First pass. Doesn't yet replace all idioms yet for conformance with v2 conventions.

Tests are marked informing.

@ironcladlou: This pull request references CNTRLPLANE-3646 which is a valid jira issue.

Details

In response to this:

First pass. Claude-driven mechanical refactor of the v1 test with only minimal changes for v2 compat. Doesn't replace all idioms yet for conformance with v2 conventions like Eventually() and probably some other stuff. ARM64 not yet tested/supported. Upgrade test not yet ported. Tests are labeled informing until stability is proven.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the openshift-eng/jira-lifecycle-plugin repository.

📝 Walkthrough

Walkthrough

Adds a build-tagged Karpenter E2E suite for AWS resource propagation, provisioning, kubelet configuration, AutoNode lifecycle, billing, and consolidation. Updates AWS cluster setup, test selection, environment variables, IAM permissions, and helper interfaces. Adds a kubelet configuration checker pod manifest. Reduces the older Karpenter E2E test to ARM64 provisioning. Updates the private-router connectivity check to use the router container.

Important

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

❌ Failed checks (2 errors, 2 warnings)

Check name Status Explanation Resolution
Container-Privileges ❌ Error The PR's v2 Karpenter checker manifest sets container securityContext.privileged: true, and the added test embeds and creates this pod. Remove privileged: true and redesign the checker with non-privileged access, or use a narrowly scoped approved mechanism.
No-Sensitive-Data-In-Logs ❌ Error The new v2 test logs checker output, while the pod cats /etc/kubernetes/kubelet.conf; this can expose client keys, certificates, tokens, and internal API hostnames. Do not cat kubelet.conf into test logs. Check required fields without printing the file, or redact credential and endpoint fields before logging.
Test Structure And Quality ⚠️ Warning The PR-added suite has many bare assertions, including Expect(err).NotTo(HaveOccurred()) at lines 117, 128, 165, and 174, violating the required diagnostic messages. Add meaningful context to every assertion, especially cluster API, creation, and cleanup failures, such as the failed operation and resource name.
Ipv6 And Disconnected Network Test Compatibility ⚠️ Warning New Ginkgo tests create workloads from quay.io and registry.access.redhat.com, plus a checker Pod from bare alpine; these public pulls have no mirror and can fail in disconnected CI. Use cluster-internal or mirrored images, then run /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-metal-ipi-ovn-ipv6; otherwise add [Skipped:Disconnected].

Check name Status Explanation
Linked Issues check ✅ Passed Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check ✅ Passed Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names ✅ Passed The PR adds 25 Ginkgo titles as static string literals; no title uses generated names, nodes, namespaces, IPs, timestamps, UUIDs, or runtime formatting.
Topology-Aware Scheduling Compatibility ✅ Passed The diff adds no topology, affinity, spread, PDB, or node-role scheduling to production code; the moved pod has none, and test workloads omit maxUnavailable and target Karpenter node labels.

Pass the test context into newEC2Client.

newEC2Client calls awsutil.NewSession with context.Background(). Every call site already holds tc.Context. Accept a context.Context parameter so cancellation and deadlines propagate.

Karpenter tests pass, arm64 skipped as expected, a test failure in EnsureNetworkPoliciesTest was exposed because it has a code path which has never been executed in CI before these changes. The new path made a bad assumption about the private router pod container name, which is now fixed.

generally looks good, I'm glad we are having this test improvement initiative :-)

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

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...

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

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

latest run uses a dedicated cluster for the karpenter tests. For the last commit I did a side by side run by hand through the whole thing to fix stuff and haven't run it through an LLM again yet. Still plenty of little refactors that could be done but I'm hoping this is getting very close to functional parity as-is. Most of the structural changes internally are in handling deferred cleanups.

First pass. Doesn't yet replace all idioms yet for conformance with v2 conventions.
