{% assign minor-version = "17.03" %}
To get started with Docker on SUSE Linux Enterprise Server (SLES), make sure you meet the prerequisites, then install Docker.
To install Docker Enterprise Edition (Docker EE), you need to know the Docker EE repository URL associated with your trial or subscription. To get this information:
- Go to https://store.docker.com/?overlay=subscriptions.
- Choose Get Details / Setup Instructions within the Docker Enterprise Edition for SUSE Linux Enterprise Server section.
- Copy the URL from the field labeled Copy and paste this URL to download your Edition.
Use this URL when you see the placeholder text <DOCKER-EE-URL>
.
To learn more about Docker EE, see Docker Enterprise Edition{: target="blank" class="" }.
Docker Community Edition (Docker CE) is not supported on SLES.
To install Docker, you need the 64-bit version of SLES 12.x.
Older versions of Docker were called docker
or docker-engine
. If these are
installed, uninstall them, along with associated dependencies.
$ sudo zypper rm docker docker-engine
If removal of the docker-engine
package fails, use the following command
instead:
$ sudo rpm -e docker-engine
It's OK if zypper
reports that none of these packages are installed.
The contents of /var/lib/docker/
, including images, containers, volumes, and
networks, are preserved. The Docker EE package is now called docker-ee
.
You can install Docker 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.
-
Some users download the RPM 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.
Before you install Docker 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.
-
Use the following command to set up the stable repository, using the Docker EE repository URL you located in the prerequisites.
$ sudo zypper addrepo \ <DOCKER-EE-URL>/12.3/x86_64/stable-{{ minor-version }} \ docker-ee-stable
-
Import the GPG key from the repository.
$ sudo rpm --import <DOCKER-EE-URL/gpg
-
Update the
zypper
package index.$ sudo zypper refresh
If this is the first time you have refreshed the package index since adding the Docker repositories, you will be prompted to accept the GPG key, and the key's fingerprint will be shown. Verify that the fingerprint matches
77FE DA13 1A83 1D29 A418 D3E8 99E5 FF2E 7668 2BC9
and if so, accept the key. -
Install the latest version of Docker EE, or go to the next step to install a specific version.
$ sudo zypper install docker-ee
Start Docker:
$ sudo service docker start
-
On production systems, you should install a specific version of Docker instead of always using the latest. List the available versions. The following example only lists binary packages and is truncated. To also list source packages, omit the
-t package
flag from the command.$ zypper search -s --match-exact -t package docker-ee Loading repository data... Reading installed packages... S | Name | Type | Version | Arch | Repository --+---------------+---------+---------------------------------------+--------+--------------- | docker-ee | package | {{ minor-version }}-1 | x86_64 | docker-ee-stable
The contents of the list depend upon which repositories you have enabled. Choose a specific version to install. The third column is the version string. The fifth 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 a hyphen (
-
):$ sudo zypper install docker-ee-<VERSION_STRING>
Start Docker:
$ sudo service docker start
-
Verify that Docker EE 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 EE is installed and running. You need to use sudo
to run Docker
commands. Continue to Linux postinstall to configure the
graph storage driver, allow non-privileged users to run Docker commands, and for
other optional configuration steps.
To upgrade Docker EE, first run sudo zypper refresh
, then follow the
installation instructions, choosing the new version you want
to install.
If you cannot use the official Docker repository to install Docker, you can
download the .rpm
file for your release and install it manually. You will
need to download a new file each time you want to upgrade Docker.
-
Go to the Docker EE repository URL associated with your trial or subscription in your browser. Go to
12.3/x86_64/stable-{{ minor-version }}
and download the.rpm
file for the Docker version you want to install. -
Import Docker's official GPG key:
$ sudo rpm --import <DOCKER-EE-URL>/gpg
-
Install Docker EE, changing the path below to the path where you downloaded the Docker package.
$ sudo zypper install /path/to/package.rpm
Start Docker:
$ sudo service docker start
-
Verify that Docker EE 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 EE is installed and running. 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.
To upgrade Docker EE, download the newer package file and repeat the
installation procedure, using zypper update
instead of zypper install
, and pointing to the new file.
-
Uninstall the Docker EE package using the following command.
$ sudo zypper rm docker-ee
-
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.

Continue to Post-installation steps for Linux
