1. Deploy the jx-app-jenkins helm chart on Rancher


    To deploy the jx-app-jenkins Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, you will need to follow several steps:

    1. Set up a Rancher Kubernetes cluster: You first need a working Kubernetes cluster managed by Rancher. You can create a new cluster within Rancher or import an existing one.

    2. Install the Rancher2 Pulumi Provider: This provider allows you to interact with Rancher resources through Pulumi.

    3. Deploy the Helm Chart: You will use the Helm class from the kubernetes Pulumi provider to deploy the jx-app-jenkins chart.

    Here's a sample Pulumi program that illustrates these steps in TypeScript. This assumes that you have a Kubernetes cluster managed by Rancher and appropriate access rights to deploy Helm charts to it.

    First, ensure you have the necessary Pulumi packages installed:

    npm install @pulumi/pulumi npm install @pulumi/kubernetes npm install @pulumi/rancher2

    Next, you can use the following Pulumi program:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Step 1: Configure Rancher Kubernetes provider (if necessary) // In this case, it's assumed that the cluster is already provisioned, // and the kubeconfig file is properly configured to access it. // Step 2: Define a new rancher2 provider instance const rancher2Provider = new rancher2.Provider("my-rancher", { // You must already be authenticated to Rancher and have an API token apiToken: 'your-rancher-api-token', apiUrl: 'your-rancher-server-url', }); // Step 3: Deploy jx-app-jenkins helm chart on the rancher2 cluster const jenkinsHelmChart = new k8s.helm.v3.Chart("jx-app-jenkins-helm-chart", { chart: "jenkins", version: "YOUR_DESIRED_CHART_VERSION", // specify the version you want to deploy fetchOpts: { repo: "https://charts.jenkins.io", // the repository where the chart is located }, // Define namespace, values and other chart parameters under the 'values' // key or by passing the --values flag in CLI-based installations. values: { /* provide customized values.yaml content here, check https://github.com/jenkinsci/helm-charts for chart values */ }, }, { provider: rancher2Provider }); // Optionally, export the endpoint to access Jenkins dashboard (usually a LoadBalancer IP or DNS) export const jenkinsEndpoint = jenkinsHelmChart.getResourceProperty( "v1/Service", "jx-app-jenkins-helm-chart-jenkins", // assuming this will the service name "status" ).apply(status => status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname);

    This Pulumi program performs three main tasks:

    • Setting up the Rancher2 provider: To interact with Rancher using Pulumi, you should have a rancher2.Provider instance. The apiToken and apiUrl refer to the API token to authenticate with your Rancher server and the URL of your Rancher server, respectively.

    • Deploys the Helm chart: The k8s.helm.v3.Chart class is used to deploy the jx-app-jenkins chart. You will need to provide specific values such as the version and repository of the chart, as well as any custom values you want to provide to the chart.

    • Exporting the Jenkins endpoint: After the chart is deployed, you may want to access the Jenkins dashboard. The service endpoint can usually be obtained from the status.loadBalancer.ingress field of your Jenkins service. The jenkinsEndpoint will export this value so you can easily access Jenkins once it's up.

    Note that you will need to replace 'your-rancher-api-token', 'your-rancher-server-url', and any other placeholder content with actual data from your setup. Please ensure you have the necessary permissions and the kubeconfig for the relevant Kubernetes cluster is correctly set up to work with Pulumi.

    Remember that Pulumi scripts are executed using the Pulumi CLI. Once you have the script, navigate to the directory containing the script in your terminal, and then run pulumi up to deploy the changes described by the script to your cloud provider.
