Deploy the sumologic-fluentd helm chart on Azure Managed Openshift Service

Question

Pulumi · Accepted Answer

To deploy the Sumo Logic FluentD Helm chart on an Azure Managed OpenShift Service, you will need to perform two key actions:

Provision an Azure Red Hat OpenShift Cluster.
Deploy the Helm chart to this cluster.

We will use Pulumi with TypeScript for this automation. Pulumi allows us to define infrastructure as code using programming languages like TypeScript. For this task, we will use the azure-native package to deploy an Azure Managed OpenShift Service, known as Azure Red Hat OpenShift, and the kubernetes package to deploy the Helm chart.

The first resource, azure-native.redhatopenshift.OpenShiftCluster, is for provisioning the OpenShift cluster. The second one, kubernetes.helm.sh/v3.Chart, is for deploying Helm charts on a Kubernetes cluster.

In the Pulumi program below, I assume that you have Azure credentials configured properly, as well as kubectl and Helm installed on the machine where the deployment is done. Moreover, Pulumi SDK and CLI need to be installed.

Here's how to accomplish the deployment:

import * as pulumi from "@pulumi/pulumi";
import * as azureNative from "@pulumi/azure-native";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Provision an Azure Red Hat OpenShift Cluster.
const openshiftCluster = new azureNative.redhatopenshift.OpenShiftCluster("myOpenShiftCluster", {
    resourceGroupName: "myResourceGroup",
    location: "eastus",
    clusterProfile: {
        pullSecret: "<Your OpenShift Pull Secret>", // Obtain from Red Hat OpenShift
        domain: "example",
        version: "4.7.0", // Specify your desired OpenShift version
    },
    masterProfile: {
        vmSize: "Standard_D8s_v3",
        diskEncryptionSetId: "<Your Disk Encryption Set ID>", // For encrypted storage
    },
    networkProfile: {
        podCidr: "10.2.0.0/16",
        serviceCidr: "10.3.0.0/16",
    },
    workerProfiles: [{
        name: "worker",
        vmSize: "Standard_D8s_v3",
        diskSizeGB: 128,
        subnetId: "<Your Subnet ID>", // use the ID of an existing or a new subnet
        count: 3,
    }],
    servicePrincipalProfile: {
        clientId: process.env.AZURE_CLIENT_ID,
        clientSecret: process.env.AZURE_CLIENT_SECRET,
    },
});

// Step 2: Deploy the Helm chart to the OpenShift cluster.
// First, we'll need to set up a provider that uses the Kubernetes cluster credentials.
const openshiftProvider = new k8s.Provider("openshiftProvider", {
    kubeconfig: openshiftCluster.kubeconfig.apply(JSON.stringify),
});

// Now, deploy the Sumo Logic FluentD Helm chart on the OpenShift cluster using the provider we've set up.
const sumologicFluentd = new k8s.helm.v3.Chart("sumologic-fluentd", {
    chart: "sumologic-fluentd",
    version: "1.0.0", // Use the correct version of the Helm chart
    fetchOpts: {
        repo: "https://sumologic.github.io/sumologic-kubernetes-collection/", // Use the proper Helm repo URL
    },
    values: {
        // Supply any necessary values here.
        // You will need to refer to the particular Helm chart's documentation for these.
    },
}, { provider: openshiftProvider });

// Export the OpenShift cluster's kubeconfig as an output for easy access.
export const kubeconfig = openshiftCluster.kubeconfig;

This Pulumi program performs these actions:

Provisions an Azure Red Hat OpenShift Cluster: The azure-native.redhatopenshift.OpenShiftCluster resource is used to create the OpenShift cluster in Azure. You would need to replace placeholder strings with real values, such as the location, domain, OpenShift version, VM size, disk encryption set ID, subnet ID, and service principal credentials. The OpenShift pull secret can be obtained from Red Hat OpenShift.
Deploys the Sumo Logic FluentD Helm Chart: The k8s.helm.v3.Chart resource is responsible for deploying the Helm chart to the OpenShift cluster. It refers to the sumologic-fluentd chart and specifies the version and repository URL. Depending on the Helm chart requirements, you may need to fill in the values with appropriate configuration for the deployment.
Exports the Kubeconfig: The kubeconfig output will give you the necessary information to access your OpenShift cluster via kubectl.

If you have questions about specific version numbers, configurations, or additional Azure and/or OpenShift properties, they should be addressed according to your unique needs and the official documentation. Always refer to the official Pulumi documentation for detailed information on the resources available and how to use them.
