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

    TypeScript

    To deploy the jenkins-x-platform Helm chart on an OpenShift cluster using Pulumi, you will need to use the @pulumi/kubernetes package which enables you to write Kubernetes infrastructure as code in TypeScript. This package provides the Chart resource that allows you to deploy Helm charts.

    Before you begin, you must have access to an OpenShift cluster and have the kubectl CLI configured to communicate with it. You also need Pulumi CLI installed and set up to manage resources.

    The following steps will guide you through the process of writing a program that deploys the jenkins-x-platform Helm chart to your OpenShift cluster:

    1. Set up the Pulumi project and import the necessary packages.
    2. Define the Chart resource, referencing the jenkins-x-platform Helm chart and configure it according to your needs.
    3. Execute the Pulumi program to deploy the Helm chart to your OpenShift cluster.

    Here's the program that deploys the jenkins-x-platform chart:

    import * as k8s from "@pulumi/kubernetes"; // Create a new instance of the kubernetes.helm.v3.Chart class to deploy jenkins-x-platform. // The `jenkins-x-platform` chart is fetched from its Helm repository using the appropriate repo URL. const jenkinsXChart = new k8s.helm.v3.Chart("jenkins-x", { // Specify the chart name. chart: "jenkins-x-platform", // Specify the repository where the chart is located. // Note: You might need to replace this URL with the current repository that maintains the jenkins-x-platform Helm chart. repo: "https://charts.jenkins.io", // Version can be specified if you want a specific version of the Helm chart. // version: "<chart-version>", // Namespace where you want to deploy jenkins-x. OpenShift projects are synonymous with Kubernetes namespaces. namespace: "jenkins-x", // Make sure this namespace exists in your OpenShift cluster or add { createNamespace: true } // Values allow you to customize Helm chart values. Replace the placeholder `{ ... }` with actual configuration values required for Jenkins X. values: { // Add your custom values here }, // FetchOpts can be used to configure additional settings for fetching the Helm chart. fetchOpts: { // Home could be the directory where Helm stores its cache or configuration. // home: "<path-to-helm-home>", }, }, { // Provider is set only if you want to target a specific Kubernetes provider instance, for instance, if you have // multiple configurations for different clusters. In most cases, this can be omitted, and Pulumi will use the default provider configuration. // provider: myK8sProviderInstance, }); // Pulumi stack output export const jenkinsUrl = jenkinsXChart.getResourceProperty("v1/Service", "jenkins-x", "status").apply(status => status.loadBalancer.ingress[0].hostname);

    In the example above, we used the Chart resource to deploy the jenkins-x-platform chart from its Helm repository. You will need to provide any custom values required by the chart in the values field. If you have multiple Kubernetes provider instances, you can specify a particular provider instance in the provider option.

    After saving the above code in a file named index.ts, you can deploy it to your OpenShift cluster by running the following commands in your terminal:

    pulumi up

    This command will prompt you to confirm the deployment. Once confirmed, Pulumi will proceed with the deployment of the Jenkins X Helm chart to your OpenShift cluster.

    The last line of the program uses export to provide a stack output that gives you the URL at which Jenkins X should be accessible, assuming it is exposed via a LoadBalancer service type with an external ingress hostname.

    Remember to consult the Jenkins X Helm chart documentation to understand the specifics of the necessary values and configurations needed for your context.
