Эта статья даст вам полное представление о Docker Desktop для пользователей Windows и MAC. Мы изучим установку Docker Desktop на компьютерах с Windows и Mac. После установки мы также попытаемся выполнить некоторые операции Docker.

Docker Desktop — это собственное настольное приложение, разработанное Docker для пользователей Windows и MAC. Это самый простой способ запуска, сборки, отладки и тестирования приложений Dockerized.

Docker Desktop предлагает важные и наиболее полезные функции, такие как быстрые циклы редактирования, уведомления об изменениях файлов, встроенная поддержка корпоративной сети и гибкость для работы с собственным выбором прокси и VPN.

Docker Desktop состоит из инструментов для разработчика, приложения Docker, Kubernetes и синхронизации версий. Он позволяет вам создавать сертифицированные образы и шаблоны языков и инструментов.

Скорость, безопасность и выбор — все, что вам нужно для разработки и доставки контейнерных приложений, доступных на вашем рабочем столе, будет представлено вам.

Прежде чем перейти к процессу установки, давайте разберемся с его версиями.

Версии Docker

Docker в основном поставляется в двух версиях, в Community и ENterprise.

Community версия поставляется с бесплатным набором продуктов Docker. ENterprise корпоративная версия представляет собой сертифицированную контейнерную платформу, которая предоставляет коммерческим пользователям дополнительные функции, такие как безопасность образов, управление образами, оркестровка и управление средой выполнения контейнеров, но по разумной цене.

Мы начнем наше обучение с Community Edition. Контейнеры Docker, работающие в конкретной операционной системе, совместно используют ядро ​​ОС. Это означает, что мы не можем использовать ядро ​​Windows (хост) для запуска контейнеров Linux или наоборот. Чтобы проделать это, у нас есть Docker Desktop для Windows и MAC.

Выпуски Docker Desktop

Docker Desktop выпускается в двух вариантах.

  • Stable: как видно из названия, стабильный выпуск тщательно протестирован и может быть использован при разработке более надежных приложений. Его версии полностью синхронизированы с версиями Docker Engine.
  • Edge: эти версии состоят из всех новых и экспериментальных функций Docker Engine. Есть больше шансов ошибок, сбоев и проблем, которые могут возникнуть. Тем не менее, пользователи получат возможность ознакомиться с предстоящими функциями.

Docker на Windows

Есть два варианта Docker на Windows.

1. Использование Docker Toolbox

Docker Toolbox предоставляет набор легких инструментов.

  • Oracle virtual box
  • Docker Engine
  • Docker Machine
  • Docker compose
  • Kitematic GUI

Вышеуказанные инструменты устраняют необходимость развертывания отдельной виртуальной машины для запуска Docker. Просто установите исполняемый файл панели инструментов Docker непосредственно в Windows и начните разработку приложений. Требуется 64-битная ОС и Windows 7 или выше с включенным режимом виртуализации.

Но опять же, панель инструментов Docker — это оригинальная поддержка, предоставляемая в Windows для запуска Docker и его устаревшего решения для всех ОС Windows, которые не соответствуют требуемой конфигурации.

2. Использование Docker Desktop

Docker Desktop — это новейшая технология, используемая для Docker в Windows. Он заменяет виртуальную машину Oracle собственной технологией виртуализации, доступной в Windows, то есть Microsoft Hyper-V.

Он по-прежнему будет запускать Docker на Linux-машине, созданной под ним. Но на этот раз вместо виртуальной машины Oracle мы использовали нативный Microsoft Hyper-V.

Установка Docker на Windows

Вы можете скачать репозиторий Docker Desktop из Docker Hub.

Установка Docker на Windows

истемные требования:

  • Windows 10 или Windows Server 2016 Professional или Enterprise Edition
  • Поддержка Hyper-V.

Чтобы запустить Hyper-V, оборудование должно соответствовать следующим требованиям:

  • 64-битный процессор
  • > = 4 ГБ ОЗУ
  • Поддержка виртуализации оборудования на уровне BIOS

Следовательно, программная и аппаратная зависимость заключается в запуске Docker Desktop на Windows.

Установка Docker на macOS

Вы можете скачать репозиторий Docker Desktop из Docker Hub.  

