1. Deploy the vps helm chart on Kubernetes


    To deploy a Helm chart on Kubernetes using Pulumi, you will need to use the Chart resource from the @pulumi/kubernetes package. This resource allows you to deploy applications packaged as Helm charts onto a Kubernetes cluster. Helm is a package manager for Kubernetes that packages multiple Kubernetes resources into a single logical deployment unit called a chart.

    Here's how you might deploy a hypothetical Helm chart named vps in TypeScript using Pulumi:

    1. First, ensure that you have both Pulumi and Helm installed on your system.
    2. Next, you will set up Pulumi to connect to your Kubernetes cluster. Make sure your kubeconfig is correctly set up to interact with your cluster.
    3. You will then write a Pulumi program that defines a kubernetes.helm.sh/v3.Chart resource, which represents the vps chart you wish to deploy.

    Below is a Pulumi program that achieves the deployment:

    import * as kubernetes from "@pulumi/kubernetes"; // Create an instance of the Helm Chart const vpsChart = new kubernetes.helm.v3.Chart("vps-helm-chart", { chart: "vps", version: "1.2.3", // replace with a specific chart version; omit if you want to pull the latest // Set the namespace where the Helm chart will be installed namespace: "default", // You can add custom values which will overwrite the defaults of the Helm chart values: { // Provide configuration values here, like // serviceType: "LoadBalancer", }, // In case you have your Helm chart in a custom repository, you need to add `repo` attribute here // repo: "http://myhelmrepo.com/charts", }); // Export any pertinent resources; for example, the public URL if there's an associated LoadBalancer service export const vpsChartPublicUrl = vpsChart.getResourceProperty("v1/Service", "my-service", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    This program does the following:

    • It imports the @pulumi/kubernetes module, which contains the necessary classes for working with Kubernetes resources in Pulumi.
    • It creates a new Helm chart instance by calling new kubernetes.helm.v3.Chart(). You pass a name for this instance ("vps-helm-chart") as the first argument.
    • The chart name ("vps") is passed in the chart key inside the second argument's options object. This should be the name of the Helm chart you wish to deploy.
    • Optionally, the version key specifies the version of the Helm chart you want to deploy. If you want to always deploy the latest version, you can omit this option.
    • The namespace key is used to specify which namespace in the Kubernetes cluster you want to deploy the chart to. This example uses the default namespace.
    • The values key allows you to customize the Helm chart by overriding its default values. Replace the placeholder with actual configuration keys and values that are appropriate for the vps chart.
    • If your Helm chart is located in a custom repository, you would uncomment the repo key and set its value to your repository's URL.
    • At the end of the Pulumi program, there's an example of how to export a resource property, such as a Service's public URL, after it's been created by the Helm chart. Adjust the getResourceProperty call to reference any specific resources and properties you wish to export.

    To run this Pulumi program, you would execute it within a Pulumi project. If you have not set up one, you can create a new project by running pulumi new in the terminal and selecting a template that matches your use case. Once the project is set up, save this code in the index.ts file, and run pulumi up to execute the program and deploy the chart to your Kubernetes cluster.

    Remember to replace the placeholders and parameters such as chart, version, values, and repo with the actual values for the vps chart you are deploying.
