## Uninstalling the Chart

To uninstall/delete the chart:

```console
helm delete ztunnel
```

## Configuration

To view support configuration options and documentation, run:

```console
helm show values istio/ztunnel
```

### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
These can be set with `--set profile=<profile>`.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.

```

## Additional Responses

You probably have seen how to declare the `response_model` and `status_code` for a *path operation*.

                <version>2.10.3</version>
                <configuration>
                    <stylesheetfile>${basedir}/src/main/javadoc/stylesheet.css</stylesheetfile>
                    <show>protected</show>
                    <author>false</author>
                    <version>false</version>
                    <detectLinks>false</detectLinks>
                    <linksource>true</linksource>

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

## Alternative (old) `Query` as the default value

To uninstall/delete the `istiod` deployment:

```console
helm delete istiod --namespace istio-system
```

## Configuration

To view support configuration options and documentation, run:

```console
helm show values istio/istiod
```

### Profiles

Istio Helm charts have a concept of a `profile`, which is a bundled collection of value presets.
These can be set with `--set profile=<profile>`.

But you can disable it by setting `syntaxHighlight` to `False`:

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial001.py!}
```

...and then Swagger UI won't show the syntax highlighting anymore:

## Change the Theme

```

Default config includes most common highly compressible content extensions and mime-types.

```bash
~ mc admin config set myminio compression extensions=".pdf" mime_types="application/pdf"
```

To show help on setting compression config values.

```bash
~ mc admin config set myminio compression
```

To enable compression for all content, no matter the extension and content type

But I'll show you how to improve that next. 🤓

## Custom Operation IDs and Better Method Names

You can **modify** the way these operation IDs are **generated** to make them simpler and have **simpler method names** in the clients.

It can be configured via MinIO's standard configuration API (i.e. using `mc admin config set/get`), or equivalently with environment variables. For brevity we show only environment variables here:

```sh
$ mc admin config set myminio identity_plugin --env
KEY:
identity_plugin  enable Identity Plugin via external hook

ARGS:

'system-node-critical' outside of kube-system.
