1. Deploy the woonley helm chart on Kubernetes

    TypeScript

    To deploy a Helm chart on Kubernetes using Pulumi, we'll utilize the Chart resource from the @pulumi/kubernetes package, which represents a chart from Helm, a package manager for Kubernetes that packages multiple Kubernetes resources into a single logical deployment unit called a "chart."

    In this program, we will perform the following steps:

    1. Import the necessary Pulumi and Kubernetes libraries.
    2. Create a Kubernetes provider to interact with your target Kubernetes cluster.
    3. Define a new Helm chart resource with the details of the woonley chart.
    4. (Optional) Export any outputs that you might find useful, such as the deployed service endpoint.

    First, make sure you have Pulumi installed and set up with the appropriate Kubernetes cluster credentials. Furthermore, you need to have Helm installed in your system, as @pulumi/kubernetes will use Helm's client-side capabilities.

    Below is the Pulumi program in TypeScript that demonstrates how to deploy a Helm chart named woonley. Please note that woonley is a placeholder name; you would need to replace it with the actual chart name and provide the correct repository URL that hosts your Helm chart.

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Step 2: Configure Kubernetes provider. // Note: Assumes you have configured your Kubernetes cluster credentials via `kubectl` or `kubeconfig` file. const provider = new k8s.Provider('k8s-provider', { // If you need to specify a specific kubeconfig, uncomment and update the line below. // kubeconfig: '<your-kubeconfig-content-here>', }); // Step 3: Define a new Helm chart resource for the 'woonley' chart. // Replace `<your-chart-repository>` with the actual URL to the repository where the woonley chart is located. const woonleyChart = new k8s.helm.v3.Chart('woonley-chart', { chart: 'woonley', // You can specify the version of the chart if needed. // version: '1.2.3', // If the chart requires custom values, provide them as an object. // values: { key1: 'value1', key2: 'value2' }, // Specify the repository options where your chart is hosted. fetchOpts: { repo: '<your-chart-repository>', }, }, { provider: provider }); // Step 4: (Optional) Export the endpoint of the deployed chart, if applicable. // For example, if the chart creates a service of type LoadBalancer or NodePort, you can obtain its URL. export const appEndpoint = woonleyChart.getResourceProperty( 'v1/Service', 'woonley-service', 'status' ).apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

    In the snippet above:

    • We create a Kubernetes Provider that will interact with our Kubernetes cluster.
    • We declare a Chart resource, specifying the name woonley-chart, and indicate the Helm chart name (woonley). We also specify that it should use Helm version 3, which is represented by k8s.helm.v3.
    • The fetchOpts property contains the repository (repo) from which to fetch the chart. You'll need to replace <your-chart-repository> with the URL of your Helm chart's repository.
    • Optionally, if your Helm chart exposes any services, such as a LoadBalancer or NodePort, you can export these details as stack outputs using export const. The actual resource properties might vary depending on the Helm chart used.

    Remember to replace the placeholder values with the actual values that pertain to your Helm chart and Kubernetes environment.
