Deploy the laravel-octane helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

Deploying the Laravel Octane Helm Chart on Digital Ocean Kubernetes Service involves several steps. Firstly, you need to set up a Kubernetes cluster on Digital Ocean. Then you can utilize the Helm Chart to deploy Laravel Octane within it.

Here's a step-by-step guide that breaks down the process:

### Step 1: Create a Kubernetes Cluster in Digital Ocean

In Pulumi, we use the DigitalOcean provider to create a Kubernetes cluster. We define the region, version, and node pool specifications for our cluster.

### Step 2: Configure Kubeconfig to Interact with the Cluster

After the cluster is created, we need to configure Kubeconfig to allow `kubectl` and other Kubernetes tools to interact with it.

### Step 3: Deploy Laravel Octane Using Helm Chart

Once we have our Kubernetes cluster ready and can interact with it, we can proceed to deploy the Laravel Octane Helm Chart. Pulumi has a Helm Chart resource type that allows us to deploy Helm charts in a Kubernetes cluster.

For this guide, I will provide you with a TypeScript-based Pulumi program that will:

- Create a Kubernetes cluster on Digital Ocean.
- Deploy the Laravel Octane Helm Chart to the cluster.

Now, let's begin the Pulumi program:

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

// Create a Digital Ocean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster('do-k8s-cluster', {
    region: 'nyc3', // Choose the appropriate region for you
    version: 'latest', // Specify the desired Kubernetes version
    nodePool: {
        name: 'default-pool',
        size: 's-2vcpu-4gb', // Choose the appropriate size for your workload
        nodeCount: 2,
    },
});

// Set up Kubeconfig to interact with the cluster
const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Use the Pulumi Kubernetes provider to interact with the Digital Ocean Kubernetes cluster
const k8sProvider = new k8s.Provider('k8sProvider', {
    kubeconfig: kubeconfig,
});

// Define the Helm chart for Laravel Octane
const laravelOctaneChart = new k8s.helm.v3.Chart('laravel-octane', {
    chart: 'laravel-octane', 
    version: 'x.y.z', // Specify the version of the Laravel Octane Helm Chart
    fetchOpts: {
        repo: 'https://helm-chart-repo-url/', // The URL of the repository where the Laravel Octane chart is hosted
    },
}, { provider: k8sProvider });

// Expose the Kubernetes cluster's kubeconfig and the Laravel Octane service endpoint
export const kubeConfigOutput = cluster.kubeConfigs[0].rawConfig;
export const laravelOctaneServiceEndpoint = laravelOctaneChart.getResourceProperty('v1/Service', 'laravel-octane', 'status').apply(s => `http://${s.loadBalancer.ingress[0].ip}`);
```

### Explanation of the Pulumi Program

- We first import the necessary Pulumi libraries for Digital Ocean and Kubernetes.
- We then initialize a `KubernetesCluster` resource from the `@pulumi/digitalocean` module. Here we define the size of the cluster, region, node pool information, and the Kubernetes version.
- We retrieve the `kubeConfig` which will be used by our Kubernetes provider to manage resources on this cluster.
- A `Provider` resource is used to set up the connection to our DigitalOcean Kubernetes cluster using the provided `kubeConfig`.
- The `Chart` resource from `@pulumi/kubernetes` represents a Helm chart. It's here that we would deploy Laravel Octane specifying its chart name, version, and repository URL. For the purpose of this example, please replace 'x.y.z' with the correct chart version and provide the appropriate Helm chart repository URL.
- Finally, we export `kubeConfigOutput` to connect to the cluster using `kubectl` and `laravelOctaneServiceEndpoint` which would be the endpoint to access Laravel Octane once it's deployed.

Please note that before running this program, you need to install the corresponding Pulumi packages for Digital Ocean and Kubernetes, which can be done using the following commands:

```sh
pulumi plugin install resource digitalocean v4.22.0
pulumi plugin install resource kubernetes v4.4.0
```

And make sure to add these dependencies to your `package.json` file too.

Replace the placeholders with actual values that reflect your needs and environment. Once you run this Pulumi program using the `pulumi up` command, it will provision a Kubernetes cluster and deploy Laravel Octane onto it.
