1. Token-Based Authentication for Databricks REST API.


    Token-based authentication is a security technique where a user is granted a token, which acts as a security key to access services and resources. In the context of Databricks, a token can be used to authenticate and interact programmatically with the REST API.

    To set up token-based authentication for the Databricks REST API, we will use the databricks.Token resource from the Pulumi Databricks provider. This resource allows us to create, manage, and revoke authentication tokens which can be used to make authenticated requests to the Databricks REST API.

    Below is a Pulumi program written in Python that creates a Databricks token. This token will serve as our method of authentication to the REST API.

    import pulumi import pulumi_databricks as databricks # Create a new Databricks token databricks_token = databricks.Token("my-databricks-token", # You can add a comment to describe the purpose of this token comment="Token for accessing Databricks REST API" ) # Export the token ID and value so that it can be used outside of Pulumi. # The token value is sensitive and should be handled securely. pulumi.export('token_id', databricks_token.token_id) pulumi.export('token_value', databricks_token.token_value.apply(lambda value: pulumi.Output.secret(value)))

    In this program:

    • We import the necessary Pulumi libraries for the Databricks provider.
    • We create a new Token resource with a comment to explain its purpose.
    • Finally, we export both the token_id and token_value. The token_value is considered sensitive data, so it's wrapped in a call to pulumi.Output.secret. This will ensure that the token's value is encrypted and not displayed in plain text in the Pulumi logs or the Pulumi Console.

    With this token, you will be able to authenticate to the Databricks REST API. Remember that the token's value should be kept secret, as anyone with the token can access your Databricks resources according to the permissions associated with your user account.

    For additional information on how to interact with the Databricks REST API using the token or how to manage Databricks service principals and permissions, you can refer to the Databricks provider documentation.

    Please note that the token's value is only available during the initial creation of the token. It is not retrievable after the fact for security reasons. You should store it securely, for example, in a secret manager of your choice.
