Feb 1, 2026February 2026 — NVIDIA/doca-platform monthly review focusing on security hardening, reboot reliability, and CI efficiency. Delivered Kamaji security hardening (stricter kube-apiserver/kubelet configs with audit logging and admission control plugins), fixed DPUNode reboot condition handling (remove reboot-in-progress when no DPUs exist and improve error handling during node effects/reboots), and streamlined the test suite by removing a redundant Kamaji control plane ExtraArgs test. These changes reduce security risk, improve node stability during reboots, and accelerate CI feedback and maintenance. Overall, the month demonstrates strong capabilities in Kubernetes/Kamaji configuration, distributed node management, and test automation with direct business value in security, reliability, and delivery velocity.
