```
export MINIO_ETCD_ENDPOINTS=http://localhost:2379
minio server /data
```

NOTE: If `etcd` is configured with `Client-to-server authentication with HTTPS client certificates` then you need to use additional envs such as `MINIO_ETCD_CLIENT_CERT` pointing to path to `etcd-client.crt` and `MINIO_ETCD_CLIENT_CERT_KEY` path to `etcd-client.key` .

### 4. Test with MinIO STS API

This is supported since FastAPI version `0.115.0`. 🤓

## Header Parameters with a Pydantic Model

Declare the **header parameters** that you need in a **Pydantic model**, and then declare the parameter as `Header`:

## Deprecate a *path operation*

If you need to mark a *path operation* as <abbr title="obsolete, recommended not to use it">deprecated</abbr>, but without removing it, pass the parameter `deprecated`:
