Update to the Docker Desktop terms

Commercial use of Docker Desktop in larger enterprises (more than 250 employees OR more than $10 million USD in annual revenue) now requires a paid subscription. The grace period for those that will require a paid subscription ends on January 31, 2022. Learn more{: target="blank" rel="noopener" class="" id="dkr_docs_cta"}. {: .important}

Welcome to Docker Desktop for Linux. This page contains information about Docker Desktop for Linux system requirements, download URLs, instructions to install and update Docker Desktop for Linux.

Download Docker Desktop for Linux packages

DEB{: .button .primary-btn } RPM{: .button .primary-btn }

System requirements

Your Linux host must meet the following requirements to install Docker Desktop successfully:

  • 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 newer. We recommend upgrading to the latest version.

  • systemd init system

  • Gnome or KDE Desktop environment

  • At least 4 GB of RAM.

Docker Desktop for Linux runs a Virtual Machine (VM). For more information on why, see here.

Note:

Docker does not provide support for running Docker Desktop in nested virtualization scenarios. We recommend that you run Docker Desktop for Linux natively on the supported distributions.

Supported platforms

Docker provides .deb and .rpm packages from the following Linux distributions and architectures:

{% assign yes = 'yes{: .inline style="height: 14px; margin: 0 auto"}' %}

Platform x86_64 / amd64
Ubuntu {{ yes }}
Debian {{ yes }}
Fedora {{ yes }}

Note:

An experimental package is available for Arch-based distributions. Docker has not tested or verified the installation.

Docker supports Docker Desktop on the current LTS release of the aforementioned distributions and the most recent version. As new versions are made generally available, Docker stops supporting the oldest version and supports the newest version.

KVM virtualization support

Docker Desktop runs a VM that requires KVM support.

The kvm module should load automatically if the host has virtualization support. To load the module manually run:

$ modprobe kvm

Depending on the processor of the host machine, the coresponding module must be loaded:

$ modprobe kvm_intel  # Intel processors

$ modprobe kvm_amd    # AMD processors

To check the KVM modules have been enabled:

$ lsmod | grep kvm
kvm_amd               167936  0
ccp                   126976  1 kvm_amd
kvm                  1089536  1 kvm_amd
irqbypass              16384  1 kvm

Set up KVM device user permissions

Check ownership of /dev/kvm, run :

$ ls -al /dev/kvm

Add your user to the kvm group in order to access the kvm device.

$ sudo usermod -aG kvm $USER

Log out and log back in so that your group membership is re-evaluated.

Generic installation steps

  1. Download the correct package for your Linux distribution and install it with the corresponding package manager.

  2. Open your Applications menu in Gnome/KDE Desktop and search for Docker Desktop.

    Docker app in Applications

  3. Double-click Docker Desktop to start Docker.

  4. The Docker menu (whale menu{: .inline}) displays the Docker Subscription Service Agreement window. It includes a change to the terms of use for Docker Desktop.

    {% include desktop-license-update.md %}

  5. Click the checkbox to accept the updated terms and then click Accept to continue. Docker Desktop starts after you accept the terms.

    Important

    If you do not agree to the terms, the Docker Desktop application will close and you can no longer run Docker Desktop on your machine. You can choose to accept the terms at a later date by opening Docker Desktop. {: .important}

    For more information, see Docker Desktop License Agreement. We recommend that you also read the Blog{: target="blank" rel="noopener" class="" id="dkr_docs_desktop_install_btl"} and FAQs{: target="blank" rel="noopener" class="" id="dkr_docs_desktop_install_btl"} to learn how companies using Docker Desktop may be affected.

Quick start guide

If you've just installed the app, Docker Desktop launches the Quick Start Guide. The tutorial includes a simple exercise to build an example Docker image, run it as a container, push and save the image to Docker Hub.

Docker Quick Start tutorial

Congratulations! You are now successfully running Docker Desktop. Click the Docker menu (whale menu{: .inline}) to see Settings and other options. To run the Quick Start Guide on demand, select the Docker menu and then choose Quick Start Guide.

Updates

Once a new version for Docker Desktop is released, the Docker UI shows a notification. You need to download the new package each time you want to upgrade manually. To upgrade your installation of Docker Desktop, first stop any instance of Docker Desktop running locally, then follow the regular installation steps to install the new version on top of the existing version.

Uninstall Docker Desktop

Docker Desktop can be removed from a Linux host using the package manager.

Once Docker Desktop has been removed, users must remove the credsStore and currentContext properties from the ~/.docker/config.json.

Note

Uninstalling Docker Desktop destroys Docker containers, images, volumes, and other Docker related data local to the machine, and removes the files generated by the application. Refer to the back up and restore data section to learn how to preserve important data before uninstalling.
