openSUSE
Docker is available in openSUSE 12.3 and later. Please note that due to the current Docker limitations Docker is able to run only on the 64 bit architecture.
Installation
The docker package from the Virtualization
project on
OBS provides Docker on openSUSE.
To proceed with Docker installation please add the right Virtualization repository.
# openSUSE 12.3
$ sudo zypper ar -f http://download.opensuse.org/repositories/Virtualization/openSUSE_12.3/ Virtualization
$ sudo rpm --import http://download.opensuse.org/repositories/Virtualization/openSUSE_12.3/repodata/repomd.xml.key
# openSUSE 13.1
$ sudo zypper ar -f http://download.opensuse.org/repositories/Virtualization/openSUSE_13.1/ Virtualization
$ sudo rpm --import http://download.opensuse.org/repositories/Virtualization/openSUSE_13.1/repodata/repomd.xml.key
Install the Docker package.
$ sudo zypper in docker
It's also possible to install Docker using openSUSE's1-click install. Just visit this page, select your openSUSE version and click on the installation link. This will add the right repository to your system and it will also install the docker package.
Now that it's installed, let's start the Docker daemon.
$ sudo systemctl start docker
If we want Docker to start at boot, we should also:
$ sudo systemctl enable docker
The docker package creates a new group named docker. Users, other than root user, need to be part of this group in order to interact with the Docker daemon. You can add users with:
$ sudo usermod -a -G docker <username>
To verify that everything has worked as expected:
$ sudo docker run --rm -i -t opensuse /bin/bash
This should download and import the opensuse image, and then start bash in
a container. To exit the container type exit.
If you want your containers to be able to access the external network you must
enable the net.ipv4.ip_forward rule.
This can be done using YaST by browsing to the
Network Devices -> Network Settings -> Routing menu and ensuring that the
Enable IPv4 Forwarding box is checked.
This option cannot be changed when networking is handled by the Network Manager.
In such cases the /etc/sysconfig/SuSEfirewall2 file needs to be edited by
hand to ensure the FW_ROUTE flag is set to yes like so:
FW_ROUTE="yes"
Done!
