📝 WalkthroughWalkthroughThe PR adds a build-tagged Karpenter AWS E2E suite. It covers provisioning, ARM64 nodes, instance profiles, metadata, capacity reservations, subnets, kubelet settings, AutoNode lifecycle, billing, and consolidation. It adds dedicated lifecycle and environment configuration, a kubelet checker pod, and AWS IAM permissions. Shared E2E utilities now support Sequence Diagram(s)sequenceDiagram

Merge Risk: 🟡 Moderate · up to The new ordered e2e suite can leave AutoNode disabled when a scenario aborts, causing later tests to skip or fail for the wrong reason. Merge should wait for deferred state restoration or explicit owner acceptance of this bounded test-isolation risk. Important Pre-merge checks failedPlease resolve all errors before merging.

- Around line 67-76: Update the checker pod’s volume configuration to remove the
broad read-only host-root mount and define separate read-only hostPath volumes
for kubelet.conf and node-sizing-enabled.env, mounting only those files at the
paths consumed by the checker. Retain privileged: true only when required for
OpenShift host-file access, and document that justification; otherwise remove it
and enforce restrictive container security settings.
- Around line 20-28: The check function currently searches the entire file with
an unescaped regular expression, allowing values from the wrong YAML section to
pass. Update the checks around check() and its kubelet field call sites to
validate each expected value within its required kubeReserved or systemReserved
section, using fixed-string matching or exact YAML field-path assertions so
fields such as memory.available are matched literally.

Might be my ignorance, but I thought the Feature label was only to loosely group actual "features", e.g., KarpenterCapacityReservations or KarpenterStaticCapacity or something. Has the definition changed, or maybe I have a wrong assumption.

Good q, I think you know more than me about it right now... I had a question the other day that's related which is whether this feature is actually "AutoNode" in the abstract (that's what we expose in the API), and Karpenter is a currently supported implementation of "AutoNode"
I could definitely use help figuring out the right labels to apply here, these are currently auto-generated
There was a problem hiding this comment.
I think what we call AutoNode (an openshift specific product name) is technically a supported implemention of the upstream Karpenter project, at least that's my interpretation of it, maybe the BU has different opinions.
Anyways, I think all the feature tags would all just fall under [Feature:AutoNode].
We are about to support the feature for ARO in the next few release cycles. Do we need to also label the platform here? I was looking at this: https://hypershift.pages.dev/how-to/ci/v2-testing/test-flow/#labels
Currently we this feature is supported for ROSA and self-managed HCP on AWS.

Updated the labels. Re: ARO I guess we'll need to revisit all this in a followup to enable Azure support and remove any AWS assumptions

Well, I can coordinate with you later on that. Currently Azure support doesn't exist, so I don't want to jump the gun. Just trying to prepare for the future, and I can get your review on any e2e changes when that happens, if that makes sense to you.

We didn't port over a lot of the helpful context comments from the previous tests. Can we do so?
If it's not trivial to do so and hard to figure out which ones are actually useful, I can help with a followup PR if needed.

I noticed this one, but (and this may not be obvious without reading that v2 flow doc I mentioned) it actually doesn't apply anymore because in v2 all the tests are serialized. When we switch to OTE these ordering requirements will actually need eliminated somehow so that the tests are fully isolated. Performance is going to be worse in the meantime as a result if these were running in parallel before. Open to ideas on how to improve it...
There was a problem hiding this comment.
I should clarify, the tests are serialized within a given test group per guest cluster, so there is a degree of parallelism, but at the group-within-a-cluster granularity
There was a problem hiding this comment.
However ordering is still enforced and so I should probably carry over comments that speak to current ordering requirements, I think what got brought over for that is pretty vague in comparison to the original

We've had to refactor the old v1 tests once before because the serialized tests were taking way too long (85+ minutes) (which is what became of why we had to parallelize within the single test).

I'm worried we will have to do something again like this?

I restored these comments up into test registration in a way I hope makes sense, I think there are probably other test level comments which Claude stripped out during the original port. I'll do another pass to see what else should be preserved

Disclaimer: I wasn't involved in the v2 framework design, and have limited knowledge of the decision making around parallelism and scale concerns along those lines.
When I did the (reverse engineered) v2 design doc Devan had a lot of nuanced thoughts on the topic from OCP testing experience which are worth reading and I think apply.
For comparison, the Azure v2 tests which are considered the benchmark/reference for full v2 coverage, clock in at like 1.25 hours and uses 6 clusters including a dedicated autoscaling cluster. Adding these AutoNode tests brings the current single-cluster minimal AWS v2 tests up from 30 seconds (lol) to 50 minutes out of the gate, so to maintain performance parity with the Azure tests we're already at the point where we need to start considering spinning up new hosted clusters to take on test load (e.g. forthcoming nodepool tests, upgrades, etc.)
All that to say I share your concern and we'll have to deal with it one way or another. My current understanding is the serialized-within-a-cluster approach is in service of prioritizing stability within a given cluster and the idea will be to scale up through additional hostedclusters. But we'll definitely need to have that discussion soon as a team, the decision making framework for how to balance these things is somewhat defined but not to the right level of clarity or in terms of specific wall clock budgets, etc.
For now, I think these tests are going to be the last substantial ones we can enable before we start adding more hostedclusters, at least... which is fine AFAICT

There's these types of comments scattered across the old v1 tests, not just the one about parallelism that I think would be useful that don't exist in the v2. Do you want to me to mark all the ones I think should be migrated over, or maybe they should all be moved and anything that doesn't make sense can be removed later.

