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


    Deploying applications on a Kubernetes cluster often involves a number of steps; from setting up the Kubernetes cluster itself, to deploying the applications using various methods such as helm charts. Helm is a package manager for Kubernetes, which allows you to define, install, and upgrade even the most complex Kubernetes applications.

    Below you'll find a step-by-step guide and a Pulumi program written in TypeScript that demonstrates how to:

    1. Create an Azure Kubernetes Service (AKS) cluster using Pulumi's azure-native provider
    2. Deploy a Helm chart to the AKS cluster, specifically the ActiveMQ Broker (helm-amq-broker) chart

    Step-by-Step Guide

    1. Set up Azure with Pulumi: Before running the code, ensure you have set up the Pulumi Azure provider by logging in using the pulumi login command and setting Azure credentials via the Azure CLI with az login.

    2. Create a Resource Group: In Azure, a Resource Group serves as a logical container into which Azure resources like web apps, databases, and storage accounts are deployed and managed.

    3. Create an AKS Cluster: In this step, we will define an AKS cluster resource using Pulumi.

    4. Deploy a Helm Chart: Once the AKS cluster is set up, we'll deploy the helm-amq-broker Helm chart. This will create a running instance of that service within our AKS cluster.

    First, you need to have Node.js and Pulumi installed. You also have to be logged in to both Azure and Pulumi CLI.

    Here is the TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as azure from "@pulumi/azure-native"; // Create a resource group const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup"); // Create the AKS cluster const cluster = new azure.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, vmSize: "Standard_DS2_v2", name: "agentpool", mode: "System", }], dnsPrefix: "myakscluster", }); // Export the kubeconfig for the cluster export const kubeConfig = pulumi.all([cluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceName: clusterName, resourceGroupName: rgName, }); }).apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Create a k8s provider using the kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeConfig, }); // Deploy the helm-amq-broker helm chart const helmChart = new k8s.helm.v3.Chart("amq-broker", { chart: "amq-broker", version: "0.1.0", fetchOpts: { repo: "https://helm-repo-url/where/chart/is/located/", }, }, { provider: k8sProvider }); // Export the Public IP address of the AMQ Broker export const amqBrokerPublicIp = helmChart.getResourceProperty("v1/Service", "amq-broker", "status").apply(s => s.loadBalancer.ingress[0].ip);

    This program performs the following actions:

    • Imports the necessary Pulumi libraries to interact with Azure and Kubernetes.
    • Creates a new resource group within your Azure subscription to contain our AKS cluster and associated resources.
    • Defines an AKS cluster with a single node pool consisting of two nodes of a certain VM size.
    • Retrieves the kubeconfig from the generated AKS cluster, which is necessary for the Kubernetes provider to interact with our AKS cluster.
    • Creates an instance of a Pulumi Kubernetes provider using the obtained kubeconfig from the AKS cluster.
    • Deploys the amq-broker helm chart to the AKS cluster using the previously created Kubernetes provider. The version and repo fields should match the specifics of the helm chart you want to deploy.
    • Exports the public IP address of the AMQ Broker once deployed, allowing you to interact with it from outside the cluster.

    Please, replace https://helm-repo-url/where/chart/is/located/ with the actual Helm repository URL where the amq-broker chart is located. You can find official Helm charts in many public repositories or use your own if you have a custom chart.

    Remember to configure your Pulumi project correctly with the proper Azure region and subscription settings. To get started with Pulumi and for more detailed setup instructions, visit the Pulumi documentation.
