Deploy the phpstorm helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

Deploying an application with Helm on Azure Kubernetes Service (AKS) involves several steps, including setting up the AKS cluster, configuring Helm, and deploying the chart. I'll guide you through this process using Pulumi to automate your infrastructure.

### Pulumi Configuration

First, ensure you have Pulumi installed and configured on your local machine to work with your Azure account. You need to log in to Azure CLI and set your subscription.

### AKS Cluster Creation

Let's begin by setting up an AKS cluster where your Helm chart for Phpstorm will be deployed. The cluster will provide the necessary Kubernetes environment.

In this program, we will use the `azure-native` package because it provides native Azure support and is the recommended choice for new projects.

Here's what the code doing just the AKS cluster setup would look like in TypeScript:

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

// Create an Azure Resource Group
const resourceGroup = new azure.resources.ResourceGroup("my-resource-group");

// Create an AKS cluster
const cluster = new azure.containerservice.ManagedCluster("my-aks-cluster", {
    resourceGroupName: resourceGroup.name,
    agentPoolProfiles: [{
        count: 2,
        maxPods: 110,
        mode: "System",
        name: "agentpool",
        osType: "Linux",
        vmSize: "Standard_DS2_v2",
    }],
    dnsPrefix: "myakscluster",
    enableRBAC: true,
    kubernetesVersion: "1.18.14",
});

// Export the Kubernetes config
export const kubeconfig = cluster.kubeConfig;
```

In this example, we're setting up an AKS cluster with an agent pool that has 2 VMs of the size `Standard_DS2_v2`. RBAC is enabled for added security, and we're using Kubernetes version `1.18.14`.

### Deploying Helm Chart to AKS

The second part involves installing the Phpstorm Helm chart. Before you run this code, you'll need to have Helm installed on your machine.

Here's the Pulumi code to deploy a Helm chart onto the AKS cluster:

```typescript
import * as k8s from "@pulumi/kubernetes";
import * as pulumi from "@pulumi/pulumi";

// Create a Kubernetes provider instance that uses our cluster from above.
const provider = new k8s.Provider("aks-k8s", {
    kubeconfig: cluster.kubeConfigRaw,
});

// Deploy the Phpstorm Helm chart into the cluster
const phpstormChart = new k8s.helm.v3.Chart("phpstorm", {
    chart: "phpstorm",
    version: "x.y.z", // replace with the desired chart version
    // You typically obtain repository and additional fields from the chart definition
    // which you want to deploy.
    repositoryOpts: {
        repo: "https://charts.bitnami.com/bitnami",
    },
    // If any, specify the values file configuration
    values: {
        // Replace with appropriate configuration for phpstorm chart
    },
}, { provider });

// Export any of the resources' properties you might want to view
export const phpstormChartStatus = phpstormChart.status;
```

### Steps to Run and Access

1. Save the complete code into a file named `index.ts`.
2. Run `pulumi up` to preview and deploy the changes.
3. After deployment, the Kubernetes configuration needed to access the cluster programmatically is exported.
4. Access your AKS cluster using kubectl and the output kubeconfig from the Pulumi stack.

Remember to replace the `x.y.z` with the actual version of the Phpstorm Helm chart you wish to deploy, and configure the `values` with the settings appropriate for your chart.

This code sets up a Kubernetes provider to interact with the previously created AKS cluster, then defines a new Helm chart resource specifying the chart name, version, and any additional configuration parameters. Once the Pulumi program is applied with `pulumi up`, it will deploy the specified version of the Phpstorm Helm chart onto the AKS cluster.

### Notes

- Ensure that the `phpstorm` chart exists at your specified repository. The example uses a placeholder repository `https://charts.bitnami.com/bitnami`, which you'll have to replace with the actual repository URL if different.
- As Helm charts may need specific configuration values, you should replace the `values` in the `phpstormChart` resource with the appropriate configuration options for the Phpstorm Helm chart.
- Adapt the AKS cluster specifications to suit your use-case requirements (e.g., node count, vmSize, Kubernetes version, etc.).
- `kubeconfig` is exported to allow `kubectl` to interact with the cluster directly. It's sensitive data and should be handled securely.

After deploying this Pulumi program, your Phpstorm application should be running on AKS, and you can manage it using Kubernetes tooling.
