1. Deploy the prometheus-federation helm chart on Linode Kubernetes Engine

    TypeScript

    In order to deploy the Prometheus Federation Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, we will take these steps:

    1. Set up a new Pulumi project and stack for your Linode infrastructure.
    2. Import the necessary Pulumi packages for interacting with Kubernetes and Helm.
    3. Ensure that you have access to a Linode Kubernetes cluster and that you are authenticated to your Linode account.
    4. Create a Pulumi Kubernetes provider configured to interact with your LKE cluster.
    5. Use the kubernetes.helm.v3.Chart resource to deploy the Prometheus Federation Helm chart to your LKE cluster.
    6. Define any required Helm values that the Prometheus Federation chart requires using the values attribute.
    7. Export any necessary outputs, such as the service endpoint for accessing Prometheus.

    Before we proceed with the Pulumi TypeScript program, make sure you have Pulumi CLI installed and configured with Linode access credentials. You should also have kubectl configured with the context set to your Linode Kubernetes cluster.

    Below is a Pulumi TypeScript program that will deploy the Prometheus Federation Helm chart onto an LKE cluster:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a new Kubernetes provider instance using the context of your LKE cluster // This utilizes the default kubeconfig file located at `~/.kube/config` // This also assumes that your kubeconfig is already set with the context of your LKE cluster const k8sProvider = new k8s.Provider("lkeProvider", { kubeconfig: pulumi.output(pulumi.secret("<YOUR_KUBECONFIG_CONTENTS>")).apply(c => c), }); // Step 2: Deploy Prometheus Federation Helm chart using `kubernetes.helm.v3.Chart` resource // Make sure you have the correct repository URL and chart name. // Replace `values` with the actual configuration needed by the chart. const prometheusFederation = new k8s.helm.v3.Chart("prometheus-federation", { chart: "prometheus-federation", version: "<CHART_VERSION>", // Use the desired chart version fetchOpts: { repo: "https://helm-repository-url/where/chart-is-located", // Replace with the actual Helm repository URL }, values: { // Define any Helm chart values here, such as: // service: { // type: "LoadBalancer" // } // Customize these values based on the requirements of the Prometheus Federation chart }, }, { provider: k8sProvider }); // Step 3: Export any necessary outputs // For example, if you have a LoadBalancer service and you want to output the external IP: export const prometheusEndpoint = prometheusFederation.getResourceProperty("v1/Service", "prometheus-federation-service", "status") .apply(status => status.loadBalancer.ingress[0].ip);

    Replace <YOUR_KUBECONFIG_CONTENTS> with the actual contents of your kubeconfig file, or another secure way to provide this sensitive information to Pulumi. Always make sure to treat credentials like your kubeconfig as secret.

    Customize the values property with the necessary configuration details required by the Prometheus Federation Helm chart. You'll need to consult the chart's documentation for the specific configuration options it supports.

    After defining your program, run pulumi up to deploy your resources to your Linode Kubernetes cluster. The program will show you a preview of the resources that will be created and ask for confirmation before proceeding.

    If the program successfully runs, it will deploy the Prometheus Federation Helm chart to your LKE cluster, and the prometheusEndpoint will be the entry point to access Prometheus service if it is exposed as a LoadBalancer.

    Note: The Helm chart, version, repository URL, and values will vary based on the actual Helm chart details for Prometheus Federation which you want to deploy. Make sure to retrieve the correct information from the Helm chart's repository or documentation.
