Docker Desktop is a application that allows you to create and share containerized apps. Docker Desktop is a preferred choice because it can be used with any language or development tool you choose, and also gives you access unlimited images and templates from Docker Hub. Docker Desktop includes the following components: Docker Engine, Client Docker CLI, Docker Compose, Docker Content Trust, Kubernetes, Credential helper. In this article, you will learn how to install docker desktop on ubuntu.

System requirements

This setup works best if your Linux host meets these specifications:

  • Virtualization support with 64-bit CPU and kernel
  • Memory greater than 4GB
  • QEMU must be at least version 5.2
  • Gnome Desktop Environment or KDE Desktop Environment
  • Systemd Init system.
  • KVM virtualization support

This is necessary because Docker Desktop Linux runs a Virtual Machine, (VM).

 

Docker Desktop Introduction

Docker Desktop is a preferred choice because it can be used with any language or development tool you choose, and also gives you access unlimited images and templates from Docker Hub. This allows you to quickly extend your environment and integrate, auto-build and collaborate through a secure repository.

Other features of Docker Desktop include:

  • Easy to install – This makes it simple to set up a Docker environment for your development.
  • Automatic updates – This ensures up-to-date versions and security
  • Reliable performance with native Windows Hyper-V virtualization
  • Ease of management – Automate the installation, scaling and management of containerized workloads. Windows allows you to switch between Linux and Windows Server environments when building applications.
  • Volume mounting of code and data. Includes file change notifications. Easy access to run containers on the localhost network.
  • IDEs support for in-container development, debugging and bug fixing
  • Share apps on any cloud platform – It allows you to containerize and share your applications in multiple languages and frameworks.

 

Why Linux developers need Docker Desktop?

Linux developers waited for this product because they wanted a unified Docker experience on all major operating systems. This could be Ubuntu(DEB), Red Hat (RPM) and Arch Linux(Pacman). It is still difficult to install and maintain Docker binaries across all of these Linux platforms. Maintaining the latest Docker releases requires refreshing the repository indexes, and making sure that the system packaging management does not break.

This new product makes it easy to keep your Docker version current and officially supported by Docker Team. The Docker Desktop UI now makes it easier to manage images, volumes, and containers, and also provides insight into the Docker processes that are running on your machine. Docker Desktop also allows you to run Kubernetes. It’s not easy to install Kubernetes. That’s why there are many Kubernetes tools on the market. Docker Desktop makes it easy to install and maintain Kubernetes latest versions on your desktop.

If you have installed the Docker Desktop for Linux tech preview or beta version, you need to remove all files that were generated by those packages (e.g., ~/.config/systemd/user/docker-desktop.service, ~/.local/share/systemd/user/docker-desktop.service).

 

Deinstall the Tech Preview or Beta Version of Docker Desktop Linux. Run the command below:

sudo apt remove docker-desktop

For a complete cleanup, remove configuration and data files at $HOME/.docker/desktop, the symlink at /usr/local/bin/com.docker.cli, and purge the remaining systemd service files.

rm -r $HOME/.docker/desktop
sudo rm /usr/local/bin/com.docker.cli
sudo apt purge docker-desktop

For non-Gnome Desktop environments gnome terminal must also be installed

sudo apt-install gnome terminal

Install Docker Engine

 

Proceed and set up the Docker repository on your Ubuntu machine. First, remove the existing repository.

sudo apt update

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker-archive-keyring.gpg
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
