Kubernetes - node capacity

Question

I'm running a small node in gcloud with 2 pods running. Google cloud console shows all resources utilization

<40% cpu utilization

about 8k n\w bytes

about 64 disk bytes.

When adding the next pod, it fails with below error.

FailedScheduling:Failed for reason PodExceedsFreeCPU and possibly others

Based on the numbers I see in google console, ~60% CPU is available. is there anyway to get more logs? Am I missing something obvious here?

Thanks in advance !

Answer 1

As kubernetes reserve some space if more cpu or memory is needed you should check the capacity allocated by the cluster instead of the utilization.

kubectl describe nodes

You can find a deeper description about the capacity of the nodes in: http://kubernetes.io/docs/user-guide/compute-resources/
