Hi,

AFAIK, there is nothing provided by CentOS itself to SIGs.

In CloudSIG, we are using a combination of tools, SoftwareFactory (gerrit/zuul/nodepool), packages metadata database in repo (rdoinfo) and testing tools to automate validation of updates before pushing new tags and the pushing tags itself.

In latest CentOS Dojo we did a presentation about our automation on dependencies management which includes promoting packages from -candidate to -testing and from -testing to -release (note that there are some other automation to build packages and monitor upstream updates which are not required to promote packages over repos). If you are interested in the details you can check the presentation in [1] and the recording of the talk in [2].

Feel free to poke jpena or myself (amoralej) in #centos-devel if you have  any questions.

Best regards,

Alfredo
