1. Deploy the cloudwatch-agent-prometheus helm chart on Rancher

    TypeScript

    To deploy the cloudwatch-agent-prometheus Helm chart on a Rancher-managed Kubernetes cluster using Pulumi, we'll break down the task into a few steps:

    1. You need to set up an existing Rancher Kubernetes cluster or create a new one using Pulumi. For this explanation, we'll assume that you already have a Rancher Kubernetes cluster set up and managed by Rancher.

    2. You will need to interact with the cluster using Pulumi's Kubernetes provider, which allows you to deploy Helm charts.

    3. You will deploy the cloudwatch-agent-prometheus Helm chart. If the Helm chart you're referring to is hosted on a specific Helm repository, ensure that you add this repository to your cluster.

    Below is a Pulumi program written in TypeScript that demonstrates how you might deploy a Helm chart to a Rancher-managed Kubernetes cluster. Note that you would need to modify some of the properties to align with the specific configuration options of your Helm chart and Rancher setup.

    Make sure you have the following prerequisites met before you run the Pulumi program:

    • Pulumi CLI installed and set up.
    • Access to your Rancher Kubernetes cluster.
    • The relevant Kubernetes configuration file (kubeconfig) for your Rancher cluster that Pulumi will use to connect to your Kubernetes cluster.

    Here is a Pulumi program that demonstrates how to deploy a Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create a new Pulumi Kubernetes provider that uses the kubeconfig from your Rancher cluster const rancherK8sProvider = new k8s.Provider("rancher-k8s", { kubeconfig: `YOUR_RANCHER_CLUSTER_KUBECONFIG`, // Replace with your actual kubeconfig }); // Define the Helm chart repository, name, and version const chartRepo = "https://YOUR_HELM_CHART_REPO"; // Replace with your Helm chart repository URL const chartName = "cloudwatch-agent-prometheus"; // The Helm chart you want to deploy const chartVersion = "1.0.0"; // Use the correct chart version // Deploy the Helm chart to the cluster const prometheusChart = new k8s.helm.v3.Chart("cloudwatch-agent-prometheus-chart", { chart: chartName, version: chartVersion, fetchOpts: { repo: chartRepo, }, // Define any custom values you want to override in the Helm chart values: { // ... Insert custom values here }, }, { provider: rancherK8sProvider }); // Export the name of the chart export const chart = prometheusChart.metadata.name;

    Replace YOUR_RANCHER_CLUSTER_KUBECONFIG with your actual kubeconfig contents (it's usually recommended to use Pulumi Config to store sensitive information, but for the purpose of this introduction, the kubeconfig is directly embedded).

    Now, when you run this program with Pulumi (pulumi up), it will deploy the cloudwatch-agent-prometheus Helm chart to your Rancher-managed Kubernetes cluster.

    The k8s.Provider object is configured with your cluster's kubeconfig, which allows Pulumi to interact with your cluster. The k8s.helm.v3.Chart resource is responsible for deploying the Helm chart to the cluster provided in the configuration.

    This is a basic example; in reality, Helm charts often have many configuration options that you can set through the values property of the Chart resource. You’d replace the // ... Insert custom values here comment with the actual values required for your use case.

    Make sure to consult the Pulumi documentation for Kubernetes provider and Helm charts for more detailed information and advanced configurations.
