1. Deploy the jambonz helm chart on Kubernetes

    TypeScript

    To deploy the Jambonz Helm chart on a Kubernetes cluster using Pulumi, you will need to write a Pulumi program that utilizes the Helm Chart resource from the Kubernetes provider. Here's what you'll do:

    1. Import the necessary Pulumi and Kubernetes packages.
    2. Create a Helm Chart resource, specifying the chart name, version, and any values that are necessary for customization.
    3. Export any resultant values, such as the deployed services' endpoints.

    Below is a detailed breakdown of how to accomplish each step using TypeScript.

    Initialization

    Firstly, you need to import the @pulumi/kubernetes package to gain access to Kubernetes resources within your Pulumi program.

    Creating a Helm Chart Resource

    To create a Helm chart resource, you utilize the kubernetes.helm.v3.Chart class that Pulumi offers. This class allows you to deploy Helm charts into your Kubernetes clusters. When you instantiate this class, you can specify the chart name, repository, version, and any custom values you wish to configure for your chart.

    Here's the TypeScript Pulumi program that deploys the Jambonz Helm chart to an existing Kubernetes cluster:

    import * as k8s from '@pulumi/kubernetes'; // Name of the chart const chartName = "jambonz"; // The repository where the Helm chart is located const chartRepo = "https://helm-repository-of-jambonz/"; // Version of the chart to be deployed const chartVersion = "x.y.z"; // Replace x.y.z with the actual chart version you wish to deploy // Create a Helm Chart resource using the `jambonz` chart from the specified repository const jambonzChart = new k8s.helm.v3.Chart(chartName, { repo: chartRepo, chart: chartName, version: chartVersion, // Define any custom values for the Helm chart as needed. // This is an example structure assuming the Helm chart requires these values. // You'll need to replace these with the actual values based on the jambonz chart's requirements. values: { // For example, if jambonz chart expects a value named `serviceType` // serviceType: "ClusterIP" }, }); // Export the endpoint of the Jambonz application // The actual output will depend on the resources defined by the Helm chart // For example, if a Service was created with type LoadBalancer, you can export its endpoint export const jambonzEndpoint = jambonzChart.getResourceProperty('v1/Service', 'jambonz-service', 'status').loadBalancer.ingress[0].ip;

    Explanation

    In the program:

    • We import the @pulumi/kubernetes package to interact with Kubernetes resources.
    • We define variables for the chart name, repository URL, and chart version. Please replace the placeholder values with actual information that pertains to the Jambonz Helm chart.
    • The kubernetes.helm.v3.Chart resource is instantiated to deploy the Jambonz Helm chart. You need to replace the values content with the actual custom values your chart requires.
    • We then export the endpoint of the deployed service, so you can interact with your Jambonz application. Note that the exact fields to access the IP address may vary based on the Service definition in your Helm chart. For a LoadBalancer type service, this would typically be under the status.loadBalancer.ingress field.

    To run this Pulumi program, save it in a index.ts file, run pulumi up and Pulumi will provision the resources on your behalf, applying the specified Helm chart to your Kubernetes cluster.

    Important: This example assumes that you have already configured Pulumi with the necessary provider and have a working Kubernetes cluster to deploy resources onto. If you need assistance setting up the Pulumi Kubernetes provider or configuring it to communicate with your cluster, please refer to the Pulumi documentation on Kubernetes.
