Install Docker Engine on Ubuntu
4

To get started with Docker Engine on Ubuntu, make sure you meet the prerequisites, and then follow the installation steps.

Prerequisites

Note

If you use ufw or firewalld to manage firewall settings, be aware that when you expose container ports using Docker, these ports bypass your firewall rules. For more information, refer to Docker and ufw.

OS requirements

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

  • Ubuntu Lunar 23.04
  • Ubuntu Kinetic 22.10
  • Ubuntu Jammy 22.04 (LTS)
  • Ubuntu Focal 20.04 (LTS)

Docker Engine for Ubuntu is compatible with x86_64 (or amd64), armhf, arm64, s390x, and ppc64le (ppc64el) architectures.

Uninstall old versions

Before you can install Docker Engine, you must first make sure that any conflicting packages are uninstalled.

Distro maintainers provide an unofficial distributions of Docker packages in APT. You must uninstall these packages before you can install the official version of Docker Engine.

The unofficial packages to uninstall are:

  • docker.io
  • docker-compose
  • docker-doc
  • podman-docker

Moreover, Docker Engine depends on containerd and runc. Docker Engine bundles these dependencies as one bundle: containerd.io. If you have installed the containerd or runc previously, uninstall them to avoid conflicts with the versions bundled with Docker Engine.

Run the following command to uninstall all conflicting packages:

$ for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done

apt-get might report that you have none of these packages installed.

Images, containers, volumes, and networks stored in /var/lib/docker/ aren't automatically removed when you uninstall Docker. If you want to start with a clean installation, and prefer to clean up any existing data, read the uninstall Docker Engine section.

Installation methods

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

Install using the apt repository {#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

{% assign download-url-base = "https://download.docker.com/linux/ubuntu" %}

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

    $ sudo apt-get update
$ sudo apt-get install ca-certificates curl gnupg

  2. Add Docker's official GPG key:

    $ sudo install -m 0755 -d /etc/apt/keyrings
$ curl -fsSL {{ download-url-base }}/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
$ sudo chmod a+r /etc/apt/keyrings/docker.gpg

  3. Use the following command to set up the repository:

    $ echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] {{ download-url-base }} \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

    Note

    If you use an Ubuntu derivative distro, such as Linux Mint, you may need to use UBUNTU_CODENAME instead of VERSION_CODENAME.

  4. Update the apt package index:

    $ sudo apt-get update

Install Docker Engine

  1. Install Docker Engine, containerd, and Docker Compose.

    • Latest
    • Specific version

    To install the latest version, run:

     $ sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

    To install a specific version of Docker Engine, start by listing the available versions in the repository:

    # List the available versions:
$ apt-cache madison docker-ce | awk '{ print $3 }'

5:24.0.0-1~ubuntu.22.04~jammy
5:23.0.6-1~ubuntu.22.04~jammy
<...>

    Select the desired version and install:

    $ VERSION_STRING=5:24.0.0-1~ubuntu.22.04~jammy
$ sudo apt-get install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin

  2. Verify that the Docker Engine installation is successful by running the hello-world image.

    $ sudo docker run hello-world

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

You have now successfully installed and started Docker Engine.

Upgrade Docker Engine

To upgrade Docker Engine, follow the installation instructions, choosing the new version you want to install.

Install from a package

If you can't use Docker's apt 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 Engine.

  1. Go to [{{ download-url-base }}/dists/]({{ download-url-base }}/dists/){: target="blank" rel="noopener" class="" }.

  2. Select your Ubuntu version in the list.

  3. Go to pool/stable/ and select the applicable architecture (amd64, armhf, arm64, or s390x).

  4. Download the following deb files for the Docker Engine, CLI, containerd, and Docker Compose packages:

    • containerd.io_<version>_<arch>.deb
    • docker-ce_<version>_<arch>.deb
    • docker-ce-cli_<version>_<arch>.deb
    • docker-buildx-plugin_<version>_<arch>.deb
    • docker-compose-plugin_<version>_<arch>.deb

  5. Install the .deb packages. Update the paths in the following example to where you downloaded the Docker packages.

    $ sudo dpkg -i ./containerd.io_<version>_<arch>.deb \
  ./docker-ce_<version>_<arch>.deb \
  ./docker-ce-cli_<version>_<arch>.deb \
  ./docker-buildx-plugin_<version>_<arch>.deb \
  ./docker-compose-plugin_<version>_<arch>.deb

    The Docker daemon starts automatically.

  6. Verify that the Docker Engine installation is successful by running the hello-world image.

    $ sudo service docker start
$ sudo docker run hello-world

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

You have now successfully installed and started Docker Engine.

{% include root-errors.md %}

Upgrade Docker Engine

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

{% include install-script.md %}

Uninstall Docker Engine

  1. Uninstall the Docker Engine, CLI, containerd, and Docker Compose packages:

    $ sudo apt-get purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin docker-ce-rootless-extras

  2. Images, containers, volumes, or custom configuration files on your host aren't automatically removed. To delete all images, containers, and volumes:

    $ sudo rm -rf /var/lib/docker
$ sudo rm -rf /var/lib/containerd

You have to delete any edited configuration files manually.
