May 2026 – OpenShift Release: Delivered enhanced performance testing observability and artifact collection, expanded cudn-density workloads, and improved test reliability, delivering measurable business value through better observability and scalable test automation. Key features include robust artifact collection for performance tests (pprof data and metrics) even when tests fail, and a new cudn-density workload step registry with AWS 4.22 periodic jobs. The work extends perf-testing coverage across cluster-density-v2, node-density, node-density-cni, node-density-heavy, and udn-density-pods. These enhancements were implemented via two commits (071a7eea668290fcd2775cec267088fc7df89176 and 5aa2b544e41bd6d2248ad1386033b787e2b0aa64), demonstrating strong capabilities in observability, automation, and scalable test orchestration. Technologies demonstrated include kube-burner integration, pprof/metrics pipelines, Bash scripting resilience around exit handling, and step-registry design for workload automation.

April 2026 Monthly Summary for performance and reliability improvements across core OpenShift test automation. Key features delivered: - kube-burner/kube-burner-ocp: Added cudn-density workload for CUDN scale testing. This workload stress-tests OVN-Kubernetes networking with ClusterUserDefinedNetworks (CUDNs) by creating grouped namespaces sharing a primary CUDN, deploying a 3-tier microservice, and exercising network policies, egress firewalls, and service load balancing across the CUDN. Notable technical deliverables include a custom cudnLatency metric, cross-namespace readiness probes with ring topology, per-namespace NetworkPolicies, Layer2/Layer3 CUDN topology support, DaemonSet-based pre-allocation, and robust GC cleanup handling CUDN finalizers. - openshift/release: Orion Deferred Summary Reporting Enhancement. Implemented a deferred summary report step to consolidate regression reporting, improved handling of JSON results, and addressed storage limitations by fetching deferred Orion JSONs from GCS rather than SHARED_DIR. Major bugs fixed: - Resolved shellcheck warnings and ci-operator issues in Orion reporting flow. - Fixed storage and artifact handling by migrating deferred Orion JSONs fetch to GCS, avoiding Kubernetes Secret SHARED_DIR size limits. Overall impact and accomplishments: - Expanded test coverage for complex CUDN networking scenarios, enabling earlier detection of regressions in OVN-Kubernetes networking, with measurable improvements in test telemetry and readiness verification. - Strengthened regression reporting reliability for Orion, reducing artifact storage constraints and improving end-to-end visibility of failures. Technologies/skills demonstrated: - Kubernetes, OVN-Kubernetes, CUDN, cross-namespace networking, network policies, and topology design (Layer2/Layer3). - Test automation design (cudn-density workload, readiness probes, GC cleanup), E2E testing with BATS, and telemetry metrics. - CI/CD hygiene and scripting (ShellCheck fixes, ci-operator stabilization). - Cloud artifact management (GCS integration) for robust regression results delivery. Business value: - Faster, more reliable detection of networking regressions; reduced risk in deployment pipelines; improved visibility into test results and regression trends; better utilization of cloud storage for artifact management.
