To get started with Docker on OpenSUSE or SLES, make sure you meet the prerequisites, then install Docker.
To install Docker, you need the 64-bit version one of the following:
OpenSUSE’s operating system repositories contain an older version of Docker,
with the package name docker
instead of docker-engine
. If you installed this
version of Docker on OpenSUSE or on SLES by using the OpenSUSE repositories,
remove it using the following command:
$ sudo zypper rm docker
The contents of /var/lib/docker
are not removed, so any images, containers,
or volumes you created using the older version of Docker are preserved.
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.
Some users cannot use third-party repositories, and must rely on the version of Docker in the OpenSUSE or SLES repositories. This version of Docker may be out of date. Those users should consult the OpenSuSE or SLES documentation and not follow these procedures.
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, update, or downgrade Docker from the repository.
Use the following command to set up the stable repository:
$ sudo zypper addrepo \
https://yum.dockerproject.org/repo/main/opensuse/13.2/ \
docker-main
Optional: Enable the testing repository. You can enable it alongside the stable repository. Do not use unstable repositories on on production systems or for non-testing workloads.
Warning: If you have both stable and unstable repositories enabled, updating without specifying a version in the
zypper install
orzypper update
command will always install the highest possible version, which will almost certainly be an unstable one.
$ sudo zypper addrepo \
https://yum.dockerproject.org/repo/testing/opensuse/13.2/ \
docker-testing
You can disable a repository at any time by running the zypper rmrepo
command. The following command disables the testing
repository.
$ sudo zypper removerepo docker-testing
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
58118E89F3A912897C070ADBF76221572C52609D
and if so, accept the key.
Install the latest version of Docker, or go to the next step to install a specific version.
$ sudo zypper install docker-engine
Warning: If you have both stable and unstable repositories enabled, installing or updating Docker without specifying a version in the
zypper install
orzypper update
command will always install the highest available version, which will almost certainly be an unstable one.
The RPM will install, but you will receive the following error during the post-installation procedure, because Docker cannot start the service automatically:
Additional rpm output:
/var/tmp/rpm-tmp.YGySzA: line 1: fg: no job control
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-engine

S | Name | Type | Version | Arch | Repository
--+---------------+---------+---------------------------------------+--------+---------------
| docker-engine | package | 1.13.0-1 | x86_64 | docker-main
| docker-engine | package | 1.12.6-1 | x86_64 | docker-main
| docker-engine | package | 1.12.5-1 | x86_64 | docker-main
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-engine-<VERSION_STRING>
The RPM will install, but you will receive the following error during the post-installation procedure, because Docker cannot start the service automatically:
Additional rpm output:
/var/tmp/rpm-tmp.YGySzA: line 1: fg: no job control
Start Docker:
$ sudo service docker start
Verify that docker
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 is installed and running. 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.
To upgrade Docker, first run sudo zypper refresh
, then 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 will need to download
a new file each time you want to upgrade Docker.
Go to https://yum.dockerproject.org/repo/main/opensuse/13.2/Packages/
and download the .rpm
file for the Docker version you want to install.
Note: To install a testing version, change the word
main
in the URL totesting
. Do not use unstable versions of Docker in production or for non-testing workloads.
Install Docker, changing the path below to the path where you downloaded the Docker package.
$ sudo yum -y install /path/to/package.rpm
The RPM will install, but you will receive the following error during the post-installation procedure, because Docker cannot start the service automatically:
Additional rpm output:
/var/tmp/rpm-tmp.YGySzA: line 1: fg: no job control
Start Docker:
$ sudo service docker start
Verify that docker
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 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, download the newer package file and repeat the
installation procedure, using zypper update
instead of zypper install
, and pointing to the new file.
Uninstallation using zypper rm
fails. Uninstall the Docker package using
the following command:
$ sudo rpm -e --noscripts docker-engine
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.
