Passing VpcComponent object to Ec2Component in TypeScript?

Question

Certainly, you can pass a `VpcComponent` object to an `Ec2Component` in TypeScript. Below is an example where we first create a VPC using `awsx.ec2.Vpc` and then pass the VPC to `aws.ec2.Instance`, which we are using to represent `Ec2Component`.

First, we start by installing `@pulumi/awsx` using `npm install --save @pulumi/awsx`.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
import * as awsx from "@pulumi/awsx";

// Create a new VPC using awsx.ec2.Vpc
let vpc = new awsx.ec2.Vpc("custom", {
    cidrBlock: "10.0.0.0/16",
    // Enable DNS resolution and DNS hostnames to allow instances to have DNS in Amazon VPC.
    enableDnsSupport: true,
    enableDnsHostnames: true,
});

// Then pass the VPC to the EC2 instance
let instance = new aws.ec2.Instance("instance", {
    ami: "ami-0c55b159cbfafe1f0",
    instanceType: "t2.micro",
    // Attach the instances to our VPC. We use vpc.publicSubnets[0] to attach the instances to the first subnet.
    subnetId: vpc.publicSubnetIds[0],
    keyName: "myKey", // keyName is used for SSH access
});

// Export the instance's public IP and public DNS name to the Pulumi stack's outputs
export let publicIp = instance.publicIp;
export let publicDns = instance.publicDns;
```
In the above program:
1. A new VPC is declared using `awsx.ec2.Vpc`.
2. We then pass this VPC to an `aws.ec2.Instance`, which we use to represent `Ec2Component`.

VPCs are a fundamental piece of cloud infrastructure that enables you to launch AWS resources in a defined virtual network. In our example, we've created a VPC with a specified CIDR block and enabled DNS support and hostnames for the instances within the VPC.

The EC2 instance is then launched within this VPC.

Please adjust the configuration (like AMI, instance type, keyName) to match your environment.
