我应该向Pulumi参数传递什么类类型才能使其工作？

class VirtualMachineConfig {
  size: pulumi.Input<string>;
  os: pulumi.Input<string>;
  diskSize: pulumi.Input<number>;

  constructor(size: pulumi.Input<string>, os: pulumi.Input<string>, diskSize: pulumi.Input<number>) {
    this.size = size;
    this.os = os;
    this.diskSize = diskSize;
  }
}

const vmConfig = new VirtualMachineConfig("Standard_D2s_v3", "Ubuntu", 50);

const vm = new azure.compute.VirtualMachine("my-vm", {
  resourceGroupName: "my-group",
  location: "eastus",
  vmSize: vmConfig.size,
  osProfile: {
    computerName: "my-vm",
    adminUsername: "adminuser",
    adminPassword: "password123",
    customData: ""
  },
  storageImageReference: {
    publisher: "Canonical",
    offer: "UbuntuServer",
    sku: "16.04-LTS",
    version: "latest"
  },
  storageOsDisk: {
    createOption: "FromImage",
    managedDiskType: "Standard_LRS",
    diskSizeGb: vmConfig.diskSize
  },
  osProfileLinuxConfig: {
    disablePasswordAuthentication: true
  },
});

export const vmId = vm.id;