Установка Docker на macOS

Системные требования:

  • MAC Hardware 2010 или новее с аппаратной поддержкой управления памятью и неограниченным режимом. Выполните команду kern.hv_support, чтобы проверить, поддерживает ли оборудование MAC инфраструктуру гипервизора.
  • MAC OS версии 10.13 или новее.
  • > = 4 ГБ ОЗУ
  • Virtual-Box до версии 4.3.30

Работа с образами

После установки проверьте версию установленного Docker Engine.

docker --version

Docker работает с доставкой и запуском контейнерных приложений. Вам либо нужно создать свое собственное контейнерное приложение, либо Docker поддерживает контейнерные образы в Docker Hub, и его можно легко загрузить с помощью простой команды docker run.

Здесь мы будем тянуть образ Redis.

docker pull redis

docker образ redis

С помощью простой команды run образы можно скачивать и загружать на GitHub или Docker Hub, и любой пользователь во всем мире может получить к нему доступ и начать работать с ним.

Docker Container запускает образ Docker. Следующим шагом является запуск контейнера.

docker run -p 6379 Redis

docker запуск redis

Будет создан зашифрованный идентификатор контейнера. Вы можете быстро проверить состояние работающего экземпляра в Docker, нажав на Dashboard option.

Docker Desktop

Обязательно остановите контейнер, прежде чем удалять его из Docker Engine.

Docker Desktop

Возможности Docker Desktop

Существует множество преимуществ:

  • Поддерживает широкий спектр инструментов разработки.
  • Обеспечьте быстрый и оптимизированный способ создания и публикации контейнерного образа на любой облачной платформе.
  • Простота установки и настройки полной среды Docker
  • Повышение производительности благодаря встроенной виртуализации Hyper-V для Windows и HyperKit для MAC.
  • Возможность работать в Linux через WSL 2 на компьютерах с Windows.
  • Легкий доступ к работающим контейнерам в локальной сети.
  • Возможность поделиться любым приложением на облачной платформе, на разных языках и в разных средах.
  • Для обеспечения безопасности и актуальности выполняются автоматические обновления.
  • Включены последние версии Kubernetes.
  • Возможность переключения между Linux и Windows сервером на Windows.

Docker Desktop — это нативное приложение, разработанное на Windows и MAC OS для запуска, сборки и доставки контейнерных приложений или сервисов.

Однако

Docker Desktop предназначен не для производственной среды, а для рабочего стола и среды разработки.

Docker Desktop for Windows is a version of the Docker platform that is designed to work on Windows operating systems. It allows developers to create, deploy, and run containerised applications on their Windows development machine. To run Windows containers, you need Windows 10 or Windows 11 Professional or Enterprise edition. Windows Home or Education editions will only allow you to run Linux containers.

Docker Desktop uses Hyper-V

Internally, Docker Desktop for Windows uses the Hyper-V technology built into Windows to create a lightweight virtual machine (VM) that runs the Docker Engine. This VM runs a minimal Linux distribution, such as Moby Linux, which is specifically designed to support the Docker Engine.

When you run a container on Docker Desktop for Windows, the Docker Engine in the VM creates a new container process and isolates it from the host operating system using the Linux kernel’s built-in containerization features. The container process runs inside the VM, but it can access the host’s filesystem, network, and other resources through a set of virtualized interfaces provided by the Docker Engine.

Components of Docker Desktop for Windows

Image1

In Docker Desktop for Windows, the various components you mentioned are part of the overall architecture that provides an easy-to-use environment for building, shipping, and running Docker containers. Here’s a brief description of each component:

1. Bootstrapper

The bootstrapper is the component responsible for setting up and starting the Docker engine in Windows. It performs tasks such as installing the Docker engine and configuring the necessary environment variables.

2. Life Cycle Controller

The life cycle controller is responsible for managing the lifecycle of containers, such as starting and stopping containers, and managing the resources allocated to containers.

The Windows native symlinks are visible within the containers as symlinks, whereas symlinks created inside a container are represented as mfsymlinks. These are regular Windows files with a special metadata. Therefore the symlinks created inside a container appear as symlinks inside the container, but not on the host.

3.Docker Proxy

The Docker proxy is a component that provides a secure, encrypted connection between the Docker client and the Docker engine. It acts as a bridge between the client and the engine, and helps to ensure that sensitive information, such as authentication credentials, are transmitted securely.

4. DockerD (Windows)

DockerD (Windows) is the Docker daemon that runs in the background on Windows. It communicates with the Docker client and provides the necessary resources to run containers.

5. CLI Plugins

CLI plugins are components that extend the functionality of the Docker client by adding new commands and options. They can be installed to add support for new technologies or to provide additional functionality beyond what is provided by the base Docker client.

