Debugging python applications inside k8s environment
summary
Concrete recipes and tools replace platitudes: run a debug server with debugpy + DAP, build images with an entrypoint toggle and baked git SHA, and attach from VS Code via port‑forwarding or from-cluster using kubectl debug ephemeral container. Alternatives: telnet into a pdbclone or use PUDB inside a debug sidecar. Remember to scale replicas to one, forward both app and debug ports, and use K9s for quick pod ops — these steps let a live k8s Python process be inspected and controlled rather than guessed at.
