docker init

描述為您的專案建立 Docker 相關啟動檔案
用法docker init [OPTIONS]
要求： Docker Desktop 4.27 及更高版本

描述

使用在容器中執行專案所需的檔案初始化專案。

Docker Desktop 提供了 `docker init` CLI 命令。在您的專案目錄中執行 `docker init` 將引導您建立以下檔案，併為您的專案提供合理的預設值：

  • .dockerignore
  • Dockerfile
  • compose.yaml
  • README.Docker.md

如果任何檔案已存在，將出現提示並提供警告，同時為您提供覆蓋所有檔案的選項。如果 `docker-compose.yaml` 而不是 `compose.yaml` 已存在，`docker init` 可以覆蓋它，並將 `docker-compose.yaml` 用作 Compose 檔案的名稱。

警告

被覆蓋的檔案無法恢復。在選擇覆蓋之前，請重新命名現有檔案或將其複製到另一個目錄以進行備份。

執行 `docker init` 後，您可以選擇以下模板之一：

  • ASP.NET Core：適用於 ASP.NET Core 應用程式。
  • Go：適用於 Go 伺服器應用程式。
  • Java：適用於使用 Maven 並打包為 uber jar 的 Java 應用程式。
  • Node：適用於 Node 伺服器應用程式。
  • 帶 Apache 的 PHP：適用於 PHP Web 應用程式。
  • Python：適用於 Python 伺服器應用程式。
  • Rust：適用於 Rust 伺服器應用程式。
  • 其他：容器化應用程式的通用起點。

在 `docker init` 完成後，您可能需要修改建立的檔案並根據您的專案進行調整。訪問以下主題以瞭解有關這些檔案的更多資訊：

> PHP with Apache - (detected) suitable for a PHP web application
  Go - suitable for a Go server application
  Java - suitable for a Java application that uses Maven and packages as an uber jar
  Python - suitable for a Python server application
  Node - suitable for a Node server application
  Rust - suitable for a Rust server application
  ASP.NET Core - suitable for an ASP.NET Core application
  Other - general purpose starting point for containerizing your application
