Apr 1, 2026April 2026 monthly summary for keboola/keboola-as-code focusing on E2B webhook integration efforts and maintenance changes. Key outcomes: - Improved reliability and security for E2B webhook processing via a reverse proxy forwarding design to the keboola-operator, with standardized routes, enhanced error handling, and token management. - Cleaned up feature area by deprecating and removing the E2B webhook forwarding feature and its API from apps-proxy, reducing maintenance surface and aligning with the new design direction. Impact: - Delivered a robust, standards-aligned webhook path that minimizes failure modes and improves traceability. - Reduced ongoing maintenance burden by removing obsolete code paths and OpenAPI definitions while preserving essential capabilities. - Improved observability and error handling in webhook delivery, enabling faster issue diagnosis.

Mar 1, 2026March 2026 — keboola/keboola-as-code: Delivered secure E2B access token management for Kubernetes deployments with Secret-based retrieval, lazy loading, and consolidated AppInfo token handling to reduce redundancy and improve performance. Implemented robust error handling for secret loading and header cleanup when tokens are not configured. Refactored AppInfo to accept context and unify upstream URL/token retrieval, improving maintainability and observability. Overall impact: improved security, lower latency, and more reliable Kubernetes-based deployments.

Jan 1, 2026January 2026 monthly summary for keboola-as-code. Delivered Default Encryption for Project Operations to enforces encryption by default and aligns secret validation with encryption status, ensuring project data remains encrypted unless explicitly disabled. This work was accompanied by a focused commit that fixed the validation and encryption gating logic, reducing edge cases where unencrypted data could pass validation. Overall, the changes strengthen the security posture, improve compliance with data protection requirements, and simplify ongoing secret management.
