Full details: Stable And Deterministic Test NamesExplanation PASS: The new Ginkgo test hierarchy uses stable string literals: Describe("[sig-hypershift][Jira:Hypershift] Karpenter"), Context("[Feature:AutoNode] Karpenter Upgrade"), and It("should upgrade the control plane and drift Karpenter nodes to the new version"). None contains generated names, timestamps, IPs, namespaces, node names, or other run-dependent values. The only dynamic text is a By() progress message for the release image, not the test name. Full details: Test Structure And QualityExplanation The new test has several assertions without meaningful failure messages. For example, Resolution Add meaningful diagnostic messages to every assertion in the new test. Include the HostedCluster or client operation in the setup messages, such as Full details: Topology-Aware Scheduling CompatibilityExplanation PASS: The PR changes only e2e lifecycle configuration and test code.

This currently isn't running in v2-aws, from what I can tell. How will it be enabled later?

What the... you're right, the upgrade test was skipped (but the other ones ran) 🤦♂️
Need to figure out why

Looks like the AWS job in prow needs updated to set the necessary env vars for upgrade testing, we'll need it for this and for the upcoming non-karpenter AWS upgrade jobs. I'll get the change merged and then we can re-run and should see it reflected in this PR

Actually this turned out to be a v2-ism I missed. Needed to translate env vars to the expected key for upgrade image. It won't be needed after #9420 but for now it should start working, let's see....

Now we're getting an upgrade failure, so that's progress.
I got a success locally so I'll need to dig in and see what's going on here, could be flaky
There was a problem hiding this comment.
What's happening is that the latest and previous image we are using is the exact same:
FromImage: registry.build01.ci.openshift.org/ci-op-c3jg74ds/release@sha256:6b24f9f85ad135cb17d6f11aa7558babb14b4b6953ddc72bd4a863fb7a75e295, toImage: registry.build01.ci.openshift.org/ci-op-c3jg74ds/release@sha256:6b24f9f85ad135cb17d6f11aa7558babb14b4b6953ddc72bd4a863fb7a75e295
Hence, there is no drift (since the Node won't upgrade to the same image) even though the test expects drift to happen.
We got around this in the v1 tests because we start from the previous image and make sure the release config actually passes in an n-1 cluster image version:
LatestReleaseImage, which is pretty much guaranteed to have different ignition payload and/or AMI. We can't guarantee this between nightlies in the same y-stream, or z-stream upgrades. I'm assuming we are not using an n-1 previous image here or something?
We are using
previousImage := hc.Spec.Release.Image
but I don't know what version hostedcluster we initially install this cluster at and if that's still controlled from prow config.
There was a problem hiding this comment.
I guess this new config is what's messing it up: https://github.com/openshift/release/blame/2f1fefd0110506098a1c72474f634b3194b2904b/ci-operator/config/openshift/hypershift/openshift-hypershift-main.yaml#L400-L401
We used to not override this at all, and I assume prow defaulted to OCP_IMAGE_PREVIOUS to an n-1 image?
https://github.com/openshift/release/blob/d29329a17401ab699df5a0c7b302d2f2c47dc6a3/ci-operator/config/openshift/hypershift/openshift-hypershift-main.yaml#L197-L201
EDIT: I think I'm wrong, I think this was always the case, but we've just been lucky that the images haven't been exactly the same. Either way, I think we should be testing n-1 upgrades, instead of z-stream upgrades. But I can take that task separately if that makes sense.
