Kube Client Errors

KubeClientErrors #

Meaning #

Kubernetes API server client is experiencing over 1% error rate in the last 15 minutes.

Impact #

Specific kubernetes client may malfunction. Service degradation.

Diagnosis #

Usual issues:

  • networking errors
  • too low resources to perform given API calls (usually too low CPU/memory requests)
  • wrong api client (old libraries)
  • investigate if the app does not request more data than it really requires from kubernetes API, for example it has too wide permissions and scans for resources in all namespaces.

Check logs from client side (sometimes app logs).
