1. Deploy the jenkins-x-platform helm chart on Kubernetes

    TypeScript

    To deploy the Jenkins X platform using a Helm chart on a Kubernetes cluster, you will utilize the Chart resource from the Pulumi Kubernetes provider. Jenkins X is a powerful CI/CD system designed for Kubernetes. It can be installed via Helm, which is a package manager for Kubernetes that allows easy installation and management of applications.

    To use the Chart resource, you need to provide values for:

    • the name of the Helm chart (jenkins-x-platform in this case),
    • the repository where the Helm chart is located,
    • any custom values you wish to configure,

    A Pulumi program to deploy jenkins-x-platform on Kubernetes might look like this:

    import * as k8s from "@pulumi/kubernetes"; // Create a Kubernetes namespace for Jenkins X. const jxNamespace = new k8s.core.v1.Namespace("jx", { metadata: { name: "jx" // The namespace where Jenkins X will be installed }, }); // Deploy Jenkins X using the Helm Chart. // You must have Helm and its server-side component, Tiller, set up in your cluster. const jenkinsXChart = new k8s.helm.v3.Chart("jenkins-x", { chart: "jenkins-x-platform", // The name of the chart version: "2.0.1369", // Specify the version of the Helm Chart to use namespace: jxNamespace.metadata.name, // Deploy within the created namespace fetchOpts: { // Specify the repository containing the jenkins-x-platform chart repo: "https://jenkins-x-charts.github.io/v3-dev/" }, // Provide any custom values you want to pass to the Helm chart values: { // For example, if you want to set a custom domain // domain: "example.com", // and any other configuration values that jenkins-x-platform chart supports. }, }, { provider: /* a kubernetes provider if not using the default one */ }); // Export the generated YAML manifest of Helm chart resources. export const jenkinsManifest = jenkinsXChart.resources;

    Here's a breakdown of what we're doing in this Pulumi program:

    • We import the @pulumi/kubernetes package which allows us to work with Kubernetes resources in Pulumi.

    • We create a Kubernetes namespace called jx where all the resources related to Jenkins X will be created.

    • We instantiate a Chart object, jenkinsXChart, which represents the jenkins-x-platform Helm chart. The Chart is given several fields:

      • chart: Specifies the name of the chart to install; in our case, "jenkins-x-platform".
      • version: Specifies the version of the Helm chart to use; it should be set to a specific version to ensure idempotent deployments.
      • namespace: Indicates the namespace where the chart should be deployed. We deploy it to the namespace we created earlier.
      • fetchOpts.repo: Specifies the repository where the Helm chart is located. Make sure to use the correct repository URL for the Jenkins X Helm chart.
      • values: This field would contain customization for the Helm chart. In this example, it's a placeholder for you to fill in your configuration parameters based on the Jenkins X chart’s values.yaml file.

      To apply this Pulumi program, save it to a index.ts file, set up the Kubernetes context for your Pulumi program to access your cluster, and then run pulumi up. This will start the deployment of Jenkins X into your Kubernetes cluster.

    Please ensure that you have Helm and Tiller properly installed and configured in your cluster, as it's a prerequisite for deploying charts with Pulumi. Additionally, make sure you have a Kubernetes cluster running and kubectl configured to connect to it. The Pulumi Kubernetes provider uses kubectl to interact with the cluster.
