1. Access Control for Machine Learning Pipelines with Vault KV


    To set up access control for Machine Learning (ML) Pipelines using HashiCorp Vault's Key-Value (KV) secrets engine, you first need to include the Vault Pulumi package in your infrastructure as code. HashiCorp Vault is an identity-based secret and encryption management system that enables you to securely store, access, and distribute secrets such as tokens, passwords, certificates, and API keys.

    In the context of ML pipelines, you might want to store sensitive information like database credentials, API keys for different services, or configurations that your ML application needs to access at runtime. Vault KV secrets engine allows you to securely store and manage this information.

    Pulumi provides integration with Vault through the pulumi_vault package. The vault.kv.Secret resource allows you to manage a secret in the KV store, and the vault.kv.SecretV2 handles version 2 of the KV secrets engine, which supports versioning and other advanced features.

    Below is a Pulumi program written in Python that demonstrates how to create secrets in Vault KV for an ML pipeline. This program manages a secret in the KV store using Vault and assumes that you already have a Vault server up and running, and Pulumi is configured appropriately to interact with it.

    import pulumi import pulumi_vault as vault # Create a secret in the KV store ml_secrets = vault.kv.Secret("mlSecrets", path="path/to/ml_secrets", data_json="{\"db_password\": \"mysecurepassword\", \"api_key\": \"mysecureapikey\"}") # Export the path where the secrets are stored pulumi.export("secret_path", ml_secrets.path)

    In this code:

    • We import the required modules: pulumi and pulumi_vault.
    • We use the vault.kv.Secret resource to create a new secret. The path argument specifies the location within the Vault where the secret will reside. The data_json argument contains the actual secrets in JSON format, which in a real-world scenario would be externalized into configuration or generated dynamically.
    • The pulumi.export function is used to output the secret's path for reference.

    Make sure that you do not hard-code sensitive information like actual secrets into your version control. This is a basic example to illustrate the usage. In a production setup, you should always retrieve such secrets at runtime from a secure location or inject them securely using Pulumi's configuration system.

    Remember that to run this code, you must have appropriate permissions set up in Vault and your Pulumi environment must be authenticated with Vault. You must also handle the version of the KV engine (either v1 or v2), as there are some differences in how they're managed.

    Please replace the placeholder secrets (mysecurepassword, mysecureapikey) with the real secrets that your ML pipeline requires, and the path to the Vault path where you want to store these secrets.
