title: Kubernetes apply nodeSelector via command
body: <p>Is there a way to apply a <a href="https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#nodeselector" rel="nofollow noreferrer">nodeSelector</a> via command? (like <code>kubectl apply</code>)</p>
  <p>It would be nice if it is applicable on running deployments or namespaces, otherwise applying to running pods is also fine.</p>
  <p>Any tips are appreciated</p>
