Using cloudflare dnsrecord with cloudflareinstallation

Question

Pulumi · Accepted Answer

To use the Cloudflare DNS record in conjunction with a Cloudflare setup using Pulumi, we can employ the Cloudflare Pulumi provider. The Cloudflare provider allows you to manage Cloudflare services including DNS records, zones, and more.

Below is a TypeScript program using Pulumi to create a Cloudflare DNS record. This program assumes that you have already set up a Cloudflare account, have your API token ready, and a domain managed by Cloudflare. We will use the `cloudflare.Record` resource to create a DNS record and assume that you have a particular zone ID that you want to create the record in.

Here's how you would use Pulumi to create a DNS record in Cloudflare:

1. First, we install the necessary Cloudflare Pulumi package using npm or yarn.

2. Next, we import the required modules from both Pulumi and the Cloudflare provider.

3. We then create a new DNS record using `new cloudflare.Record`.

4. For this example, we’re creating an A record for `www.example.com` with an IP address `192.0.2.1` and a Time-To-Live (TTL) of 3600 seconds.

To begin, you will need to install the Pulumi Cloudflare package:

```bash
npm install @pulumi/cloudflare
```

Now, let's write the program:

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

// Replace these variables with appropriate values
const zoneId = "your-zone-id"; // Your Cloudflare Zone ID
const recordName = "www"; // The name of the record to create
const domain = "example.com"; // Your domain
const targetIp = "192.0.2.1"; // The IP address the DNS record will point to
const ttl = 3600; // Time to live for DNS cache

// Create a Cloudflare DNS A record for www.example.com
const dnsRecord = new cloudflare.Record(`${recordName}.${domain}`, {
    // Resource documentation: https://www.pulumi.com/registry/packages/cloudflare/api-docs/record/
    zoneId: zoneId,
    name: recordName,
    type: "A",
    value: targetIp,
    ttl: ttl,
});

// Export the DNS record ID
export const dnsRecordId = dnsRecord.id;
```

In this program:

- We specify the zone ID where you want to create the DNS record. You can find this in your Cloudflare dashboard under the DNS section of your domain.

- We set the `name` to `'www'` to create a record like `www.example.com`.

- The `type` is `'A'` which is a standard DNS record type, pointing a domain to an IPv4 address.

- The `value` should be changed to the IP address where you want `www.example.com` to resolve.

- `ttl` is the Time-to-Live which determines how long DNS resolvers are allowed to cache this record before requesting it again. 3600 seconds is a typical default.

At the end of the script, we have an export statement that will output the ID of the created DNS record. After running this program with Pulumi, you'll get the output of the record's ID printed on the console, which you can use for reference.

This is a basic example to get you started with managing DNS records with Pulumi and Cloudflare. You can adjust the `name`, `type`, `value`, and other properties to create different types of DNS records according to your needs.
