title: Changing pod's labels on the fly
body: <p>I wonder if it is possible to change labels of pods on the fly so services route requests to those pods based on new labels.</p>
  
  <p>For example I have two services A and B. Then I have 10 pods, where 5 have label type = A (matches service A) and the other 5 have label type = B (matches service B). At some point I want to change labels on pods to achieve a configuration of 2 with label type = A and 8 with label type = B.</p>
  
  <p>I want to know if I can just change the labels and services will be updated accordingly without having to stop and start new pods with different labels.</p>
