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


    To deploy the cloudwatch-agent-prometheus Helm chart on Kubernetes using Pulumi, we will use the @pulumi/kubernetes package. This package allows us to interact with Kubernetes resources within our Pulumi program. We will create a Chart resource, which represents a Helm chart deployment.

    Below is a Pulumi program written in TypeScript to accomplish your goal. This program assumes that you have Pulumi installed, have a Kubernetes cluster configured in your kubeconfig file, and have access to a Helm chart repository that hosts the cloudwatch-agent-prometheus chart.

    First, you would install the necessary dependencies by running the following commands:

    pulumi new kubernetes-typescript npm install @pulumi/kubernetes

    After setting up the TypeScript project and installing dependencies, you can write the following Pulumi program:

    import * as k8s from "@pulumi/kubernetes"; // Define the Helm chart by specifying the chart, version, and repository URL const cloudwatchAgentPrometheusChart = new k8s.helm.v3.Chart("cloudwatch-agent-prometheus", { chart: "cloudwatch-agent-prometheus", version: "x.y.z", // Replace with the desired chart version fetchOpts: { repo: "https://your-chart-repo/", // Replace with the Helm chart repository URL }, // Specify custom values for the chart values: { // You can specify any custom values that you want to override, for example: // image: { // repository: "amazon/cloudwatch-agent", // tag: "latest", // }, // For this example, we are assuming the chart already has default values set up // so we're not overriding anything. }, }, { provider: k8sProvider }); // Export the endpoint of the service export const endpoint = cloudwatchAgentPrometheusChart.getResourceProperty( "v1/Service", "cloudwatch-agent-prometheus", "status" ).apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);

    In the code above, the k8s.helm.v3.Chart class is used to represent and manage the Helm chart directly. You need to replace the placeholder values for the version and repo options with the version of the chart and the URL to the Helm repository hosting the cloudwatch-agent-prometheus chart, respectively. If you have custom configurations (values) for your Helm chart, you can set them in the values option.

    The endpoint export is an optional step, providing the means to access the service endpoint if the Helm chart creates a Kubernetes Service of type LoadBalancer.

    After writing this program, run the following command to deploy the Helm chart:

    pulumi up

    The pulumi up command will prompt you to confirm the deployment after showing you a preview of the changes. Once confirmed, Pulumi will deploy the Helm chart to your Kubernetes cluster.
