Exploring the Depths: Distributed Tracing with OpenTelemetry on ClusterAPI - GCP
summary
Integrates OpenTelemetry into Cluster API for GCP (CAPG) using Go and kubebuilder to add tracing spans across nested controller logic running on GKE, backing a 12-week mentorship prototype. Traces export to Jaeger and Google Cloud Trace, replacing slow log-only debugging with end-to-end request visibility, timing of individual reconcilers and functions, and async GCP API call correlation. Prototype works and demonstrates a viable path to reduce toil for CAPG developers.
