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


    To deploy the ublhub Helm chart on Azure Kubernetes Service (AKS) using Pulumi, you will go through several stages:

    1. Setting up AKS: We will create an AKS cluster, which involves specifying the node count, VM size, and other configurations.
    2. Deploying the Helm Chart: Using the Helm Pulumi provider, we will deploy the ublhub Helm chart into our AKS cluster.

    Below is a Pulumi TypeScript program that demonstrates these steps.

    Make sure you have the necessary Pulumi packages installed in your project. If not, you can add them using these commands:

    pulumi plugin install resource azure-native 2.11.0 pulumi plugin install resource kubernetes 4.4.0

    Here's the complete Pulumi program:

    import * as azure from "@pulumi/azure-native"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure.resources.ResourceGroup("resourceGroup"); // Create an AKS cluster const cluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 3, // The desired number of member nodes in the agent pool maxPods: 110, // The maximum number of pods per node mode: azure.containerservice.AgentPoolMode.System, osType: azure.containerservice.OSType.Linux, vmSize: azure.containerservice.ContainerServiceVMSizeTypes.Standard_D2s_v3, }], dnsPrefix: "akscluster", // A DNS prefix for the cluster enableRBAC: true, // Enable Kubernetes RBAC for the cluster kubernetesVersion: "1.22.5", // The version of Kubernetes to use sku: { name: "Basic", tier: "Free" }, }); // Export the Kubeconfig export const kubeconfig = cluster.kubeConfigRaw; // Create a Kubernetes provider instance using the kubeconfig from AKS const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfigRaw, }); // Deploy the ublhub helm chart const ublhubChart = new k8s.helm.v3.Chart("ublhub", { chart: "ublhub", // The name of the chart // You might need to specify the repository using `repo` property, if it's not a stable chart values: { /* ... */ }, // Values to configure the chart version: "1.2.3", // The chart version to deploy }, { provider: k8sProvider }); // Expose the required information from the Helm chart, like service URLs and other data export const helmValues = ublhubChart.values;

    The above program will perform the following actions:

    1. ResourceGroup resource creates a new group in Azure to hold our AKS-related services.
    2. ManagedCluster resource sets up a new AKS cluster with three nodes of size 'Standard_D2s_v3'.
    3. The output kubeconfig would give you the configuration needed to connect to the AKS cluster with kubectl.
    4. Provider resource creates a Kubernetes provider initialized with the AKS cluster's kubeconfig.
    5. Chart resource then deploys the Helm chart to the AKS cluster using the values provided.

    The values field in the Helm chart needs to be customized according to the specifics of the ublhub chart, and if the chart isn't part of the official Helm stable charts, you'll also need to specify the repo property with the URL to the Helm chart repository.

    Remember to replace "1.2.3" with the actual version number of the ublhub Helm chart you intend to deploy.

    How to run this Pulumi program:

    To use this program, you would:

    1. Create a new directory for your Pulumi project.
    2. Run pulumi new typescript in your terminal to initialize a new Pulumi TypeScript project.
    3. Replace the contents of index.ts with the program provided above.
    4. Run npm install to get all the necessary node modules.
    5. Run pulumi up to deploy the AKS cluster and the Helm chart.

    This will trigger the setup of the AKS cluster, and once that's completed, the Helm chart for ublhub will be deployed using the configurations defined.
