Feb 1, 2025February 2025 monthly summary for pagopa/developer-portal focused on delivering a robust, secure, and maintainable chatbot deployment pipeline and reliable reindex workflow. Key outcomes include a self-hosted runner-based CI/CD pipeline for vector index creation using AWS CodeBuild with eliminated explicit IAM credentials, and updates to chatbot environment handling and deployment workflows. The reindex workflow was enhanced with a dynamic chatbot_lambda_name parameter and a reliable Lambda restart to ensure the latest index and configuration after reindex, reducing post-reindex downtime. Fixed critical issues in the reindex pipeline related to website build steps and documentation directory handling, including refactoring GitHub Actions to properly manage Python dependencies and environment variables. Overall, these changes improve deployment reliability, traceability, and developer efficiency, with strong alignment to business value and operational excellence.
