Other Linux distributions

While the instructions below may work, Docker does not test or verify installation on derivatives.

• Users of Debian derivatives such as “BunsenLabs Linux”, “Kali Linux” or “LMDE” (Debian-based Mint) should follow the installation instructions for Debian, substituting the version of their distro for the corresponding Debian release. Refer to the documentation of your distro to find which Debian release corresponds with your derivative version.
• Likewise, users of Ubuntu derivatives such as “Kubuntu”, “Lubuntu” or “Xubuntu” should follow the installation instructions for Ubuntu, substituting the version of their distro for the corresponding Ubuntu release. Refer to the documentation of your distro to find which Ubuntu release corresponds with your derivative version.
• Some Linux distributions are providing a package of Docker Engine through their package repositories. These packages are built and maintained by the Linux distribution’s package maintainers and may have differences in configuration or built from modified source code. Docker is not involved in releasing these packages and bugs or issues involving these packages should be reported in your Linux distribution’s issue tracker.

Docker provides binaries for manual installation of Docker Engine. These binaries are statically linked and can be used on any Linux distribution.

Release channels

Docker Engine has three types of update channels, stable, test, and nightly:

• The Stable channel gives you latest releases for general availability.
• The Test channel gives pre-releases that are ready for testing before general availability (GA).
• The Nightly channel gives you latest builds of work in progress for the next major release.

Stable

Year-month releases are made from a release branch diverged from the master branch. The branch is created with format . , for example 20.10 . The year-month name indicates the earliest possible calendar month to expect the release to be generally available. All further patch releases are performed from that branch. For example, once v20.10.0 is released, all subsequent patch releases are built from the 20.10 branch.

In preparation for a new year-month release, a branch is created from the master branch with format YY.mm when the milestones desired by Docker for the release have achieved feature-complete. Pre-releases such as betas and release candidates are conducted from their respective release branches. Patch releases and the corresponding pre-releases are performed from within the corresponding release branch.

Nightly

Nightly builds give you the latest builds of work in progress for the next major release. They are created once per day from the master branch with the version format:

where the time is the commit time in UTC and the final suffix is the prefix of the commit hash, for example 0.0.0-20180720214833-f61e0f7 .

These builds allow for testing from the latest code on the master branch. No qualifications or guarantees are made for the nightly builds.

Support

Docker Engine releases of a year-month branch are supported with patches as needed for one month after the next year-month general availability release.

This means bug reports and backports to release branches are assessed until the end-of-life date.

After the year-month branch has reached end-of-life, the branch may be deleted from the repository.

Backporting

Backports to the Docker products are prioritized by the Docker company. A Docker employee or repository maintainer will endeavour to ensure sensible bugfixes make it into active releases.

If there are important fixes that ought to be considered for backport to active release branches, be sure to highlight this in the PR description or by adding a comment to the PR.

Upgrade path

Patch releases are always backward compatible with its year-month version.

Licensing

Docker is licensed under the Apache License, Version 2.0. See LICENSE for the full license text.

Reporting security issues

The Docker maintainers take security seriously. If you discover a security issue, please bring it to their attention right away!

Please DO NOT file a public issue; instead send your report privately to security@docker.com.

Security reports are greatly appreciated, and Docker will publicly thank you for it.

Install Docker Engine on Ubuntu

Estimated reading time: 12 minutes

Docker Desktop for Linux

Docker Desktop helps you build, share, and run containers easily on Mac and Windows as you do on Linux. Docker handles the complex setup and allows you to focus on writing the code. Thanks to the positive support we received on the subscription updates, we’ve started working on Docker Desktop for Linux which is the second-most popular feature request in our public roadmap. If you are interested in early access, sign up for our Developer Preview program.

To get started with Docker Engine on Ubuntu, make sure you meet the prerequisites, then install Docker.

Prerequisites

OS requirements

To install Docker Engine, you need the 64-bit version of one of these Ubuntu versions:

• Ubuntu Hirsute 21.04
• Ubuntu Focal 20.04 (LTS)
• Ubuntu Bionic 18.04 (LTS)

Docker Engine is supported on x86_64 (or amd64 ), armhf , arm64 , and s390x architectures.

Ubuntu 16.04 LTS “Xenial Xerus” end-of-life

Ubuntu Linux 16.04 LTS reached the end of its five-year LTS window on April 30th 2021 and is no longer supported. Docker no longer releases packages for this distribution (including patch- and security releases). Users running Docker on Ubuntu 16.04 are recommended to update their system to a currently supported LTS version of Ubuntu.

Uninstall old versions

Older versions of Docker were called docker , docker.io , or docker-engine . If these are installed, uninstall them:

It’s OK if apt-get reports that none of these packages are installed.

The contents of /var/lib/docker/ , including images, containers, volumes, and networks, are preserved. If you do not need to save your existing data, and want to start with a clean installation, refer to the uninstall Docker Engine section at the bottom of this page.

Supported storage drivers

Docker Engine on Ubuntu supports overlay2 , aufs and btrfs storage drivers.

Docker Engine uses the overlay2 storage driver by default. If you need to use aufs instead, you need to configure it manually. See use the AUFS storage driver

Installation methods

You can install Docker Engine in different ways, depending on your needs:

Most users set up Docker’s repositories and install from them, for ease of installation and upgrade tasks. This is the recommended approach.

Some users download the DEB package and install it manually and manage upgrades completely manually. This is useful in situations such as installing Docker on air-gapped systems with no access to the internet.

