Docker 是一個容器化軟體平台，可以用來打包、運行和分享應用程式。Docker通過容器化技術實現了應用程式的獨立性和可移植性，讓開發者和運維人員可以更加便捷地進行應用程式的開發、部署和運維。
Docker是如何運作的
加快您建置、分享和運行應用程式的速度
Docker 協助開發人員在任何地方建置、共用和運行應用程序，無需繁瑣的環境配置或管理.
建構
快速啟動新環境
使用Docker 映像開發您自己獨特的應用程序，並使用Docker Compose 建立多個容器.
與您現有的工具集成
Docker 可與所有開發工具搭配使用，例如VS Code、CircleCI 和GitHub.
將應用程式容器化以實現一致性
在從本地Kubernetes 到AWS ECS、Azure ACI、Google GKE 等的任何環境中一致運行.
分享
使用經過驗證、可信的內容進行構建
造訪 Docker Hub 瀏覽來自我們經過驗證的發布者或 Docker 官方映像的 Docker 可信任內容。
與您的團隊合作
從 Hub 中提取並發布圖像，以便在團隊成員、組織或更廣泛的社群之間輕鬆共享。
保護您的工作空間
確保影像存取管理、註冊表存取管理和私人儲存庫的最佳實踐。
運行
一致的應用程式交付
交付您的應用程式時要知道它們將在任何環境（本地或雲端）上以相同的方式運作。
多功能開發
將應用程式部署在具有多語言支援的隔離容器中，減少應用程式依賴項之間的衝突。
透過一條命令進行部署
在 Docker Compose CLI 中工作，可透過單一命令加快開發並啟動應用程式。

Important
To run Windows containers, you need Windows 10 or Windows 11 Professional or Enterprise edition. Windows Home or Education editions only allow you to run Linux containers.
Note
Docker only supports Docker Desktop on Windows for those versions of Windows that are still within Microsoft’s servicing timeline.
Install Docker Desktop on Mac
System requirements
Mac with Intel chip
A supported version of macOS.
Important
Docker supports Docker Desktop on the most recent versions of macOS. That is, the current release of macOS and the previous two releases. As new major versions of macOS are made generally available, Docker stops supporting the oldest version and supports the newest version of macOS (in addition to the previous two releases).
At least 4 GB of RAM.
Mac with Apple silicon
A supported version of macOS.

At least 4 GB of RAM.
Install Docker Desktop on Linux
System requirements
To install Docker Desktop successfully, your Linux host must meet the following general requirements:
- 64-bit kernel and CPU support for virtualization.
- KVM virtualization support. Follow the KVM virtualization support instructions to check if the KVM kernel modules are enabled and how to provide access to the KVM device.
- QEMU must be version 5.2 or later. We recommend upgrading to the latest version.
- systemd init system.
- Gnome, KDE, or MATE Desktop environment.
- For many Linux distros, the Gnome environment does not support tray icons. To add support for tray icons, you need to install a Gnome extension. For example, AppIndicator.
- At least 4 GB of RAM.
- Enable configuring ID mapping in user namespaces, see File sharing.
- Recommended: Initialize pass for credentials management.
