description: Mount a self-hosted MinIO bucket as a virtual filesystem.

The MinIO resource is a thin wrapper over the [S3 resource](/python/resource/s3).
It maps a `MinIOConfig` to an `S3Config` and reuses the exact same backend,
commands, and behavior as S3, it just points at your MinIO `endpoint_url` and
uses path-style addressing by default.

MinIO is self-hosted, so `endpoint_url` is **required** (there is no
region-derived host). Uses aioboto3 against MinIO's S3-compatible API.

## Config

```python
import os

from mirage import MountMode, Workspace
from mirage.resource.minio import MinIOConfig, MinIOResource

config = MinIOConfig(
    bucket=os.environ["MINIO_BUCKET"],
    endpoint_url=os.environ.get("MINIO_ENDPOINT", "http://localhost:9000"),
    access_key_id=os.environ["MINIO_ACCESS_KEY"],
    secret_access_key=os.environ["MINIO_SECRET_KEY"],
    # Optional:
    # region="us-east-1",   # default
    # path_style=True,      # default; MinIO requires path-style addressing
    # timeout=30,
    # proxy="http://proxy:8080",
)
resource = MinIOResource(config)
ws = Workspace({"/minio": resource}, mode=MountMode.WRITE)
```

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

## Example

```python
import asyncio
import os

from dotenv import load_dotenv

from mirage import MountMode, Workspace
from mirage.resource.minio import MinIOConfig, MinIOResource

load_dotenv(".env.development")

config = MinIOConfig(
    bucket=os.environ.get("MINIO_BUCKET", "mirage-demo"),
    endpoint_url=os.environ.get("MINIO_ENDPOINT", "http://localhost:9000"),
    access_key_id=os.environ.get("MINIO_ACCESS_KEY", "minioadmin"),
    secret_access_key=os.environ.get("MINIO_SECRET_KEY", "minioadmin"),
)
resource = MinIOResource(config)


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

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

    r = await ws.execute("tree /minio/")
    print(await r.stdout_str())

    r = await ws.execute("cat /minio/data/config.json")
    print(await r.stdout_str())


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

## Notes

- MinIO reports `ResourceName.S3` and routes through the same `core/s3`
  implementation, so the full S3 shell-command set applies (`ls`, `cat`,
  `head`, `tail`, `grep`, `rg`, `wc`, `find`, `tree`, `jq`, `stat`, plus
  parquet/orc/feather table rendering). See the [S3 resource](/python/resource/s3)
  for the complete command reference, range reads, streaming, and the index
  cache fast path.
