Jul 1, 2025July 2025 (Month: 2025-07) Monthly summary for cilium/cilium focusing on delivering AKS Egress Gateway capabilities and stabilizing egress policy reconciliation. Key features delivered: - Egress Gateway Enablement in AKS: configured KPR in conformance tests and enabled BPF masquerading in CI; added necessary Helm values to the CI workflow and conformance configuration to support Egress gateway. Major bugs fixed: - Egress policy reconciliation race condition fix: introduced synchronization to ensure egress policy reconciliation completes before assertions (waitForReconciliationRun), reducing test flakiness. Overall impact and accomplishments: - Enabled secure, policy-driven egress from AKS clusters with reliable CI validation, reducing test flakiness and accelerating validation of egress changes. Technologies/skills demonstrated: - Kubernetes and AKS, Cilium egress features, BPF masquerading, Helm, CI workflow automation, conformance testing, and synchronization patterns for test reliability.

Apr 1, 2025April 2025: Implemented end-to-end Kubernetes API server high-availability (HA) testing in CI/CD for the cilium/cilium repo. Delivered a multi-control-plane Kind-based test that enables kube-proxy replacement, restarts API server pods, and validates Cilium agent failover to ensure connectivity and agent health during API server disruptions. Enhanced the HA test workflow to connect to an active API server when deleting pods, providing realistic failover simulation. No standalone bug fixes documented for this period; the focus was on delivering this resilience feature and integrating it into CI/CD. Commits contributing this work: be430a0c132a3b1cc1dbea337cfb4dbc164fc3a5; cbc4fa330510f080453eea85fb6be6b79e5fb72b. Impact: increases reliability of API server + Cilium integration, reduces risk during upgrades and outages, and accelerates confidence for production deployments. Technologies/skills: Kubernetes, Kind, multi-control-plane HA, kube-proxy replacement, Cilium agent, CI/CD workflows, E2E testing, test automation, Git workflows.
