openSUSE
Docker is available in openSUSE 12.3 and later. Please note that due to its current limitations Docker is able to run only 64 bit architecture.
Docker is not part of the official repositories of openSUSE 12.3 and
openSUSE 13.1. Hence it is neccessary to add the Virtualization
repository from
OBS to install the docker package.
Execute one of the following commands to add the Virtualization repository:
# openSUSE 12.3
$ sudo zypper ar -f http://download.opensuse.org/repositories/Virtualization/openSUSE_12.3/ Virtualization
# openSUSE 13.1
$ sudo zypper ar -f http://download.opensuse.org/repositories/Virtualization/openSUSE_13.1/ Virtualization
No extra repository is required for openSUSE 13.2 and later.
SUSE Linux Enterprise
Docker is available in SUSE Linux Enterprise 12 and later. Please note that due to its current limitations Docker is able to run only on 64 bit architecture.
Installation
Install the Docker package.
$ sudo zypper in docker
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 /usr/sbin/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!
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 our systemd article to learn how to customize your systemd Docker daemon options.
