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

    TypeScript

    To deploy the Jenkins X platform Helm chart on a Rancher managed Kubernetes cluster using Pulumi, you'll first need to set up a Kubernetes cluster in Rancher and configure access to it. Once the cluster is ready, we can proceed to install Helm and deploy the Jenkins X platform chart.

    Prerequisites

    • You need a running Kubernetes cluster managed by Rancher.
    • You must have kubectl configured to access your Kubernetes cluster.
    • Helm must be installed and configured to use with your Kubernetes cluster.
    • Pulumi CLI must be installed on your machine.
    • Node.js and npm must be installed to run the Pulumi program in TypeScript.

    Here's a step-by-step guide on how to deploy the Jenkins X platform using Pulumi:

    1. Setting up Pulumi: If you haven’t already done so, you'll need to install Pulumi. You'll also need to set up your Pulumi account and configure the Pulumi CLI with access to your cloud provider.

    2. Configure Access to Rancher: You'll need to configure Pulumi to access the Rancher environment where your Kubernetes cluster is running. Rancher typically provides a kubeconfig file that you can use with kubectl to interact with your Kubernetes cluster.

    3. Install Helm on Your Cluster: Before you can deploy Jenkins X with Helm, you must have Helm installed on your cluster. Follow the official Helm installation guide here.

    4. Pulumi Stack Initialization: Initialize a new Pulumi stack, which is an isolated environment for your project:

      pulumi stack init jenkins-x-deployment

    5. Write the Pulumi Program: Write a TypeScript program that uses Pulumi's Kubernetes provider to deploy Jenkins X.

    Below is the TypeScript program that uses the Pulumi Kubernetes provider:

    import * as k8s from '@pulumi/kubernetes'; // Load the kubeconfig for the Kubernetes cluster managed by Rancher. // Ensure the `kubeconfig` file is present on the local filesystem. const kubeconfig = 'path-to-your-kubeconfig-file'; // Initialize a Kubernetes provider instance using the kubeconfig const provider = new k8s.Provider('k8s-provider', { kubeconfig: kubeconfig, }); // Deploy the jenkins-x-platform Helm chart. const jenkinsXChart = new k8s.helm.v3.Chart('jenkins-x', { chart: 'jenkins-x-platform', fetchOpts:{ repo: 'https://charts.jenkins.io' } }, { provider: provider }); // Export any of the necessary resources export const jenkinsHostname = jenkinsXChart.getResourceProperty('v1/Service', 'jenkins', 'status');

    Make sure to replace 'path-to-your-kubeconfig-file' with the actual path to your kubeconfig file that Rancher provides.

    This program initializes a Pulumi kubeconfig provider with the kubeconfig details for your Rancher Kubernetes cluster. Then it declares a new Helm chart resource for the Jenkins X platform, providing the chart name and repository URL. The { provider: provider } at the end tells Pulumi to deploy this chart on the Kubernetes cluster associated with our kubeconfig file.

    1. Deploy the Stack: Run the following command to start the deployment:

      pulumi up

    This command will show you a preview of the resources that Pulumi will deploy or update. Confirm the changes to start the actual deployment process.

    1. Access Jenkins X: Once the deployment is successful, you can use kubectl or the Rancher UI to retrieve the external IP or DNS name to access the Jenkins X dashboard.

    Please replace all placeholder values with your actual data and save any sensitive information, like kubeconfig, securely. Also, ensure that the version of Jenkins X's Helm chart you are deploying is compatible with your Kubernetes cluster version.

    Remember that this is just a basic guide to getting started with deploying the Jenkins X platform on Rancher with Pulumi. Depending on your Rancher and Kubernetes setup, additional steps or configuration options might be needed.
