1. Deploy the prometheus-operator-csv helm chart on Opensshift


    To deploy the Prometheus Operator Helm chart on OpenShift, we'll use the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package. This resource represents a Helm chart and encapsulates all Kubernetes resources defined by the chart.

    First, you need to install the Pulumi CLI and set up your OpenShift/Kubernetes environment appropriately. Once that's in place, you can use the Pulumi program below to deploy the Prometheus Operator Helm chart. This program assumes that you have the openshift-client tool configured to interact with your OpenShift cluster and that you also have helm command-line tools installed and configured.

    Let's go through the steps of the program:

    1. Initialization: We start by importing necessary modules and creating a new Pulumi project.

    2. Chart Deployment: We instantiate a Chart resource representing the Prometheus Operator chart. We'll specify the chart name, version (if required), and the repository where the chart can be found. We'll also specify the namespace where we want the chart to be deployed.

    3. Configuration: If you want to provide a custom configuration for the Helm chart, you can pass a values object that overrides any of the default chart values.

    4. Execution: When you run pulumi up, Pulumi will reach out to your cluster and deploy the chart.

    Here's what the program looks like in TypeScript:

    import * as k8s from "@pulumi/kubernetes"; // Create a new Kubernetes project. const projectName = "prometheus-operator-openshift"; // The Prometheus Operator Helm chart details. const chartName = "prometheus-operator"; const chartVersion = "9.3.1"; // Specify the version you want to deploy const repositoryOpts = { repo: "https://prometheus-community.github.io/helm-charts" }; // Namespace where the chart will be deployed. const namespace = "monitoring"; const prometheusOperator = new k8s.helm.v3.Chart(projectName, { chart: chartName, version: chartVersion, fetchOpts: repositoryOpts, namespace: namespace }, { // If the OpenShift environment does not allow Helm to deploy into the namespace directly, // you might need to customize the provider to use the OpenShift client configuration. // Additional options can be included in the provider configuration if needed. }); // To perform actions on the Kubernetes cluster, Pulumi requires access to the kubeconfig file // and the @pulumi/kubernetes provider will use the current context in your kubeconfig. // Make sure you are logged into the correct context using the OpenShift client tool `oc` // before running `pulumi up`. // Running `pulumi up` will deploy the Prometheus Operator Helm chart into your OpenShift cluster.

    Remember to replace the chartVersion with the specific version of the Prometheus Operator chart you want to deploy. If you don't specify a version, the latest version will be deployed.

    To apply this deployment to your OpenShift cluster, you would execute the Pulumi CLI command pulumi up in the directory containing this code. Pulumi would then perform the deployment according to the details provided in the code.

    Pulumi's output will provide you with detailed logs of the deployment process. If successful, you will see a summary of the resources created by the Helm chart in your terminal.
