This tab allows Administrators to create, clone, and delete custom channels. These channels may contain altered versions of distribution-based channels or custom packages.

7.6.3.1. Manage Software Channels ⇒ Channel Details

The default screen of the Manage Software Channels tab is a listing of all available channels. This includes custom, distribution-based, and child channels.

To clone an existing channel, click the clone channels link in the upper right of the screen, select the channel to be cloned from the dropdown menu, and click the Create Channel button. The next screen presents various options for the new channel, including base architecture and GPG options. Make your selections and click the Create Channel button to complete the process.

To create a new channel, click the create new channel link in the upper right of the screen. Select the various options for the new channel, including base architecture and GPG options. Make your selections and click the Create Channel button. Note that a channel created in this manner is blank, containing no packages. You must either upload software packages or add packages from other

channels. You may also choose to include Errata Updates in your custom channel. 7.6.3.1.1. Manage Software Channels ⇒ Channel Details ⇒ Channel Details

This screen lists the selections you made during the channel creation process. This page includes the Globally Subscribable checkbox that permits all users to subscribe to the channel.

7.6.3.1.2. Manage Software Channels ⇒ Channel Details ⇒ Managers

This subtab allows you to select which users may alter or delete this channel. Satellite Administrators and Channel Administrators may alter or delete any channel.

To allow a user to alter the channel, select the checkbox next to the user's name and click the Update button. To allow all users to manage the channel, click the Select All button at the bottom of the list followed by the Update button. To remove a user's ability to manage the channel, uncheck the box next to their name and click the Update button.

7.6.3.1.3. Manage Software Channels ⇒ Channel Details ⇒ Errata

This subtab allows channel managers to list, remove, clone, and add Errata to their custom channel. Custom channels not cloned from a distribution may not add Errata until there are packages in the channel. Only Errata that match the base architecture of the channel and apply to a package in that channel may be added to the channel. Finally, only cloned or custom Errata may be added to custom channels. Errata may be included in a cloned channel if they are selected during channel creation. 7.6.3.1.4 . Manage Software Channels ⇒ Channel Details ⇒ Packages

This subtab is similar to the Errata subtab. It allows Channel and Organization Administrators to list, remove, compare, and add packages to the custom channel.

To list all packages in the channel, click the List / Rem ove Packages link. Check the box to the left of any package you wish to remove, then click the Rem ove Packages button in the lower right of the page.

To add packages, click the Add Packages link. Choose a channel from which to select packages from the drop-down menu and click the View button to continue. Check the box to the left of any package you wish to add to the channel, then click the Add Packages button in the bottom right of the screen. To compare packages within the current channel with those of another channel, select the other channel from the drop-down menu and click the Com pare button. All packages present in either channel are compared, and the results displayed on the next screen. This information includes the architecture and version of each package.

To make the two channels identical, click the Merge Differences button in the lower right. The following screen allows you to select how conflicts are resolved. Click the Preview Merge button to view the results of the merging without making any changes to the channels. Finally, select those packages that you wish to merge and click the Merge Packages button followed by the Confirm button to perform the merge.

7.6.3.2. Manage Software Channels ⇒ Manage Software Packages

This tab allows you to manage custom software packages owned by your organization. You may view a list of all custom software or view only those packages in a selected custom channel. To select the channel whose custom packages you wish to view, select the channel from the drop-down menu and click the View button.

This tab allows you to add and manage existing custom or third-party package repositories as well as link the repositories to an existing channel. The Repositories feature currently supports yum

repositories.

To create a new repository click the Create New Repository link at the top right of the Manage Repositories page. The Create Repository screen prompts you to enter a Repository Label (such as fedora-13-i386) as well as a Repository URL (such as

http://customrepo.example.com). You can also enter URLs pointing to mirror lists as well as direct download URLs. Upon completion, click the Create Repository button.

To link the newly created repository to an existing software channel, click the Manage Software Channels link in the left menu, then click the Channel you want to link. From the channel's Detail page, click the Repositories subtab, then check the box corresponding to the repository you want to link, and click Update Repositories.

To synchronize packages from a custom repository to your channel, click the Sync link from the channel's Repositories subtab, and confirm by clicking the Sync button.

You can also perform a sync via command-line by using the spacewalk-repo-sync command. For example:

spacewalk-repo-sync --channel=<CHANNEL_NAME> --url=<http://FQDN>

For example, to sync the Fedora 13 repository for i386 architecture, enter the following:

spacewalk-repo-sync --channel=fedora-13-i386 --

url=https://mirrors.fedoraproject.org/metalink?repo=updates-released-f13&arch=i386

7.7. Configuration

This tab is the portal to managing your configuration channels and files, whether they are centrally managed or limited to a single system. You must be a Configuration Administrator or an Satellite Administrator to see the Configuration tab. In addition, you must have at least one Provisioning entitlement, or the tab does not appear.

Centrally-managed files are those that are available to multiple systems; changes to a single file in a central configuration channel can affect many systems. In addition, there are local configuration

channels. Each system with a Provisioning entitlement has a local configuration channel (also referred to as an override channel) and a Sandbox channel. Both central and local configuration management are discussed in detail later in this chapter.
