```console
kubectl create namespace istio-system
helm install istiod istio/istiod --namespace istio-system
```

## Uninstalling the Chart

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
```

Normalerweise verwenden Sie:

* `POST`: um Daten zu erzeugen (create).
* `GET`: um Daten zu lesen (read).
* `PUT`: um Daten zu aktualisieren (update).
* `DELETE`: um Daten zu löschen (delete).

In OpenAPI wird folglich jede dieser HTTP-Methoden als „Operation“ bezeichnet.

Wir werden sie auch „**Operationen**“ nennen.

#### Definieren eines *Pfadoperation-Dekorators*

Normally you use:

* `POST`: to create data.
* `GET`: to read data.
* `PUT`: to update data.
* `DELETE`: to delete data.

So, in OpenAPI, each of the HTTP methods is called an "operation".

We are going to call them "**operations**" too.

#### Define a *path operation decorator*

To install the chart with the release name `istio-ingressgateway`:

```console
helm install istio-ingressgateway istio/gateway
```

## Uninstalling the Chart

To uninstall/delete the `istio-ingressgateway` deployment:

```console
helm delete istio-ingressgateway
```

## Configuration

To view support configuration options and documentation, run:

```console
helm show values istio/gateway
```

这里的「操作」指的是一种 HTTP「方法」。

下列之一：

* `POST`
* `GET`
* `PUT`
* `DELETE`

...以及更少见的几种：

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

在 HTTP 协议中，你可以使用以上的其中一种（或多种）「方法」与每个路径进行通信。

---

在开发 API 时，你通常使用特定的 HTTP 方法去执行特定的行为。

通常使用：

* `POST`：创建数据。
* `GET`：读取数据。
* `PUT`：更新数据。
* `DELETE`：删除数据。

因此，在 OpenAPI 中，每一个 HTTP 方法都被称为「操作」。

我们也打算称呼它们为「操作」。
