The Kubeshark Workflow That Doesn't Stop at the Dashboard

Speedscale’s new Observability surface in proxymock web is designed to close the gap between traces or logs and the actual request and response data exchanged by Kubernetes workloads. It uses the Speedscale operator to deploy nettap, an eBPF-based DaemonSet that captures and decodes network traffic at the kernel level, sends it through an in-cluster forwarder, and automatically port-forwards the stream to a local proxymock web interface at localhost:7788. After installing the operator with Helm, annotating selected workloads for capture, installing and configuring proxymock against the appropriate Kubernetes context, developers can inspect live HTTP, gRPC, database, messaging, and TLS-unwrapped traffic without sidecars, certificate management, application changes, or restarts. Captured request-response pairs can be filtered, saved locally, replayed against a development branch to identify behavioral or latency differences, or used to create mocks for offline dependency testing. The approach is positioned as an alternative to tracing-only tools and as an extension of Kubernetes traffic inspection tools by combining eBPF visibility with local replay, mocking, regression testing, and potential CI integration.
