1. Deploy the infinispan helm chart on Rancher

    TypeScript

    To deploy an Infinispan Helm chart on Rancher using Pulumi, you need to follow these steps:

    1. Create a Kubernetes cluster in Rancher or use an existing one.
    2. Install the Helm chart for Infinispan into the Rancher Kubernetes cluster.

    For demonstration purposes, I’ll assume you already have a Kubernetes cluster managed by Rancher, and we will focus on deploying the Helm chart for Infinispan.

    The key Pulumi resource for installing a Helm chart is helm.v3.Chart, which is part of the @pulumi/kubernetes package. You will need to set up the appropriate configuration for the Helm chart using Pulumi's programming model.

    Here's a Pulumi TypeScript program that installs an Infinispan Helm chart into your Rancher-managed Kubernetes cluster:

    import * as k8s from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Reference to your existing Rancher Kubernetes cluster // Replace `<K8sCluster>` with your cluster reference identifier const cluster = new k8s.Cluster("<K8sCluster>", {/* ... */}); // The provider that points to your Rancher Kubernetes cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy Infinispan Helm chart const infinispanChart = new k8s.helm.v3.Chart("infinispan", { repo: "infinispan", chart: "infinispan", // Make sure this matches the chart name in the Helm repository version: "2.1.5", // Specify the version of the chart you want to deploy // Values to provide to the helm chart; adjust these as necessary for your Infinispan deployment values: { // Example Infinispan Helm values. Provide the specific configurations to match your requirements. // For all available options, refer to the Infinispan Helm chart documentation. clusterName: "infinispan-cluster", replicas: 3, // Other Infinispan Helm chart values... }, }, { provider: k8sProvider }); // Export the public endpoint to access Infinispan export const infinispanEndpoint = pulumi.interpolate`http://${infinispanChart.getResourceProperty("v1/Service", "infinispan", "status").apply(status => status.loadBalancer.ingress[0].hostname)}`;

    Before you run this code, you will need to replace <K8sCluster> with the identifier of your actual Kubernetes cluster managed by Rancher. You also need to make sure you're providing the correct values for the Infinispan Helm chart based on your requirements and the correct version of the Helm chart.

    The k8s.helm.v3.Chart resource is responsible for fetching the Infinispan Helm chart from the specified repository and installing it on the Kubernetes cluster configured via the k8s.Provider. The provider refers to your Rancher-managed Kubernetes cluster, and it requires a kubeconfig to interact with it, which you obtain from the cluster resource.

    At the end of the program, we export the Infinispan service endpoint, assuming it is load-balancer based. You might need to adjust that based on the actual type of service defined in the Helm chart (ClusterIP, NodePort, LoadBalancer, etc.).

    To run this program:

    1. Save the code to a file named index.ts.
    2. Run pulumi up to execute the code using Pulumi CLI.

    The pulumi up command will prompt you to confirm that you want to deploy the specified resources. Upon confirmation, Pulumi will begin the deployment process and provide you with detailed output about the state of resources.

    Remember that the provided code assumes some knowledge of your cluster's configuration, specifically the Kubernetes cluster managed by Rancher. You'll need to provide the necessary details that fit your setup.
