Install Docker Engine on Debian | 4 |
To get started with Docker Engine on Debian, 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 Debian or Raspbian versions:
- Debian Buster 10 (stable)
- Debian Stretch 9 / Raspbian Stretch
Docker Engine is supported on x86_64
(or amd64
), armhf
, and arm64
architectures.
Uninstall old versions
Older versions of Docker were called docker
, docker.io
, or docker-engine
.
If these are installed, uninstall them:
$ sudo apt-get remove docker docker-engine docker.io containerd runc
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 Engine package is now called docker-ce
.
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, 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 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.
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" %}
-
Update the
apt
package index and install packages to allowapt
to use a repository over HTTPS:$ sudo apt-get update $ sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ gnupg-agent \ software-properties-common
-
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
-
Use the following command to set up the stable repository. To add the nightly or test repository, add the word
nightly
ortest
(or both) after the wordstable
in the commands below. Learn about nightly and test channels.Note: The
lsb_release -cs
sub-command below returns the name of your Debian distribution, such ashelium
. Sometimes, in a distribution like BunsenLabs Linux, you might need to change$(lsb_release -cs)
to your parent Debian distribution. For example, if you are usingBunsenLabs Linux Helium
, you could usestretch
. Docker does not offer any guarantees on untested and unsupported Debian distributions.- x86_64 / amd64
- armhf
- arm64
$ sudo add-apt-repository \ "deb [arch=amd64] {{ download-url-base }} \ $(lsb_release -cs) \ stable"
$ sudo add-apt-repository \ "deb [arch=armhf] {{ download-url-base }} \ $(lsb_release -cs) \ stable"
$ sudo add-apt-repository \ "deb [arch=arm64] {{ download-url-base }} \ $(lsb_release -cs) \ stable"
Install Docker Engine
Note: This procedure works for Debian on
x86_64
/amd64
, Debian ARM, or Raspbian.
-
Update the
apt
package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:$ sudo apt-get update $ sudo apt-get install docker-ce docker-ce-cli containerd.io
Got multiple Docker repositories?
If you have multiple Docker repositories enabled, installing or 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. -
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:
$ apt-cache madison docker-ce docker-ce | 5:18.09.1~3-0~debian-stretch | {{ download-url-base }} stretch/stable amd64 Packages docker-ce | 5:18.09.0~3-0~debian-stretch | {{ download-url-base }} stretch/stable amd64 Packages docker-ce | 18.06.1~ce~3-0~debian | {{ download-url-base }} stretch/stable amd64 Packages docker-ce | 18.06.0~ce~3-0~debian | {{ download-url-base }} stretch/stable amd64 Packages ...
b. Install a specific version using the version string from the second column, for example,
5:18.09.1~3-0~debian-stretch
.$ sudo apt-get install docker-ce=<VERSION_STRING> docker-ce-cli=<VERSION_STRING> containerd.io
-
Verify that Docker Engine 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 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 [
{{ download-url-base }}/dists/
]({{ download-url-base }}/dists/){: target="blank" rel="noopener" class="" }, choose your Debian version, then browse topool/stable/
, chooseamd64
,armhf
, orarm64
and download the.deb
file for the Docker version you want to install.Note: To install a nightly or test (pre-release) package, change the word
stable
in the above URL tonightly
ortest
. Learn about nightly and test channels. -
Install Docker Engine, 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.
-
Verify that Docker Engine 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 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.
{% include install-script.md %}
Uninstall Docker Engine
-
Uninstall the Docker Engine, CLI, and Containerd packages:
$ sudo apt-get purge docker-ce docker-ce-cli containerd.io
-
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 $ sudo rm -rf /var/lib/containerd
You must delete any edited configuration files manually.
