To verify that everything has worked as expected:
|
||||
|
||||
$ sudo docker run --rm -i -t ubuntu /bin/bash
|
||||
$ 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"
|
||||
|
||||
This should download and import the `ubuntu` image, and then start `bash` in a container. To exit the container type `exit`.

**Done!**
