Deploy the influxdb-enterprise helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the InfluxDB Enterprise Helm chart on Azure Kubernetes Service (AKS), you'll need to perform a sequence of steps using Pulumi. This process involves setting up the necessary infrastructure on Azure, which includes creating an AKS cluster.

Below is a step-by-step guide along with the Pulumi TypeScript code to achieve this.

1. **Set up an AKS Cluster**: The `azure-native.containerservice.KubernetesCluster` resource will be used to provision an AKS cluster. This creates a managed Kubernetes cluster in Azure.

2. **Install the Helm Chart for InfluxDB Enterprise**: Pulumi's `helm.v3.Chart` resource will be used to deploy the InfluxDB Enterprise chart onto the AKS cluster.

3. **Define the Required Resources and Deploy**: After defining these resources in our Pulumi program, we will deploy them. Pulumi ensures these resources are created in the correct order of dependencies.

Make sure you have the following prerequisites:

- Pulumi CLI installed
- Azure CLI installed and configured with your Azure account
- Node.js and npm installed

Now, let's proceed with the Pulumi program.

```typescript
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";
import * as helm from "@pulumi/kubernetes/helm";

// Create an Azure Resource Group
const resourceGroup = new azureNative.resources.ResourceGroup("myResourceGroup", {
    resourceGroupName: "myResourceGroup",
    location: "WestUS", // Select an appropriate Azure location
});

// Create an AKS cluster
const aksCluster = new azureNative.containerservice.KubernetesCluster("myAKSCluster", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    kubernetesVersion: "1.18.14", // Use a supported Kubernetes version
    identity: {
        type: "SystemAssigned",
    },
    defaultNodePool: {
        name: "default",
        nodeCount: 2, // Specify the desired node count
        vmSize: "Standard_DS2_v2", // Select an appropriate VM size
    },
    dnsPrefix: `${pulumi.getStack()}-kube`, // A DNS prefix unique across Azure
});

// Export the AKS cluster kubeconfig
export const kubeconfig = pulumi.all([aksCluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => {
    return azure.containerservice.getKubernetesCluster({
        name: clusterName,
        resourceGroupName: rgName,
    }).kubeConfigRaw;
});

// Create a Kubernetes provider instance using the kubeconfig
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: kubeconfig,
});

// Deploy the InfluxDB Enterprise Helm chart onto the AKS cluster
const influxdbChart = new helm.v3.Chart("influxdb-enterprise", {
    chart: "influxdb-enterprise",
    version: "1.0.0", // Replace with a specific chart version if needed
    fetchOpts: {
        repo: "https://helm.influxdata.com/", // InfluxDB Helm repository URL
    },
}, { provider: k8sProvider });

// Export the cluster services
export const influxdbService = influxdbChart.getResource("v1/Service", "influxdb-enterprise-influxdb");

// Note: You might need to configure other InfluxDB Enterprise Helm chart values based on your requirements.
```

After defining this code in a `.ts` file (for example, `index.ts`), you should run `pulumi up` to deploy your Pulumi stack. Pulumi will handle provisioning the resources in the correct order and connect the Kubernetes resources with the AKS cluster.

It is important to review the Helm chart values and adjust them to your needs. The placeholder values in `version` and other chart parameters need to be set according to the version of InfluxDB Enterprise Helm chart you intend to deploy and your specific configuration needs.

Additionally, remember that using InfluxDB Enterprise may require a valid license, so ensure you have all the necessary terms and licenses agreed before deploying it on the AKS cluster.
