1. Deploy the mlflow-helm-chart helm chart on Azure Kubernetes Service (AKS)


    To deploy the mlflow-helm-chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, you would first need to ensure you have an AKS cluster created and configured, which you can do with Pulumi's azure-native package. Next, you would deploy the Helm chart to AKS using kubernetes.helm.v3.Chart from the @pulumi/kubernetes package.

    Here's how this process might look:

    1. Create an AKS cluster: Define an AKS cluster in your Pulumi program.
    2. Configure Kubernetes provider: Use the cluster's kubeconfig to configure your Kubernetes provider so that Pulumi can communicate with your AKS cluster.
    3. Deploy Helm Chart: Finally, use the Helm Chart resource to deploy your mlflow-helm-chart onto the AKS cluster.

    Below is a TypeScript program that demonstrates these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; const config = new pulumi.Config(); // This assumes that the Pulumi program is configured with the necessary Azure settings, such as subscription, client ID, and tenant ID. // Step 1: Create the AKS cluster const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); const cluster = new azure_native.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, kubernetesVersion: "1.18.14", agentPoolProfiles: [{ count: 3, vmSize: "Standard_DS2_v2", osType: "Linux", mode: "System", name: "agentpool" // Name of the agent pool }], dnsPrefix: `${pulumi.getStack()}-kubernetes`, linuxProfile: { adminUsername: "testuser", ssh: { publicKeys: [{ keyData: "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQD..." }], }, }, identity: { type: "SystemAssigned" } }); // Export the kubeconfig export const kubeconfig = cluster.kubeConfig; // Step 2: Configure the Kubernetes provider to use the kubeconfig from the created AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfig.apply(kc => kc), }); // Step 3: Deploy the mlflow-helm-chart using the Helm Chart resource const mlflowChart = new k8s.helm.v3.Chart("mlflow-helm-chart", { chart: "mlflow", // This assumes that the "mlflow" chart is available in the specified Helm repository. // Make sure to specify the correct Helm repository URL and chart name. version: "0.1.0", fetchOpts: { repo: "http://myhelmrepo.com" }, }, { provider: k8sProvider }); // Export the mlflow Helm chart deployment status export const mlflowChartStatus = mlflowChart.status;


    • Resource Group: This is the fundamental Azure resource that contains and groups other resources like AKS clusters and other services.

    • Managed Cluster: This AKS cluster is created with one system mode agent pool which is the node pool that the Kubernetes workloads will run on. The provided kubernetesVersion would be the version of Kubernetes that you want to use on your AKS cluster. The dnsPrefix ensures your API server has a unique DNS name within Azure.

    • Kubeconfig: The output from the Managed Cluster, which contains credentials for accessing the Kubernetes cluster. This is required for setting up the Kubernetes provider.

    • Kubernetes Provider: This provider allows Pulumi to interact with the Kubernetes cluster, deploying resources onto it.

    • Helm Chart: This is a Pulumi resource that represents a Helm chart deployment. It uses the chart name and version you specify, along with the repo where the chart is hosted. You need to make sure the mlflow exists in the specified repository.

    Remember to replace placeholder values with actual values appropriate for your scenario, such as keyData with your actual SSH public key, and the repo with the location of the Helm chart for mlflow.

    Once the program is ready, you would run it using the Pulumi CLI. First, you would execute pulumi up to provision the resources. The resources will be deployed in the following order: the resource group, the AKS cluster, and then the Helm chart will be deployed to that cluster.
