1. Deploy the elasticsearch-data helm chart on Rancher


    To deploy the elasticsearch-data Helm chart on a Rancher managed Kubernetes cluster using Pulumi, you will need to perform several steps:

    1. Set up the Rancher project and credentials: Ensure that you have a Rancher-managed Kubernetes cluster set up and you have the necessary credentials to interact with it. Obtain the cluster ID and other details you might need for authentication.

    2. Install the Pulumi CLI and set up your Pulumi project: If you haven't already, you will need to install the Pulumi CLI on your machine and create a new Pulumi project. A Pulumi project is simply a directory with some files that tell Pulumi how to create and manage your cloud resources.

    3. Reference the Pulumi Rancher2 provider: To interact with Rancher resources, you will need to use the pulumi/rancher2 provider. This allows you to create resources within a Rancher-managed Kubernetes cluster.

    4. Define the Kubernetes provider for Rancher: Since Helm charts are deployed within a Kubernetes cluster, you will need to instantiate a Kubernetes provider that points to your Rancher cluster. This provider will use the credentials you set up in the first step.

    5. Deploy the Helm chart: Once you have all the necessary providers set up, you can define a helm.v3.Chart resource to deploy the elasticsearch-data Helm chart from its repository.

    Here's a TypeScript program that demonstrates these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as rancher2 from "@pulumi/rancher2"; // Initialize a Rancher2 provider instance using the cluster ID and other required credentials. // You'll need to replace the placeholders with your actual Rancher cluster information. const rancherProvider = new rancher2.Provider("rancherProvider", { // The API URL of your Rancher instance apiUrl: "https://rancher.mycompany.com/v3", // Access key for API operations accessKey: "ACCESS_KEY", // Secret key for API operations secretKey: "SECRET_KEY", // Replace with your Rancher cluster ID clusterId: "CLUSTER_ID", }); // Initialize a Kubernetes provider instance that uses the above Rancher2 provider. // This tells Pulumi to deploy resources to the Rancher-managed Kubernetes cluster. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: rancherProvider.kubeconfig.apply(JSON.stringify), }); // Deploy the elasticsearch-data Helm chart using the Helm provider. const elasticsearchDataChart = new k8s.helm.v3.Chart("elasticsearch-data", { // The repository that contains the Helm chart. repo: "elastic", // The name of the Helm chart. chart: "elasticsearch", // Override default configuration values here as needed. values: { // The actual values will depend on the specifics of the elasticsearch Helm chart // and the configuration you need. You will likely need to customize this. roles: { data: true, master: false, ingest: false, }, // Any other values to configure the chart. }, }, { provider: k8sProvider }); // Export any pertinent information, such as the Helm release status or service endpoint. export const elasticsearchDataStatus = elasticsearchDataChart.status;

    Before running the above program, make sure you replace placeholders like ACCESS_KEY, SECRET_KEY, CLUSTER_ID, and the values within the elasticsearch-data Helm chart configuration with your actual data.

    You'll execute this Pulumi program by running the following commands:

    • To preview the deployment without actually making any changes, run pulumi preview.
    • To deploy the chart to your cluster, run pulumi up.

    This program doesn't include error handling or advanced configurations, so you might need to make adjustments based on your environment and the requirements of the elasticsearch-data Helm chart. Always review the chart's documentation to ensure that your configuration values are correct.

    For more details on the Pulumi resources used in this program, refer to the Pulumi API documentation:

    Please ensure you have the necessary permissions to deploy resources on Rancher and you've initialized a Pulumi stack where this code will be deployed.
