1. Deploy the mlflow-helm-chart helm chart on Rancher


    To deploy the mlflow-helm-chart on Rancher using Pulumi, you'll need to set up a few things:

    1. Rancher Kubernetes Cluster: First, you'll need to have a Kubernetes cluster managed by Rancher. You can use any cloud provider supported by Rancher to create this cluster (e.g., AWS, Azure, Google Cloud).

    2. Helm Setup: Ensure Helm is set up in your Rancher cluster since you'll be deploying a Helm chart.

    3. Pulumi Setup: You need to have the Pulumi CLI installed and set up with credentials for Rancher.

    For the purpose of this guide, I'll assume you've already set up a Kubernetes cluster through Rancher and are ready to deploy Helm charts to it. If not, you can refer to the Rancher documentation for creating and managing clusters.

    Now, let's proceed with how you would write a Pulumi program to deploy the mlflow-helm-chart on your Rancher-managed Kubernetes cluster. We will be using the Pulumi Rancher2 provider for this purpose.

    Detailed Explanation

    The Helm chart for MLflow is not part of the Rancher Catalog by default, so you would typically need to add a catalog to Rancher for the Helm repository that includes MLflow. However, for simplicity and because catalog management is beyond the scope of what we are doing, we will directly apply Helm chart configurations as if the chart is available in your cluster environment.

    The following program provides the steps in TypeScript, showing:

    • How to import the required packages.
    • How to construct a helm release resource which references the mlflow-helm-chart.

    Here is the Pulumi TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Create an instance of the Rancher2 provider. const rancher2Provider = new rancher2.Provider("rancher-provider", { // You will need to provide the actual API URL and the access key for your Rancher Server. apiUrl: "https://<your-rancher-server-url>", accessKey: "<your-rancher-access-key>", secretKey: "<your-rancher-secret-key>", }); // Create an instance of the Pulumi Kubernetes provider using credentials from your Rancher cluster. const k8sProvider = new kubernetes.Provider("k8s-provider", { // You should configure your Kubeconfig to point to your Rancher-managed cluster. // This often involves running `rancher kubectl config` to fetch the necessary kubeconfig file. kubeconfig: "<your-cluster-kubeconfig>", }); // Deploying the MLflow Helm chart const mlflowHelmChart = new kubernetes.helm.v3.Chart("mlflow", { chart: "mlflow-helm-chart", // Specify the Helm chart version you want to deploy. version: "<chart-version>", // Replace with the actual repository that hosts the `mlflow-helm-chart`. fetchOpts: { repo: "http://<helm-chart-repository-url>", }, // Optionally, specify any values here that the chart needs. values: { // Your values go here. }, }, { provider: k8sProvider }); // Export the name of the chart deployment export const mlflowHelmChartName = mlflowHelmChart.metadata.apply(metadata => metadata.name);

    Resource Explanation

    • @pulumi/pulumi: This is the core Pulumi library that allows you to declare resources and outputs.

    • @pulumi/kubernetes: The Pulumi Kubernetes provider plugin that allows Pulumi to interact with Kubernetes resources, like the Helm chart in this case.

    • @pulumi/rancher2: The Pulumi Rancher2 provider plugin that is used to interact with Rancher.

    • rancher2.Provider: This is the Rancher2 provider configuration where you provide access to your Rancher server by specifying the apiUrl, accessKey, and secretKey.

    • kubernetes.Provider: This defines the Kubernetes provider from your Rancher-managed cluster; the kubeconfig provided here is what allows Pulumi to communicate with your cluster.

    • kubernetes.helm.v3.Chart: This resource defines a Helm chart deployment. It references the Helm chart for MLflow which must be available to your Kubernetes cluster. You need to replace <helm-chart-repository-url> and <chart-version> with the correct URL to the repository that contains the mlflow-helm-chart and the version of the chart you wish to deploy. The values field is a placeholder where you can specify any configurations that are necessary for your MLflow Helm chart.

    Please replace the placeholders like <your-rancher-server-url>, <your-rancher-access-key>, <your-rancher-secret-key>, <your-cluster-kubeconfig>, <chart-version>, and <helm-chart-repository-url> with actual values that correspond to your environment and the mlflow Helm chart you want to deploy.

    Make sure you have these packages installed in your Pulumi project (package.json):

    { "dependencies": { "@pulumi/pulumi": "^3.0.0", "@pulumi/kubernetes": "^3.0.0", "@pulumi/rancher2": "^5.0.0" } }

    Run npm install or yarn install to download these libraries before running the Pulumi program using the pulumi up command.

    Remember to configure the access to your Rancher server and your cluster appropriately, and ensure that Helm is configured within the cluster to allow for chart deployments.
