1. Deploy the mysql-exporter helm chart on Azure Managed Openshift Service


    To deploy the mysql-exporter Helm chart on an Azure Managed OpenShift cluster using Pulumi, we need to carry out several steps. First, we have to create an Azure Managed OpenShift cluster, and then deploy the mysql-exporter Helm chart to this cluster. We'll accomplish this by writing a Pulumi program in TypeScript.

    Here's how we'll proceed:

    1. Setting Up the OpenShift Cluster: We need to provision an Azure Managed OpenShift cluster using the azure-native.containerservice.OpenShiftManagedCluster resource. Essential properties like resourceGroupName, location, and openShiftVersion must be provided to create the cluster.

    2. Deploying the Helm Chart: After the OpenShift cluster is up and running, we'll deploy the mysql-exporter using the kubernetes.helm.v3.Chart resource. This presumes that the Helm chart for mysql-exporter is available in a Helm repository. We'll specify the chart name, version (if not using the latest), and any custom values required for the MySQL exporter configuration.

    3. Accessing Kubernetes Resources: To interact with Kubernetes resources, Pulumi uses the Kubernetes provider, which needs to be configured with the appropriate kubeconfig. Since we're dealing with an OpenShift cluster managed by Azure, we would have to retrieve the kubeconfig for the cluster and provide it to the Kubernetes provider. Normally, this involves using the Azure CLI or Azure SDK to fetch the kubeconfig after cluster creation.

    Below is the Pulumi TypeScript program that executes the steps outlined above. Throughout the code, you'll find comments explaining each section and line.

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Placeholder values for required properties. Replace these with the actual values. const resourceGroupName = "myResourceGroup"; const location = "East US"; const openShiftVersion = "4.3.0"; const clusterName = "myOpenShiftCluster"; // Create an Azure Managed OpenShift cluster. const openshiftCluster = new azure_native.containerservice.OpenShiftManagedCluster(clusterName, { resourceGroupName: resourceGroupName, location: location, openShiftVersion: openShiftVersion, // Define other necessary properties like network profiles, agent pool profiles, etc. // Refer to Azure Managed OpenShift documentation for required and optional properties. }); // Since obtaining the kubeconfig from the OpenShift cluster is an operation that may require external calls, // we assume that the kubeconfig has been obtained and is available to use. // In a real-world scenario, we would programmatically fetch kubeconfig using Azure SDK or CLI commands. // For example: // `az aro list-credentials --name myCluster --resource-group myResourceGroup` // The kubeconfig content is then used to configure our Kubernetes provider. const kubeconfig = "<YOUR_KUBECONFIG_CONTENT>"; // Create a Kubernetes provider instance using the kubeconfig. const k8sProvider = new k8s.Provider("openshiftK8s", { kubeconfig: kubeconfig, }); // Deploy the `mysql-exporter` Helm chart on the Azure Managed OpenShift cluster. const mysqlExporterChart = new k8s.helm.v3.Chart("mysql-exporter", { // Provide specifics of the Helm chart repository and chart details. // If the chart is from a custom repository, specify the `repo` property with the repository URL. chart: "mysql-exporter", // You can specify the exact version of the chart you want to deploy. // If not provided, the latest version will be installed. // version: "x.y.z", // If additional configuration is required, specify `values`. // values: { /* Custom values for the mysql-exporter */ }, }, { provider: k8sProvider }); // Export the OpenShift Cluster's Managed Cluster ID and MySQL Exporter Service name // so that they can be easily accessed after deployment. export const openShiftManagedClusterId = openshiftCluster.id; export const mysqlExporterServiceName = mysqlExporterChart.getResource("v1/Service", "mysql-exporter", "default").metadata.name;

    This program assumes you have already configured Pulumi with appropriate Azure and Kubernetes credentials. Ensure that you replace placeholder values ("<YOUR_KUBECONFIG_CONTENT>", etc.) with actual configuration details relevant to your Azure and OpenShift environment.

    To run this Pulumi program:

    1. Save the code into a file with a .ts extension, for example, deployMysqlExporter.ts.
    2. Ensure you have Pulumi CLI installed and configured for use with Azure.
    3. Open a terminal and navigate to the directory containing the TypeScript file.
    4. Run pulumi up to initiate the deployment process.

    Pulumi will prompt you to review the resources that will be created and ask for confirmation before proceeding. Once confirmed, Pulumi applies the changes to Azure and deploys the mysql-exporter Helm chart. After successful deployment, you can use the exported variables to reference the OpenShift Managed Cluster ID and the MySQL Exporter Service name.
