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

Question

Pulumi · Accepted Answer

To deploy the `laravel-helm` chart on a Digital Ocean Kubernetes service, you'll need to accomplish a few steps. This will involve setting up a DigitalOcean Kubernetes (DOKS) cluster and then using the Helm chart capabilities of Pulumi's Kubernetes provider to deploy Laravel.

Here's what we'll do step by step:
1. **Set up a DigitalOcean Kubernetes cluster**: First, we'll create a Kubernetes cluster on Digital Ocean. We'll define the cluster configuration, including region, version, and node details.
2. **Deploy the Helm chart**: Once the DOKS is ready, we'll deploy the `laravel-helm` chart to the cluster. We'll use the `Chart` resource from Pulumi's Kubernetes provider to manage the Helm release.

Below is a TypeScript program using Pulumi to deploy `laravel-helm` helm chart on Digital Ocean Kubernetes Service:

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

// Step 1: Create a new DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("laravel-cluster", {
    region: "nyc1",
    version: "latest",
    nodePool: {
        name: "default",
        size: "s-2vcpu-2gb",
        nodeCount: 2,
    },
});

// Step 2: Use the cluster's kubeconfig to interact with it
const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Create a Kubernetes provider instance that uses our DOKS cluster.
const provider = new kubernetes.Provider("doks-provider", {
    kubeconfig: kubeconfig,
});

// Step 3: Deploy the laravel-helm helm chart
const laravelChart = new kubernetes.helm.v3.Chart("laravel-helm", {
    chart: "laravel-helm",
    version: "1.0.0", // specify the version of the chart if necessary
    // Set Helm chart values here if needed, for example:
    values: {
        // ... Laravel specific helm chart values
    },
    fetchOpts: {
        repo: "https://charts.example.com/", // Replace with the actual Helm chart repository
    },
}, {
    provider: provider, // specify the provider created for the DOKS cluster
});

// Export the cluster's kubeconfig and the public IP to access Laravel.
export const kubeconfigOutput = cluster.kubeConfigs[0].rawConfig;
export const laravelEndpoint = laravelChart.getResourceProperty(
    "v1/Service", "laravel-helm", "status"
).apply(status => status.loadBalancer.ingress[0].ip);

```

Explanation of the code:

- We import the `digitalocean` and `kubernetes` modules. These provide the necessary tools to interact with DigitalOcean's Kubernetes Service and deploy Helm charts, respectively.

- We create a Kubernetes cluster using the `KubernetesCluster` resource, specifying the region, version (which fetches the latest version of Kubernetes supported by DOKS), and the configuration of the node pool.

- We obtain the kubeconfig from the created cluster, which allows us to interact with it using Kubernetes commands.

- A Kubernetes provider is created with the obtained kubeconfig, which tells Pulumi how to communicate with our DOKS cluster for deploying resources.

- The `Chart` resource from the `@pulumi/kubernetes` package is what enables us to deploy the `laravel-helm` Helm chart. The `chart` property points to the name of the chart, while `fetchOpts` contains the location of the Helm repository. If there are custom values or specific versions you need to deploy, those will be included in the `values` and `version` keys, respectively.

- Lastly, we export some key data. `kubeconfigOutput` is the kubeconfig necessary to interact with your Kubernetes cluster using tools like `kubectl`. `laravelEndpoint` will be the public IP address where you can access the Laravel application, which assumes `laravel-helm` chart provisions a Service with a LoadBalancer — this may need to be adjusted based on the actual contents of the chart.

Please ensure you have the correct Helm chart repository and the necessary configurations for your Laravel deployment. Once you plug in the correct repository for `laravel-helm`, which should provide the Laravel application configured as desired, this Pulumi program will fully provision the resources on DigitalOcean and deploy Laravel using Helm.

Remember that the provider configuration assumes you have an account token configured for the DigitalOcean provider and Pulumi CLI installed, and you're logged in to Pulumi.
