Deploy the laravel-helm helm chart on AWS EKS

Question

Pulumi · Accepted Answer

In order to deploy the Laravel Helm chart on AWS Elastic Kubernetes Service (EKS), we will perform the following steps:

1. Create an AWS EKS Cluster to provide the Kubernetes environment.
2. Deploy the Laravel Helm chart into the EKS cluster.

For the EKS cluster, we'll use the `eks.Cluster` class from the Pulumi EKS package, which simplifies creating an EKS cluster. Then, we'll deploy the Laravel Helm chart using the `kubernetes.helm.v3.Chart` class from the Pulumi Kubernetes package.

Let's go through the code for each part:

```typescript
import * as eks from "@pulumi/eks"; // High-level EKS component to create clusters
import * as kubernetes from "@pulumi/kubernetes"; // Used to interact with Kubernetes resources
import * as pulumi from "@pulumi/pulumi"; // Core Pulumi SDK

// Step 1: Create an EKS cluster
const cluster = new eks.Cluster("eks-cluster", {
    // Define the desired Kubernetes version; this example uses version 1.21
    version: "1.21",
    // Define other configurations like VPC, number of nodes, etc. Here, we use default settings
});

// Export the cluster details
export const kubeconfig = cluster.kubeconfig; // Export kubeconfig to interact with the cluster

// Step 2: Deploy the Laravel Helm chart into the EKS cluster
const laravelHelmChart = new kubernetes.helm.v3.Chart("laravel-chart", {
    chart: "laravel",
    version: "x.y.z", // Replace "x.y.z" with the version number of the Laravel Helm chart you want to deploy
    // If the Laravel Helm chart is from a custom repository, specify `repo` and `fetchOpts`
    // repo: "https://charts.example.com/", // Replace this with your Helm chart's repository URL
    // You can provide custom values to the Helm chart using 'values'. Here's an example:
    values: {
        service: {
            type: "ClusterIP",
        },
        // Add appropriate values for Laravel deployment
    },
}, { provider: cluster.provider });

// Export the Laravel endpoint
export const laravelEndpoint = laravelHelmChart.getResourceProperty("v1/Service", "laravel-chart", "status");

// Note: Be sure to replace the chart name and url with the correct chart reference and any values
// necessary for your Laravel Helm chart. In this case, "laravel-chart" is used as a placeholder and may
// differ based on the Helm chart you are using.
```

Here's an explanation of the key components in this program:

- `eks.Cluster`: This class creates an EKS cluster by utilizing other AWS resources such as `aws.eks.Cluster` and `aws.ec2.Vpc`. Here, we initiate it with a desired Kubernetes version and other default settings.
- `kubernetes.helm.v3.Chart`: Deploy Helm charts on a Kubernetes cluster. In this example, it is used to deploy the Laravel Helm chart. You need to specify the chart name, and optionally the chart version and repository.

Make sure you check the Helm chart's documentation for Laravel for any prerequisites and configuration options you may need to define.

To apply these changes using Pulumi, you would run `pulumi up` with the Pulumi CLI. This command would create the EKS cluster and deploy the Laravel Helm chart into it. Remember to have your AWS credentials configured and also install the Pulumi CLI and the necessary Pulumi packages for this code to work.

Lastly, this program assumes you know the Helm chart's name and repository for Laravel and that you have sufficient permissions in AWS to create and manage EKS clusters. If you need specific network configuration or IAM roles and policies for your EKS cluster and nodes, you would define those in the cluster configuration as well.
