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


    To deploy the FRP (Fast Reverse Proxy) Server Helm chart on an Azure Kubernetes Service (AKS) cluster, we'll follow these steps:

    1. Construct an Azure Kubernetes Service (AKS) cluster where our Helm chart will be deployed.
    2. Deploy the FRP Server Helm chart into the created AKS cluster.

    For both of these steps, we'll be using Pulumi's Infrastructure as Code (IaC) approach. Pulumi allows us to define our infrastructure using familiar programming languages such as TypeScript.

    Here's what we need to get started:

    • An Azure subscription: You need to have an Azure subscription to create resources on Azure.
    • Pulumi CLI installed: This tool manages Pulumi stacks and performs operations like previewing, updating, and destroying cloud resources. You can get it from the Pulumi installation guide.
    • Azure CLI installed: This is used to log in to your Azure account. It can be installed from the Azure CLI installation page.
    • An initialized Pulumi project: If you haven't created one, you can start with pulumi new azure-typescript.

    Now, let's start by defining an AKS cluster using Pulumi, and then deploy the FRP Server Helm chart into this cluster. I'll include comments to explain each section of the code.

    TypeScript Program for Deploying FRPS Helm Chart on AKS

    import * as azure from "@pulumi/azure"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create an AKS cluster. const aksCluster = new azure.containerservice.KubernetesCluster("aksCluster", { // Define the resource group where the AKS cluster will reside. resourceGroupName: azure.core.getResourceGroup().name, // Specify the version of Kubernetes to use for the AKS cluster. kubernetesVersion: "1.18.14", // Define the default node pool for the AKS cluster. defaultNodePool: { name: "default", nodeCount: 2, vmSize: "Standard_DS2_v2", }, // Enable RBAC for secure interaction with the cluster. roleBasedAccessControl: { enabled: true }, // Define the service principal used by the AKS cluster. // It's recommended to use a service principal specific to the AKS cluster. servicePrincipal: { clientId: "REPLACE_WITH_CLIENT_ID", clientSecret: "REPLACE_WITH_CLIENT_SECRET", } }); // Output the generated Kubeconfig file for the AKS cluster. export const kubeconfig = aksCluster.kubeConfigRaw; // Define the FRP Server Helm chart. const frpsChart = new kubernetes.helm.v3.Chart("frps", { chart: "frp", // Specify the version of the Helm chart to use. version: "1.0.0", // Assign the Helm chart to the existing AKS namespace. // If the namespace doesn't exist, Helm will create it. namespace: "frp-namespace", // Pass the desired values for configuring the Helm chart. values: { // Define the values required by the FRP Server Helm chart here. // Example: service type being LoadBalancer for exposing it publicly. service: { type: "LoadBalancer", }, }, }, { provider: new kubernetes.Provider("k8sProvider", { kubeconfig: aksCluster.kubeConfigRaw }) }); // Export the public IP address of the FRP server load balancer, if available. export const frpsPublicIP = frpsChart.getResourceProperty("v1/Service", "frps", "status") .apply(status => status.loadBalancer.ingress[0].ip);

    Before you run this program, make sure to replace REPLACE_WITH_CLIENT_ID and REPLACE_WITH_CLIENT_SECRET with the Azure AD application client ID and secret.

    After setting up the above code within your Pulumi project:

    1. Run the pulumi up command to preview and deploy the resources.
    2. Once the deployment is successful, Pulumi will output the kubeconfig and frpsPublicIP if the service load balancer receives a public IP.
    3. You can use the kubeconfig to interact with your AKS cluster using kubectl.

    Here, we've used azure.containerservice.KubernetesCluster to create a managed Kubernetes cluster on Azure. Then, we used kubernetes.helm.v3.Chart to deploy the FRP Server Helm chart. We're also using kubeconfig to provide our Kubernetes Provider with the necessary credentials to interact with our AKS cluster.

    If you need more detailed information about the Pulumi Azure provider, you can visit the Azure Containerservice documentation. For more information on using Helm charts with Pulumi, you can refer to the Pulumi Helm Chart documentation.
