1. Deploy the linkerd-edge-mixin helm chart on Azure Kubernetes Service (AKS)


    To deploy the linkerd-edge-mixin Helm chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, we will follow these steps:

    1. Set up an AKS cluster: Before deploying any applications, you need an AKS cluster. An AKS cluster gives you a managed Kubernetes cluster in Azure that you don't need to maintain or update manually. You can provision an AKS cluster using Pulumi's azure-native.containerservice.ManagedCluster resource.

    2. Deploy the Helm chart: With the cluster set up, you can deploy Helm charts to the cluster. Pulumi provides the kubernetes.helm.v3.Chart resource to streamline this process. You will need to point to the Helm repository that hosts your linkerd-edge-mixin chart and specify any configuration values required by the chart.

    Below is a TypeScript program that accomplishes these tasks. This program assumes you have already configured Pulumi with your Azure credentials.

    import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create an AKS cluster const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup"); const cluster = new azure.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, // Required properties (like location) are typically specified in the config, // but you can hardcode them as well in the code. location: resourceGroup.location, agentPoolProfiles: [{ count: 1, vmSize: "Standard_B2s", name: "agentpool" // Name for the node pool }], dnsPrefix: "myakscluster" // Replace with a prefix you prefer or generate a unique one }); // Export the kubeconfig for the cluster export const kubeconfig = pulumi. all([cluster.name, resourceGroup.name]). apply(([clusterName, resourceGroupName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: resourceGroupName, resourceName: clusterName, }); }). apply(creds => Buffer.from(creds.kubeconfigs[0].value, "base64").toString()); const k8sProvider = new k8s.Provider("k8s", { kubeconfig }); // Step 2: Deploy the linkerd-edge-mixin Helm chart const linkerdChart = new k8s.helm.v3.Chart("linkerd-edge-mixin", { chart: "linkerd-edge-mixin", version: "latest", // Specify the version, or use "latest" if you want the latest version fetchOpts: { repo: "https://helm.linkerd.io/edge", // URL of the linkerd-edge Helm repository }, }, { provider: k8sProvider }); // Export the endpoint of the AKS cluster export const aksClusterEndpoint = cluster.privateFqdn;

    This program will do the following:

    • Create a new resource group in Azure to host all our resources.
    • Provision a new AKS cluster inside this resource group. We've specified a single node pool with one node for simplicity.
      • Note other required properties such as location and dnsPrefix are either specified directly or can be provided through Pulumi config. For a production-grade cluster, you'll likely need additional configurations (like multiple node pools, network policies, etc.).
    • Retrieve and export the kubeconfig file, allowing you to interact with the cluster using kubectl or other Kubernetes tools.
    • Initialize a Pulumi Kubernetes provider using the kubeconfig.
    • Deploy the linkerd-edge-mixin Helm chart to the AKS cluster using the Kubernetes provider.

    Remember to replace some of the values (e.g., dnsPrefix) with your own preferred values or auto-generate them as necessary. Additionally, if the Helm chart linkerd-edge-mixin requires it, you can supply custom configuration values within the values field of the Chart resource.

    After running pulumi up to apply this Pulumi program, the infrastructure will be set up, and the linkerd-edge-mixin chart will be deployed to your AKS cluster. You can manage and monitor your Kubernetes resources through the Azure portal or using Kubernetes tooling like kubectl.