I wrote #9292 (comment) before I saw this comment, I think you're right there are lots of useful comments which should probably be brought over (and possibly recontextualized) in the migrated code. Tomorrow I'll go through and audit everything that was lost, any feedback you have on particular comments and where they might belong appreciated

I've gone line by line restoring log messages, comments, and fixing other subtle bugs. I also restored the v1 tests based on our offline GA status discussion, which will also make it easier to analyze for diffs within this branch

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Poll the baseline billing metric instead of reading it once.
getVCPUsMetric scrapes the operator pod over the network and returns found=false on any transport error or missing metric family. Line 1643 fails the spec on the first miss. Every other billing assertion in this test polls (waitForBillingMetricVCPUs). Make the baseline read consistent so a transient scrape error does not fail the spec.

Nice work porting these — the suite reads well and the "why" comments (capacity-reservation sizing, ConsolidateAfter drift race, kubelet overflow field) are genuinely useful. A few things worth a look, none blocking given this is a first pass:
- The biggest one is the shared
CreateArgschange: it flips the existing non-informingpubliccluster to PublicAndPrivate + AutoNode, not just the new karpenter variant. Flagged inline. - The billing/consolidation test's teardown behavior is never asserted (inline), plus a few smaller consistency/terminology/error-handling nits.

There was a problem hiding this comment.
CreateArgs() has no per-variant branching, and buildCreateArgs appends it to every ClusterSpec (cmd/create-guests/main.go:283), so the pre-existing public cluster now gets --auto-node and --endpoint-access=PublicAndPrivate too — not just the new karpenter variant. That public group is non-informing (!lifecycle || hosted-cluster-aws), so every existing AWS v2 test now gates CI against a PublicAndPrivate + AutoNode topology it never ran under before (it was --public-only). Anything that assumed public-only or AutoNode-disabled could break or quietly change meaning, and it adds cost/latency across that whole suite.
Can we make CreateArgs variant-aware — keep public on --public-only and apply --auto-node/--endpoint-access only to karpenter? If the shared topology is intentional, the public variant name is now misleading (it's PublicAndPrivate).
There was a problem hiding this comment.
agree with the problem, but would it be more consistent with the framework to add the variant specific create arguments to the cluster spec itself:
return []ClusterSpec{
{
Variant: "public",
ExtraArgs: extraArgs,
},
// <snip>
{
Variant: "karpenter",
ExtraArgs: append(extraArgs, []string{
// Enables Karpenter-based node provisioning (AutoNode)
"--auto-node",
// Required for karpenter to reach the guest API server from the mgmt cluster
"--endpoint-access=PublicAndPrivate",
}...),
},
}as an aside it makes me wonder why we even need CreateArgs in the interface since every variant can declare the full set of arguments needed to create it...

I implemented my own proposal here and lifted --public-only to the public variant. Later we can revisit the discussion about the need for CreateArgs itself

This creates the blocking PDB and ends — no DeferCleanup and no assertion on the force-termination-on-teardown behavior the comment (and the dedicated-cluster note in lifecycle/aws.go) says this cluster exists to exercise. As written, a regression in teardown force-termination wouldn't fail this test; it'd only surface as a disconnected cluster-destroy timeout.
I realize aws.go already notes that v2 tests can't own lifecycle assertions — could we turn that into a tracked framework-gap issue and reference it here, so the intent is captured rather than resting on an unobservable teardown?

getVCPUsMetric drops the error from GetMetricsFromPod and returns (0, false), so a transient fetch failure looks identical to a legitimately-absent metric. waitForBillingMetricVCPUs polls so it tolerates that, but the single-shot call at line 1642 feeds Expect(found).To(BeTrue(), "billing metric should exist...") — a connection blip there would fail with a message that misdescribes the cause. Consider surfacing the error (return or log it) and/or polling that baseline read.

The description fix helps, but the name RUN_KARPENTER_TESTS still reads like it gates whether the Karpenter tests run at all, when its only effect is lowering the min version from 4.23 to 4.22. Someone wiring CI from the var name alone would likely get it wrong. Could we rename it (e.g. KARPENTER_ALLOW_422) to reflect what it does?

Not without changing all the existing CI machinery, this is meant to be a drop in parallel port for now. Agree it should be changed in a followup

Just a few comments, but everything else looks good to me, pending Christoph's review.
As a followup, should #9234 target both v1 and v2? And what will the graduation criteria be for removing v1?
Also since this is informing and a port (no flakes solved in this PR), will there be followup work to reduce flakes?

I'm not sure how you're tracking the azure work but this kind of thing would be good to make a note of somewhere for the porting effort, even if it's just a comment on a jira for now or something. I could add comments here but I'm hesitant to keep churning through the CI builds at the moment, crazy that adding a comment will trigger e2es but that's where we are
