1. Deploy the elasticsearch-exporter helm chart on Linode Kubernetes Engine


    To deploy the Elasticsearch Exporter Helm chart on Linode Kubernetes Engine using Pulumi, you'll need to work with the following Pulumi resources:

    1. Linode Kubernetes Engine (LKE) Cluster: Before you can deploy any workloads, you first need a Kubernetes cluster. Pulumi's Linode provider does not currently exist in the Registry Results provided, but typically, the usage would involve creating an LKE cluster resource.

    2. Helm Chart: Once you have a Kubernetes cluster, you can deploy the Elasticsearch Exporter using a Helm chart. Helm is a package manager for Kubernetes, and it simplifies the deployment and management of applications on Kubernetes.

    Let's walk through the steps:

    Step 1: Initialize a New Pulumi Project

    To get started, initialize a new TypeScript Pulumi project if you haven't already done so:

    pulumi new typescript

    This command creates a new Pulumi project directory with the necessary boilerplate files, including a Pulumi.yaml file for project metadata and an index.ts file for writing your code.

    Step 2: Install Pulumi Kubernetes Package

    You'll need to install the Pulumi Kubernetes package to interact with Kubernetes resources. Run the following command:

    npm install @pulumi/kubernetes

    Step 3: Create the Kubernetes Cluster

    Although I can't provide exact code for Linode as it's not in the provided Registry Results, typically you'd use the cloud provider's Pulumi package to create a Kubernetes cluster. For Linode, you would use the @pulumi/linode package. Please check Linode's official documentation or Pulumi's documentation for the latest instructions.

    Step 4: Deploy Helm Chart

    Here's how you'd use Pulumi to deploy the Elasticsearch Exporter Helm chart to an existing Kubernetes cluster:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Provider referencing the Linode Kubernetes Engine cluster. // Replace the kubeconfig parameter with the appropriate data to connect to your LKE cluster. const provider = new k8s.Provider("lke-provider", { kubeconfig: "your-kubeconfig-data-here", }); // Deploy the Elasticsearch Exporter Helm chart using the Helm Chart resource. const elasticsearchExporter = new k8s.helm.v3.Chart("elasticsearch-exporter", { chart: "elasticsearch-exporter", version: "4.0.2", // Use the version of the chart you want to deploy namespace: "default", // Specify the namespace if not default fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts", }, }, { provider }); // Apply the Linode Kubernetes provider. // Export the name of the chart deployment export const chartName = elasticsearchExporter.metadata.apply(metadata => metadata.name);

    Make sure to replace "your-kubeconfig-data-here" with your actual kubeconfig data for connecting to your LKE cluster. You can obtain this data from the Linode Cloud Manager after you've created your Kubernetes cluster.

    This Pulumi program performs the following:

    • It initializes a new instance of the Kubernetes provider pointing to your LKE cluster.
    • It deploys the Elasticsearch Exporter Helm chart using the Chart resource from @pulumi/kubernetes.
    • It specifies the chart name, version, and the Helm repository where the chart is located.
    • The namespace argument specifies which Kubernetes namespace to deploy the chart in.
    • Finally, the program exports the name of the Helm chart deployment for your reference.

    To Run the Pulumi Program

    To apply this Pulumi program and perform the actual deployment, you'll run:

    pulumi up

    This command starts the deployment process. Pulumi will show you the execution plan and prompt for confirmation before making any changes to your cloud resources. Once you approve, Pulumi will deploy the Elasticsearch Exporter to your LKE cluster.

    Note: The above demonstration assumes you have a running LKE cluster and available kubeconfig to access it. Please ensure you meet these requirements before running the Pulumi program. For setting up the LKE cluster using Pulumi, you'll need to check Pulumi's docs for Linode or the Linode API documentation, as the capabilities might change over time and the proper module might need to be installed.

    For more detailed information on Pulumi's Kubernetes integration, you can consult Pulumi's Kubernetes provider documentation: Pulumi Kubernetes Provider. For specifics about deploying Helm charts with Pulumi, the Helm Chart resource documentation is a valuable resource: Pulumi Helm Chart Resource.
