Is it possible to get the details of the node where the pod ran before restart?

I'm running a kubernetes cluster of 20+ nodes. And one pod in a namespace got restarted. The pod got killed due to OOM with exit code 137 and restarted again as expected. But would like to know the node in which the pod was running earlier. Any place we could check the logs for the info? Like tiller, kubelet, kubeproxy etc...

Solution

  • But would like to know the node in which the pod was running earlier.

    If a pod is killed with ExitCode: 137, e.g. when it used more memory than its limit, it will be restarted on the same node - not re-scheduled. For this, check your metrics or container logs.

    But Pods can also be killed due to over-committing a node, see e.g. How to troubleshoot Kubernetes OOM and CPU Throttle.
