xDSnap: A Lightweight Tool to Debug Envoy and Consul Dataplanes with Confidence
summary
xDSnap is a Go-based open-source tool that captures Envoy config dumps, stats, pod logs and optional TCP dump pcap from Consul dataplanes and packages them as a tarball for debugging. It runs via kubectl ephemeral containers (no clusterwide RBAC changes), ports to Envoy’s xDS API on 19000, and recommends 30s intervals with 60s duration to get multiple snapshots. It includes pinned dependencies, CI checks, and plans for a background agent and automated AI analysis to summarize misconfigurations and xDS update delays. captures Envoy config dumps and pcap no clusterwide RBAC changes
