Using azure-native insights with kubernetesconfiguration

Question

Pulumi · Accepted Answer

To use Azure Native insights with Kubernetes configuration, you typically want to monitor the performance of Kubernetes applications and ensure that configuration changes within your Kubernetes clusters are tracked effectively. Azure Monitor provides various tools to achieve this, including Application Insights for monitoring performance, and Azure Kubernetes Configuration to manage and track configurations.

In Pulumi, Azure Native is a package that you can use to operate Azure resources idiomatically. You can use `azure-native.insights` to create and configure Application Insights instances, which can monitor your applications running in AKS (Azure Kubernetes Service). Additionally, `azure-native.kubernetesconfiguration` contains resources for managing Kubernetes configurations, such as applying extensions to expand the capabilities of your Kubernetes clusters hosted in Azure.

Here's how you might configure an Application Insights instance and a Kubernetes Configuration extension using Pulumi with TypeScript:

First, we’ll need to import the necessary Pulumi and Azure Native packages in our TypeScript program. Then we'll create an Application Insights instance to monitor our app. We'll also add a Kubernetes Configuration to apply an extension to our AKS cluster. We're assuming that you've already set up an AKS cluster and have its details ready to use.

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as insights from "@pulumi/azure-native/insights";
import * as k8sconfiguration from "@pulumi/azure-native/kubernetesconfiguration";

// Create an Application Insights instance for the AKS cluster
const appInsights = new insights.Component("myAppInsights", {
    resourceGroupName: "myResourceGroup",
    kind: "k8s", // Indicating that it's for monitoring Kubernetes
    applicationType: "web", // Application type, in this case a web application
    location: "East US", // Replace with the location of your resources
});

// Define an Extension for the AKS cluster
const aksExtension = new k8sconfiguration.Extension("myAksExtension", {
    extensionType: "Microsoft.ApplicationInsights.AzureMonitor", // The type of extension to install
    clusterName: "myAksCluster", // The name of your AKS cluster
    clusterRp: "Microsoft.ContainerService", // The Resource Provider for AKS
    scope: {
        cluster: { 
            releaseNamespace: "default" // The namespace where the extension will be released
        },
    },
    plan: {
        name: "myAppInsightsExtensionPlan",
        product: "appid", // Replace with valid product details for your add-on
        publisher: "Microsoft",
    },
    resourceGroupName: "myResourceGroup",
});

// Optionally, export the Application Insights instrumentation key
export const instrumentationKey = appInsights.instrumentationKey;
```

In the above code:

- We create an Application Insights instance with `insights.Component`. This is where you'll monitor the performance and usage of your Kubernetes-hosted applications.
- We use `k8sconfiguration.Extension` to apply an extension to the AKS cluster for Azure Monitor, which facilitates the integration with Application Insights.
- Finally, we export the `instrumentationKey` from Application Insights, which you can use to configure your application's telemetry SDK so that it sends data to the correct Application Insights resource.

You'll need to replace placeholder strings like "myResourceGroup" and "myAksCluster" with the names of your actual Azure resource group and AKS cluster. Likewise, configure the `plan` with valid product details for the Azure Monitor add-on you wish to apply.

To run this program, you'll need to have Pulumi installed and configured for use with Azure. You would save this code in a file, such as `index.ts`, and then deploy it using the Pulumi CLI with commands `pulumi up`.

Remember that you need to ensure that you have the Azure CLI installed and configured and that you are logged in to an Azure account with the necessary permissions to create these resources.
