Developed a credential persistence feature for the harness/lite-engine repository, enabling automated and secure credential management in CI/CD workflows. The solution creates a .netrc file with OS-specific naming and dynamically generates its content from environment variables, allowing credentials to persist across pipeline runs when the DRONE_PERSIST_CREDS feature flag is enabled. This approach reduces manual credential handling and improves reproducibility for Windows, Linux, and macOS environments. The work involved backend development using Go, with integration of CI/CD best practices and cross-platform file I/O. No major bugs were recorded, and code cleanup was performed to streamline maintenance and ensure long-term reliability.
