Worked on the spectrocloud/cluster-api-provider-aws repository to deliver NAT Gateway IP management for unmanaged networking environments. Developed the updateNatGatewayIPs function in Go, encapsulating the retrieval, updating, and tagging of NAT Gateway IPs to ensure accurate configuration even when network resources fall outside cluster API management. Focused on AWS cloud infrastructure and networking, the approach emphasized idempotent update flows to prevent operational drift and maintain consistency in NAT IP assignments. These changes improved the reliability and traceability of NAT IP handling, aligning with existing architectural patterns and tagging strategies while enhancing automated network management for unmanaged scenarios. No bugs were reported.
