title: Kubernetes: Scheduling Pod without resource limits
body: <p>Kubernetes: what happens when a pod has no resources limits / requests defined?</p>
  
  <p>How much resources can a pod use in Kubernetes (GKE) when it has no (or only partial) resource limits/requests defined?</p>
  
  <p>For example, I have a pod with only memory <em>limits</em> and memory <em>requests</em>, but it has no cpu specs. 
  Will the cpu available to this pod be:</p>
  
  <ul>
  <li>0</li>
  <li>as much as left on the node/namespace (total minus all other pod claims)</li>
  <li>as much as possible regarding <em>actual</em> use by other pods on the node/namespace</li>
  </ul>
