Speaking on this this topic in general, as a Katello developer I find it limiting and frustrating that it is so hard to configure and iterate on our CI service. Using services that I can run locally or on my own instance in my github fork makes it much easier to test out changes and contribute them.
If you want a real example, I’m trying to make this change, which will require CI changes, but I have no idea to go about iterating on the change and making sure an updated directory structure in our CI doesn’t break anything, other than making a best-guess PR.
I do really love the ease-of-use with GH actions, but I realize it may not work for Katello since afaict it doesn’t support centos. However, I do wonder if there are any steps we could take to run a testing environment on ubuntu.
If we stay with Jenkins, I think we should look for a way that changes can be tested by a developer easily either locally or some sort of hosted automation.
I think this is an area we could improve even if we don’t find GH actions doesn’t work for us, it feels quite limited now.
