Debugging at Scale in Production - Deep into Your Containers with Kubectl Debug
summary
Kubernetes now supports ephemeral debug containers via kubectl debug (added in v1.23) so teams attach a full distro to a running pod and inspect files and namespaces without changing the app; open-source KoolKits supplies four curated images (Go, JVM, Node, Python) with debuggers and profilers; remote JDWP debugging requires restarts and is insecure; a LightRun agent injects logpoints, nonblocking snapshots, counters and tagged metrics across thousands of pods, works without restarts, and throttles heavy probes for safety.
