And that the fact that it's "container first" and an internal project first is worrying too.One very important thing to understand here is that Konflux is built on *top* of https://tekton.dev/ which itself is built on top of Kubernetes https://kubernetes.io/ which are well documented and established FOSS projects used by multiple organizations, with a wealth of knowledge and tooling built on top of both of them.
If "Tekton" click for you, it does not click for me. Opening the https://tekton.dev/ provides no more information. Richard asked several questions:
~~~ This doesn't really help with the "what". I work at Red Hat and still have no idea what Konflux actually is. For Koji I can take a look at the web interface: https://koji.fedoraproject.org/koji/ and kind of get the gist of what's going on. Or to be a bit fairer as many here are already familiar with Koji, SUSE's build system web interface: https://build.opensuse.org/ Where's the web interface of Konflux? Where can I explore what it's doing / building right now? ~~~ This can be applied to Tetkon. If I browse to e.g. https://tekton.dev/docs/getting-started/tasks/It immediately suggest to install `minikube` and what not. But I'd likely be just a user.
Even if I go to the Fedora Konflux instance: https://konflux.apps.kfluxfedorap01.toli.p1.openshiftapps.com/application-pipeline/ I can't see anything useful there (except spinner). So can I look at some (useful) UI, is there some CLI or something tangible? Vít
Which is not true of Koji. Just one example: In the past we've hit issues where some RPMs take a lot more CPU/RAM to build than others. In Kubernetes, projects like https://github.com/kubernetes/autoscaler/tree/9f87b78df0f1d6e142234bb32e8acbd71295585a/vertical-pod-autoscaler exist to automatically track and scale the requested resources for pods (containers) based on historical or inferred usage. Because Tekton builds (tasks) are just pods ( https://tekton.dev/docs/pipelines/podtemplates/ ) these techniques work for them. But for Koji, there's no such ecosystem, and only ad-hoc bespoke ways to tell the system how much resources a particular build requires. Strongly related to this is that Koji is a bespoke task manager mostly used to build RPMs, but has little to do with running generic workloads (especially relevant: integration tests running in containers) so we end up with disjoint infrastructure. With Tekton it's way more obvious how to e.g. build a container (or an RPM which is installed into a built container) and then run tests on that container before e.g. promoting it on, within the same cluster or CI job.
