1. Automating AI/ML Pipelines using Harness


    Automating AI/ML pipelines can be a complex task, which often involves configuring multiple services and managing their interactions. In the context of Pulumi, this could involve setting up a series of orchestrated tasks that perform data collection, preprocessing, model training, evaluation, and deployment. To automate these tasks using Harness, you would typically rely on Harness's platform to define pipelines, environments, services, and infrastructure.

    Let's put together a Pulumi program in Python to create a simple AI/ML pipeline using Harness. The pipeline will consist of the following components:

    • Project: A project in Harness to organize our resources.
    • Pipeline: A pipeline that defines the workflow for our AI/ML tasks.
    • Service: This will represent our AI/ML service, including model training and deployment.

    Firstly, to interact with Harness's platform, we will use the pulumi_harness package that offers various resources to be managed via Pulumi. In this example, we will create a project, a pipeline within that project, and assign services to the pipeline.

    Below is the Pulumi program that sets up the basic structure for automating AI/ML pipelines using Harness:

    import pulumi import pulumi_harness as harness # Note: Replace `<organization-identifier>` with your Harness organization identifier # and `<project-identifier>` with your desired project identifier. # Create a Harness Project to organize our AI/ML resources ml_project = harness.Project("ml-project", name="MLProject", color="#8a2be2", # Typically an RBG hex string identifier="<project-identifier>", # A unique identifier for the project description="A project to orchestrate AI/ML pipelines" # orgId="<organization-identifier>" # Only specify if the organization is not the default ) # Define an AI/ML pipeline in Harness ml_pipeline = harness.Pipeline("ml-pipeline", name="MLPipeline", yaml="""<pipeline-yaml-configuration>""", # YAML string defining the pipeline's stages and steps identifier="ml-pipeline-identifier", project_id=ml_project.identifier, # orgId="<organization-identifier>", # Only specify if the organization is not the default description="Pipeline to manage AI/ML workflow" ) # Define a Service for the AI/ML application ml_service = harness.Service("ml-service", name="MLService", yaml="""<service-yaml-configuration>""", # YAML string defining service configuration identifier="ml-service-identifier", project_id=ml_project.identifier, # orgId="<organization-identifier>", # Only specify if the organization is not the default description="Service to run AI/ML model training and deployment" ) # Export the project and pipeline identifiers pulumi.export("project_id", ml_project.identifier) pulumi.export("pipeline_id", ml_pipeline.identifier) pulumi.export("service_id", ml_service.identifier)

    In the Pulumi program above:

    • We import Pulumi and the pulumi_harness package.
    • A Project resource is created to organize our pipeline and services. It has a name, an optional color (typically an RBG hex string), a unique identifier, and a description.
    • A Pipeline resource is declared inside our project. It includes a name, the YAML configuration for the pipeline, a unique identifier, an associated project identifier, and a description. You will replace <pipeline-yaml-configuration> with the actual YAML configuration describing your pipeline's stages and steps.
    • A Service resource is also declared to represent our AI/ML application. This could include model training and deployment configuration. You will replace <service-yaml-configuration> with the actual YAML configuration defining your service.
    • We do not specify orgId where it's commented because we assume that the organization is already selected in the default configuration.
    • Finally, We use pulumi.export to output the identifier of the created resources, which can be useful for referencing them outside of Pulumi, such as in CI/CD pipelines or for debugging.

    For this Pulumi program to run, you must replace placeholder values with actual configurations specific to your Harness setup:

    • <organization-identifier> with your Harness organization identifier,
    • <project-identifier> with your desired project identifier,
    • <pipeline-yaml-configuration> with your pipeline's YAML definition,
    • <service-yaml-configuration> with your service's YAML definition.

    Before running this program, ensure you have Pulumi installed, a Pulumi account set up, and the Pulumi CLI correctly configured to access your Harness account, including necessary credentials. Also, install the pulumi_harness package by running pip install pulumi_harness. Once the setup is ready, you can run pulumi up to create the resources as described in the program.
