Assigning Pods to Specific Nodes

https://docs.openshift.com/container-platform/3.6/dev_guide/deployments/basic_deployment_operations.html#assigning-pods-to-specific-nodes

Assigning a Pod to Nodes that Match a Node Selector

Edit the DeploymentConfig that defines the pod:

oc edit dc/<pod-name>

Inject the node selector specification under

spec:
  ...
  template:
    ...
    spec:
      ...
      nodeSelector:
        keyA: valueA

Restart the corresponding pod, by simply deleting it.
