1. Deploy the jx-app-cert-manager helm chart on Azure Kubernetes Service (AKS)

    TypeScript

    To deploy the jx-app-cert-manager Helm chart on Azure Kubernetes Service (AKS), you would need to perform the following steps:

    1. Set up an AKS cluster: Before you can deploy any applications to AKS, you need to have a cluster up and running.

    2. Install and configure Helm on your local machine: Helm is a package manager for Kubernetes, which simplifies the process of managing Kubernetes applications. Helm uses charts, which are packages of pre-configured Kubernetes resources.

    3. Add the repository containing the jx-app-cert-manager chart: You need to add the Helm repository that contains the jx-app-cert-manager chart to your Helm configuration.

    4. Install the jx-app-cert-manager chart: After adding the repository, you can install the chart into your AKS cluster.

    Here, I’ll show you how to write a Pulumi program that accomplishes the first and last steps of this process. As the necessary information to directly integrate jx-app-cert-manager is not available in the Pulumi Registry provided, I'll demonstrate how to create an AKS cluster and deploy a generic Helm chart, which can be adapted to jx-app-cert-manager.

    First, I’ll define an AKS cluster using Pulumi's azure-native provider. Then I’ll deploy a Helm chart to the AKS cluster using Pulumi's kubernetes-cert-manager provider, which provides capabilities to manage Cert Manager on Kubernetes through Helm. In this example, I'll generalize the usage, which you would need to adapt for the specific jx-app-cert-manager Helm chart by using the correct chart name and repository URL.

    Let's start with creating a Pulumi program using TypeScript:

    import * as azure from "@pulumi/azure-native"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as kx from "@pulumi/kubernetesx"; // Define a name for the AKS cluster const name = "my-aks-cluster"; // Create an Azure Resource Group const resourceGroup = new azure.resources.ResourceGroup("resourceGroup", { resourceGroupName: name, }); // Create an AKS cluster const cluster = new azure.containerservice.ManagedCluster("cluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", nodeLabels: {}, osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: name, kubernetesVersion: "1.19.7", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "<SSH PUBLIC KEY>", }], }, }, nodeResourceGroup: `MC_${name}`, }); // Export the kubeconfig of the AKS cluster export const kubeconfig = cluster.kubeConfigRaw; // A Pulumi program to deploy a Helm chart into AKS once it's available const myChart = new k8s.helm.v3.Chart("my-cert-manager-chart", { chart: "cert-manager", version: "1.0.4", // specify your desired chart version here fetchOpts: { repo: "https://charts.jetstack.io", // specify the chart repository URL here }, // Add any additional configuration for Helm chart here values: { // Values to pass to the helm chart }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig }) }); // Export the endpoint for the Kubernetes service export const endpoint = cluster.fqdn;

    Explanation:

    1. We import the required Pulumi packages.
    2. We define some configuration for our AKS cluster, such as node pool settings, VM sizes, and the SSH key for cluster access.
    3. We create a new Azure resource group and then create a Managed Kubernetes Cluster (AKS) within this resource group.
    4. We export the raw kubeconfig of the cluster so that we can interact with it using kubectl or a Kubernetes client.
    5. We define a Helm Chart resource for deploying cert-manager, which would be similar to jx-app-cert-manager. Here, you'd adjust the chart and repo properties to match the correct chart name and Helm repository URL for jx-app-cert-manager.

    To adjust the example for the specific jx-app-cert-manager chart you would like to deploy, you need to change the chart and repo fields in the Helm Chart resource to point to the correct chart and repository.

    Replace <SSH PUBLIC KEY> with your actual SSH public key to allow secure SSH access to the nodes of the AKS cluster.

    Please note that for deploying Helm charts, usually you would interact with Helm directly from your local machine or an automated pipeline. Pulumi is capable of automating this process, as well, but the usual setup process of Helm must also be in place or managed via Pulumi.

    After you write your Pulumi program, you would run it using the Pulumi CLI, which would handle the creation of the cloud resources defined in the program.
