1. Deploy the mysql-exporter helm chart on Opensshift


    Deploying a Helm chart to an OpenShift cluster through Pulumi involves several steps. First, you need to ensure that you have configured Pulumi to communicate with your OpenShift cluster. Then, you can use the kubernetes.helm.v3.Chart resource to deploy the mysql-exporter Helm chart to the cluster.

    Below is a detailed Pulumi program in TypeScript that illustrates these steps.

    1. Set up your OpenShift cluster: Ensure your ~/.kube/config is pointing to the correct OpenShift cluster, or use the KUBECONFIG environment variable.

    2. Create a new Pulumi project: Either use an existing Pulumi project or create a new one with pulumi new.

    3. Write the Pulumi program: Write the TypeScript code to deploy the mysql-exporter Helm chart.

    Here is a Pulumi TypeScript program that deploys the mysql-exporter Helm chart:

    import * as k8s from '@pulumi/kubernetes'; // Define the Helm chart, version, and values const chartName = "mysql-exporter"; const chartVersion = "1.0.0"; // replace with your desired chart version const chartValues = { // specify your chart values here }; // Create a new Helm chart instance in the desired namespace const mysqlExporterChart = new k8s.helm.v3.Chart("mysql-exporter-chart", { chart: chartName, version: chartVersion, namespace: "default", // specify the namespace where you want to deploy the chart values: chartValues, fetchOpts:{ repo: "https://helm-charts.example.com/", // replace with the actual MySQL exporter Helm chart repository }, // You might need additional options if the Helm chart depends on CRDs skipAwait: false, // set to "true" if you are deploying CRDs }); // Export the URL of the MySQL Exporter service export const exporterUrl = mysqlExporterChart.getResourceProperty("v1/Service", "mysql-exporter-service", "status.url");

    Make sure to customize the chartValues and the chart repository URL (repo) with the actual values you intend to use. The program defines a reference to a Helm chart named mysql-exporter-chart and specifies its version and any custom values that configure the chart. In the case of the mysql-exporter, you'd define various settings such as service monitor configuration, exporter configuration, and the Prometheus Operator.

    This program will deploy the MySQL exporter chart into the default namespace. If your OpenShift cluster requires a specific namespace for deployments, make sure you replace "default" with the correct namespace name.

    When you run the program with pulumi up, Pulumi performs the deployment, creating all the necessary resources on your OpenShift cluster to get the mysql-exporter running. After deployment, Pulumi outputs the URL of the MySQL Exporter service if it's externally accessible.

    Remember to always review the values section of the Helm chart, which you can obtain from the chart repository or its documentation, to configure the chart according to your needs.
