1. OpenID Connect Provider for Secure Sagemaker Notebook Authentication


    To secure a SageMaker notebook instance using an OpenID Connect (OIDC) provider, you would typically need to establish an identity provider that can integrate with AWS Identity and Access Management (IAM). This allows you to use identity federation to grant secure access to your SageMaker notebook instance.

    Here's a program written in Pulumi with Python which sets up an AWS IAM OpenID Connect Provider. This OIDC provider can then be used to set up federated access with AWS and potentially link it to a SageMaker instance, although setting up the complete authentication flow for SageMaker is outside the scope of this code. In a production environment, you would also want to attach an IAM role to your SageMaker notebook instance with appropriate policies that trust this OIDC provider.

    Make sure you replace <oidc-provider-url> and <client-id-list> with the actual URL of your OIDC provider and the list of client IDs expected to be associated with the OIDC provider, respectively.

    Here's how you could set up the OIDC provider in Pulumi:

    import pulumi import pulumi_aws as aws # Create an IAM OpenID Connect Provider oidc_provider = aws.iam.OpenIdConnectProvider("sagemaker_oidc_provider", url="<oidc-provider-url>", # The URL of the OIDC Identity Provider that allows IAM to establish a trust relationship client_id_lists=["<client-id-list>"], # A list of client IDs (also known as audiences) thumbprint_lists=["<thumbprint>"], # A list of server certificate thumbprints for the OpenID Connect (OIDC) identity provider's server certificate(s) ) # pulumi.export is used to export the output variables which will be visible after deployment pulumi.export('oidc_provider_arn', oidc_provider.arn)

    In the program above:

    • We import the pulumi_aws module, which allows us to interact with AWS resources.
    • We create an aws.iam.OpenIdConnectProvider resource, representing the OIDC Provider in IAM.
      • url is set to the Issuer URL of the OIDC identity provider; replace <oidc-provider-url> with your provider's URL.
      • client_id_lists is a list of client IDs that are allowed to authenticate; replace <client-id-list> with your provider's client IDs.
      • thumbprint_lists contains a list of CA certificates thumbprints; replace <thumbprint> with the thumbprint corresponding to your OIDC provider's CA certificate.

    Finally, we export the ARN of the OIDC provider, which uniquely identifies the provider in AWS. You could use this ARN to set up trust relationships in roles that your SageMaker notebook instance would assume.

    Remember that for a fully operational flow where a SageMaker notebook instance uses this OIDC for authentication, additional steps would be needed. You would have to:

    • Set up a trust policy in an IAM role to allow federated users via the OIDC provider.
    • Attach the trust policy to the role and assign permissions to it that SageMaker notebook instances need.
    • Configure your SageMaker instance to assume the role with the trust policy.

    The Pulumi program lays the groundwork for setting up the OIDC provider, but the complete integration with SageMaker for a secure authentication flow involves a few more steps on both the AWS side and potentially within your own application or identity provider setup.
