Using aws redshiftserverless with rolesanywhere

Question

Pulumi · Accepted Answer

To use AWS Redshift Serverless with RolesAnywhere, you need to create a Redshift Serverless Namespace, which is essentially a container for your serverless database workload. Within a namespace, you can create an Amazon Redshift Serverless Workgroup, which allows you to run queries. You'll also need to configure IAM Roles to define access permissions.

Here's a step-by-step program in TypeScript using Pulumi that sets up a Redshift Serverless Namespace and Workgroup, configured to use IAM roles. To integrate with RolesAnywhere, you'd have to associate the respective IAM roles with your workgroup, but details for RolesAnywhere itself are not provided directly in Pulumi; you'd use AWS console or AWS CLI for part of that setup.

Let's walk through the Pulumi code:

1. **Set up Redshift Serverless Namespace**: This is where your serverless databases live. It requires a name, admin user credentials, and you can optionally configure other properties like KMS Key ID for encryption.

2. **Set up Redshift Serverless Workgroup**: A workgroup is used for running queries in Redshift Serverless. It requires a name, a namespace it belongs to, and you can optionally specify other settings like base capacity, VPC configurations, and so on.

3. **IAM Role Integration**: Although the specific integration with RolesAnywhere isn't reflected here due to the nature of the service and the current Pulumi capabilities, you could add IAM Roles to your namespace for access control.

Below is a Pulumi TypeScript program that defines a Redshift Serverless Namespace and Workgroup:

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

// Create a new Redshift Serverless Namespace
const redshiftServerlessNamespace = new aws.redshiftserverless.Namespace("my-namespace", {
    adminUsername: "adminuser",
    adminUserPassword: "SuperSecretPassword123!", // In production, use Pulumi's Secret management
    namespaceName: "my-namespace-name",
});

// Create a new Redshift Serverless Workgroup that uses the namespace created above
const redshiftServerlessWorkgroup = new aws.redshiftserverless.Workgroup("my-workgroup", {
    namespaceName: redshiftServerlessNamespace.namespaceName,
    workgroupName: "my-workgroup-name",
    baseCapacity: 32, // This is a parameter to specify the processing capacity
    // ... other optional configurations like VPC settings, public accessibility, etc. ...
});

// Export the Redshift Serverless namespace and workgroup ARNs
export const namespaceArn = redshiftServerlessNamespace.arn;
export const workgroupArn = redshiftServerlessWorkgroup.arn;

// IAM Role configuration would typically be set up here, but for full RolesAnyWhere
// features, additional AWS CLI or Console setup might be needed.

// Notes on IAM Roles and RolesAnywhere:
// Pulumi manages IAM roles, but AWS Roles Anywhere might require additional setup outside of Pulumi.
// For example, to associate an IAM role with this workgroup for access control, you'd create an IAM role
// and attach policies that grant permissions for required actions, and then associate the role with
// the workgroup. However, specific details on configuring RolesAnywhere to establish trust with external
// identities are managed outside of Pulumi at this time.
```

Here's what each section is doing:

- **Imports**: We're importing Pulumi AWS library to create AWS resources.
- **Redshift Serverless Namespace**: We set up a new namespace for our serverless databases, providing an admin username and password. Ensure that the admin password is secured correctly; in production, this should be a secret value managed by Pulumi's secret management.
- **Redshift Serverless Workgroup**: We then define a workgroup within that namespace. The `baseCapacity` parameter defines the processing power assigned to this workgroup.
- **Exports**: After creating these resources, we export their ARNs so we can reference them elsewhere. These could be endpoints used in the application configurations.

To fill all the gaps regarding RolesAnywhere, you'll need to visit the AWS documentation on RolesAnywhere and integrate any IAM roles created with your actual workgroup. The link to the documentation for creating a Redshift Serverless Namespace in Pulumi is [here](https://www.pulumi.com/registry/packages/aws/api-docs/redshiftserverless/namespace/) and for Workgroup is [here](https://www.pulumi.com/registry/packages/aws/api-docs/redshiftserverless/workgroup/).

Remember, while Pulumi provides you with the ability to codify your cloud infrastructure, certain actions and advanced configurations might still necessitate the use of AWS CLI commands or manual setups through the AWS Management Console.
