How to use the @kubernetes/client-node.V1Pod function in @kubernetes/client-node

async createPod(name: string,
                  image: string,
                  serviceAccount: string,
                  restartPolicy: string,
                  pullPolicy: string,
                  configMapEnvSource: string,
                  namespace: string) {
    const k8sCoreApi = this.kc.makeApiClient(CoreV1Api)
    let pod = new V1Pod()
    pod.metadata = new V1ObjectMeta()
    pod.metadata.name = name
    pod.metadata.labels = { app: name }
    pod.metadata.namespace = namespace
    pod.spec = new V1PodSpec()
    pod.spec.containers
    pod.spec.restartPolicy = restartPolicy
    pod.spec.serviceAccountName = serviceAccount
    let opContainer = new V1Container()
    opContainer.name = name
    opContainer.image = image
    opContainer.imagePullPolicy = pullPolicy
    let envFromSource = new V1EnvFromSource()
    envFromSource.configMapRef = new V1ConfigMapEnvSource()
    envFromSource.configMapRef.name = configMapEnvSource
    opContainer.envFrom = [envFromSource]

function newRunnerPod(
  podname: string,
  brigadeImage: string,
  imageForcePull: boolean,
  serviceAccount: string,
  resourceRequests: jobs.JobResourceRequest,
  resourceLimits: jobs.JobResourceLimit,

  pod.metadata.name = podname;
  pod.metadata.labels = {

  let c1 = new kubernetes.V1Container();

  c1.image = brigadeImage;

  if (jobShell == "") {
