Scan your images for vulnerabilities

Using open source components in your container images can introduce vulnerabilities. Run docker scan to start securing your images using Snyk. If you have a Docker Pro, Team, or a Business subscription, you can automatically scan images when you push an image to Docker Hub. See Hub Vulnerability Scanning for more information.

To get started with Docker Engine on Ubuntu, make sure youmeet the prerequisites, theninstall Docker.

Prerequisites

OS requirements

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

  • 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 April30th 2021 and is no longer supported. Docker no longer releases packages forthis distribution (including patch- and security releases). Users runningDocker on Ubuntu 16.04 are recommended to update their system to a currentlysupported 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, andnetworks, are preserved. If you do not need to save your existing data, and want tostart with a clean installation, refer to the uninstall Docker Enginesection 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 useaufs 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:

How To Install Docker Compose On Ubuntu 20.04

  • Most usersset up Docker’s repositories and installfrom them, for ease of installation and upgrade tasks. This is therecommended approach.

  • Some users download the DEB package andinstall it manually and manageupgrades completely manually. This is useful in situations such as installingDocker on air-gapped systems with no access to the internet.

  • In testing and development environments, some users choose to use automatedconvenience scripts to install Docker.

Install using the repository

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

Set up the repository

  1. Update the apt package index and install packages to allow apt to use arepository over HTTPS:

  2. Add Docker’s official GPG key:

  3. Use the following command to set up the stable repository. To add thenightly 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 yourUbuntu distribution, such as xenial. Sometimes, in a distributionlike 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 untestedand unsupported Ubuntu distributions.

Install Docker Engine

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

    Got multiple Docker repositories?

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

  2. To install a specific version of Docker Engine, list the available versionsin 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, 5:18.09.1~3-0~ubuntu-xenial.

  3. Verify that Docker Engine is installed correctly by running the hello-worldimage.

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

Docker Engine is installed and running. The docker group is created but no usersare added to it. You need to use sudo to run Docker commands.Continue to Linux postinstall to allow non-privilegedusers 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 theinstallation instructions, choosing the newversion 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 downloada new file each time you want to upgrade Docker.

  1. 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 Engineversion you want to install.

    Note

    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.

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

    The Docker daemon starts automatically.

  3. Verify that Docker Engine is installed correctly by running the hello-worldimage.

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

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

Upgrade Docker Engine

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

Install using the convenience script

Docker provides a convenience script at get.docker.comto install Docker into development environments quickly and non-interactively.The convenience script is not recommended for production environments, but can beused as an example to create a provisioning script that is tailored to your needs.Also refer to the install using the repositorysteps 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 thedocker-install repository on GitHub.

Install docker-compose ubuntu 20.04 lts

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

Install
  • The script requires root or sudo privileges to run.
  • The script attempts to detect your Linux distribution and version andconfigure your package management system for you, and does not allow you tocustomize most installation parameters.
  • The script installs dependencies and recommendations without asking forconfirmation. This may install a large number of packages, depending on thecurrent 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 inunexpected major version upgrades of Docker. Always test (major) upgrades ina test environment before deploying to your production systems.
  • The script is not designed to upgrade an existing Docker installation. Whenusing the script to update an existing installation, dependencies may not beupdated 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 thescript will execute during installation:

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

Docker is installed. The docker service starts automatically on Debian baseddistributions. 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.

Install Docker Compose On Ubuntu 20.04

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

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

Install

Install pre-releases

Docker also provides a convenience script at test.docker.comto install pre-releases of Docker on Linux. This script is equivalent to thescript at get.docker.com, but configures your package manager to enable the“test” channel from our package repository, which includes both stable andpre-releases (beta versions, release-candidates) of Docker. Use this script toget early access to new releases, and to evaluate them in a testing environmentbefore 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 Dockerusing your package manager directly. There is no advantage to re-running theconvenience script, and it can cause issues if it attempts to re-addrepositories which have already been added to the host machine.

Uninstall Docker Engine

  1. Uninstall the Docker Engine, CLI, and Containerd packages:

  2. Images, containers, volumes, or customized configuration files on your hostare not automatically removed. To delete all images, containers, andvolumes:

You must delete any edited configuration files manually.
