Worked on enhancing the reliability of the Update Images Action in the duplocloud/actions repository by introducing robust dependency validation and error handling. Implemented shell scripting to check for the presence of jq and duploctl before proceeding with image updates, ensuring that all prerequisites are met and reducing the risk of pipeline failures. Leveraged GitHub Actions and CI/CD best practices to enable fail-fast behavior, so the script exits immediately on error, preventing unsafe deployments. Updated the action.yml configuration to document these new requirements, resulting in safer and more predictable image update workflows within the continuous integration environment.
