1. Deploy the ms-java-spring-boot helm chart on Azure Kubernetes Service (AKS)


    To deploy the ms-java-spring-boot Helm chart on Azure Kubernetes Service (AKS), we first need to create an AKS cluster if you don't have one already. Then we'll be using the Pulumi's @pulumi/azure-native package to create the necessary resources for AKS as well as the @pulumi/kubernetes package to deploy the Helm chart.

    Below I will walk you through the TypeScript code for deploying an AKS cluster and then deploying the ms-java-spring-boot Helm chart using Pulumi.

    Let's start by installing the necessary npm packages:

    • @pulumi/pulumi: The core Pulumi SDK.
    • @pulumi/azure-native: The Pulumi Azure Native package to manage Azure resources.
    • @pulumi/kubernetes: The Pulumi Kubernetes package to manage Kubernetes resources, like Helm charts.
    npm install @pulumi/pulumi @pulumi/azure-native @pulumi/kubernetes

    Next, we will create two primary resources:

    1. An AKS cluster using the azure-native.containerservice.KubernetesCluster resource.
    2. A Helm chart deployment using the kubernetes.helm.v3.Chart resource.

    Here is the full program.

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as kubernetes from "@pulumi/kubernetes"; import * as random from "@pulumi/random"; // We start by creating a new resource group in Azure where our AKS resources will live. const resourceGroupName = new azure_native.resources.ResourceGroup("myResourceGroup").name; // Create an AD service principal for the K8s cluster. const adApp = new azure_native.graphrbac.Application("adApp"); const adSp = new azure_native.graphrbac.ServicePrincipal("adSp", { applicationId: adApp.applicationId, }); const password = new random.RandomPassword("password", { length: 20, special: true, }); const adSpPassword = new azure_native.graphrbac.ServicePrincipalPassword("adSpPassword", { servicePrincipalId: adSp.id, value: password.result, endDate: "2099-01-01T00:00:00Z", }); // Now let's create the AKS cluster. const cluster = new azure_native.containerservice.KubernetesCluster("myAKSCluster", { resourceGroupName: resourceGroupName, agentPoolProfiles: [ { count: 1, // Single node cluster for simplicity, adjust count as needed. vmSize: "Standard_DS2_v2", // VM size for the nodes, select based on your needs. mode: "System", // Required property for the first node pool, which is the default. name: "agentpool" // Name of the node pool. }, ], dnsPrefix: "aksdns", // DNS prefix for the AKS cluster. linuxProfile: { adminUsername: "adminuser", // Admin user for the Linux VMs. ssh: { publicKeys: [{ keyData: "<INSERT YOUR PUBLIC SSH KEY HERE>" }], }, }, kubernetesVersion: "1.18.14", // Specify your desired Kubernetes version. servicePrincipalProfile: { clientId: adApp.applicationId, secret: adSpPassword.value, }, }); // We need to get the kubeconfig from AKS to be used by the Helm chart to deploy // the ms-java-spring-boot application. const creds = pulumi.all([resourceGroupName, cluster.name]).apply(([rgName, clusterName]) => azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, })); const kubeconfig = creds.apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Create a Kubernetes provider instance that uses our kubeconfig. const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the ms-java-spring-boot Helm chart into our AKS cluster. const springBootChart = new kubernetes.helm.v3.Chart("ms-java-spring-boot", { chart: "ms-java-spring-boot", version: "1.0.0", // Replace with the desired version of the Helm chart. fetchOpts: { repo: "http://<HELM REPO URL HERE>", // Specify the Helm repository URL. }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and public IP endpoints for the service. export const kubeconfigOut = kubeconfig; export const frontendServiceIp = springBootChart.getResourceProperty("v1/Service", "ms-java-spring-boot", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Replace <INSERT YOUR PUBLIC SSH KEY HERE> and <HELM REPO URL HERE> with your SSH public key and the URL of your Helm chart repository.

    Please note that handling secrets like adSpPassword.value inline is not recommended for production. Instead consider using Pulumi's secrets management or store secrets in Azure Key Vault.

    What the program does:

    1. Creates a new resource group.
    2. Sets up an Azure Active Directory application and service principal for AKS to interact with other Azure services.
    3. Generates a strong password for the service principal account.
    4. Creates an AKS cluster with one node.
    5. Retrieves AKS credentials to interact with the cluster using listManagedClusterUserCredentials.
    6. Converts the retrieved credentials to a kubeconfig file inline.
    7. Initializes a Pulumi Kubernetes provider with this kubeconfig.
    8. Deploys the ms-java-spring-boot Helm chart to the AKS cluster using this provider.
    9. Exports the kubeconfig and the public IP of the deployed service.

    To apply this Pulumi program, save it in a file (e.g., index.ts), then execute it using the Pulumi CLI:

    pulumi up

    This will provision the resources in Azure and deploy the Helm chart to your AKS cluster.
