title: Get Docker for OpenSUSE and SLES
|
|
---
|
|
|
|
To get started with Docker on OpenSUSE or SLES, make sure you
|
|
[meet the prerequisites](#prerequisites), then
|
|
[install Docker](#install-docker).
|
|
|
|
## Prerequisites
|
|
|
|
### OS requirements
|
|
|
|
To install Docker, you need the 64-bit version one of the following:
|
|
|
|
- OpenSuSE Leap 42.x
|
|
- SLES 12.x
|
|
|
|
### Remove unofficial Docker packages
|
|
|
|
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:
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
## Install Docker
|
|
|
|
You can install Docker 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 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out of date.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.
|
|
|
|
### Install using the repository
|
|
|
|
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.
|
|
|
|
#### Set up the repository
|
|
|
|
1. Use the following command to set up the **stable** repository:
|
|
|
|
```bash
|
|
$ sudo zypper addrepo \
|
|
https://yum.dockerproject.org/repo/main/opensuse/13.2/ \
|
|
docker-main
|
|
```
|
|
|
|
2. **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` or
|
|
> `zypper update` command will always install the highest possible version,
|
|
> which will almost certainly be an unstable one.
|
|
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
```bash
|
|
$ sudo zypper removerepo docker-testing
|
|
```
|
|
|
|
#### Install Docker
|
|
|
|
1. Update the `zypper` package index.
|
|
|
|
```bash
|
|
$ 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.
|
|
|
|
2. Install the latest version of Docker, or go to the next step to install a
|
|
specific version.
|
|
|
|
```bash
|
|
$ 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` or `zypper 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:
|
|
|
|
```none
|
|
Additional rpm output:
|
|
/var/tmp/rpm-tmp.YGySzA: line 1: fg: no job control
|
|
```
|
|
|
|
Start Docker:
|
|
|
|
```bash
|
|
$ sudo service docker start
|
|
```
|
|
|
|
3. 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.
|
|
|
|
```bash
|
|
$ zypper search -s --match-exact -t package docker-engine
|
|
|
|
Loading repository data...
|
|
Reading installed packages...
|
|
|
|
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 (`-`):
|
|
|
|
```bash
|
|
$ 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:
|
|
|
|
```none
|
|
Additional rpm output:
|
|
/var/tmp/rpm-tmp.YGySzA: line 1: fg: no job control
|
|
```
|
|
|
|
Start Docker:
|
|
|
|
```bash
|
|
$ sudo service docker start
|
|
```
|
|
|
|
4. Verify that `docker` 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 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
|
|
|
|
To upgrade Docker, first run `sudo zypper refresh`, then follow the
|
|
[installation instructions](#install-docker), choosing the new version you want
|
|
to install.
|
|
|
|
### Install from a package
|
|
|
|
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.
|
|
|
|
1. Go to [https://yum.dockerproject.org/repo/main/opensuse/13.2/Packages/](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 to `testing`. Do not use unstable versions of Docker in production
|
|
> or for non-testing workloads.
|
|
|
|
2. Install Docker, changing the path below to the path where you downloaded
|
|
the Docker package.
|
|
|
|
```bash
|
|
$ 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:
|
|
|
|
```none
|
|
Additional rpm output:
|
|
/var/tmp/rpm-tmp.YGySzA: line 1: fg: no job control
|
|
```
|
|
|
|
Start Docker:
|
|
|
|
```bash
|
|
$ sudo service docker start
|
|
```
|
|
|
|
3. Verify that `docker` 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 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), using `zypper update`
|
|
instead of `zypper install`, and pointing to the new file.
|
|
|
|
## Uninstall Docker
|
|
|
|
1. Uninstallation using `zypper rm` fails. Uninstall the Docker package using
|
|
the following command:
|
|
|
|
```bash
|
|
$ sudo rpm -e --noscripts docker-engine
|
|
```
|
|
|
|
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.
|
|
|
|

|
|
|
|
- Continue to [Post-installation steps for Linux](linux-postinstall.md)
|
|
|
|
- Continue with the [User Guide](../../userguide/index.md).
