{ "response": "Take a breath—intermittent 502s after a deploy are common and almost always traceable without anything being fundamentally 'broken'. I need three quick answers: What do the Node container logs and any reverse-proxy/error logs show in the exact windows when 502s occur? How is the app exposed (compose/K8s ports, network mode, healthcheck) and does it stay Up or show restarts? What do host and container resource metrics (CPU, memory, disk, file descriptors) look like during failures? Meanwhile follow this safe triage: 1) Run docker ps -a and note status/restarts/uptime for the API container. 2) Capture timestamped logs with docker logs --since 30m and check reverse-proxy logs if present. 3) docker exec into the container and confirm the Node process is listening and responds on its internal port (curl localhost). 4) Watch docker stats and host free/df/ulimit while reproducing or waiting for the next 502. 5) Diff the new image/compose against the last known-good deploy for port, env, resource-limit or dependency changes. Correlated 502 timestamps with container restarts, OOM events, or upstream connection refusals in the logs would confirm the likely cause.", "diagnostic_questions": [ "What do the Node container logs and any reverse-proxy/error logs show in the exact windows when 502s occur?", "How is the app exposed (compose ports, network mode, healthcheck) and does the container stay Up or show restarts?", "What do host and container resource metrics (CPU, memory, disk, file descriptors) look like during failures?" ], "triage_steps": [ "Run docker ps -a and note status, restart count, and uptime for the API container", "Capture timestamped logs: docker logs --since 30m plus any reverse-proxy error logs", "docker exec into the container and verify the Node process is listening and answers on its internal port", "Monitor docker stats together with host free -h, df -h and ulimit -n while waiting for or reproducing a 502", "Diff the new image/compose/Dockerfile against the last known-good deploy for port, env, limit or dependency changes" ], "likely_evidence_needed": "Correlated 502 timestamps with container restarts, OOM events, or upstream connection refusals in the logs would confirm the likely cause." }
