Install Docker Engine on SLES |
4 |
To get started with Docker Engine on SLES, make sure you meet the prerequisites, then install Docker.
Note
We currently only provide packages for SLES on s390x (IBM Z). Other architectures are not yet supported for SLES.
To install Docker Engine, you need a maintained version of SLES 15-SP2 or SLES 15-SP3 on s390x (IBM Z). Archived versions aren't supported or tested.
The SCC SUSE
repositories must be enabled.
The OpenSUSE SELinux
repository
must be enabled. This repository is not added by default, and you need to enable
it for the version of SLES you are running. Run the following commands to add it:
$ sles_version="$(. /etc/os-release && echo "${VERSION_ID##*.}")"
$ opensuse_repo="https://download.opensuse.org/repositories/security:SELinux/SLE_15_SP$sles_version/security:SELinux.repo"
$ sudo zypper addrepo $opensuse_repo
The overlay2
storage driver is recommended.
Older versions of Docker were called docker
or docker-engine
. If these are
installed, uninstall them, along with associated dependencies.
$ sudo zypper remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine \
runc
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 Engine package is now called docker-ce
.
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.
-
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.
-
In testing and development environments, some users choose to use automated convenience scripts to install Docker.
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.
{% assign download-url-base = "https://download.docker.com/linux/sles" %}
Set up the stable repository.
$ sudo zypper addrepo {{ download-url-base }}/docker-ce.repo
Optional: Enable the nightly or test repositories.
These repositories are included in the
docker.repo
file above but are disabled by default. You can enable them alongside the stable repository. The following command enables the nightly repository.$ sudo zypper mr -e docker-ce-nightly
To enable the test channel, run the following command:
$ sudo zypper mr -e docker-ce-test
You can disable the nightly or test repository by running the
$ sudo zypper mr -d docker-ce-nightly $ sudo zypper mr -d docker-ce-test
-
Install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:
$ sudo zypper install docker-ce docker-ce-cli containerd.io
If prompted to accept the GPG key, verify that the fingerprint matches
060A 61C5 1B55 8A7F 742B 77AA C52F EB6B 621E 9F35
, and if so, accept it.Got multiple Docker repositories?
If you have multiple Docker repositories enabled, installing or updating without specifying a version in the
zypper install
orzypper update
command always installs the highest possible version, which may not be appropriate for your stability needs.This command installs Docker, but it doesn't start Docker. It also creates a
docker
group, however, it doesn't add any users to the group by default. -
To install a specific version of Docker Engine, list the available versions in the repo, then select and install:
a. List and sort the versions available in your repo. This example sorts results by version number, highest to lowest, and is truncated:
$ sudo zypper search -s --match-exact docker-ce | sort -r v | docker-ce | package | 3:20.10.8-3 | s390x | Docker CE Stable - s390x v | docker-ce | package | 3:20.10.7-3 | s390x | Docker CE Stable - s390x
The list returned depends on which repositories are enabled, and is specific to your version of SLES.
b. Install a specific version by its fully qualified package name, which is the package name (
docker-ce
) plus the version string (fourth column), separated by a hyphen (-
). For example,docker-ce-3:20.10.8
.$ sudo zypper install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io
This command installs Docker, but it doesn't start Docker. It also creates a
docker
group, however, it doesn't add any users to the group by default. -
Start Docker.
$ sudo systemctl start docker
-
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 a message and exits.
This installs and runs Docker Engine. 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.
To upgrade Docker Engine, follow the installation instructions, choosing the new version you want to install.
If you cannot use Docker's repository to install Docker, you can download the
.rpm
file for your release and install it manually. You need to download
a new file each time you want to upgrade Docker Engine.
-
Go to [{{ download-url-base }}/]({{ download-url-base }}/){: target="blank" rel="noopener" class="" } and choose your version of SLES. Then browse to
15/s390x/stable/Packages/
and download the.rpm
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 zypper install /path/to/package.rpm
Docker is installed but not started. The
docker
group is created, but no users are added to the group. -
Start Docker.
$ sudo systemctl start docker
-
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 a message and exits.
This installs and runs Docker Engine. 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 Engine, download the newer package file and repeat the
installation procedure, using zypper -y upgrade
instead of zypper -y install
, and point to the new file.
{% include install-script.md %}
-
Uninstall the Docker Engine, CLI, and Containerd packages:
$ sudo zypper remove 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.
- Continue to Post-installation steps for Linux.
