Channels are a method of grouping software packages. In Uyuni channels are divided into base channels, and child channels. Organizing channels in this way ensures that only compatible packages are installed on each system.
A base channel consists of packages built for a specific operating system type, version, and architecture.
For example, all of the packages in SUSE Linux Enterprise Server 12 for the
x86_64 architecture make up a base channel.
The list of packages in SUSE Linux Enterprise Server 12 for the
s390x architecture make up a different base channel.
A system must be subscribed to only one base channel assigned automatically during registration based on the SUSE Linux Enterprise release and system architecture.
For paid channels provided by a vendor, you must have an associated subscription.
A child channel is associated with a specific base channel and provides only packages that are compatible with that base channel.
A system can be subscribed to multiple child channels of its base channel.
When a system has been assigned to a base channel, it is only possible for that system to install the related child channels.
For example, if a system has been assigned to the SUSE Linux Enterprise Server 12
x86_64 base channel, they will only be able to install or update packages compatible with SUSE Linux Enterprise Server 12
In the Uyuni Web UI you can browse your available channels by navigating to. You can modify or create new channels by navigating to .
If you require packages that are not provided by the standard Uyuni base channels, you can create custom channels. Uyuni Administrators and Channel Administrators have channel management authority, which gives them the ability to create and manage their own custom channels.
For more on creating custom channels, see the Administration Guide.
