Deploy the Nuxt3 Helm Chart on Digital Ocean Kubernetes Service

Introduction

In this solution, we will deploy a Nuxt3 application on a Digital Ocean Kubernetes Service (DOKS) cluster using Pulumi. Pulumi is an Infrastructure as Code (IaC) tool that allows you to define and manage cloud resources using familiar programming languages. We will use the Pulumi TypeScript SDK to create and configure the necessary resources, including the Kubernetes cluster and the Helm chart for Nuxt3.

Step-by-Step Explanation

Step 1: Set Up Pulumi Project

First, we will set up a new Pulumi project in TypeScript. This involves initializing the project and installing the required Pulumi packages for Digital Ocean and Kubernetes.

Step 2: Configure Digital Ocean Provider

Next, we will configure the Digital Ocean provider with the necessary authentication details. This will allow Pulumi to interact with the Digital Ocean API and create resources on our behalf.

Step 3: Create Kubernetes Cluster

We will create a new Kubernetes cluster on Digital Ocean using the Pulumi Digital Ocean SDK. This cluster will serve as the environment where we will deploy our Nuxt3 application.

Step 4: Deploy Nuxt3 Helm Chart

Finally, we will deploy the Nuxt3 Helm chart to the Kubernetes cluster using the Pulumi Kubernetes SDK. This will involve specifying the Helm chart details and any necessary configuration values.

Key Points

• Pulumi allows you to define and manage cloud resources using familiar programming languages.
• We will use the Pulumi TypeScript SDK to create and configure a Kubernetes cluster on Digital Ocean.
• The Nuxt3 application will be deployed using a Helm chart, which simplifies the deployment process.
• Pulumi provides a seamless way to manage the entire infrastructure lifecycle, from creation to updates and deletions.

Conclusion

In this solution, we demonstrated how to deploy a Nuxt3 application on a Digital Ocean Kubernetes Service (DOKS) cluster using Pulumi. By leveraging Pulumi’s TypeScript SDK and the Helm chart for Nuxt3, we were able to define and manage our cloud resources in a programmatic and efficient manner. This approach not only simplifies the deployment process but also provides greater flexibility and control over our infrastructure.

Full Code Example

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

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("my-cluster", {
    region: "nyc3",
    version: "1.21.5-do.0",
    nodePool: {
        name: "default",
        size: "s-2vcpu-4gb",
        nodeCount: 3,
    },
});

// Export the kubeconfig
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

// Create a Kubernetes provider using the kubeconfig
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploy the Nuxt3 Helm chart
const nuxt3Chart = new k8s.helm.v3.Chart("nuxt3", {
    chart: "nuxt3",
    version: "latest",
    fetchOpts: {
        repo: "https://charts.nuxtjs.org",
    },
    values: {
        replicaCount: 2,
        service: {
            type: "LoadBalancer",
        },
    },
}, { provider: k8sProvider });

// Export the resources of the Nuxt3 Helm chart
export const nuxt3ChartResources = nuxt3Chart.getResource("v1/Service", "nuxt3");
