1. Deploy the openshift-jenkins helm chart on Kubernetes


    To deploy the openshift-jenkins Helm chart on a Kubernetes cluster using Pulumi, you'll first need to ensure you have a Kubernetes cluster up and running. Pulumi will communicate with this cluster using the current context in your local .kubeconfig file or using cluster configuration passed programmatically.

    Below is the Pulumi program written in TypeScript to deploy the openshift-jenkins Helm chart onto an existing Kubernetes cluster. The program uses the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider which represents a Helm chart in a Pulumi program.

    The Helm chart resource accepts various configuration parameters such as the chart name, values to customize the deployment, the namespace to deploy into, and other chart-specific options.

    Here's the detailed Pulumi program:

    import * as k8s from "@pulumi/kubernetes"; // Name of the Helm chart to be deployed. const chartName = "openshift-jenkins"; // The repository where the Helm chart is located. // Make sure to use the correct repository that contains the openshift-jenkins chart. const chartRepo = "https://example.com/helm-charts"; // Replace with actual Helm repo URL // The version of the Openshift-Jenkins Helm chart you wish to deploy. const chartVersion = "X.Y.Z"; // Replace with a specific chart version // Initialization of the Helm chart. const openshiftJenkinsChart = new k8s.helm.v3.Chart(chartName, { repo: chartRepo, chart: chartName, version: chartVersion, // Values for the chart can be provided in the 'values' parameter. // These will override the default values in the chart's `values.yaml`. // For example, you could provide the admin password, persistence options, or any other custom configuration. values: { // Add any values here to customize your Openshift Jenkins deployment. // Example: // AdminPassword: "yourStrongPassword" }, // The namespace to deploy the chart into. If not specified, it will be installed in the default namespace. // Make sure to create the namespace if it does not exist or if you're not using the default. namespace: "jenkins-namespace", // Replace with the namespace where you want to deploy the chart. }); // Exports to access the deployed helm chart easily outside of Pulumi. // For examples: exporting the URL to access the Jenkins instance if it's exposed. export const jenkinsUrl = openshiftJenkinsChart.getResourceProperty( "v1/Service", `${chartName}-openshift-jenkins`, "status").apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

    Before deployment, you should have the following prerequisites:

    • A Kubernetes cluster where you can deploy the chart.
    • Pulumi CLI installed and configured to connect to your Kubernetes cluster.
    • Access to the Helm chart repository containing the openshift-jenkins Helm chart.
    • Decide if custom values should override the defaults in values.yaml for the Helm chart, and if so, update the values object in the code accordingly.
    • Replace chartRepo and chartVersion with actual values specific to the openshift-jenkins Helm chart you want to deploy.

    By running this Pulumi program, you will deploy the openshift-jenkins Helm chart to your Kubernetes cluster. Note that you will need network access to the specified chartRepo from wherever you're running Pulumi, which could be your local machine or a CI/CD pipeline.

    Please double-check the configuration, especially the chart version and repository URL, before running the program. If the openshift-jenkins Helm chart exposes any services, e.g., a web UI, the jenkinsUrl export will provide you with the address to access the service once it's available. If the service requires internal cluster access instead of being available publicly, you will need a different method to access the service, such as using port-forwarding or a VPN to the Kubernetes cluster network.
