Deploy the nuxt3 helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

Deploying a Nuxt 3 application using a Helm chart on the Linode Kubernetes Engine can be done by utilizing Pulumi's Kubernetes provider and Helm release support. The following program takes you through this process.

To deploy a Nuxt 3 Helm chart, you'll need a Kubernetes cluster already set up in Linode. With Pulumi, you'll use the `kubernetes.helm.v3.Chart` resource type to deploy the chart to your cluster. The `Chart` resource allows you to install, update, and manage Helm charts within your Kubernetes cluster.

Here is a TypeScript program that describes how to use Pulumi to deploy a Nuxt 3 application using Helm:

```typescript
import * as kubernetes from '@pulumi/kubernetes';

// Configuration for the deployment:
const nuxt3Chart = {
    // The URL of the repository where the Nuxt 3 Helm chart is located.
    // Update this URL to point to the Helm chart repository you're using.
    repo: 'https://helm-repo-url', // Placeholder: Ensure you replace this with the actual repository URL

// The name of the Helm chart for deploying Nuxt 3.
    // Update this with the actual chart name, if different.
    chart: 'nuxt3',

// The version of the Helm chart you wish to deploy.
    version: '1.0.0', // Placeholder: Adjust the version number as needed

// Values allow you to provide configuration for the Helm chart.
    values: {
        // Specific Helm chart values for your Nuxt 3 deployment go here.
        // These may depend on the chart you are using and the configuration
        // required for your specific application.
        // Example:
        // image: {
        //     repository: 'my-repository/nuxt3-app',
        //     tag: 'latest'
        // },
        // service: {
        //     type: 'LoadBalancer' // if you want to expose your app on an external IP
        // }
    },

// The namespace where the Helm chart should be deployed.
    // Set this to an existing namespace or one you wish to create for your application.
    namespace: 'nuxt-namespace',
};

// Assuming we already have access to our Linode Kubernetes Engine Cluster via kubeconfig,
// we can deploy Nuxt 3 using a Helm chart.
const nuxt3HelmChart = new kubernetes.helm.v3.Chart('nuxt3-helm-chart', {
    path: nuxt3Chart.repo,
    chart: nuxt3Chart.chart,
    version: nuxt3Chart.version,
    values: nuxt3Chart.values,
    namespace: nuxt3Chart.namespace,
});

// Exporting the service endpoint:
export const endpoint = nuxt3HelmChart.getResource('v1/Service', 'nuxt-service')
    .status.apply(status => status.loadBalancer.ingress[0].ip);
```

To use this program:

1. Replace `https://helm-repo-url` with the URL of the repository containing the Nuxt 3 Helm chart.
2. Update `nuxt3` with the name of the Helm chart if it is different.
3. Adjust the `version` property to match the version number of the chart you want to use.
4. Replace the `values` object with the configuration values suited for your Nuxt application based on the Helm chart's requirements.
5. Change the `namespace` to an existing Kubernetes namespace or a new one you would like to create for this application.
6. Replace `'nuxt-service'` with the actual name of the service that gets created by the Helm chart if it differs.

Make sure that you have your Kubernetes configuration set correctly, so Pulumi can communicate with your Linode Kubernetes cluster. The export statement at the end will provide the endpoint IP address once your service is up and running.

Remember, before running the Pulumi program, ensure:

- You have Pulumi installed and set up.
- You have Helm CLI installed if the Helm chart you are deploying requires it.
- Your `kubeconfig` file is configured to point to your Linode Kubernetes cluster.

This program will create a Helm release in the specified namespace and deploy your Nuxt 3 application using the settings defined in the `values` object. After deployment, the program will output the IP address or DNS name that can be used to access the Nuxt 3 application, assuming that the service is exposed externally and a load balancer service type is configured.