These components work together to provide an easy-to-use environment for building, shipping, and running Docker containers on Windows. They allow users to manage containers, interact with Docker Hub, and access the Docker engine, all from a single, user-friendly interface.

6. Docker Integrated Package

In Docker Desktop for Windows, the Docker Integrated package is a feature that allows you to run the Docker daemon and client directly inside the Windows Subsystem for Linux 2 (WSL 2) virtual machine (VM) that Docker Desktop creates. This allows you to run Linux containers natively on the Windows host, without the need for a separate virtual machine (VM) to run the Docker Engine.

When you enable the Docker Integrated package in WSL 2, the Docker daemon and client are installed inside the WSL 2 VM, and the Docker Engine runs natively on the Linux kernel that WSL 2 uses. This means that you can use the Docker command line and API directly inside the WSL 2 VM, just as you would on a Linux machine.

The Docker Integrated package also allows you to access the host’s filesystem, network, and other resources from inside the WSL 2 VM. This is done by mapping the host’s resources to the WSL 2 file system and network interfaces, which makes them available to the Docker daemon and client running inside the WSL 2 VM.

The Docker Integrated package also includes an integration with the Windows Docker client, which allows you to use the Docker command line and API from the Windows host, while the actual container runs on the WSL 2 VM.

With the Docker Integrated package, you can use the same Docker commands and configuration files that you use on Linux, and you can run the same Linux containers that you would run on a Linux machine. This makes it easy to switch between Windows and Linux development environments without having to learn new tools or workflows.

Please note that the Docker Integrated package is an experimental feature and it’s still in development.

7. Docker Proxy

The Docker Proxy is a feature of Docker Desktop for Windows that allows you to run Linux containers on the Windows host, by routing the container’s network traffic through a proxy that runs inside the Windows Subsystem for Linux 2 (WSL 2) virtual machine (VM).

When you run a Linux container on Docker Desktop for Windows, the Docker Engine creates a new container process and isolates it from the host operating system using the Linux kernel’s built-in containerization features. However, the container process runs inside the WSL 2 VM, which is isolated from the host network and cannot access the host’s network resources directly.

The Docker Proxy feature allows the container to access the host’s network resources by routing the container’s network traffic through a proxy that runs inside the WSL 2 VM. The proxy listens for incoming traffic on the host’s loopback interface and forwards it to the container running inside the WSL 2 VM. This allows the container to access the host’s network resources, such as the host’s IP address and ports, as if it were running directly on the host.

The Docker Proxy feature also allows you to access the container’s network resources from the host, by routing the host’s network traffic to the container through the proxy. This allows you to access the container’s services, such as web servers or databases, using the host’s IP address and ports.

The Docker Proxy feature is enabled by default when you run Linux containers on Docker Desktop for Windows, and it’s transparent to the user.

Additionally, Docker Desktop for Windows allows you to run both Linux and Windows container at the same time by leveraging Windows Subsystem for Linux (WSL) 2. With this setup, you can run Linux containers on the WSL 2 virtualized Linux kernel, while still having access to the host’s resources.

Docker Desktop for Windows also includes a built-in Kubernetes engine, which allows you to deploy, scale and manage containerized applications using Kubernetes.

8. Containerd

In Docker Desktop for Windows, containerd is a core component that runs on the Windows host and provides the container runtime for the Docker Engine. It works in conjunction with the Windows Subsystem for Linux 2 (WSL 2) to enable running Linux containers on Windows.

When you run a Linux container, the Docker Engine sends a request to containerd to start the container. containerd then uses WSL 2 to launch a lightweight virtual machine (VM) that runs the container process inside. This VM runs a minimal Linux distribution, such as Alpine Linux, that is specifically designed to support the container runtime.

The container process runs inside the WSL 2 VM, but it can access the host’s filesystem, network, and other resources through a set of virtualized interfaces provided by containerd. These interfaces are implemented using the 9P protocol and are mapped to the host’s resources using the WSL 2 file system and network interfaces.

containerd also provides the container runtime, which is responsible for starting and stopping container processes, and managing their lifecycle. This runtime is based on the OCI (Open Container Initiative) runtime specification, which is an open standard for container runtimes.

In summary, Docker Desktop for Windows uses containerd to run Linux containers on Windows by leveraging the WSL 2 technology. containerd provides the container runtime and handles the communication between the host and the WSL 2 VM, while WSL 2 provides the virtualization and isolation of the container process from the host.
