How to use the @kubernetes/client-node.V1VolumeMount function in @kubernetes/client-node

// If the job needs build-wide storage, enable it.
    if (job.storage.enabled) {
      const vname = "build-storage";
      this.runner.spec.volumes.push({
        name: vname,
        persistentVolumeClaim: { claimName: e.workerID.toLowerCase() }
      } as kubernetes.V1Volume);
      let mnt = volumeMount(vname, job.storage.path);
      this.runner.spec.containers[0].volumeMounts.push(mnt);
    }

    // If the job needs access to a docker daemon, mount in the host's docker socket
    if (job.docker.enabled && project.allowHostMounts) {
      var dockerVol = new kubernetes.V1Volume();
      var dockerMount = new kubernetes.V1VolumeMount();
      var hostPath = new kubernetes.V1HostPathVolumeSource();
      hostPath.path = jobs.dockerSocketMountPath;
      dockerVol.name = jobs.dockerSocketMountName;
      dockerVol.hostPath = hostPath;
      dockerMount.name = jobs.dockerSocketMountName;
      dockerMount.mountPath = jobs.dockerSocketMountPath;
      this.runner.spec.volumes.push(dockerVol);
      for (let i = 0; i < this.runner.spec.containers.length; i++) {
        this.runner.spec.containers[i].volumeMounts.push(dockerMount);
      }
    }

    // If the job defines volumes, add them to the pod's volume list.
    // If the volume type is `hostPath`, first check if the project allows host mounts
    // and throw an error if it it does not.
    for (let v of job.volumes) {

function volumeMount(
  name: string,
  mountPath: string
): kubernetes.V1VolumeMount {
  let v = new kubernetes.V1VolumeMount();
  v.name = name;
  v.mountPath = mountPath;
  return v;
}
