Huge pages

In OpenShift Container Platform, nodes/hosts must pre-allocate huge pages.

For more information, see Configuring huge pages.

To request hugepages, pods must supply the following within the pod.spec for each container:

resources:
  limits:
    hugepages-2Mi: 100Mi
    memory: "1Gi"
    cpu: "1"
  requests:
    hugepages-2Mi: 100Mi
    memory: "1Gi"
    cpu: "1"
