# QingStor

> Mount a QingStor (QingCloud) Object Storage bucket via its S3-compatible API.

The QingStor resource is a thin wrapper over the [S3 resource](/python/resource/s3).
It maps a `QingStorConfig` to an `S3Config` and reuses the exact same backend,
commands, and behavior as S3, it just derives the right endpoint from `region`
(the QingStor zone). Uses aioboto3 against QingStor's S3-compatible API.

The endpoint is computed from `region` as `s3.<region>.qingstor.com`
(e.g. `s3.pek3a.qingstor.com`). This is QingStor's S3-compatible host, distinct
from the native `<zone>.qingstor.com` API. Pass `endpoint_url` to override.

## Config

```python theme={null}
import os

from mirage import MountMode, Workspace
from mirage.resource.qingstor import QingStorConfig, QingStorResource

config = QingStorConfig(
    bucket=os.environ["QINGSTOR_BUCKET"],
    region=os.environ.get("QINGSTOR_ZONE", "pek3a"),
    access_key_id=os.environ["QINGSTOR_ACCESS_KEY_ID"],
    secret_access_key=os.environ["QINGSTOR_SECRET_ACCESS_KEY"],
    # Optional:
    # endpoint_url="https://s3.pek3a.qingstor.com",
    # timeout=30,
    # proxy="http://proxy:8080",
)
resource = QingStorResource(config)
ws = Workspace({"/data": resource}, mode=MountMode.READ)
```

Both `READ` and `WRITE` modes are supported.

## Example

```python theme={null}
import asyncio
import os

from dotenv import load_dotenv

from mirage import MountMode, Workspace
from mirage.resource.qingstor import QingStorConfig, QingStorResource

load_dotenv(".env.development")

config = QingStorConfig(
    bucket=os.environ["QINGSTOR_BUCKET"],
    region=os.environ.get("QINGSTOR_ZONE", "pek3a"),
    endpoint_url=os.environ.get("QINGSTOR_ENDPOINT_URL"),
    access_key_id=os.environ["QINGSTOR_ACCESS_KEY_ID"],
    secret_access_key=os.environ["QINGSTOR_SECRET_ACCESS_KEY"],
)
resource = QingStorResource(config)


async def main() -> None:
    ws = Workspace({"/data/": resource}, mode=MountMode.READ)

    r = await ws.execute("ls /data/")
    print(await r.stdout_str())

    r = await ws.execute("find /data/ -name '*.json' | head -n 5")
    print(await r.stdout_str())


if __name__ == "__main__":
    asyncio.run(main())
```

## Notes

* QingStor reports `ResourceName.S3` and routes through the same `core/s3`
  implementation, so the full S3 shell-command set applies. See the
  [S3 resource](/python/resource/s3) for the complete command reference,
  range reads, streaming, and the index cache fast path.
* For credential setup, see [QingStor Setup](/home/setup/qingstor).
