這裡的「操作」指的是 HTTP 的「方法」之一。

其中包括：

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

……以及更少見的：

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

在 HTTP 協定中，你可以使用這些「方法」之一（或更多）與每個路徑進行通信。

在建置 API 時，你通常使用這些特定的 HTTP 方法來執行特定的動作。

通常你使用：

* `POST`：用來建立資料。
* `GET`：用來讀取資料。
* `PUT`：用來更新資料。
* `DELETE`：用來刪除資料。

所以，在 OpenAPI 中，每個 HTTP 方法都被稱為「操作」。

我們將會稱它們為「**操作**」。

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

...흔히 사용되지 않는 것들도 있습니다:

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

HTTP 프로토콜에서는 이러한 "메소드"를 하나(또는 이상) 사용하여 각 경로와 통신할 수 있습니다.

---

API를 설계할 때 일반적으로 특정 행동을 수행하기 위해 특정 HTTP 메소드를 사용합니다.

일반적으로 다음과 같습니다:

* `POST`: 데이터를 생성하기 위해.
* `GET`: 데이터를 읽기 위해.
* `PUT`: 데이터를 수정하기 위해.
* `DELETE`: 데이터를 삭제하기 위해.

  phase (Succeeded or Failed, depending on the exit statuses of the pod containers) to pods which
  are deleted while running.
