1. Deploy the influxdb-backup helm chart on Azure Managed Openshift Service


    In order to deploy an influxdb-backup Helm chart on an Azure Managed OpenShift Service using Pulumi, you will follow a set of steps within a Pulumi program written in TypeScript. First, let me explain the key components that we will use:

    1. Azure Managed OpenShift Service: Azure offers an OpenShift service as a fully managed application platform, powered by Kubernetes. We will deploy an instance of this service using Pulumi's azure-native.containerservice.OpenShiftManagedCluster component.

    2. Helm Chart: Helm is a package manager for Kubernetes, which allows you to define, install, and upgrade even the most complex Kubernetes applications. Helm charts are the packages that Helm uses for this purpose.

    3. Pulumi Kubernetes Provider: To deploy Helm charts using Pulumi, we will use Pulumi's Kubernetes provider. Specifically, the kubernetes.helm.v3.Chart resource will allow us to define and install the Helm chart.

    Here is a Pulumi program that deploys the influxdb-backup Helm chart on an Azure Managed OpenShift Service.

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; import * as azuread from "@pulumi/azuread"; // Create an Azure Resource Group const resourceGroup = new azure.resources.ResourceGroup("myResourceGroup"); // Azure Managed OpenShift Cluster const openShiftCluster = new azure.containerservice.OpenShiftManagedCluster("myOpenShiftCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, openShiftVersion: "4.3", // specify your desired OpenShift version networkProfile: { vnetCidr: "", }, masterPoolProfile: { count: 3, // number of master nodes vmSize: "Standard_DS3_v2", // size of master nodes }, agentPoolProfiles: [{ name: "agentpool", count: 3, // number of worker nodes vmSize: "Standard_DS3_v2", // size of worker nodes osType: "Linux", }], // Set the authentication to your preference (using service principal here for example) authProfile: { identityProviders: [{ name: "Azure AD", provider: { kind: "AADIdentityProvider", clientId: "<AAD-APP-CLIENT-ID>", secret: "<AAD-APP-SECRET>", tenantId: "<AAD-TENANT-ID>", }, }], }, }); // Using Pulumi's Kubernetes provider to deploy the influxdb-backup Helm chart const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: openShiftCluster.kubeconfig.apply(JSON.stringify), }); const influxdbBackupChart = new k8s.helm.v3.Chart("influxdb-backup", { chart: "influxdb-backup", version: "1.1.0", // specify desired chart version namespace: "default", // specify namespace where chart will be installed }, { provider: k8sProvider }); // Export the kubeconfig to access the OpenShift cluster export const kubeconfig = openShiftCluster.kubeconfig;

    Here's what each part of the script does:

    • Resource Group: A container that holds related resources for an Azure solution.

    • OpenShift Managed Cluster: Sets up an OpenShift cluster in the specified resource group and location. You'll adjust openShiftVersion, vmSize, and count of nodes to your preferences. Authentication is set up pointing to an Azure Active Directory application.

    • Kubernetes Provider: This is the Pulumi provider instance that connects to our OpenShift cluster.

    • Helm Chart: We define the influxdb-backup Helm chart to be deployed, including the chart name, version, and namespace.

    To use this program, you'll need to replace <AAD-APP-CLIENT-ID>, <AAD-APP-SECRET>, and <AAD-TENANT-ID> with your actual Azure AD application details. After that, you can execute the script using Pulumi CLI to deploy these services.

    Remember, the kubeconfig of the created OpenShift cluster is exported, which you'll use to interact with your cluster using tools like kubectl or OpenShift's oc.

    Running the Pulumi program will result in Pulumi creating and managing the requested cloud resources for you. It will perform create, update, and delete operations as needed when you add, change, or remove resources in your Pulumi program.
