PROFILE
Katyanna Moura
Over ten months, this developer enhanced the zalando-incubator/kubernetes-on-aws repository by delivering nine features and addressing critical configuration bugs. Their work focused on Kubernetes infrastructure, including implementing managed AWS EFS CSI driver addons, upgrading networking components, and refining RBAC admission controls. They improved security and maintainability by aligning IAM role naming, expanding end-to-end test coverage, and clarifying documentation for authorization flows. Using Go, YAML, and Python, they introduced configurable memory management for EBS CSI controllers and enabled conditional deployment of IAM controllers. Their approach emphasized code quality, operational flexibility, and clear documentation, supporting safer rollouts and streamlined maintenance workflows.

Jun 1, 2026June 2026 monthly summary for zalando-incubator/kubernetes-on-aws: Delivered two major capabilities that enhance operational flexibility and reduce risk in decommissioning. EBS CSI Memory Management Enhancements introduce a configurable memory model for the EBS CSI controller, replacing fixed 40Mi requests/limits with a template-driven setting (ebs_csi_controller_sidecar_memory) and moving memory limits to a dedicated config for dynamic adjustment. Kubernetes IAM Controller Conditional Enablement adds a kube_aws_iam_controller_enabled flag to enable opt-in deployment, with wrapped deployment, RBAC, VPA, and admission controls, enabling safer phased decommissioning. Updated end-to-end tests to support the new enablement path and environment initialization. Overall impact: improved cluster-level memory tuning, safer decommissioning workflows, and enhanced test coverage. Technologies/skills demonstrated include Kubernetes, EBS CSI, config-driven memory management, feature flags, RBAC/VPA integration, and test automation.

Jan 1, 2026Month 2026-01: Focused on delivering a polished EKS Addon for EFS CSI driver in kubernetes-on-aws, driving security, governance, and operational efficiency. Implemented seamless Elastic File System integration via a dedicated addon, tightened IAM role permissions for the CSI driver, consolidated PodIdentityAssociation into the addon, and removed the standalone ServiceAccount manifest since EKS now manages EFS resources. This simplification reduces configuration complexity and improves alignment with AWS-managed resources, enabling faster provisioning and safer upgrade paths.
