February 2026 monthly summary for DataDog/cilium. Delivered a critical bug fix to ensure Cilium-Operator starts reliably when Multicluster Services (MCS) and installCRDs are enabled. The change updates CRD permissions to allow CRD updates during startup, addressing startup failures observed in multi-cluster deployments. This work is captured in commit 3953c12f8b52aa8624a13fe2aa8e8ff68f2c36b2 (helm: allow multicluster-services installCRDs to update CRDs), and aligns Helm logic with CRD lifecycle expectations for MCS scenarios.

March 2025: Focused on stabilizing nodepool scaling in kubernetes/autoscaler by adopting Patch-based updates using MergePatchType. Implemented a bug fix for Cluster API nodepool scaling conflicts, updated tests to cover patch-based operations (clusterapi_controller_test.go and clusterapi_unstructured.go), and aligned the codebase with Kubernetes patch semantics to improve robustness for concurrent updates. These changes reduce scaling-related conflicts, increase reliability in production clusters, and demonstrate strong proficiency with Kubernetes API patching and Go-based test maintenance.
