1. Deploy the wireguard-pia helm chart on Azure Kubernetes Service (AKS)


    To deploy the WireGuard-PIA Helm chart on Azure Kubernetes Service (AKS), we will proceed with the following steps:

    1. Provision an AKS cluster using Pulumi with Azure Native Provider.
    2. Install the Helm chart onto the AKS cluster.

    Here's a detailed explanation along with the Pulumi program written in TypeScript:

    Steps and Code Explanation

    Step 1: Provisioning an AKS Cluster

    We will start by creating an AKS cluster, which requires us to define a resource group and then create the AKS cluster within that group. We will use an existing Virtual Network or create a new one, which is necessary to allocate a subnet for our AKS cluster.

    Step 2: Deploying the Helm Chart

    After the AKS cluster is provisioned, we can deploy the WireGuard-PIA Helm chart. We can do this using Pulumi's Chart resource, which is part of Pulumi Kubernetes provider. Pulumi integrates seamlessly with Helm, and this allows us to deploy Helm charts without needing to manually run helm install commands.


    Ensure you have Pulumi CLI and Azure CLI installed and properly configured to interact with your Azure account.

    Now, let's write the Pulumi program:

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provision an AKS Cluster // Create a new resource group to contain the AKS cluster and related resources const resourceGroup = new azure.resources.ResourceGroup("aksResourceGroup", { resourceGroupName: "wireguard-pia-aks-rg", location: "EastUS", // Feel free to update this to the Azure region you wish to deploy to }); // Create an AKS cluster const aksCluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceName: "aksCluster", resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ count: 2, // Set the desired count of nodes in the node pool maxPods: 110, mode: "System", name: "agentpool", osType: "Linux", vmSize: "Standard_DS2_v2", // Adjust the size as needed }], dnsPrefix: "wireguard-pia-dns", linuxProfile: { adminUsername: "azureuser", ssh: { publicKeys: [{ keyData: "ssh-rsa ..." // Replace with your SSH public key }], }, }, kubernetesVersion: "1.21.1", networkProfile: { networkPlugin: "azure", serviceCidr: "", dnsServiceIP: "", dockerBridgeCidr: "", }, enableRBAC: true, }); // Export the KubeConfig of the AKS cluster to interact with it const kubeconfig = pulumi.all([resourceGroup.name, aksCluster.name]).apply(([rgName, clusterName]) => azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }).then(creds => Buffer.from(creds.kubeconfigs[0].value, 'base64').toString()) ); export const kubeConfig = kubeconfig; // Step 2: Deploying the Helm Chart const wireguardChart = new k8s.helm.v3.Chart("wireguard-pia-chart", { chart: "wireguard-pia", // You might need to specify the repository of the Helm chart if it's not a stable one // Example: repo: "https://pia-foss.github.io/helm-charts/" values: {}, // Provide any specific configuration here fetchOpts: { // If required, provide fetch options here (e.g., to specify a version or a repository) }, }, { provider: new k8s.Provider("k8s-provider-wireguard", { kubeconfig: kubeconfig }) }); // Exporting the endpoint to access the WireGuard-PIA export const wireguardEndpoint = aksCluster.fqdn;

    In this program, we define an AKS cluster with a Linux profile including an SSH public key. We then define a default Kubernetes version and the size of the VMs within the AKS cluster's agent pool.

    The kubeconfig is then obtained from the created AKS cluster which will allow Pulumi's Kubernetes provider to deploy resources to that cluster.

    The Helm chart for WireGuard-PIA is then instantiated with the k8s.helm.v3.Chart class from Pulumi's Kubernetes provider. Depending on where the Helm chart is hosted, you may need to alter the repo property within the Chart resource; if it's not part of the standard Helm repositories, you'll need to specify the custom URL. Additionally, you can provide custom values to the chart via the values property.

    Lastly, we export the AKS cluster's FQDN so that you can interface with the WireGuard-PIA installation from outside the cluster.

    Remember to replace the placeholder values (like your SSH public key) with your actual information before running the program with Pulumi.

    To run the program:

    • Save the file as index.ts.
    • Run pulumi up in the CLI.
    • Confirm the preview looks as you expect and select yes when prompted.

    Pulumi will then handle the provisioning of the resources and the deployment of the WireGuard-PIA Helm chart to your AKS cluster.
