Deploy the prometheus-freebox-exporter helm chart on Azure Kubernetes Service (AKS)
TypeScriptTo deploy the
prometheus-freebox-exporter
helm chart on Azure Kubernetes Service (AKS), we are going to take the following steps:- Set up an AKS cluster using Pulumi's Azure Native provider.
- Install the Helm Chart by creating a Pulumi resource which deploys Helm charts into a Kubernetes cluster.
Ensure you have an Azure account with the necessary permissions to create resources, and the Pulumi CLI installed and configured for Azure.
Now, let’s break down the necessary steps within our Pulumi program:
Step 1: Create an AKS Cluster
We will define an AKS cluster resource. The AKS cluster will serve as the environment where the
prometheus-freebox-exporter
will be deployed. The resource properties define the cluster size, version, node count, and other essential configurations.Step 2: Install Helm Chart
Once the cluster is running, we can deploy the
prometheus-freebox-exporter
helm chart. Pulumi's support for Helm charts comes through the@pulumi/kubernetes
package, which provides a resource type for Helm charts. We will use the necessary Helm Chart values to configure theprometheus-freebox-exporter
.The Pulumi Program (TypeScript)
import * as pulumi from '@pulumi/pulumi'; import * as azure_native from '@pulumi/azure-native'; import * as k8s from '@pulumi/kubernetes'; // Create an AKS cluster const cluster = new azure_native.containerservice.ManagedCluster("myAksCluster", { // Set necessary parameters according to your needs resourceGroupName: "myResourceGroup", agentPoolProfiles: [{ count: 1, maxPods: 110, mode: "System", name: "agentpool", nodeLabels: {}, osDiskSizeGB: 30, osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: "myakscluster", kubernetesVersion: "1.20.9", }); // Export the kubeconfig export const kubeconfig = cluster.kubeConfig; // Create a Kubernetes provider instance with the kubeconfig from the AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfig.apply(JSON.stringify), }); // Install the `prometheus-freebox-exporter` using a Helm Chart const freeboxExporterChart = new k8s.helm.v3.Chart("freebox-exporter", { // Define Chart values here, like the repository URL and chart version chart: "prometheus-freebox-exporter", version: "1.0.0", // specify the exact chart version fetchOpts: { repo: "http://helm-repo-path", // replace with the Helm repository URL }, }, { provider: k8sProvider }); // Export the Chart status export const helmChartStatus = freeboxExporterChart.status;
This code defines an AKS cluster and then uses the resulting kubeconfig to create a Pulumi Kubernetes provider. This provider is then used to install a Helm chart.
Make sure to replace
"myResourceGroup"
with the name of the resource group where you want to create the AKS cluster. You will also need to provide the exact Helm repo path where theprometheus-freebox-exporter
chart is located by replacing"http://helm-repo-path"
.Ensure you have the correct Helm chart version; if you don't, you can omit the version parameter to use the latest one.
Running this program with Pulumi will provision an AKS cluster and deploy the Prometheus Freebox Exporter within that cluster. To run the program, invoke the Pulumi CLI:
pulumi up
This command will show you a preview of the resources that will be created and, upon confirmation, will proceed to apply the changes. When the deployment is successful, the Pulumi program will print the exported values, such as
kubeconfig
andhelmChartStatus
, in the console. You can use the providedkubeconfig
to access your Kubernetes cluster usingkubectl
.
