Token Authentication for AI Data Lakes Using Okta OAuth

Question

Pulumi · Accepted Answer

To create an AI Data Lake infrastructure that uses Okta OAuth for token authentication, you'll need to integrate several services. It's common to implement an AI Data Lake within a cloud provider such as AWS, Azure, or GCP, using their respective data storage solutions. However, for token authentication with Okta OAuth, you will typically have external software that integrates with Okta to manage and authenticate tokens.

In the context of Pulumi, there isn't a direct resource to create this entire system in one go, as it requires integration between third-party identity providers like Okta and cloud services.

However, Pulumi can facilitate creating the necessary cloud infrastructure and configuring the pieces that will communicate with Okta. For example, suppose we were to architect this within AWS. In that case, we might create an Amazon S3 bucket for the Data Lake and an AWS Cognito User Pool that integrates with Okta as an identity provider. The authentication flow could look like this:
1. Authenticate with Okta and acquire an OAuth token.
2. The OAuth token is used to authenticate against AWS Cognito, configured to trust Okta as an identity provider.
3. Upon successful authentication, AWS Cognito provides AWS credentials scoped to the user, allowing them to access resources like the S3 Data Lake securely.

Here is a simplified Pulumi program in Python that sets up an AWS Data Lake (S3 bucket) and configures AWS Cognito to work with an external identity provider (Okta is not explicitly integrated in this example as it typically involves specific Okta setup which is not directly part of Pulumi's library):

```python
import pulumi
import pulumi_aws as aws

# Create an AWS S3 bucket to be used as the Data Lake
data_lake_bucket = aws.s3.Bucket("dataLakeBucket",
    acl="private",
    versioning=aws.s3.BucketVersioningArgs(
        enabled=True,
    )
)

# Configuring AWS Cognito User Pool to work with an external identity provider
# For actual Okta integration, configuration will require the details from your Okta application
# and may not be directly supported by Pulumi. You will need to set up these details in Okta and
# AWS Cognito manually or through their respective consoles/APIs.

# Create an AWS Cognito User Pool
user_pool = aws.cognito.UserPool("userPool")

# ASSUMPTION: At this point, we expect the user has already configured Okta as an identity provider
# through the AWS Management Console or AWS CLI, because Pulumi currently does not have direct support
# for configuring external identity providers in AWS Cognito User Pools.
# You can typically do this configuration under the "Identity Providers" section of the AWS Cognito console,
# providing the required details such as the Okta app client ID, client secret, and Okta domain.

# Assume that the setup is done, we can, for example, create a Cognito User Pool Client
# which your application can use to interact with the user pool.
user_pool_client = aws.cognito.UserPoolClient("appClient",
    user_pool_id=user_pool.id,
)

# The application would redirect users to authenticate with Okta, which upon successful authentication,
# will return a token used to interact with AWS services like S3

pulumi.export('data_lake_bucket_name', data_lake_bucket.id)
pulumi.export('user_pool_id', user_pool.id)
pulumi.export('user_pool_client_id', user_pool_client.id)
```

Let's go over the code:

- We created an S3 bucket which will serve as our data lake.
- We also set up a skeleton AWS Cognito User Pool to demonstrate the kind of resource you would use in AWS for integrating with an identity provider like Okta. The user pool client would be part of the larger OAuth flow.

For the actual integration with Okta, you don't just need a resource within AWS, but you need to set up Okta to trust AWS Cognito as well. This involves creating an Okta application, configuring it to work with AWS, and then adding it as an identity provider within the Cognito User Pool.

This Pulumi program sets the infrastructure stage, but the detailed configuration of the identity provider in AWS Cognito and the setup in Okta will need to be done outside of Pulumi through their respective interfaces or APIs. Once that is in place, your application can redirect users to Okta for login, receive an OAuth token upon successful authentication, and then use that token to access the AWS S3 data lake securely through AWS Cognito-supplied credentials.
