1. Deploy the taken-component helm chart on Kubernetes


    To deploy a Helm chart on Kubernetes using Pulumi, we will use the kubernetes.helm.v3.Chart resource. This resource allows you to deploy a Helm chart from various sources, including a repository or a local path.

    Here's what the process will generally look like:

    1. We start by importing the required Pulumi and Kubernetes packages.
    2. We then specify the Helm chart we wish to deploy using the Chart resource. For this chart, we need to provide details such as the chart name, the repository where the chart is hosted (if applicable), and any configuration values we wish to override.
    3. Optionally, we can specify a namespace for our deployment. If no namespace is specified, the Helm chart will be installed in the default namespace.
    4. Lastly, we may want to export any relevant information about the deployment, such as service endpoints or other resources that the Helm chart creates.

    Below is a TypeScript program that demonstrates how to deploy a Helm chart named taken-component using Pulumi:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes Namespace const ns = new k8s.core.v1.Namespace("taken-component-ns", { metadata: { name: "taken-component" } }); // Deploy 'taken-component' Helm Chart into the Kubernetes cluster const takenComponentChart = new k8s.helm.v3.Chart("taken-component", { namespace: ns.metadata.name, // Deploy in the created namespace chart: "taken-component", // Name of the Helm chart version: "1.2.3", // Version of the Helm chart // Assumes there's a Helm repository that hosts this chart // You would replace this URL with the actual repository containing your chart fetchOpts: { repo: "http://charts.example.com/" }, values: { // Specify any values needed to override the chart's default configuration // For example, if the chart has a setting for 'replicaCount', it could be set as follows: // replicaCount: 2 } }); // Export the namespace name export const namespaceName = ns.metadata.name; // Optionally, if the chart includes a Kubernetes service of type LoadBalancer, export the service's external IP // For example: // export const serviceIP = takenComponentChart.getResourceProperty("v1/Service", "taken-component-service", "status").apply(status => status.loadBalancer.ingress[0].ip);

    In the above program:

    • We've created a namespace for the Helm chart deployment.
    • We've declared a Chart resource and provided it with the necessary configuration details, including where to fetch the chart from and what version to use.
    • We specified some placeholder values which is where you would add any Helm values to configure your chart. These values override the defaults specified by the Helm chart.
    • We added an example for how to export an attribute (like a LoadBalancer IP) of one of the resources created by the Helm chart. This export will be helpful if you want to access services deployed by the Helm chart from outside the Kubernetes cluster.

    Remember to replace the repo URL, chart name, version, and any necessary values with the actual details of the Helm chart you want to deploy. Also, adjust the getResourceProperty parameters to match the actual resources and property you need from the Helm chart.
