Deploy the nuxt3 helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy a Nuxt3 Helm chart on AWS EKS, you'll need to set up the following:

1. **EKS Cluster**: An Amazon Elastic Kubernetes Service (EKS) cluster is the foundation of your Kubernetes environment on AWS.
2. **Helm Chart**: Helm helps you manage Kubernetes applications - Helm Charts help you define, install, and upgrade even the most complex Kubernetes application.

Here's how you can do it:

1. **Creating an EKS cluster**: Using Pulumi, you can instantiate an EKS cluster using the `aws.eks.Cluster` resource. The EKS cluster will provide the necessary Kubernetes environment for your Nuxt3 application.

2. **Deploying Nuxt3 with Helm**: Once the EKS cluster is ready, you'll use the `kubernetes.helm.v3.Chart` resource to deploy your application from a Helm chart.

Below is a Pulumi program written in TypeScript that demonstrates these steps:

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

// Create an EKS cluster.
const cluster = new eks.Cluster("my-cluster", {});

// Export the cluster's kubeconfig.
export const kubeconfig = cluster.kubeconfig;

// Use the cluster's kubeconfig to instantiate a new Kubernetes provider.
const k8sProvider = new kubernetes.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy Nuxt3 via a Helm chart.
const nuxt3Chart = new kubernetes.helm.v3.Chart("nuxt3", {
    chart: "nuxt3",
    version: "1.0.0", // Replace with the exact version you want to deploy
    // Add the Helm repository URL that contains the Nuxt3 chart
    // You typically find this in the documentation of the Helm chart or by searching the Helm hub.
    fetchOpts: {
        repo: "https://helm-repository-where-nuxt3-chart-is-hosted.com/", // Replace this with the correct repo URL
    },
}, { provider: k8sProvider });

// Optionally, you can export the Helm release status
export const nuxt3Status = nuxt3Chart.status;
```

In the above program:

- We create an EKS cluster using the `eks.Cluster` class from the `@pulumi/eks` package. This will provision an EKS cluster with all the default settings, which should be sufficient for a basic Nuxt3 application.
- We then export the `kubeconfig` file generated by Pulumi, which will allow you to interact with your cluster via `kubectl` from your local machine.
- We define a Kubernetes provider using the created kubeconfig so that we can deploy resources into the EKS cluster.
- We deploy the Nuxt3 application using `kubernetes.helm.v3.Chart`. You need to provide the appropriate Helm chart repository URL and chart version that aligns with the Nuxt3 release you wish to deploy.

Keep in mind that in a real-world scenario, you might need to tweak the EKS cluster configuration and the Helm chart deployment settings to align with your particular requirements, such as setting node sizes, specifying different subnets, or configuring the Helm release with specific values which can be done through the `values` argument of the `Chart` resource.

Remember to install all the necessary Pulumi package dependencies in your project using npm or yarn before running the Pulumi program:

```bash
npm install @pulumi/aws @pulumi/eks @pulumi/kubernetes
```

After you run the Pulumi up command and it finishes, the Nuxt3 application should be deployed to the EKS cluster.

Please note, as this is a high-level overview, you may need to adjust parameters, resource options, or configurations to match your exact specifications and ensure all dependencies and permissions are handled correctly.
