Worked on hardening the Kubernetes authentication workflow in the gardener/cc-utils repository, focusing on reducing token-related authentication failures and improving automation reliability. Addressed issues in the Kubernetes authentication action by implementing robust token extraction using Shell and YAML, ensuring proper JSON path quoting and safe handling of special characters in curl payloads. Enhanced the extraction process by utilizing jq -r to return raw token strings, which prevents JSON-quoted output and streamlines cluster access. These improvements strengthened CI/CD reliability and reduced troubleshooting time, demonstrating a methodical approach to DevOps challenges and a strong command of GitHub Actions and Kubernetes automation.
