConfig(
|
|
catalog="main",
|
|
schema="default",
|
|
volume="agent_files",
|
|
host=os.environ["DATABRICKS_HOST"],
|
|
token=os.environ["DATABRICKS_TOKEN"],
|
|
root_path="/reports",
|
|
)
|
|
resource = DatabricksVolumeResource(config=config)
|
|
ws = Workspace({"/dbx/": resource}, mode=MountMode.READ)
|
|
```
|
|
|
|
### Profile-based auth
|
|
|
|
```python
|
|
config = DatabricksVolumeConfig(
|
|
catalog="main",
|
|
schema="default",
|
|
volume="agent_files",
|
|
profile="DEV",
|
|
)
|
|
resource = DatabricksVolumeResource(config=config)
|
|
ws = Workspace({"/dbx/": resource}, mode=MountMode.READ)
|
|
```
|
|
|
|
## Config Reference
|
|
|
|
| Field | Required | Default | Description |
|
|
| --- | --- | --- | --- |
|
|
| `catalog` | Yes | | Unity Catalog catalog name. |
|
|
| `schema` | Yes | | Unity Catalog schema name. |
|
|
| `volume` | Yes | | Unity Catalog volume name. |
|
|
| `root_path` | No | `/` | Subdirectory inside the volume to expose. |
|
|
| `host` | No | | Databricks workspace host. |
|
|
| `token` | No | | Databricks personal access token. Redacted in snapshots. |
|
|
| `profile` | No | | Databricks SDK profile name. |
|
|
| `timeout` | No | `30` | Request timeout in seconds. |
|
|
|
|
## Notes
|
|
|
|
- Supports both read and write mount modes (`MountMode.READ` / `MountMode.WRITE`).
|
|
- Auth falls through to the Databricks SDK defaults when `host`, `token`, and `profile` are omitted.
|
|
- `root_path` is normalized and cannot contain `..`.
