Using aws kendra with us-west-2

Question

Pulumi · Accepted Answer

Amazon Kendra is a highly accurate and easy to use enterprise search service that's powered by machine learning. Kendra provides a more intuitive way to search through multiple content repositories using natural language queries. When you want to use AWS Kendra in your application, you can employ Pulumi as an Infrastructure as Code (IaC) tool to provision Kendra and other AWS resources programmatically. This allows for repeatable and version-controlled infrastructure.

Below is a Pulumi program in TypeScript that sets up a basic Kendra Index. An Index in Kendra is the foundational component that contains your data and handles the search queries.

First, we need to install the necessary Pulumi AWS package by running:

```bash
npm install @pulumi/aws
```

With the package installed, here's the program to create a basic Kendra Index resource in the `us-west-2` region of AWS:

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

// Create an Amazon Kendra Index
const kendraIndex = new aws.kendra.Index("myKendraIndex", {
    // The `EDITION` determines the features that will be available with the Kendra Index
    // Available options are ENTERPRISE_EDITION or DEVELOPER_EDITION
    edition: "DEVELOPER_EDITION",
    // You can specify AWS Tags here as key-value pairs if needed
    tags: {
        Project: "PulumiKendraProject"
    }
});

// Export the Kendra Index Id to access and manage it
export const kendraIndexId = kendraIndex.id;

```

In this program, an AWS Kendra Index is provisioned with a basic configuration. The `edition` is set to `DEVELOPER_EDITION`, which is a cost-effective option suitable for development and testing purposes. For production environments, you may opt for `ENTERPRISE_EDITION`.

The `tags` are optional key-value pairs that help you organize and identify your AWS resources. Here, the index is tagged with the Project name for better resource grouping.

Lastly, the program exports the Index Id using Pulumi's `export` statement, allowing you to reference this ID outside of Pulumi, such as in other automation scripts or AWS SDK calls.

After you write this code into a file (for example, `index.ts`), you can deploy the infrastructure by running the usual Pulumi commands:

```bash
pulumi up
```

Pulumi will prompt you for confirmation before creating the resources. Once confirmed, Pulumi applies the changes, and the Kendra Index will be created in your AWS account.

This is a very basic setup to get started with Amazon Kendra. Depending on your requirements, you may need to configure additional properties such as user access policies, data sources, and more.

For further information about AWS Kendra and related resources in Pulumi and what properties they accept, you can refer to the Pulumi documentation:

- [AWS Kendra Index](https://www.pulumi.com/registry/packages/aws/api-docs/kendra/index/)
- [AWS Kendra Data Source](https://www.pulumi.com/registry/packages/aws/api-docs/kendra/datasource/)
- [AWS Kendra FAQ](https://www.pulumi.com/registry/packages/aws/api-docs/kendra/faq/)

Keep in mind that AWS Kendra and the resources utilized have associated costs, which you can check on the AWS pricing page. Always clean up resources that are not in use to avoid incurring unnecessary charges. To delete resources managed by Pulumi, you can run:

```bash
pulumi destroy
```

Pulumi then will deprovision resources after confirmation. Remember to check out the Pulumi documentation for deeper insights into how Pulumi works and how you can use it to manage cloud resources effectively.
