Get Docker CE for Debian 4

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

Prerequisites

Docker EE customers

Docker EE is not supported on Debian. For a list of supported operating systems and distributions for different Docker editions, see Docker variants.

OS requirements

To install Docker CE, you need the 64-bit version of one of these Debian or Raspbian versions:

  • Buster 10 (Docker CE 17.11 Edge only)
  • Stretch 9 (stable) / Raspbian Stretch
  • Jessie 8 (LTS) / Raspbian Jessie
  • Wheezy 7.7 (LTS)

Docker CE is supported on both x86_64 (or amd64) and armhf architectures for Jessie and Stretch.

Uninstall old versions

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

$ sudo apt-get remove docker docker-engine docker.io

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. The Docker CE package is now called docker-ce.

Extra steps for Wheezy 7.7

  • You need at least version 3.10 of the Linux kernel. Debian Wheezy ships with version 3.2, so you may need to update the kernel{: target="blank" class="" }. To check your kernel version:

    $ uname -r

  • Enable the backports repository. See the Debian documentation{: target="blank" class""}.

Install Docker CE

You can install Docker CE 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, except for Raspbian.

  • 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. This is currently the only approach for Raspbian.

Install using the repository

Before you install Docker CE 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.

Raspbian users cannot use this method!

For Raspbian, installing using the repository is not yet supported. You must instead use the convenience script.

Set up the repository

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

  1. Update the apt package index:

    $ sudo apt-get update

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

    • Jessie or newer
    • Wheezy or older
    $ sudo apt-get install \
     apt-transport-https \
     ca-certificates \
     curl \
     gnupg2 \
     software-properties-common

    $ sudo apt-get install \
     apt-transport-https \
     ca-certificates \
     curl \
     python-software-properties

  3. Add Docker's official GPG key:

    $ curl -fsSL {{ download-url-base}}/gpg | sudo apt-key add -

    Verify that you now have the key with the fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.

    $ sudo apt-key fingerprint 0EBFCD88

pub   4096R/0EBFCD88 2017-02-22
      Key fingerprint = 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid                  Docker Release (CE deb) <docker@docker.com>
sub   4096R/F273FCD8 2017-02-22

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

    Note: The lsb_release -cs sub-command below returns the name of your Debian distribution, such as jessie.

    To also add the edge repository, add edge after stable on the last line of the command.

    • x86_64 / amd64
    • armhf
    $ sudo add-apt-repository \
   "deb [arch=amd64] {{ download-url-base }} \
   $(lsb_release -cs) \
   stable"

    $ echo "deb [arch=armhf] {{ download-url-base }} \
     $(lsb_release -cs) stable" | \
    sudo tee /etc/apt/sources.list.d/docker.list

  5. Wheezy only: The version of add-apt-repository on Wheezy adds a deb-src repository that does not exist. You need to comment out this repository or running apt-get update fails. Edit /etc/apt/sources.list. Find the line like the following, and comment it out or remove it:

    deb-src [arch=amd64] https://download.docker.com/linux/debian wheezy stable

    Save and exit the file.

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

    Learn about stable and edge channels.

Install Docker CE

Note: This procedure works for Debian on x86_64 / amd64, Debian ARM, or Raspbian.

  1. Update the apt package index.

    $ sudo apt-get update

  2. Install the latest version of Docker CE, or go to the next step to install a specific version:

    $ sudo apt-get install docker-ce

    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.

  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:

    $ apt-cache madison docker-ce

docker-ce | {{ site.docker_ce_stable_version }}.0~ce-0~debian | https://download.docker.com/linux/debian jessie/stable amd64 Packages

    b. Install a specific version by its fully qualified package name, which is the package name (docker-ce) plus the version string (2nd column) up to the first hyphen, separated by a an equals sign (=), for example, docker-ce=18.03.0.ce.

    $ sudo apt-get install docker-ce=<VERSION_STRING>

    The Docker daemon starts automatically.

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

    x86_64:

    $ sudo docker run hello-world

    armhf:

    $ sudo docker run armhf/hello-world

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

Docker CE 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. For Raspbian, you can optionally install Docker Compose for Raspbian.

Upgrade Docker CE

To upgrade Docker CE, 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 CE, 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.

  1. Go to {{ download-url-base }}/dists/, choose your Debian version, browse to pool/stable/, choose either amd64 or armhf, and download the .deb file for the Docker CE version you want to install.

    Note: To install an edge package, change the word stable in the URL to edge. Learn about stable and edge channels.

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

    $ sudo dpkg -i /path/to/package.deb

    The Docker daemon starts automatically.

  3. Verify that Docker CE is installed correctly 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 an informational message and exits.

Docker CE 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. For Raspbian, you can optionally install Docker Compose for Raspbian.

Upgrade Docker CE

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

{% include install-script.md %}

Install Docker Compose for Raspbian

You can install Docker Compose using pip:

$ sudo pip install docker-compose

Hypriot{: target="blank" class="" } provides a static binary of docker-compose for Raspbian. It may not always be up to date, but if space is at a premium, you may find it useful. To use it, first follow Hypriot's instructions for setting up the repository{: target="blank" class="" }, then run the following command:

sudo apt-get install docker-compose

Uninstall Docker CE

  1. Uninstall the Docker CE package:

    $ sudo apt-get purge docker-ce

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

    $ sudo rm -rf /var/lib/docker

You must delete any edited configuration files manually.
