Go pprof in Kubernetes: Remote Profiling & Flame Graphs
Go pprof in Kubernetes: Remote Profiling & Flame Graphs Answer-first: Remote Go pprof profiling in Kubernetes uses secure kubectl port-forwarding, continuous CPU/memory profile collection, and flame graph analysis to identify production goroutine leaks. You’ve instrumented your Go service with net/http/pprof, run go tool pprof locally against the development binary, and spotted the hot path in your flame graph. Then you deploy to Kubernetes and the bottleneck disappears — because the workload profile in Kubernetes differs from local testing (different request mix, connection pool pressure, GC behavior under actual memory pressure, scheduler interference from co-located pods). ...
