|
To get started with Docker on SUSE Linux Enterprise Server (SLES), make sure you
|
|
[meet the prerequisites](#prerequisites), then
|
|
[install Docker](#install-docker).
|
|
|
|
## Prerequisites
|
|
|
|
### Docker EE URL
|
|
|
|
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](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](https://www.docker.com/enterprise-edition/){: target="_blank" class="_" }.
|
|
|
|
Docker Community Edition (Docker CE) is not supported on SLES.
|
|
|
|
### OS requirements
|
|
|
|
To install Docker, you need the 64-bit version of SLES 12.x.
|
|
|
|
### Uninstall old versions
|
|
|
|
Older versions of Docker were called `docker` or `docker-engine`. If these are
|
|
installed, uninstall them, along with associated dependencies.
|
|
|
|
```bash
|
|
$ sudo zypper rm docker docker-engine
|
|
```
|
|
|
|
If removal of the `docker-engine` package fails, use the following command
|
|
instead:
|
|
|
|
```bash
|
|
$ 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`.
|
|
|
|
## 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. 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 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
|
|
|
|
1. Use the following command to set up the **stable** repository, using the
|
|
Docker EE repository URL you located in the [prerequisites](#prerequisites).
|
|
|
|
```bash
|
|
$ sudo zypper addrepo \
|
|
<DOCKER-EE-URL>/12.3/x86_64/stable-{{ minor-version }} \
|
|
docker-ee-stable
|
|
```
|
|
|
|
2. Import the GPG key from the repository.
|
|
|
|
```bash
|
|
$ sudo rpm --import <DOCKER-EE-URL/gpg
|
|
```
|
|
|
|
#### Install Docker EE
|
|
|
|
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
|
|
`77FE DA13 1A83 1D29 A418 D3E8 99E5 FF2E 7668 2BC9` and if so, accept the
|
|
key.
|
|
|
|
2. Install the latest version of Docker EE, or go to the next step to install a
|
|
specific version.
|
|
|
|
```bash
|
|
$ sudo zypper install docker-ee
|
|
```
|
|
|
|
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-ee
|
|
|
|

|
|
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 (`-`):
|
|
|
|
```bash
|
|
$ sudo zypper install docker-ee-<VERSION_STRING>
|
|
```
|
|
|
|
Start Docker:
|
|
|
|
```bash
|
|
$ sudo service docker start
|
|
```
|
|
|
|
4. Verify that Docker EE 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 EE is installed and running. You need to use `sudo` to run Docker
|
|
commands. Continue to [Linux postinstall](linux-postinstall.md) to configure the
|
|
graph storage driver, allow non-privileged users to run Docker commands, and for
|
|
other optional configuration steps.
|
|
|
|
#### Upgrade Docker EE
|
|
|
|
To upgrade Docker EE, 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 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.
|
|
|
|
1. 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.
|
|
|
|
2. Import Docker's official GPG key:
|
|
|
|
```bash
|
|
$ sudo rpm --import <DOCKER-EE-URL>/gpg
|
|
```
|
|
|
|
3. Install Docker EE, changing the path below to the path where you downloaded
|
|
the Docker package.
|
|
|
|
```bash
|
|
$ sudo zypper install /path/to/package.rpm
|
|
```
|
|
|
|
Start Docker:
|
|
|
|
```bash
|
|
$ sudo service docker start
|
|
```
|
|
|
|
4. Verify that Docker EE 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 EE 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 EE
|
|
|
|
To upgrade Docker EE, 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. Uninstall the Docker EE package using the following command.
|
|
|
|
```bash
|
|
$ sudo zypper rm docker-ee
|
|
```
|
|
|
|
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)
|
|
|
