How to import AWS VPC with Pulumi CLI?

Question

Pulumi · Accepted Answer

You can import an existing VPC into a Pulumi program using the `get` function, provided by Pulumi AWS Provider. This will allow Pulumi to retrieve the state of the existing VPC without needing to manage it.

Here's an example on how you might do this:

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

// Create an AWS provider connection
const provider = new aws.Provider("aws-provider", {
 region: "us-west-2",
});

// Use the VPC ID to get the VPC details
const vpcId = "your-vpc-id"; // replace with your VPC ID
const vpc = aws.ec2.getVpc({ id: vpcId }, { provider });

// Export the details of the VPC
export const vpcCidrBlock = vpc.then(v => v.cidrBlock);
```

This program uses `aws.ec2.getVpc` to get the VPC based on its ID. You'll need to replace `"your-vpc-id"` with your actual VPC ID. The `vpc` constant will hold a promise which resolves to the VPC details. Note that the VPC details are not immediately available because they're fetched asynchronously. Thus, if you want to access these details (like the `cidrBlock`), you need to use `then` function.

Once you run this program, you can retrieve the exported VPC CIDR block using the `pulumi stack output vpcCidrBlock` command in the CLI.
