kubernetes: Get events across multiple objects

4 min read

The most commonly used way to get events is by using kubectl describe on each object like this:

$ kubectl describe pod pet2cattle-6597f8464d-hgxpp
Name:         pet2cattle-6597f8464d-hgxpp
(...)
Events:
  Type     Reason     Age    From               Message
  ----     ------     ----   ----               -------

  Normal   Created    3m41s  kubelet            Created container pet2cattle-indexer
  Normal   Started    3m40s  kubelet            Started container pet2cattle-indexer
  Normal   Pulled     3m32s  kubelet            Container image "172.18.1.46:5000/p2c:3.44" already present on machine
  Normal   Created    3m32s  kubelet            Created container pet2cattle
  Normal   Started    3m31s  kubelet            Started container pet2cattle
  Warning  Unhealthy  3m26s  kubelet            Liveness probe failed: Get http://10.42.0.8:8000/: net/http: request canceled (Client.Timeout exceeded while awaiting headers)

It's quite convenient when we are looking for events related to a given but becomes a pain if we need to see how the events are triggered on multiple objects.

From pet to cattle

Treat your kubernetes clusters like cattle, not pets
