1. Deploy the puppet-catalog-diff-viewer helm chart on Azure Kubernetes Service (AKS)


    Deploying the puppet-catalog-diff-viewer Helm chart on Azure Kubernetes Service (AKS) involves several steps. You will first need to create an AKS cluster. After which, you will install the Helm chart into your AKS cluster. Pulumi's @pulumi/azure-native and @pulumi/kubernetes packages provide the necessary components to accomplish these tasks.

    Firstly, you must import the required Pulumi packages and set up the Pulumi program. As a novice, you should know that Pulumi programs are structured like typical TypeScript programs, where you import libraries, create resources, and Pulumi takes care of the deployment and lifecycle management.

    Here's how you can achieve the deployment:

    1. We'll start by creating an AKS cluster using Pulumi's Azure Native package.
    2. Once the cluster is provisioned, we'll configure Pulumi to use the credentials for your AKS cluster so that it can manage resources in it.
    3. Finally, we'll deploy the Helm chart to the AKS cluster using Pulumi's Kubernetes package.

    Below is a detailed Pulumi program written in TypeScript that demonstrates these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create the AKS cluster const resourceGroupName = new azure_native.resources.ResourceGroup("myResourceGroup"); const cluster = new azure_native.containerservice.ManagedCluster("myCluster", { resourceGroupName: resourceGroupName.name, agentPoolProfiles: [{ count: 2, // Specifies the number of agents (VMs) to create in this agent pool vmSize: "Standard_DS2_v2", // The size of the VMs in the agent pool name: "agentpool" // The name of the agent pool }], dnsPrefix: "mydns", // DNS prefix specified when creating the AKS cluster kubernetesVersion: "1.20.7", // The version of Kubernetes to use linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "<your-ssh-rsa-public-key>" // Replace with your actual RSA public key }], }, }, enableRBAC: true, }); // Export the AKS cluster's kubeconfig export const kubeconfig = cluster.kubeConfigRaw; // Step 2: Configure Pulumi to use the AKS cluster credentials const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfigRaw, }); // Step 3: Deploy the Helm chart to the AKS cluster const puppetCatalogDiffViewerChart = new k8s.helm.v3.Chart("puppet-catalog-diff-viewer", { repo: "myhelmrepo", // Name of the Helm repository, replace with the actual name if necessary chart: "puppet-catalog-diff-viewer", // Name of the chart in the Helm repository version: "1.0.0", // Specify the chart version, ensure it’s available in the repo }, { provider: k8sProvider }); // Optionally, you can export endpoints or other resources that the Helm chart might provision.

    Please replace <your-ssh-rsa-public-key> with your actual SSH public key to allow secure access to the nodes within your AKS cluster.

    This Pulumi program does the following:

    • Sets up a new resource group in Azure to contain our AKS cluster.
    • Creates a new AKS cluster with a specified VM size and node count. It also sets up the adminUsername and ssh key for secure access.
    • The AKS cluster kubeconfig is exported so you can interact with your cluster using kubectl from your local machine.
    • A k8s.Provider resource is created to interact with your new AKS cluster using the generated kubeconfig. This Provider will be used for deploying Kubernetes resources.
    • Finally, the puppet-catalog-diff-viewer Helm chart is deployed using Pulumi's Helm Chart resource. This resource fetches the specified chart from the Helm repository and deploys it on the AKS cluster using the k8sProvider.

    Remember to replace the repo field with the actual name of the Helm repository where puppet-catalog-diff-viewer is located if it's different from "myhelmrepo", and also specify the correct version that you want to deploy.

    Before running pulumi up which deploys the program, make sure you have the @pulumi/azure-native and @pulumi/kubernetes packages installed, your Azure credentials configured, and Pulumi CLI set up appropriately on your system.

    After deploying the Helm chart, you can use kubectl to interact with your AKS cluster and confirm that the puppet-catalog-diff-viewer application is running as expected.
