Over the past few months, the K8s (Kubernetes) Semantic Conventions SIG focused on stabilizing Kubernetes attributes used by OpenTelemetry Collector processors such as k8sattributes and resourcedetection. That work has now paid off: Kubernetes attributes have been promoted to release candidate status. Users can try this new schema via feature gates and provide feedback before the final stable release. Read on to discover how we reached this milestone and what’s on the horizon.

OpenTelemetry's platform is an observability framework, offering insights into distributed tracing, metrics collection, and log management for cloud-native applications. Through documentation, tutorials, and community contributions, OpenTelemetry provides insights into instrumenting applications to monitor performance and troubleshoot issues. Developers and DevOps teams can learn about distributed tracing standards, telemetry data formats, and integration with observability tools to gain visibility into complex distributed systems.

Kubernetes attributes in OpenTelemetry Semantic Conventions have been promoted to release candidate status, following months of work by the K8s SemConv SIG. The effort was driven by alignment with the OpenTelemetry Collector SIG's goal to stabilize the k8sattributes processor, which heavily depends on these conventions. Users can now opt into the new schema via feature gates (processor.k8sattributes.DontEmitV0K8sConventions and processor.k8sattributes.EmitV1K8sConventions) and provide feedback before the final stable release. Next steps include updating the k8sattributes processor to use the release candidate conventions and continuing work on K8s metrics and entities stability.
