1. Deploy the weird helm chart on Azure Kubernetes Service (AKS)


    To deploy a Helm chart onto an Azure Kubernetes Service (AKS) cluster using Pulumi, you'll need to orchestrate several steps: create the AKS cluster, install the necessary dependencies for Helm, and finally deploy the chart itself.

    Here's how you can do that with Pulumi using TypeScript.

    1. Define your AKS Cluster: You'll start by authoring a Pulumi program to provision your AKS cluster. For this scenario, I'll use the azure-native provider as it directly interacts with Azure resources.

    2. Install the Helm Chart: Once your AKS cluster is set up, you'll want to install a Helm chart into it. For that, you'll use the kubernetes provider to interact with Kubernetes.

    3. Deploy the Helm Chart: Finally, you'll define the Chart resource that represents your "weird" Helm chart. Pulumi can pull Helm charts from any chart repository, or from a local path if your chart is hosted there.

    I will now show you the code on how to do this. Each step will have comments to guide you through the process.

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Define the AKS cluster. const resourceName = "myAKSCluster"; // Change with your desired resource name const resourceGroupName = new azure.resources.ResourceGroup(resourceName); const cluster = new azure.containerservice.ManagedCluster(resourceName, { resourceGroupName: resourceGroupName.name, agentPoolProfiles: [{ count: 1, maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: resourceName, enableRBAC: true, kubernetesVersion: "1.19.11", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCe /....== Generated by Azure", // replace with your public SSH key }], }, }, nodeResourceGroup: `MC_${resourceName}`, }); // Export the kubeconfig - this allows us to interact with the cluster programmatically export const kubeconfig = pulumi. all([cluster.name, resourceGroupName.name]). apply(([clusterName, rgName]) => { let creds = azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); return creds.kubeconfigs[0].value.apply(enc => Buffer.from(enc, 'base64').toString()); }); // Step 2: Configure the Kubernetes provider using the kubeconfig from the AKS cluster created above. const k8sProvider = new k8s.Provider(resourceName, { kubeconfig: kubeconfig, }); // Step 3: Deploy the Helm chart into AKS. const chart = new k8s.helm.v3.Chart("myWeirdChart", { chart: "weirdChartName", // Replace with the real chart name version: "1.0.0", // Specify the chart version fetchOpts: { repo: "http://myhelmrepo.com/" // Replace this with your Helm chart's repository URL }, }, { provider: k8sProvider }); // Export the resulting base URL this will be the URL to access deployed services export const baseUrl = chart.getResourceProperty("v1/Service", "myWeirdChart-svc", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In this code, the ManagedCluster resource from the azure-native provider creates an AKS cluster. We configure the Kubernetes provider using the kubeconfig obtained from the AKS cluster to interact with our Kubernetes resources.

    Next, we define a Chart resource, which tells Pulumi to deploy the specified Helm chart weirdChartName into the AKS cluster we just created. Replace weirdChartName with the name of your chart, and the repo URL with the location of your Helm repository.

    The last line of code exports a baseUrl, which assumes your Helm chart provisions a service of type LoadBalancer with an external IP; this will be the IP to access your deployed services.

    To apply this Pulumi program:

    1. Save this code in a file such as index.ts.
    2. Ensure you've installed Pulumi and logged in to your account.
    3. Set up your Azure credentials.
    4. Run the following commands:
    pulumi stack init dev pulumi up

    When the pulumi up command completes, you'll have an AKS cluster with your Helm chart deployed to it. Pulumi provides outputs after the deployment, including the baseUrl if applicable to your Helm chart.
