I don't really understand this after reading through the document. Some use a term like "CPU", but some use "core".
I am running Kubernetes in my laptop for testing purpose. My laptop has one CPU (2.2 GHz) and four cores.
If I want to set the CPU request/limit for pod, should the maximum resource that I have be 1000m or 4000m?
What is the difference (CPU vs. core) here in a Kubernetes context?
To remove any guesswork regarding your laptop or any other environment, execute:
kubectl get nodes
...and then this for a particular node:
kubectl describe node <node-name>
Look for cpu under Allocatable (which may have the same value as under 'Capacity').
Take into consideration that
1 CPU = 1000 millicores/millicpu
when setting "fractional" resources.requests.cpu and resources.limits.cpu for containers.
