How CPU works in Kubernetes Pods

kubernetes-cpu.md
  • The spec.containers[].resources.requests.cpu is converted to its core value, which is potentially fractional, and multiplied by 1024. The greater of this number or 2 is used as the value of the --cpu-shares flag in the docker run command.
  • The spec.containers[].resources.limits.cpu is converted to its millicore value and multiplied by 100. The resulting value is the total amount of CPU time in microseconds that a container can use every 100ms. A container cannot use more than its share of CPU time during this interval.
