How to use the @kubernetes/client-node.V1PodSpec function in @kubernetes/client-node

let resourceRequirements = new kubernetes.V1ResourceRequirements();
  if (resourceRequests) {
    resourceRequirements.requests = {
      cpu: resourceRequests.cpu,
      memory: resourceRequests.memory
    };
  }
  if (resourceLimits) {
    resourceRequirements.limits = {
      cpu: resourceLimits.cpu,
      memory: resourceLimits.memory
    };
  }

  pod.spec.containers = [c1];
  pod.spec.restartPolicy = "Never";
  pod.spec.serviceAccount = serviceAccount;
  pod.spec.serviceAccountName = serviceAccount;
  return pod;
}
