Worked on the carvel-dev/kapp-controller repository to deliver a safer and more flexible package installation update flow. Developed a feature in Go that enables updating an existing PackageInstall to reference a different packageName, addressing a previous limitation where such updates would result in errors. Incorporated explicit user confirmation prompts to prevent unintended changes and reduce misconfigurations during package management operations. Added comprehensive end-to-end testing to validate the new update process and ensure ongoing reliability. Focused on CLI development, package management, and testing, this work improved upgrade and downgrade safety for production clusters by enhancing both reliability and user experience.
