SIG Autoscaling Karpenter WG Meeting for 2025-09-04
Source: YouTube · Kubernetes · published Sep 4, 2025 · 15:50
The Carpenter DRRA working group discusses implementing a testing infrastructure with a DRA Quark driver to enable local testing without expensive cloud resources, with plans to create a standalone controller for end-to-end testing 1:19-2:13.
Key Takeaways:
• The team is implementing a DRA Quark driver for testing to avoid expensive cloud provider testing 1:19-2:13
• They distinguish between functional tests (testing individual controllers) and end-to-end tests (testing the full system) 3:00-3:25
• They plan to create a mechanism that automatically generates resource slices for nodes to simulate a DRA driver 4:30-4:53
• The initial approach will use a config map with node selectors and resource slice definitions 6:24-7:14
• They're developing an RFC document to outline the architecture and plan to publish it by the end of September 12:42-13:36
The meeting concluded with next steps including creating a work-in-progress PR to explore the testing infrastructure approach.

Okay, welcome. This is the Carpenter DRRA working group for Thursday, September 4th. Um, yeah, let's go ahead and get started. Sounds like this is going to be relatively quick. We don't have too much on our agenda, but yeah, Lima, did you want to get started? >> Um, yeah. So, I saw on Hold on. Sorry, I'm trying to pull up my thing. Um, I saw that link that we talked about last time where it was to work with the DR quark driver. >> Um, so it's just I was looking at it. It's just uh it's just adding the dependency, but it's only for the scale testing for like cluster loader. So I was wondering if we want to get started. I can and I can like start working on this with using that J quark driver in our unit test. Like for example, like with the don't schedule DRA pod, like ignore it. I think in…
