1. Deploy the prometheus-operator-mixin helm chart on Kubernetes


    To deploy the prometheus-operator-mixin Helm chart on Kubernetes using Pulumi, you need to follow several steps. Firstly, ensure you have a Kubernetes cluster and kubectl access properly set up as Pulumi will use the current context to deploy resources. Secondly, you need to familiarize yourself with Pulumi's Chart resource from the Pulumi Kubernetes package, which allows you to deploy Helm charts.

    The Chart resource is a high-level component that encapsulates a collection of Kubernetes resources represented by a Helm Chart. When you instantiate a Chart resource in Pulumi, it will use Helm to fetch and expand the chart into the set of Kubernetes resources it represents. Then, Pulumi will deploy these resources onto the cluster.

    Below is a Pulumi program written in TypeScript that demonstrates how to deploy the prometheus-operator-mixin Helm chart. In the example, replace "example-namespace" with the Kubernetes namespace where you want to deploy the chart.

    import * as k8s from "@pulumi/kubernetes"; // Define the Helm chart version and other related values as per your requirements. const prometheusOperatorMixinChart = new k8s.helm.v3.Chart("prometheus-operator-mixin", { chart: "prometheus-operator-mixin", version: "9.3.1", // Specify the version of the chart you want to deploy fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts", }, namespace: "example-namespace", // Define any custom values you want to pass to the chart values: { // These values are just examples. Replace them with valid configuration for prometheus-operator-mixin. grafana: { enabled: true, }, prometheus: { enabled: true, }, // Add any additional values you need to configure }, }); // Export the endpoint of Prometheus if exposed via service or ingress export const prometheusEndpoint = prometheusOperatorMixinChart.getResourceProperty("v1/Service", "example-namespace/prometheus", "status").apply(s => s.loadBalancer.ingress[0].hostname || s.loadBalancer.ingress[0].ip);

    In this program:

    • We import the @pulumi/kubernetes package, which contains helpers for deploying Kubernetes resources.
    • We create a new Chart resource, which represents the Prometheus Operator Mixin Helm chart. The essential parameters are:
      • chart: The name of the Helm chart.
      • version: The specific chart version to deploy.
      • fetchOpts: An object that specifies the Helm repository where the chart is located.
      • namespace: Kubernetes namespace where the chart will be deployed.
      • values: An object that allows you to specify custom values to configure the chart.
    • We export a resource property prometheusEndpoint, which dynamically retrieves the load balancer's hostname or IP address for the Prometheus service once it's available after deployment.

    This code should be part of a Pulumi program, and you would typically run pulumi up to deploy this Helm chart to your cluster. Ensure to provide the correct chart version and repository for the prometheus-operator-mixin chart and configure the values based on your needs, as Helm charts can have extensive configuration options.

    Before running this program, make sure to install the Pulumi CLI, and select or create a Pulumi stack that corresponds to your Kubernetes environment. After running the program with pulumi up, Pulumi will print the output of prometheusEndpoint that can be used to access Prometheus once the deployment is complete.
