1. Deploy the elasticsearch-sed helm chart on Rancher


    To deploy the elasticsearch-sed helm chart on Rancher using Pulumi, you'll follow these steps:

    1. Define the Rancher Cluster: You need to have a Rancher Kubernetes cluster where the helm chart will be deployed. This could be an existing cluster or one that you create using Pulumi.

    2. Install Pulumi's Rancher 2 Provider: This is required to interact with Rancher's resources. The Rancher 2 provider allows you to manage Rancher resources such as clusters, catalogs, and workloads.

    3. Define the Catalog: In Rancher, a catalog is a set of Helm chart repositories that Rancher can connect to, enabling you to deploy apps from those catalogs. If the elasticsearch-sed helm chart is in a custom catalog, you'll need to add that catalog to Rancher.

    4. Deploy the Helm Chart: Once the catalog is set up, you can deploy the helm chart to your Kubernetes cluster.

    Here's a TypeScript program demonstrating how you would set up Pulumi to deploy the elasticsearch-sed helm chart on a Rancher-managed cluster.

    This program assumes you already have a Rancher cluster set up, the elasticsearch-sed helm chart is available in a catalog connected to Rancher, and you have the necessary permissions configured. Additionally, you must have Pulumi installed with your Rancher provider configured. You will need to replace some placeholders with actual values specific to your setup.

    import * as rancher2 from "@pulumi/rancher2"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create a new Pulumi Stack const stack = new pulumi.Stack("elasticsearch-on-rancher"); // Instantiate the Rancher2 provider const rancher2Provider = new rancher2.Provider("rancher-provider", { apiUrl: "<RANCHER_API_URL>", // replace with your Rancher API URL accessKey: "<RANCHER_ACCESS_KEY>", // replace with your Rancher Access Key secretKey: "<RANCHER_SECRET_KEY>", // replace with your Rancher Secret Key }, {dependsOn: stack}); // Use Rancher2 provider to reference an existing Rancher2 cluster const cluster = new rancher2.Cluster("cluster", { // You'll need to set the actual ID of an existing Rancher Cluster here clusterId: "<RANCHER_CLUSTER_ID>", }, { provider: rancher2Provider }); // Set up the Kubernetes provider to deploy to the Rancher Cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfig, // Use the kubeconfig from the Rancher cluster }, {dependsOn: [cluster, rancher2Provider]}); // Deploy the Elasticsearch Helm chart to the Kubernetes cluster const elasticsearchChart = new k8s.helm.v3.Chart("elasticsearch-sed", { chart: "elasticsearch-sed", version: "<HELM_CHART_VERSION>", // replace with the version of the helm chart namespace: "<NAMESPACE>", // replace with the namespace if not default fetchOpts:{ repo: "<HELM_CHART_REPOSITORY_URL>", // replace with Helm chart's repository URL }, // Values from the helm chart you want to customize values: { // You would specify the chart value overrides here, for example: // replicas: 3, }, }, { provider: k8sProvider }); // Export the application URL by querying the load balancer export const applicationUrl = elasticsearchChart.getResourceProperty("v1/Service", "elasticsearch-sed", "status") .apply(status => `http://${status.loadBalancer.ingress[0].ip}`);

    In the program above:

    • We first set up a new Pulumi stack and instantiate a provider for Rancher 2, providing it with API credentials.

    • We then use the Rancher 2 provider to reference an existing Rancher cluster by its ID.

    • With the reference to the cluster, we set up a Kubernetes provider that uses the kubeconfig from the Rancher cluster, allowing us to deploy resources to it.

    • The k8s.helm.v3.Chart resource is used to deploy the elasticsearch-sed helm chart to the chosen namespace within the cluster. You would need to specify the chart version, and if you have custom configurations for your Elasticsearch helm chart, you would place them in the values of the Chart resource.

    • Last, we export the application URL obtained from the service load balancer, which would allow you to access the Elasticsearch service from a web browser.

    Replace the placeholder values with those that apply to your specific Rancher and Kubernetes environment, then run this program using the Pulumi CLI to deploy the elasticsearch-sed helm chart to your Rancher cluster.
