# openSUSE and SUSE Linux Enterprise
|
|
|
|
This page provides instructions for installing and configuring the lastest
|
|
Docker Engine software on openSUSE and SUSE systems.
|
|
|
|
>**Note:** You can also find bleeding edge Docker versions inside of the repositories maintained by the [Virtualization:containers project](https://build.opensuse.org/project/show/Virtualization:containers) on the [Open Build Service](https://build.opensuse.org/). This project delivers also other packages that are related with the Docker ecosystem (for example, Docker Compose).
|
|
|
|
## Prerequisites
|
|
|
|
You must be running a 64 bit architecture.
|
|
|
|
## openSUSE
|
|
|
|
Docker is part of the official openSUSE repositories starting from 13.2. No
|
|
additional repository is required on your system.
|
|
|
|
## SUSE Linux Enterprise
|
|
|
|
Docker is officially supported on SUSE Linux Enterprise 12 and later. You can find the latest supported Docker packages inside the `Container` module. To enable this module, do the following:
|
|
|
|
1. Start YaST, and select *Software > Software Repositories*.
|
|
2. Click *Add* to open the add-on dialog.
|
|
3. Select *Extensions and Module from Registration Server* and click *Next*.
|
|
4. From the list of available extensions and modules, select *Container Module* and click *Next*.
|
|
The containers module and its repositories are added to your system.
|
|
5. If you use Subscription Management Tool, update the list of repositories at the SMT server.
|
|
|
|
Otherwise execute the following command:
|
|
|
|
$ sudo SUSEConnect -p sle-module-containers/12/x86_64 -r ''
|
|
|
|
>**Note:** currently the `-r ''` flag is required to avoid a known limitation of `SUSEConnect`.
|
|
|
|
The [Virtualization:containers project](https://build.opensuse.org/project/show/Virtualization:containers)
|
|
on the [Open Build Service](https://build.opensuse.org/) contains also bleeding
|
|
edge Docker packages for SUSE Linux Enterprise. However these packages are
|
|
**not supported** by SUSE.
|
|
|
|
### Install Docker
|
|
|
|
1. Install the Docker package:
|
|
|
|
$ sudo zypper in docker
|
|
|
|
2. Start the Docker daemon.
|
|
|
|
$ sudo systemctl start docker
|
|
|
|
3. Test the Docker installation.
|
|
|
|
$ sudo docker run hello-world
|
|
|
|
## Configure Docker boot options
|
|
|
|
You can use these steps on openSUSE or SUSE Linux Enterprise. To start the `docker daemon` at boot, set the following:
|
|
|
|
$ sudo systemctl enable docker
|
|
|
|
The `docker` package creates a new group named `docker`. Users, other than
|
|
`root` user, must be part of this group to interact with the
|
|
Docker daemon. You can add users with this command syntax:
|
|
|
|
sudo /usr/sbin/usermod -a -G docker <username>
|
|
|
|
Once you add a user, make sure they relog to pick up these new permissions.
|
|
|
|
## Enable external network access
|
|
|
|
If you want your containers to be able to access the external network, you must
|
|
enable the `net.ipv4.ip_forward` rule. To do this, use YaST.
|
|
|
|
For openSUSE Tumbleweed and later, browse to the **System -> Network Settings -> Routing** menu. For SUSE Linux Enterprise 12 and previous openSUSE versions, browse to **Network Devices -> Network Settings -> Routing** menu (f) and check the *Enable IPv4 Forwarding* box.
|
|
|
|
When networking is handled by the Network Manager, instead of YaST you must edit
|
|
the `/etc/sysconfig/SuSEfirewall2` file needs by hand to ensure the `FW_ROUTE`
|
|
flag is set to `yes` like so:
|
|
|
|
FW_ROUTE="yes"
|
|
|
|
## Custom daemon options
|
|
|
|
If you need to add an HTTP Proxy, set a different directory or partition for the
|
|
Docker runtime files, or make other customizations, read the systemd article to
|
|
learn how to [customize your systemd Docker daemon options](../articles/systemd.md).
|
|
|
|
## Uninstallation
|
|
|
|
To uninstall the Docker package:
|
|
|
|
$ sudo zypper rm docker
|
|
|
|
The above command does not remove images, containers, volumes, or user created
|
|
configuration files on your host. If you wish to delete all images, containers,
|
|
and volumes run the following command:
|
|
|
|
$ rm -rf /var/lib/docker
|
|
|
|
You must delete the user created configuration files manually.
|
|
|
|
## Where to go from here
|
|
|
|
You can find more details about Docker on openSUSE or SUSE Linux Enterprise in the
|
|
[Docker quick start guide](https://www.suse.com/documentation/sles-12/dockerquick/data/dockerquick.html)
|
|
on the SUSE website. The document targets SUSE Linux Enterprise, but its contents apply also to openSUSE.
