title: Kubernetes resource request relative to node resources
body: <p>HPA needs the pod has resource request defined in order to calculate metrics to know when to schedule new pods.</p>
  <p>Is there a way to specify that the CPU request of a pod is the 75% of the node resources? Like if the machine has 4 cores, it should use <code>cpu: 3</code>, and if the machine has 8 cores, it should use <code>cpu: 6</code>.</p>
  <p>I would like to be able to scale up the node fleet without having to change the kubernetes definitions.</p>
