1. Deploy the postgres-instance helm chart on Azure Managed Openshift Service


    To deploy a postgres-instance Helm chart on an Azure Managed OpenShift Service using Pulumi, you need to take several steps:

    1. Set up an Azure Managed OpenShift Cluster: This is your Kubernetes-compatible environment where the application will run. We will use the azure-native.containerservice.OpenShiftManagedCluster class to create this.

    2. Install the Helm Chart: After setting up the OpenShift cluster, you'll use the kubernetes.helm.v3.Chart class from Pulumi's Kubernetes provider to deploy the postgres-instance chart.

    Here's how you could write your Pulumi program in TypeScript to accomplish this:

    Step-by-step breakdown:

    1. Set up an OpenShift Managed Cluster:

    First, import the necessary Pulumi libraries and then declare your OpenShift cluster. Note that a real deployment would require you to have proper SSH keys, a domain, and other mandatory configuration settings in place, which are represented here as placeholders for the purposes of this example.

    2. Deploy the Helm Chart:

    With the cluster set up, next instantiate a Helm chart resource that points to the postgres-instance chart. You'll specify the repository (if it's a custom one), the chart name, and any values that need to be overridden in the values parameter.


    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); // Create an Azure Managed OpenShift cluster const cluster = new azure_native.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { /* Replace the below properties with actual values */ // resourceName: "myOpenShiftCluster", // resourceGroupName: resourceGroup.name, location: "East US", // Be sure to choose a location that supports OpenShift openShiftVersion: "4.3", // Use a supported OpenShift version networkProfile: { vnetCidr: "", }, masterPoolProfile: { count: 3, // Number of masters vmSize: "Standard_D4s_v3" // Size of the VM instances }, // Other required configurations... // This example is simplified, more configuration will be needed in a real-world scenario // See the documentation: https://www.pulumi.com/registry/packages/azure-native/api-docs/containerservice/openshiftmanagedcluster/ }); // Create a provider for the above OpenShift cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeconfigRaw, // kubeconfig is obtained from the OpenShift Managed Cluster }); // Deploy a postgres-instance Helm chart const postgresChart = new k8s.helm.v3.Chart("postgres-instance", { chart: "postgresql", version: "9.1.1", // Use the version of the chart you want to deploy fetchOpts: { repo: "https://charts.bitnami.com/bitnami" }, // Specify the Helm chart repository here, if it's not a default one // values: { /* Custom values for PostgreSQL */ }, }, { provider: k8sProvider }); // Specify the provider to ensure Helm uses the correct cluster // Export the kubeconfig to access the cluster export const kubeconfig = cluster.kubeconfigRaw; // When running `pulumi up`, Pulumi will do the following: // 1. Provision an Azure Managed OpenShift Service cluster // 2. Set up a Kubernetes provider associated with the new cluster // 3. Use the Kubernetes provider to install a postgres-instance Helm chart to the cluster


    The above program does the following:

    • It starts by creating a new resource group in Azure to contain all resources.
    • Next, it provisions a new Azure Managed OpenShift cluster with necessary parameters like location, OpenShift version, network profile, and master pool profile.
    • The kubeconfig for managing the Kubernetes resources within the OpenShift cluster is then obtained from the cluster resource itself.
    • A Kubernetes provider is then set up using this kubeconfig which allows Pulumi to communicate with your OpenShift cluster.
    • Using this provider, the postgres-instance Helm chart is deployed. The chart and version parameters are given to point to the correct Helm chart, and optional values parameters can be used to customize the PostgreSQL deployment.
    • Lastly, the kubeconfig string is exported. This allows you to access the cluster with kubectl or any Kubernetes-compatible tooling.

    What's Next:

    You need to run pulumi up within the Pulumi project directory to preview and deploy these changes. Pulumi will automatically handle the creation of resources in the correct
