Deploy the phpstorm helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the PhpStorm Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you'll need to first set up a Kubernetes cluster on DigitalOcean. Then, you can deploy the Helm chart to that cluster.

Below, you'll find a Pulumi program written in TypeScript that accomplishes this task. The program is divided into two main parts:
1. Provisioning a Kubernetes cluster on DigitalOcean.
2. Deploying the PhpStorm Helm chart to the cluster.

Before running the program, make sure you have the Pulumi CLI installed and configured for use with DigitalOcean. You will also need to have `kubectl` installed to interact with the cluster, as well as Helm tooling if you want to manage Helm releases manually.

Here's the TypeScript program for deploying the PhpStorm Helm chart on a DigitalOcean Kubernetes cluster:

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

// Step 1: Provision a DigitalOcean Kubernetes cluster.
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc3", // Replace with your desired region
    version: "latest", // Use the latest Kubernetes version or specify a version
    nodePool: {
        name: "default",
        size: "s-2vcpu-2gb", // Choose the size that fits your needs
        nodeCount: 2, // Specify the desired number of nodes in the node pool
    },
});

// Step 2: Deploy the PhpStorm Helm chart to the cluster.
const phpstormChart = new k8s.helm.v3.Chart("phpstorm-chart", {
    chart: "phpstorm",
    version: "1.0.0", // Specify the version of the chart you want to deploy
    fetchOpts:{
        repo: "https://charts.example.com/", // Specify the Helm chart repository URL
    },
}, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) });

// Export the cluster's kubeconfig and the service's public IP (if applicable).
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
export const servicePublicIP = phpstormChart.getResourceProperty("v1/Service", "phpstorm-service", "status")
    .apply(status => status.loadBalancer?.ingress[0]?.ip);

```

Here's a detailed explanation of the components of this code:

1. We first import the necessary packages for Pulumi, the DigitalOcean provider, and Kubernetes.

2. In the digitalocean namespace, we create a new Kubernetes cluster (`digitalocean.KubernetesCluster`). We customize this cluster by specifying the region to deploy in, the version of Kubernetes to use, and details about the node pool such as the number of nodes and droplet size.

3. Next, we deploy the PhpStorm Helm chart using the `k8s.helm.v3.Chart` resource from the Pulumi Kubernetes provider. In this chart configuration, you need to specify the name of the chart and the version. Since Helm charts usually come from a chart repository, you would also need to specify the repository URL where the PhpStorm Helm chart is located (in the `fetchOpts.repo` field). Since PhpStorm is an IDE by JetBrains and not known to be offered as a Helm chart, you would have to replace `'phpstorm'` and the repo URL with the appropriate ones for your actual use case.

4. We create a Kubernetes provider instance that uses the kubeconfig of the newly created cluster so that the Helm chart can be deployed in it.

5. Finally, we export the kubeconfig of the cluster and potentially the public IP address of the service that the Helm chart deploys, if it contains a Service resource with type LoadBalancer. This allows you to interact with the Kubernetes cluster using `kubectl` and access the deployed PhpStorm instance (or whichever application is actually being deployed by the Helm chart).

To deploy this code with Pulumi, save it to a file with a `.ts` extension (e.g., `index.ts`), and then run `pulumi up` in the same directory. Pulumi will automatically detect the file, compile the TypeScript program into JavaScript, and then execute it to deploy your infrastructure.
