Why does Runtime.getRuntime.availableProcessors() always return 1 in OpenShift?

Solution Unverified - Updated -

Issue

  • Why does Runtime.getRuntime.availableProcessors() always return 1 in OpenShift, if both resources.requests.cpu and resources.limits.cpu is unset.
  • If there is no cpu resource setting in the pod, I expect it to return the number of CPUs in the worker host.

Environment

  • OpenJDK
    • OpenJDK 1.8.191+
    • 11
    • -XX:+UseContainerSupport
  • OpenShift
    • 3.11
