1. Deploy the tt-workflow-driver helm chart on Azure Kubernetes Service (AKS)


    To deploy the tt-workflow-driver Helm chart on Azure Kubernetes Service (AKS) using Pulumi, we'll follow these steps:

    1. Set up an AKS cluster.
    2. Install the Helm chart on the AKS cluster.

    We'll use the azure-native provider for Pulumi, which offers native Azure Resource Manager (ARM) resource provisioning. First, we create an AKS cluster by defining the necessary resources such as resource group, Kubernetes cluster itself, and then configure the Kubernetes provider to interact with that cluster.

    After the AKS cluster is running, we deploy the Helm chart to it. For deploying Helm charts, Pulumi provides a Chart resource in the Kubernetes provider which encapsulates Helm's chart deployment capabilities.

    Here's the complete program in TypeScript demonstrating how you could set this up:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); // Create an AKS cluster const cluster = new azure_native.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 1, vmSize: azure_native.containerservice.ContainerServiceVMSizeTypes.Standard_D2_v2, mode: "System", name: "agentpool" }], dnsPrefix: "myakscluster", }); // Export the AKS cluster's kubeconfig export const kubeconfig = cluster.kubeConfig; // Create a Kubernetes provider instance that uses our AKS cluster kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfig.apply(JSON.stringify), }); // Deploy the tt-workflow-driver Helm chart const helmChart = new k8s.helm.v3.Chart("tt-workflow-driver", { repo: "myhelmrepo", // Replace with the repository where your helm chart is hosted chart: "tt-workflow-driver", version: "1.0.0", // Replace with the specific version you wish to deploy }, { provider: k8sProvider }); // To access the Helm release status, name and other details you could export them like this: export const helmReleaseStatus = helmChart.status; export const helmReleaseName = helmChart.releaseName;

    In the program:

    • We import the necessary modules from Pulumi.
    • We instantiate a ResourceGroup which will contain all our AKS resources.
    • We create an AKS cluster using ManagedCluster, defining the size and count of nodes in our node pool.
    • We export the kubeconfig from our AKS cluster which allows us to interact with it using kubectl or any Kubernetes client.
    • We create a Provider resource that specifies how to communicate with our AKS cluster using the kubeconfig.
    • We deploy the tt-workflow-driver Helm chart with Chart resource and specify the repository and version of the chart.

    Remember to replace myhelmrepo and the version 1.0.0 with the actual Helm repository URL and chart version you intend to use.

    To run this program:

    1. Save this code to a file with a .ts extension, for example aksHelmDeploy.ts.
    2. Run pulumi up to preview and then perform the deployment.

    This command will execute the Pulumi program, create all of the Azure resources, and then deploy your Helm chart onto the AKS cluster it just provisioned.

    After deployment, you can manage the lifecycle of the Helm chart deployment (such as upgrades or rollbacks) using additional Pulumi code or by using the Helm CLI, interfacing with the Kubernetes cluster using the exported kubeconfig.
