you are setting `--redirect-container-streaming=true`, then you must migrate off this configuration. The flag will no longer be able to be enabled starting in v1.20. If you are not setting the flag, no action is necessary. ([#88290](https://github.com/kubernetes/kubernetes/pull/88290), [@tallclair](https://github.com/tallclair)) [SIG API Machinery and Node]

3. 將需求檔案複製到 `/code` 目錄。

    先只複製需求檔案，不要複製其他程式碼。

    因為這個檔案不常變動，Docker 能偵測並在此步驟使用快取，也能啟用下一步的快取。

4. 安裝需求檔案中的套件相依。

    `--no-cache-dir` 選項告訴 `pip` 不要把下載的套件保存在本機，因為那只在 `pip` 之後還會再次安裝相同套件時才有用，而在使用容器時並非如此。

    /// note | 注意

    `--no-cache-dir` 只跟 `pip` 有關，與 Docker 或容器無關。

    ///

    `--upgrade` 選項告訴 `pip` 若套件已安裝則升級它們。

    因為前一步複製檔案可能被 Docker 快取偵測到，這一步也會在可用時使用 Docker 快取。
