1. Deploy the smtp4dev helm chart on Azure Kubernetes Service (AKS)


    To deploy the smtp4dev Helm chart on Azure Kubernetes Service (AKS), we'll follow these steps:

    1. Set up an AKS cluster using Pulumi with the azure-native provider.
    2. Install the smtp4dev Helm chart on the AKS cluster using the kubernetes provider and its helm.sh/v3.Chart resource.

    Here's a step-by-step explanation of how the program will work:

    • Create an AKS Cluster: We will instantiate an AKS cluster using the azure-native package which corresponds to the ProvisionedCluster class. We provide necessary parameters such as the resource group, cluster name, location, and other cluster configurations.
    • Install Helm Chart: Once we have the AKS cluster ready, we use the kubernetes package to install the smtp4dev Helm chart. We utilize the Helm Chart resource, specify the chart's name, and optionally any values we want to override.

    The following program in TypeScript illustrates this process. Note that this assumes that you have already set up Pulumi on your machine and configured it to work with Azure.

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure"; import * as azureNative from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an AKS cluster const resourceGroup = new azureNative.resources.ResourceGroup("aksResourceGroup", { location: "East US", // Choose the appropriate region }); const aksCluster = new azureNative.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ name: "agentpool", count: 1, vmSize: "Standard_DS2_v2", // Choose the appropriate VM size }], dnsPrefix: "aksCluster", enableRBAC: true, }, { dependsOn: resourceGroup }); // Expose a K8s provider instance of the new cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: aksCluster.kubeConfigRaw, }); // Deploy smtp4dev Helm chart const smtp4devChart = new k8s.helm.v3.Chart("smtp4dev", { chart: "smtp4dev", version: "2.1.0", // Specify the chart version if needed fetchOpts: { repo: "https://helm.smtp4dev.net/", // Official Helm chart repository for smtp4dev }, }, { provider: k8sProvider }); // Export the AKS cluster kubeconfig export const kubeconfig = aksCluster.kubeConfigRaw;

    This program will create the necessary cloud resources on Azure and deploy the smtp4dev Helm chart onto the provisioned AKS cluster. The smtp4dev chart is a good choice for capturing and examining email traffic for development purposes.

    Here's a brief overview of the steps the Pulumi program will take when executed:

    1. Create an Azure Resource Group to contain our AKS cluster.
    2. Define an AKS cluster, specifying its configuration details like node quantity and size.
    3. Create a Pulumi Kubernetes provider that uses the newly created AKS cluster's kubeconfig.
    4. Deploy the smtp4dev Helm chart to the AKS cluster using the aforementioned provider.

    Finally, we export the kubeconfig of the AKS cluster, which can be used to interact with the Kubernetes cluster once it's up and running.

    To run this program, ensure you have installed Pulumi CLI and configured it with your Azure account. Save the code to a file named index.ts, and from the terminal in the same directory, run pulumi up to create the resources.
