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

    TypeScript

    To deploy the jx-app-athens Helm chart on a Rancher-managed Kubernetes cluster, you will need to use Pulumi to interact with Rancher to set up the cluster, install the Helm chart, and manage the deployment process. Rancher uses Helm to manage Kubernetes applications and Pulumi offers a way to automate Helm chart deployments through code.

    Here's a step-by-step explanation of what the code does:

    1. Set Up Rancher Cluster: First, you'll need to create or have access to a Kubernetes cluster managed by Rancher. In this example, we'll assume that the cluster is already created and managed by Rancher, and your Pulumi code will deploy the jx-app-athens Helm chart to this cluster.

    2. Initialize the Rancher Provider: You will need to use the Rancher2 provider which allows Pulumi to interact with Rancher. This provider needs to be configured with the necessary credentials to authenticate with the Rancher API.

    3. Create a new Namespace: If needed, you can create a new Kubernetes namespace where your jx-app-athens application will reside. Otherwise, you can utilize an existing namespace.

    4. Deploy the Helm Chart: Utilize Pulumi's Helm Release resource to deploy the jx-app-athens Helm chart into the specified namespace within your Rancher-managed cluster.

    5. Export Outputs: At the end, you may export any necessary information such as the external IP address or hostname that could be used to access the jx-app-athens service if it's exposed externally.

    Here is a Pulumi TypeScript program that accomplishes the deployment:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Initialize the Rancher provider const rancherProvider = new rancher2.Provider("rancher", { apiUrl: "https://<RANCHER_API_URL>", // Replace with your Rancher API URL accessKey: "<ACCESS_KEY>", // Replace with your Access Key secretKey: "<SECRET_KEY>", // Replace with your Secret Key }); // Create a Kubernetes namespace for the jx-app-athens application, if required const appNamespace = new k8s.core.v1.Namespace("app-namespace", { metadata: { name: "athens-app" }, }, { provider: rancherProvider }); // Deploy the jx-app-athens Helm chart const athensChart = new k8s.helm.v3.Release("athens-chart", { chart: "jx-app-athens", version: "0.1.0", // Replace with the desired chart version repositoryOpts: { repo: "http://chartmuseum.jenkins-x.io", }, namespace: appNamespace.metadata.name, // Set custom values or configurations needed by the chart here // This example shows a sample value, replace it with actual data. values: { persistence: { enabled: true, storageClass: "rancher-nfs", size: "10Gi", }, }, }, { provider: rancherProvider, dependsOn: [appNamespace] }); // Export the application URL, using the created LoadBalancer service from the deployed Helm chart // Note: You will need to check the actual service deployed by the jx-app-athens chart. export const applicationURL = athensChart.status.apply(status => status.loadBalancer.ingress[0].hostname);

    In this code, you must replace the placeholder values in <RANCHER_API_URL>, <ACCESS_KEY>, and <SECRET_KEY> with actual values from your Rancher setup. You may also need to replace the values object within the athensChart definition with correct configurations for your jx-app-athens Helm chart.

    Keep in mind that depending on your setup, you might have to adjust the exported applicationURL to match the actual service type and name created by the Helm chart when deployed. If the service is of type NodePort instead of LoadBalancer, you would extract the URL differently.

    Additionally, remember to include your dependencies by installing Pulumi and setting up the necessary Pulumi stacks and configurations. Make sure you have the Rancher2 Pulumi provider installed and configured correctly, and authenticate with the Kubernetes cluster that Rancher manages.
