Exclude channels from spacewalk-repo-sync and or mgr-sync-refresh-default

Short description

Need possibilities to exclude certain channels from repo-sync when using spacewalk-repo-sync

Details

Several customers would like to have the capability to exclude certain channels/repos from daily repo-sync from the internet.
Often cases some channels/repos can't be synced anymore but still exist and needed in Uyuni/SUMA for downstream client systems. The daily repo-sync job fails at those channels and send notifications which are annoying for the admins.

Suggestions - custom solution:

Tested on SUMA 5.0.1

https://github.com/bjin01/salt-sap-patching/blob/master/spacewalk-repo-sync.py
I added this feature into the spacewalk-repo-sync.py and uploaded it into my github repo.

It reads in a hard-coded config file exclude_channels = '/etc/rhn/spacewalk-repo-sync/exclude.list' in yaml.

exclude_channels:
  - channel1
  - channel2
  - xxx

The list in dictionary key "exclude_channels" will be removed from the dictionary d_ch_repo_sync which is used in original spacewalk-repo-sync.py.
