Deploy the nuxt3 helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy a Helm chart to Kubernetes using Pulumi, you'll need to use the Chart resource from the @pulumi/kubernetes package. This resource allows you to deploy a Helm chart from a repository or a local path. For your use case, we will assume there's an existing Helm chart for Nuxt.js 3 available in a public or private Helm chart repository.

Here's a step-by-step guide, including a TypeScript program, to do this:

Set up your project: Make sure that you have Pulumi installed and configured to use with your Kubernetes cluster. You should also have kubectl configured to communicate with your cluster.
Install Pulumi Kubernetes Provider: You will need the @pulumi/kubernetes package to interact with Kubernetes through Pulumi.
Create a new Pulumi stack or use an existing one: This is a logical grouping of resources that Pulumi will manage together.
Write the TypeScript program: Use Pulumi's Chart resource to deploy the Nuxt.js 3 Helm chart to your Kubernetes cluster.
Deploy the program: Run pulumi up to execute your program and deploy the Helm chart.

Below is the TypeScript program that performs these steps:

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

// Create a Kubernetes Namespace
const namespace = new k8s.core.v1.Namespace("nuxtjs-namespace", {
    metadata: {
        name: "nuxtjs",
    },
});

// Deploy Nuxt.js 3 using a Helm Chart
const nuxtChart = new k8s.helm.v3.Chart("nuxtjs-chart", {
    chart: "nuxt3", // The name of the chart. Replace with the correct chart name if different.
    version: "1.0.0", // Specify the chart version you wish to deploy; this may vary.
    namespace: namespace.metadata.name, // Use the created namespace's name.
    // Define values that you would normally pass to 'helm install' or 'helm upgrade'
    values: {
        // Customize the values here according to the Nuxt.js chart's documentation.
        // For example:
        // service: {
        //   type: "ClusterIP",
        // },
        // image: {
        //   repository: "<your-image>",
        //   tag: "<version>",
        // },
    },
    // If the chart is stored in a private repository, you can specify additional options:
    // repo: "<your-private-repo>",
    // fetchOpts: {
    //   username: "<your-username>",
    //   password: "<your-password>",
    // },
}, { provider: k8sProvider }); // If you have multiple configurations, specify the appropriate K8s provider

// Export the resulting base URL for the deployed application
export const baseUrl = nuxtChart.getResourceProperty("v1/Service", "nuxtjs-chart", "status").apply(status => `http://${status.loadBalancer.ingress[0].ip}`);

Before running pulumi up, make sure that you have your Kubernetes cluster context set to the correct cluster where you want to deploy the Nuxt.js 3 application.

This program will create a Kubernetes namespace, then deploy the Nuxt.js 3 application into that namespace using its Helm chart. You may need to specify additional Helm values based on the requirements of your application and the configuration options the Helm chart provides.

After running pulumi up, Pulumi will output the base URL to access your Nuxt.js 3 application, assuming that the service exposes an external endpoint. If the helm chart does not create a service with an external IP, or you're deploying into an environment like Minikube, the retrieved URL may not be externally accessible; you'll need to adjust the exported value or use port forwarding to access your application.
