Что нужно знать перед установкой
Системные требования
- Windows 10 64-бит: Pro, Enterprise или Education (Сборка 15063 или более поздняя).
- Функции Hyper-V и Containers Windows должны быть активны.
- Минимальные требования для запуска клиента Hyper-V на Windows 10:
- 64 битный процессор с функцией Second Level Address Translation (SLAT)
- 4GB оперативной памяти
- На уровне BIOS должна быть включена поддержка виртуализации. Подробнее о виртуализации можно прочитать здесь.
README для пользователей Docker Toolbox и Docker Machine: для запуска Docker Desktop требуется поддержка Microsoft Hyper-V. Установщик Docker Desktop Windows при необходимости активирует Hyper-V и перезапускает машину. Если Hyper-V активирован VirtualBox не будет работать. Однако все существующие образы VirtualBox останутся.
Виртуальные машины VirtualBox созданные с помощью docker-machine (включая default машину обычно создаваемую во время установки Toolbox) больше запускаться не будут. These VMs cannot be used side-by-side with Docker Desktop. However, you can still use docker-machine to manage remote VMs.
Что включает в себя установщик
Установщик Docker Desktop включает в себя Docker Engine, клиент Docker CLI, Docker Compose, Notary, Kubernetes, и Credential Helper.Контейнеры и образы созданные в Docker Desktop будут доступны для всех пользовательских аккаунтов. are shared between all user accounts on machines where it is installed. Это происходит по тому что все Windows аккаунты используют одну виртуальную машину для билда и запуска контейнеров.
Вложенные сценарии вертуализации, такие как Docker Desktop в VMWare или Parallels могут работать, но нет гарантий. Более подробно читайте в разделе запуск Docker Desktop в вложенных сценариях виртуализации.
Примечание: Refer to the Docker compatibility matrix for complete Docker compatibility information with Windows Server.
О контейнерах в Windows
Looking for information on using Windows containers?- Switch between Windows and Linux containers describes how you can toggle between Linux and Windows containers in Docker Desktop and points you to the tutorial mentioned above.
- Getting Started with Windows Containers (Lab) provides a tutorial on how to set up and run Windows containers on Windows 10, Windows Server 2016 and Windows Server 2019. It shows you how to use a MusicStore application with Windows containers.
- Docker Container Platform for Windows articles and blog posts on the Docker website.
Install Docker Desktop on Windows
- Double-click Docker Desktop Installer.exe to run the installer.
If you haven't already downloaded the installer (Docker Desktop Installer.exe), you can get it from Docker Hub. It typically downloads to your Downloads folder, or you can run it from the recent downloads bar at the bottom of your web browser. - Follow the instructions on the installation wizard to accept the license, authorize the installer, and proceed with the install.
When prompted, authorize the Docker Desktop Installer with your system password during the install process. Privileged access is needed to install networking components, links to the Docker apps, and manage the Hyper-V VMs. - Click Finish on the setup complete dialog and launch the Docker Desktop application.
Start Docker Desktop
Docker Desktop does not start automatically after installation. To start Docker Desktop, search for Docker, and select Docker Desktop in the search results.
When the whale icon in the status bar stays steady, Docker Desktop is up-and-running, and is accessible from any terminal window.
If the whale icon is hidden in the Notifications area, click the up arrow on the taskbar to show it. To learn more, see Docker Settings.
After installing the Docker Desktop app, you also get a pop-up success message with suggested next steps, and a link to this documentation.
When initialization is complete, click the whale icon in the Notifications area and select About Docker Desktop to verify that you have the latest version.
Congratulations! You are successfully running Docker Desktop on Windows.
Uninstall Docker Desktop
To uninstall Docker Desktop from your Windows machine:- From the Windows Start menu, select Settings > Apps > Apps & features.
- Select Docker Desktop from the Apps & features list and then select Uninstall.
- Click Uninstall to confirm your selection.
Switch between Stable and Edge versions
Docker Desktop allows you to switch between Stable and Edge releases. However, you can only have one version of Docker Desktop installed at a time. Switching between Stable and Edge versions can destabilize your development environment, particularly in cases where you switch from a newer (Edge) channel to an older (Stable) channel.For example, containers created with a newer Edge version of Docker Desktop may not work after you switch back to Stable because they may have been created using Edge features that aren't in Stable yet. Keep this in mind as you create and work with Edge containers, perhaps in the spirit of a playground space where you are prepared to troubleshoot or start over.
To safely switch between Edge and Stable versions, ensure you save images and export the containers you need, then uninstall the current version before installing another. For more information, see the section Save and Restore data below.
Save and restore data
You can use the following procedure to save and restore images and container data. For example, if you want to switch between Edge and Stable, or to reset your VM disk:- Use docker save -o images.tar image1 [image2 ...] to save any images you want to keep. See save in the Docker Engine command line reference.
- Use docker export -o myContainner1.tar container1 to export containers you want to keep. See export in the Docker Engine command line reference.
- Uninstall the current version of Docker Desktop and install a different version (Stable or Edge), or reset your VM disk.
- Use docker load -i images.tar to reload previously saved images. See load in the Docker Engine.
- Use docker import -i myContainer1.tar to create a file system image corresponding to the previously exported containers. See import in the Docker Engine.
