What this PR does / why we need it:

Enables the ability to run all Karpenter-related tests (and nothing more) for the new e2e-aws-autonode-standalone-ko test being added by openshift/release#84052.

Which issue(s) this PR fixes:

Fixes AUTOSCALE-875

Special notes for your reviewer:

Summary by CodeRabbit

  • New Features
    • Added support for running AWS lifecycle configurations in autonode-only mode.
    • Autonode-only mode limits cluster test coverage to the Karpenter variant.
    • Standard mode continues to support both public and Karpenter variants.
    • Configuration logs now indicate whether autonode-only mode is enabled.

📝 Walkthrough

Walkthrough

NewAWSPlatformConfig reads HYPERSHIFT_AUTONODE_ONLY and stores the result in autonodeOnly. ClusterSpecs returns only the Karpenter specification when the flag is enabled; otherwise, it returns the existing variants. TestMatrix applies the same selection to test groups and reuses the Karpenter group.

Full details: Stable And Deterministic Test Names

Explanation

The pull request changes only test/e2e/v2/lifecycle/aws.go. The committed diff adds no Ginkgo It, Describe, Context, or When title. The new TestGroup.Name, Variant, LabelFilter, and JUnitFile values are fixed strings (karpenter, karpenter, karpenter, and junit_karpenter.xml). The environment flag controls selection only and does not enter a test title.

Full details: Test Structure And Quality

Explanation

PASS: The pull request changes only test/e2e/v2/lifecycle/aws.go. It adds an environment flag and selects existing ClusterSpec and TestGroup values. It does not add or modify Ginkgo It, BeforeEach, AfterEach, Eventually, or Consistently blocks. It introduces no resource creation, waits, or assertions, so none of the stated test-quality failure conditions apply.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS — The pull request changes only test/e2e/v2/lifecycle/aws.go. It adds an environment flag and filters the e2e cluster specifications and test matrix. It does not add or modify deployment manifests, operator code, controllers, anti-affinity, topology spread constraints, replica counts, node selectors, PDBs, or arbiter tolerations. The existing specific test toleration is unchanged. Therefore, this custom check is not triggered.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request changes only test/e2e/v2/lifecycle/aws.go. It adds configuration and test-matrix selection logic, but it does not add Ginkgo declarations or test bodies. The added --endpoint-access=PublicAndPrivate argument is cluster configuration, not evidence of a public internet dependency. No stated IPv4 assumption or external connectivity requirement was introduced.

Full details: No-Weak-Crypto

Explanation

PASS: The pull request changes only test/e2e/v2/lifecycle/aws.go. The added code reads the HYPERSHIFT_AUTONODE_ONLY configuration flag, logs it, and selects cluster specifications and test groups. The diff adds no weak-crypto algorithm, crypto package, custom crypto implementation, or secret/token comparison. The file imports only context, fmt, log, os, strings, time, and the Kubernetes client package.

Full details: Container-Privileges

Explanation

PASS: The pull request changes only test/e2e/v2/lifecycle/aws.go. The added code reads an environment variable, logs it, and selects cluster/test variants. The patch contains no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, root-user, or security-context settings, and changes no Kubernetes manifest.

Full details: No-Sensitive-Data-In-Logs

Explanation

PASS: The only changed log field is autonodeOnly, a boolean derived from whether HYPERSHIFT_AUTONODE_ONLY equals true. The other logged values (region, zones, and a generated expiration-date tag) were already logged before this pull request. No password, token, API key, PII, session ID, hostname, or customer data is newly logged.

Pass HYPERSHIFT_AUTONODE_ONLY to both lifecycle commands.

create-guests and run-tests build AWS configuration in separate processes. If only create-guests receives the flag, the manifest contains only karpenter, while run-tests builds the default matrix and exits with Manifest/test matrix mismatch.

For context, for the test invocation itself, callers of test-e2e-v2 already have --ginkgo.focus and --ginkgo.label-filter. In the context of run-tests those labels are driven by the TestMatrix.

Selective hosted cluster ("guests") creation and test filtering is a common local use case and calling test-e2e-v2 directly does the latter, but there's nothing yet for the former, and nothing that integrates/works in the context of run-tests. If it were more flexible it could serve all the use cases but there could be drawbacks.

  1. Targeted opinionated option I use locally at the moment is an allowed-variants flag to create-guests to filter out cluster specs by variant alias (e.g. to create only the karpenter hostedcluster). Must be used with test-e2e-v2 to run applicable tests against whatever clusters exist, run-tests won't work because the TestMatrix is static and run-tests passthrough of ginkgo args gets complicated very fast
  2. Accept serialized (complete? partial-to-merge?) []ClusterSpec and TestMatrix from the user (maybe as some kind of TestPlan "test API" object); seems like it would cover all the use cases since you could basically define a totally custom test plan (including hostedclusters and the tests to execute within them). The canonical "test plans" could continue living in the Go code but they could presumably come from any source. This seems extremely flexible. Risks are...?

What I'd like to avoid is the proliferation of test-specific flags and modalities and figure out the UX gap which would make them unnecessary

Now that I've written it out, extracting declarative test plan objects out into Prow seems like it could be pretty interesting, I wonder if anyone has already considered it...
