Runzhen Wang developed a self-managed AKS cost export tool in the Azure/AKS repository, enabling daily CSV reporting of AKS cluster costs by integrating Azure Cost Management with AKS Cost Analysis. The solution was implemented in Go and Shell, leveraging Docker for deployment and Kubernetes for orchestration. Runzhen created automated deployment scripts and comprehensive Markdown documentation to support configuration and usage, ensuring the tool was CI-friendly and easy to onboard. The work included repository management tasks such as removing redundant files, which streamlined ongoing maintenance. This feature improved cost visibility for AKS clusters, supporting better budgeting, forecasting, and governance processes.
