{% assign minor-version = "17.03" %}
To get started with Docker on Debian, make sure you
[meet the prerequisites](#prerequisites), then
[install Docker](#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](/engine/installation/#docker-variants).
### OS requirements
To install Docker, you need the 64-bit version of one of these Debian or
Raspbian versions:
- Stretch (testing)
- Jessie 8.0 (LTS) / Raspbian Jessie
- Wheezy 7.7 (LTS)
Docker CE is supported on both `x86_64` 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:
```bash
$ sudo apt-get remove docker docker-engine
```
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](https://wiki.debian.org/HowToUpgradeKernel){: target="_blank" class="_" }.
To check your kernel version:
```bash
$ uname -r
```
- Enable the `backports` repository. See the
[Debian documentation](https://backports.debian.org/Instructions/){: 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](#install-using-the-repository) and install
from them, for ease of installation and upgrade tasks. This is the
recommended approach.
- 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.
### 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.
#### Set up the repository
{% assign download-url-base = "https://download.docker.com/linux/debian" %}
1. Install packages to allow `apt` to use a repository over HTTPS:
**Jessie or Stretch**:
```bash
$ sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg2 \
software-properties-common
```
**Wheezy**:
```bash
$ sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
python-software-properties
```
2. Add Docker's official GPG key:
```bash
$ curl -fsSL {{ download-url-base}}/gpg | sudo apt-key add -
```
Verify that the key ID is `9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88`.
```bash
$ 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
```
3. Use the following command to set up the **stable** repository. You always
need the **stable** repository, even if you want to install **edge** builds
as well.
> **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.
**amd64**:
```bash
$ sudo add-apt-repository \
"deb [arch=amd64] {{ download-url-base }} \
$(lsb_release -cs) \
stable"
```
**armhf**:
You can choose between two methods for `armhf`. You can use the same method
as Debian, setting up the repository and using `apt-get install`, or you can
use a convenience script, which requires privileged access, but sets up the
repository for you and installs the packages for Bash auto-completion.
- Setting up the repository directly:
```bash
$ echo "deb [arch=armhf] https://apt.dockerproject.org/repo \
raspbian-jessie main" | \
sudo tee /etc/apt/sources.list.d/docker.list
```
- Using the convenience script:
```bash
$ curl -sSL https://get.docker.com > install.sh
$ sudo bash ./install.sh
```
> **Warning**: Always audit scripts downloaded from the internet before
> running them locally.
If you use this method, Docker is installed and starts automatically.
Skip to step 4 below.
4. **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` will fail. Edit `/etc/apt/sources.list`. Find the
line like the following, and comment it out or remove it:
```none
deb-src [arch=amd64] https://download.docker.com/linux/debian wheezy stable
```
Save and exit the file.
[Learn about **stable** and **edge** channels](/engine/installation/).
#### Install Docker CE
> **NOTE**: Docker CE is not available on raspbian-jessie, scroll down to follow the Raspian steps.
1. Update the `apt` package index.
```bash
$ sudo apt-get update
```
2. Install the latest version of Docker, or go to the next step to install a
specific version. Any existing installation of Docker is replaced.
Use this command to install the latest version of Docker:
```bash
$ sudo apt-get install docker-ce
```
> **Warning**: If you have multiple Docker repositories enabled, installing
> or updating without specifying a version in the `apt-get install` or
> `apt-get update` command will always install the highest possible version,
> which may not be appropriate for your stability needs.
3. On production systems, you should install a specific version of Docker
instead of always using the latest. This output is truncated. List the
available versions:
```bash
$ apt-cache madison docker-ce
docker-ce | {{ minor-version }}.0~ce-0~debian-jessie | {{ download-url-base}} jessie/stable amd64 Packages
```
The contents of the list depend upon which repositories are enabled,
and will be specific to your version of Debian (indicated by the `jessie`
suffix on the version, in this example). Choose a specific version to
install. The second column is the version string. The third column is the
repository name, which indicates which repository the package is from and
by extension its stability level. To install a specific version, append the
version string to the package name and separate them by an equals sign (`=`):
```bash
$ 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.
```bash
$ 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. You need to use `sudo` to run Docker
commands. Continue to [Linux postinstall](linux-postinstall.md) to allow
non-privileged users to run Docker commands and for other optional configuration
steps.
#### Upgrade Docker CE
To upgrade Docker, first run `sudo apt-get update`, then follow the
[installation instructions](#install-docker), choosing the new version you want
to install.
### Install on Raspian (Raspberry Pi)
>**Warning**: This isn't necessary if you used the recommended
>```bash $ curl -sSL https://get.docker.com | sh ``` command!
Once you have added the Docker repo to `/etc/apt/sources.list.d/`, you should
see `docker.list` if you:
```bash
$ ls /etc/apt/sources.list.d/
```
And the contents of the `docker.list` should read:
`deb [arch=armhf] https://apt.dockerproject.org/repo raspbian-jessie main`
If you don't see that in `docker.list`, then either comment the line out, or
`rm` the `docker.list` file.
Once you have verified that you have the correct repository, you may continue
installing Docker.
1. Update the `apt` package index.
```bash
$ sudo apt-get update
```
2. Install the latest version of Docker, or go to the next step to install a
specific version. Any existing installation of Docker is replaced.
Use this command to install the latest version of Docker:
```bash
$ sudo apt-get install docker
```
> **NOTE**: By default, Docker on Raspian is Docker Community Edition, so
> there is no need to specify docker-ce.
> **NOTE**: If ```bash $ curl -sSL https://get.docker.com | sh ``` isn't used,
> then docker won't have auto-completion! You'll have to add it manually.
3. Verify that Docker is installed correctly by running the `hello-world`
image.
```bash
$ sudo docker run hypriot/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.
### 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 will need to download
a new file each time you want to upgrade Docker.
1. Go to [{{ download-url-base }}/dists/]({{ download-url-base }}/dists/),
choose your Debian version, browse to `stable/pool/stable/`, choose either
`amd64` or `armhf`,and download the `.deb` file for the Docker version you
want to install and for your version of Debian.
> **Note**: To install an **edge** package, change the word
> `stable` in the URL to `edge`.
> [Learn about **stable** and **edge** channels](/engine/installation/).
2. Install Docker CE, changing the path below to the path where you downloaded
the Docker package.
```bash
$ 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.
```bash
$ 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. You need to use `sudo` to run Docker
commands. Continue to [Post-installation steps for Linux](linux-postinstall.md)
to allow non-privileged users to run Docker commands and for other optional
configuration steps.
#### Upgrade Docker
To upgrade Docker, download the newer package file and repeat the
[installation procedure](#install-from-a-package), pointing to the new file.
## Uninstall Docker
1. Uninstall the Docker package:
```bash
$ 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:
```bash
$ sudo rm -rf /var/lib/docker
```
You must delete any edited configuration files manually.
