Istiod's primary role - and most code - is to dynamically configure proxies (Envoy sidecars and ingress, gRPC, ztunnel, and more). This roughly consists of 3 parts:
1. Config ingestion (inputs to the system)
1. Config translation
1. Config serving (XDS)

### Config Ingestion

    - injects the CNI plugin config to the CNI config file
        - CNI installer will try to look for the config file under the mounted CNI net dir based on file name extensions (`.conf`, `.conflist`)
        - the file name can be explicitly set by `CNI_CONF_NAME` env var
        - the program inserts `CNI_NETWORK_CONFIG` into the `plugins` list in `/etc/cni/net.d/${CNI_CONF_NAME}`

Und dann aktualisieren Sie Ihre `config.py` mit:

=== "Pydantic v2"

    ```Python hl_lines="9"
    {!> ../../../docs_src/settings/app03_an/config.py!}
    ```

    !!! tip "Tipp"

    ```bash
    export flags="--config=opt -k"
    ```

    If the tests are to be run on the GPU, add CUDA paths to LD_LIBRARY_PATH and
    add the `cuda` option flag

    ```bash
    export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/local/cuda/lib64:/usr/local/cuda/extras/CUPTI/lib64:$LD_LIBRARY_PATH"
    export flags="--config=opt --config=cuda -k"
    ```

    {!> ../../../docs_src/settings/app03_an/config_pv1.py!}
    ```

    !!! tip
        The `Config` class is used just for Pydantic configuration. You can read more at <a href="https://docs.pydantic.dev/1.10/usage/model_config/" class="external-link" target="_blank">Pydantic Model Config</a>.

### 从 `.env` 文件中读取设置

然后，您可以使用以下方式更新您的 `config.py`：

```Python hl_lines="9-10"
{!../../../docs_src/settings/app03/config.py!}
```

在这里，我们在 Pydantic 的 `Settings` 类中创建了一个名为 `Config` 的类，并将 `env_file` 设置为我们想要使用的 dotenv 文件的文件名。

!!! tip
    `Config` 类仅用于 Pydantic 配置。您可以在<a href="https://docs.pydantic.dev/latest/api/config/" class="external-link" target="_blank">Pydantic Model Config</a>中阅读更多相关信息。

To support WebIdentity based login for MinIO Console, set openid configuration and restart MinIO

```
mc admin config set myminio identity_openid config_url="<CONFIG_URL>" client_id="<client_identifier>"
```

```
mc admin service restart myminio
```
