title: Deployment with replicaset & node shutdown
body: <p>We have a deployment with replicas: 1
  We deploy it in a 3 agent node k8s cluster (k8s 1.8.13) and it gets deployed to a node (say agent node-0). When I shutdown node-0, the rs does not get rescheduled (its been more than an hour now).
  I have checked that the selector labels are correct and we have plenty of capacity in the cluster (and also we don’t specify resource requests). Also I checked that our node selectors are just checking for agent nodes and there are 2 other agent nodes available.
  Is there any special treatments around this shutdown scenario that k8s does ?</p>
