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


    To deploy the Prometheus Operator Mixin Helm chart on an OpenShift cluster, you need to follow a few steps that involve Pulumi's Kubernetes provider and the Helm Chart resource.

    The Pulumi kubernetes.helm.v3.Chart resource allows you to deploy a Helm chart to a Kubernetes cluster. Helm is a package manager for Kubernetes that facilitates the deployment and management of applications.

    To begin, you need to set up your OpenShift cluster and ensure you have Pulumi installed and set up with access to your Kubernetes cluster.

    The program will follow these steps:

    1. Import the necessary Pulumi and Kubernetes packages.
    2. Create a new Kubernetes Helm Chart resource for Prometheus Operator Mixin.

    Before starting with the code, it's important to ensure that you have the Helm repository for Prometheus Operator added to your Helm configuration. You can do this by running the following command outside of Pulumi:

    helm repo add prometheus-community https://prometheus-community.github.io/helm-charts helm repo update

    Below is a TypeScript program that deploys the Prometheus Operator Mixin Helm chart on OpenShift:

    import * as k8s from "@pulumi/kubernetes"; const prometheusOperatorMixinChart = new k8s.helm.v3.Chart("prometheus-operator-mixin", { chart: "kube-prometheus-stack", version: "X.Y.Z", // replace with the specific chart version you want to deploy namespace: "monitoring", // ensure the namespace exists in your cluster fetchOpts: { repo: "https://prometheus-community.github.io/helm-charts", }, // You can specify the values according to your needs, this may include custom configurations. // This is an example of setting a simple value, but typically this would be a more complex object. // For the full list of configurable values, refer to the chart's documentation. values: { // For example, if you need to expose the Prometheus server, // you can set `service.type` to "ClusterIP" or "NodePort". prometheus: { prometheusSpec: { // You can customize it according to your requirements. }, }, // Include additional custom configuration as required. }, }); // Optionally, you can export the Helm release status export const releaseStatus = prometheusOperatorMixinChart.status;

    A few things to note in the code above:

    • Replace the X.Y.Z with the version number of the kube-prometheus-stack chart you want to use. You can find the latest version in the Helm chart repository or the documentation.
    • The namespace should be set to the namespace where you want to install the Prometheus operator. Make sure this namespace exists on your OpenShift cluster.
    • In the values object, you can customize the deployment according to your needs. You might want to look up the configuration options in the official kube-prometheus-stack chart documentation for all available options.
    • The releaseStatus is an optional export, providing information about the deployment status of the Helm chart.

    Make sure you review and adjust the values section to conform to the specific requirements of your OpenShift cluster and Prometheus Operator configuration expectations. Once this program is deployed with Pulumi, it will create the resources defined by the kube-prometheus-stack Helm chart on your Kubernetes cluster.

    To execute the Pulumi program, run the following commands in the directory where the program file is located:

    pulumi stack init dev # Initializes a new stack called 'dev' (or use an existing one) pulumi up # Review and deploy the changes

    This will start the deployment process where Pulumi will show the changes that will be applied to your cluster. Confirm the changes, and Pulumi will deploy Prometheus Operator Mixin to your OpenShift cluster. After the deployment, Pulumi will output the status of the release if the releaseStatus is exported.
