Worked on moby/buildkit to enhance observability and reliability by implementing build completion metrics and integrating OpenTelemetry for detailed build lifecycle telemetry. Used Go to instrument the llbsolver component, exposing Prometheus-compatible metrics with stable labels and a design that prevents cardinality issues. Threaded a dedicated MeterProvider throughout the codebase, avoiding reliance on the global OTEL provider and enabling per-package observability. Synchronized vendor dependencies to ensure reproducible builds and maintain security standards. These changes provided actionable latency and failure-rate data, improved incident response, and established a foundation for future metrics and operator documentation to support ongoing operations readiness.

May 1, 2026May 2026 monthly summary for moby/buildkit focused on delivering observability and reliability improvements that directly support faster incident response and more data-driven performance tuning. Delivered Build Completion Metrics and OpenTelemetry integration to expose build lifecycle telemetry and prepared the system for scalable metrics collection. Key accomplishments include: - Implemented metrics for build completion in llbsolver and updated OpenTelemetry dependencies to enable observability and access to latest features. - Exposed three Prometheus-ready instruments to monitor build events with stable labels and an architecture that avoids cardinality blow-up: buildkit.builds (counter; labels: status, error_code), buildkit.builds.steps (counter; labels: kind), and buildkit.build.duration (Base2 exponential histogram; labels: status). - Ensured metrics are forward-compatible and do not rely on the global OTEL provider by threading a dedicated MeterProvider through the codebase. - Performed vendor dependency synchronization to maintain reproducible builds and align with security and performance updates. Business impact and accomplishments: - Significantly improved observability into build pipelines, enabling faster triage of failed builds and better SLA tracking. - Reduced risk of metric cardinality issues while providing actionable latency and failure-rate data for operators and developers. - Laid groundwork for additional metrics (e.g., worker count, cache state) and operator documentation to support operations readiness. Technologies/skills demonstrated: - OpenTelemetry integration, Prometheus metric types (counter, histogram), and label design for reliable observability. - MeterProvider usage (avoiding global providers) and llbsolver instrumentation. - Dependency management and vendor sync for reproducible builds.
