Tail logs from multiple Kubernetes pods at once
Apache-2.0
ABOUT
kubectl logs follows one pod, so a rolling Deployment or a multi-container inference service requires many terminals. stern tails matching pods and containers in one stream with timestamps and color, which is the difference between spotting a crash loop and missing it in a replica you were not watching.
INSTALL
brew install sternINTEGRATION GUIDE
1. Follow logs from every replica of a model-serving Deployment during a rollout
2. Filter worker and sidecar containers when debugging a RAG API that spans several pods
3. Watch crash-looping jobs across a namespace without starting a log stack
4. Color-code pod streams while reproducing a flaky training-operator failure