In testing and development environments, some users choose to use automated convenience scripts to install Docker.

Install using the repository

Before you install Docker Engine for the first time on a new host machine, you need to set up the Docker repository. Afterward, you can install and update Docker from the repository.

Set up the repository

Update the apt package index and install packages to allow apt to use a repository over HTTPS:

Add Docker’s official GPG key:

Use the following command to set up the stable repository. To add the nightly or test repository, add the word nightly or test (or both) after the word stable in the commands below. Learn about nightly and test channels.

Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such as xenial . Sometimes, in a distribution like Linux Mint, you might need to change $(lsb_release -cs) to your parent Ubuntu distribution. For example, if you are using Linux Mint Tessa , you could use bionic . Docker does not offer any guarantees on untested and unsupported Ubuntu distributions.

Install Docker Engine

Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:

Got multiple Docker repositories?

If you have multiple Docker repositories enabled, installing or updating without specifying a version in the apt-get install or apt-get update command always installs the highest possible version, which may not be appropriate for your stability needs.

To install a specific version of Docker Engine, list the available versions in the repo, then select and install:

a. List the versions available in your repo:

b. Install a specific version using the version string from the second column, for example, 5:18.09.1

Verify that Docker Engine is installed correctly by running the hello-world image.

This command downloads a test image and runs it in a container. When the container runs, it prints a message and exits.

Docker Engine is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands. Continue to Linux postinstall to allow non-privileged users to run Docker commands and for other optional configuration steps.

Upgrade Docker Engine

To upgrade Docker Engine, first run sudo apt-get update , then follow the installation instructions, choosing the new version you want to install.

Install from a package

If you cannot use Docker’s repository to install Docker Engine, you can download the .deb file for your release and install it manually. You need to download a new file each time you want to upgrade Docker.

Go to https://download.docker.com/linux/ubuntu/dists/ , choose your Ubuntu version, then browse to pool/stable/ , choose amd64 , armhf , arm64 , or s390x , and download the .deb file for the Docker Engine version you want to install.

To install a nightly or test (pre-release) package, change the word stable in the above URL to nightly or test . Learn about nightly and test channels.

Install Docker Engine, changing the path below to the path where you downloaded the Docker package.

The Docker daemon starts automatically.

Verify that Docker Engine is installed correctly by running the hello-world image.

This command downloads a test image and runs it in a container. When the container runs, it prints a message and exits.

Docker Engine is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands. Continue to Post-installation steps for Linux to allow non-privileged users to run Docker commands and for other optional configuration steps.

Upgrade Docker Engine

To upgrade Docker Engine, download the newer package file and repeat the installation procedure, pointing to the new file.

Install using the convenience script

Docker provides a convenience script at get.docker.com to install Docker into development environments quickly and non-interactively. The convenience script is not recommended for production environments, but can be used as an example to create a provisioning script that is tailored to your needs. Also refer to the install using the repository steps to learn about installation steps to install using the package repository. The source code for the script is open source, and can be found in the docker-install repository on GitHub.

Always examine scripts downloaded from the internet before running them locally. Before installing, make yourself familiar with potential risks and limitations of the convenience script:

• The script requires root or sudo privileges to run.
• The script attempts to detect your Linux distribution and version and configure your package management system for you, and does not allow you to customize most installation parameters.
• The script installs dependencies and recommendations without asking for confirmation. This may install a large number of packages, depending on the current configuration of your host machine.
• By default, the script installs the latest stable release of Docker, containerd, and runc. When using this script to provision a machine, this may result in unexpected major version upgrades of Docker. Always test (major) upgrades in a test environment before deploying to your production systems.
• The script is not designed to upgrade an existing Docker installation. When using the script to update an existing installation, dependencies may not be updated to the expected version, causing outdated versions to be used.

Tip: preview script steps before running

You can run the script with the DRY_RUN=1 option to learn what steps the script will execute during installation:

This example downloads the script from get.docker.com and runs it to install the latest stable release of Docker on Linux:

Docker is installed. The docker service starts automatically on Debian based distributions. On RPM based distributions, such as CentOS, Fedora, RHEL or SLES, you need to start it manually using the appropriate systemctl or service command. As the message indicates, non-root users cannot run Docker commands by default.

Use Docker as a non-privileged user, or install in rootless mode?

The installation script requires root or sudo privileges to install and use Docker. If you want to grant non-root users access to Docker, refer to the post-installation steps for Linux. Docker can also be installed without root privileges, or configured to run in rootless mode. For instructions on running Docker in rootless mode, refer to run the Docker daemon as a non-root user (rootless mode).

Install pre-releases

Docker also provides a convenience script at test.docker.com to install pre-releases of Docker on Linux. This script is equivalent to the script at get.docker.com , but configures your package manager to enable the “test” channel from our package repository, which includes both stable and pre-releases (beta versions, release-candidates) of Docker. Use this script to get early access to new releases, and to evaluate them in a testing environment before they are released as stable.

To install the latest version of Docker on Linux from the “test” channel, run:

Upgrade Docker after using the convenience script

If you installed Docker using the convenience script, you should upgrade Docker using your package manager directly. There is no advantage to re-running the convenience script, and it can cause issues if it attempts to re-add repositories which have already been added to the host machine.

Uninstall Docker Engine

Uninstall the Docker Engine, CLI, and Containerd packages:

Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:

You must delete any edited configuration files manually.
