1. Deploy the haproxytech-haproxy-ingress helm chart on Azure Kubernetes Service (AKS)


    To deploy the haproxytech-haproxy-ingress Helm chart on Azure Kubernetes Service (AKS), we'll follow these steps:

    1. Set up the Azure Kubernetes Service (AKS) cluster.
    2. Configure the Kubernetes provider to use the credentials from the AKS cluster.
    3. Deploy the haproxytech-haproxy-ingress Helm chart to the AKS cluster.

    First, you'll need to have the Pulumi CLI installed and configured with an appropriate Azure account.

    Step 1: Set Up AKS Cluster

    We'll define an AKS cluster using the azure-native provider, which allows us to create Azure resources using Pulumi. Here's why we're using specific resources:

    • ResourceGroup: A container that holds related resources for an Azure solution.
    • ManagedCluster: The AKS cluster resource.

    The ResourceGroup will group the cluster and related resources together, while the ManagedCluster will actually create the AKS cluster.

    Step 2: Configure Kubernetes Provider

    After creating the AKS cluster, we will extract the kubeconfig from the created cluster. This kubeconfig allows us to interact with the AKS cluster using Kubernetes commands, and we will use it to configure the Pulumi Kubernetes provider.

    Step 3: Deploy Helm Chart

    We will deploy the haproxytech-haproxy-ingress Helm chart using Pulumi's Chart resource from the kubernetes package. The Chart resource is used to deploy packaged applications to a Kubernetes cluster.

    Comments within the program will guide you through what each part of the script is doing. Below is the TypeScript program:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an Azure Resource Group const resourceGroup = new azure_native.resources.ResourceGroup("resourceGroup"); // Step 2: Create an AKS Cluster const cluster = new azure_native.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, // Number of agents (VMs) to host k8s workloads maxPods: 110, // Maximum number of pods that can run on an agent mode: "System", osType: "Linux", vmSize: "Standard_DS2_v2", // VM type for the agents name: "agentpool", // Name of the agent pool }], dnsPrefix: "aksk8s", // DNS prefix for the AKS cluster enableRBAC: true, // Enable Kubernetes RBAC kubernetesVersion: "1.20.7", // Specify the version of Kubernetes linuxProfile: { // Configuration for Linux VMs adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "ssh-rsa AAAAB3NzaC1..." }], }, }, }); // Export the AKS cluster kubeconfig. export const kubeconfig = pulumi. all([cluster.name, resourceGroup.name]). apply(([clusterName, rgName]) => { return azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); }).apply(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()); // Step 3: Configure the Kubernetes provider with the obtained kubeconfig const provider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Step 4: Deploy the `haproxytech-haproxy-ingress` Helm chart const haproxyIngress = new k8s.helm.v3.Chart("haproxy-ingress", { chart: "haproxy-ingress", fetchOpts: { repo: "https://haproxytech.github.io/helm-charts", }, version: "1.17.1", // Specify the chart version you wish to deploy }, { provider: provider }); // Export the ingress IP to access the ingress controller from the internet export const ingressIp = haproxyIngress.getResourceProperty("v1/Service", "haproxy-ingress-controller", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In this program, be sure to replace the placeholder in the ssh keyData with your actual public SSH key.

    After setting up this program, run these commands to deploy your infrastructure:

    pulumi up # Preview and deploy changes pulumi stack # View stack outputs (includes ingress IP) pulumi destroy # Tear down all resources

    These commands will initiate the Pulumi deployment process, which provisions resources on Azure. The ingress IP output is useful to access the HAProxy ingress controller from the internet once it's deployed.
