…netes 5.0

Add optional presubmit tests for cudn-density with 800 and 1000 iterations on 24-node clusters with r5.4xlarge infra nodes.

Assisted-by: Claude

Summary by CodeRabbit

Adds two optional AWS presubmit jobs for OVN-Kubernetes 5.0. The jobs run cudn-density-single-ns with 800 and 1,000 iterations on 24-node clusters. Each job uses r5.4xlarge infrastructure nodes, custom worker instance types, Orion configuration, and the openshift-qe-cudn-density test chain.

Walkthrough

The configuration adds two optional AWS perfscale jobs for single-namespace CUDN density testing. The jobs run 800 or 1,000 iterations on 24-node clusters with custom instance types and 21 additional workers.

Changes

CUDN density perfscale jobs

Layer / File(s)	Summary
AWS CUDN density job definitions ci-operator/config/openshift/ovn-kubernetes/openshift-ovn-kubernetes-release-5.0.yaml	Adds optional single-namespace jobs for 800 and 1,000 iterations. Both jobs configure custom m6a/r5 instances, 21 additional workers, Orion settings, AWS setup and teardown, and the openshift-qe-cudn-density test chain.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟡 Moderate · up to 432fc

The two new presubmit jobs skip the Orion regression step, which can silently omit intended regression coverage. Merge should wait for the setting to be corrected or the workload-only scope to be explicitly accepted, with generated CI artifacts refreshed and validated.

Important

Pre-merge checks failed

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

❌ Failed checks (1 error, 1 inconclusive)

Check name	Status	Explanation	Resolution
No-Sensitive-Data-In-Logs	❌ Error	The added jobs invoke openshift-qe-cudn-density; its set -x script traces ES_PASSWORD and ES_SERVER, so credentials can appear in the new CI logs.	Disable xtrace while reading and exporting Elasticsearch credentials, or redact those values before the test command runs.
Container-Privileges	❓ Inconclusive	The worktree has no diff, so changed manifest content is not yet established.	Provide the pull request diff or base revision so the added jobs can be checked for privileged container settings.

✅ Passed checks (13 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly summarizes the addition of the 800- and 1000-iteration cudn-density-single-ns presubmit tests for OVN-Kubernetes.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
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 changes CI and generated Prow YAML only; the diff adds no Ginkgo It/Describe/Context/When titles, and the new job identifiers are fixed strings.
Test Structure And Quality	✅ Passed	The PR changes only CI YAML and generated Prow job YAML; it adds no Ginkgo test code, so the stated test-quality check is not applicable.
Microshift Test Compatibility	✅ Passed	The diff adds only YAML CI targets and Prow jobs. It adds no Ginkgo It, Describe, Context, or When tests, so this check is not applicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR changes only YAML CI configuration and generated presubmit jobs; it adds no Ginkgo e2e test declarations, so the SNO compatibility check is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	The diff only adds CI test configuration and generated Prow jobs; it adds no deployment, operator, controller, affinity, topology spread, node-role selector, toleration, replica, or PDB constraint.
Ote Binary Stdout Contract	✅ Passed	The PR changes only two YAML files; it adds no process-level code or stdout/logging calls. The referenced CUDN chain and shell step are pre-existing.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The diff adds only YAML CI configuration and generated presubmit jobs; it adds no Ginkgo tests, IPv4 assumptions, or external-connectivity code.
No-Weak-Crypto	✅ Passed	The PR changes only YAML job configuration and generated presubmit definitions; added-line scans found no MD5, SHA1, DES, RC4, Blowfish, ECB, or crypto implementation/comparison.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Both new CUDN jobs disable the Orion regression step.

The shared chain includes openshift-qe-orion-cudn-density, but RUN_ORION: "false" causes that step to exit before it consumes ORION_CONFIG. Set the value to "true" in both jobs unless the intended scope is workload-only. (raw.githubusercontent.com)
