Worked on maintaining cloud infrastructure by delivering a targeted update to the OctopusDeploy/Calamari repository, focusing on Terraform-based Kubernetes cluster configurations. Addressed the deprecation of Kubernetes version 1.28 by upgrading two Azure Kubernetes Service clusters to version 1.29, ensuring continued compatibility with current Kubernetes releases and reducing the risk of deployment pipeline failures. The update was implemented through precise changes to Terraform configuration files, accompanied by clear documentation for future maintainers. Leveraged expertise in DevOps, Kubernetes, and Terraform to improve maintainability and streamline future upgrade processes, demonstrating a methodical approach to infrastructure management and proactive risk mitigation in cloud environments.
