1. Deploy the stakater-buildah helm chart on Azure Kubernetes Service (AKS)


    To deploy the stakater-buildah Helm chart on Azure Kubernetes Service (AKS), you'll need to follow several steps. First, we will create an AKS cluster using Pulumi. Then, we will deploy the Helm chart to the AKS cluster. Below is a detailed explanation accompanied by the TypeScript program that accomplishes this task.

    Explanation and Pulumi Program:

    1. Create an Azure Kubernetes Service (AKS) Cluster: We'll start by creating an AKS cluster using the azure-native package, which provides native Azure resources. This will give us a managed Kubernetes cluster that we can use to deploy our applications.

    2. Deploy the stakater-buildah Helm Chart: Once the AKS cluster is up and running, we will proceed to deploy the stakater-buildah Helm chart. We'll use the kubernetes package provided by Pulumi to manage Helm charts. This package facilitates the deployment of Helm charts in a Kubernetes cluster.

    Let's begin with the Pulumi 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 the AKS cluster const resourceGroup = new azure_native.resources.ResourceGroup("aksResourceGroup", { location: "WestUS", // Replace with the location you desire }); const aksCluster = new azure_native.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 3, // Set the desired number of nodes maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: "aksk8s", // Replace with a unique DNS prefix kubernetesVersion: "1.20.7", // Set the desired Kubernetes version location: resourceGroup.location, resourceGroupName: resourceGroup.name, }, { dependsOn: resourceGroup }); // Expose the Kubernetes cluster name and kubeconfig export const clusterName = aksCluster.name; export const kubeconfig = aksCluster.kubeConfig.apply(kc => kc.raw); // Step 2: Deploy the stakater-buildah Helm Chart const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the Helm chart using the kubernetes provider we just created const helmChart = new k8s.helm.v3.Chart("stakater-buildah-chart", { chart: "stakater-buildah", version: "1.0.0", // Specify the chart version you want to deploy fetchOpts: { repo: "https://stakater.github.io/stakater-charts/", // Repository where the Helm chart is stored }, }, { provider: k8sProvider }); // Export the Helm release status export const helmReleaseStatus = helmChart.status;

    Let me walk you through what each part of the script accomplishes:

    • We start by importing the necessary Pulumi modules. The @pulumi/pulumi module is always required to run a Pulumi program. @pulumi/azure-native is used to manage resources in Azure, and @pulumi/kubernetes is used to manage Kubernetes resources, including Helm charts.

    • We define a new Azure Resource Group using azure_native.resources.ResourceGroup. This will be used to group all resources related to the AKS cluster.

    • Next, we create the AKS cluster using azure_native.containerservice.ManagedCluster. Here, you define the node count, VM size, OS type, and other configurations for your AKS cluster.

    • We then declare two exports: clusterName and kubeconfig. kubeconfig is required to interact with your AKS cluster and will be used by the Kubernetes provider to deploy the Helm chart.

    • We create a new instance of the k8s.Provider which tells Pulumi how to communicate with our AKS cluster. It utilizes the kubeconfig we obtained from the AKS cluster creation.

    • Finally, we deploy the Helm chart using k8s.helm.v3.Chart. We provide the name of the chart, the version, and the repository URL where the chart can be found.

    • We also export the helmReleaseStatus to see the status of the Helm chart deployment.

    With this Pulumi program, you can deploy the stakater-buildah Helm chart to your Azure Kubernetes Service cluster. Please ensure you have the Azure CLI or Pulumi Azure credentials set up for authentication before running this program.

    Deploying applications with Helm charts on Kubernetes using Pulumi is reliable and straightforward, abstracting away much of the complexity involved in managing cloud resources.
