Install Docker Ce Linux

To install the Docker engine first, you need to update the apt of your Linux. For that, use the apt-update command from the terminal. Sudo apt-get update. After that, here we will be installing the latest and stable available version of Docker engine in the system from the Linux repository. The terminal is right here. Once the docker ce repo has been configured successfully then run following command to verify which version of docker is available for installation email protected # dnf list docker-ce Docker CE Stable - x8664 1.7 kB/s 3.8 kB 00:02 Available Packages docker-ce.x8664 3:19.03.13-3.el8 docker-ce-stable email protected #. Home of the script that lives at get.docker.com and test.docker.com! The purpose of the install script is for a convenience for quickly installing the latest Docker-CE releases on the supported linux distros. It is not recommended to depend on this script for deployment to production systems. Jan 26, 2021 Here we’ll perform an installation of Docker CE on MX Linux 19. This is a free to use edition, but without technical support from Docker Inc. If you’re keen on support consider switching to Docker Enterprise release.

  1. Install Docker Ce Amazon Linux 2
  2. Install Docker Ce Linux Mint 19
  3. Install Docker Ce On Linux Mint

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

Install

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:

  • 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.

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

  • 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.

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 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.

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

Prerequisites

Docker EE customers

To install Docker Enterprise Edition (Docker EE), go toGet Docker EE for Ubuntuinstead of this topic.

To learn more about Docker EE, seeDocker Enterprise Edition.

OS requirements

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

  • Bionic 18.04 (LTS)
  • Artful 17.10
  • Xenial 16.04 (LTS)
  • Trusty 14.04 (LTS)

Docker CE is supported on Ubuntu on x86_64, armhf, s390x (IBM Z), and ppc64le (IBM Power) architectures.

ppc64le and s390x limitations: Packages for IBM Z and Power architectures are only available on Ubuntu Xenial and above.

Uninstall old versions

Older versions of Docker were called docker or docker-engine. If these areinstalled, 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. The Docker CE package is now called docker-ce.

Supported storage drivers

Docker CE on Ubuntu supports overlay2 and aufs storage drivers.

  • For new installations on version 4 and higher of the Linux kernel, overlay2is supported and preferred over aufs.
  • For version 3 of the Linux kernel, aufs is supported because overlay oroverlay2 drivers are not supported by that kernel version.

If you need to use aufs, you need to do additional preparation asoutlined below.

Extra steps for aufs

For Ubuntu 16.04 and higher, the Linux kernel includes support for OverlayFS,and Docker CE uses the overlay2 storage driver by default. If you needto use aufs instead, you need to configure it manually.See aufs

Unless you have a strong reason not to, install thelinux-image-extra-* packages, which allow Docker to use the aufs storagedrivers.

Install Docker CE

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

  • 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 CE for the first time on a new host machine, you need toset up the Docker repository. Afterward, you can install and update Docker fromthe repository.

Set up the repository

  1. Update the apt package index:

  2. Install packages to allow apt to use a repository over HTTPS:

  3. Add Docker’s official GPG key:

    Verify that you now have the key with the fingerprint9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for thelast 8 characters of the fingerprint.

  4. Use the following command to set up the stable repository. You alwaysneed the stable repository, even if you want to install builds from theedge or test repositories as well. To add the edge ortest repository, add the word edge or test (or both) after theword stable in the commands below.

    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 Rafaela, you could use trusty.

    Note: Starting with Docker 17.06, stable releases are also pushed tothe edge and test repositories.

    Learn about stable and edge channels.

Install Docker CE

  1. Update the apt package index.

  2. Install the latest version of Docker CE, 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.

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

    a. List the versions available in your repo:

    b. Install a specific version by its fully qualified package name, which is package name (docker-ce) “=” version string (2nd column), for example, docker-ce=18.03.0~ce-0~ubuntu.

    The Docker daemon starts automatically.

  4. Verify that Docker CE 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 an informational message and exits.

Docker CE 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 allownon-privileged users to run Docker commands and for other optional configurationsteps.

Upgrade Docker CE

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

Install using the convenience script

Docker provides convenience scripts at get.docker.comand test.docker.com for installing edge andtesting versions of Docker CE into development environments quickly andnon-interactively. The source code for the scripts is in thedocker-install repository.Using these scripts is not recommended for productionenvironments, and you should understand the potential risks before you usethem:

  • The scripts require root or sudo privileges to run. Therefore,you should carefully examine and audit the scripts before running them.
  • The scripts attempt to detect your Linux distribution and version andconfigure your package management system for you. In addition, the scripts donot allow you to customize any installation parameters. This may lead to anunsupported configuration, either from Docker’s point of view or from your ownorganization’s guidelines and standards.
  • The scripts install all dependencies and recommendations of the packagemanager without asking for confirmation. This may install a large number ofpackages, depending on the current configuration of your host machine.
  • The script does not provide options to specify which version of Docker to install,and installs the latest version that is released in the “edge” channel.
  • Do not use the convenience script if Docker has already been installed on thehost machine using another mechanism.

Install Docker Ce Amazon Linux 2

This example uses the script at get.docker.com toinstall the latest release of Docker CE on Linux. To install the latesttesting version, use test.docker.com instead. Ineach of the commands below, replace each occurrence of get with test.

Warning:

Always examine scripts downloaded from the internet beforerunning them locally.

Docker CE is installed. It starts automatically on DEB-based distributions. OnRPM-based distributions, you need to start it manually using the appropriatesystemctl or service command. As the message indicates, non-root users can’trun Docker commands by default.

Upgrade Docker after using the convenience script

Install Docker Ce Linux Mint 19

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 CE

  1. Uninstall the Docker CE package:

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