Deploy the kafdrop helm chart on Azure Managed Openshift Service
TypeScriptTo deploy the Kafdrop Helm chart on Azure Managed OpenShift Service using Pulumi, you will follow multiple steps:
-
Set up an Azure Managed OpenShift cluster: You'll be using the
azure-native.containerservice.OpenShiftManagedCluster
resource to create an Azure Red Hat OpenShift cluster. -
Deploy a Helm Chart: After setting up the cluster, you'll deploy your Helm chart using the
kubernetes.helm.v3.Chart
resource, which is a Pulumi resource for deploying Helm charts to a Kubernetes cluster.
In the code below, I'll demonstrate how to accomplish both steps in a single Pulumi program.
Detailed Explanation:
- Create an Azure Managed OpenShift Cluster: We define an OpenShift managed cluster in a specific location with the necessary profiles for authentication, networking, and agent pool configurations.
- Install Kafdrop using a Helm Chart: We declare a Helm chart as a resource, specifying the chart name - in this case,
kafdrop
(ensure the correct chart name and repository URL). The Helm chart resource will be deployed into the OpenShift cluster we created. Kafdrop is a web UI for viewing Kafka topics and browsing consumer groups, so we will be specifying Kafka-related configurations in the values.
Note: Before running the Pulumi program, ensure you have the Pulumi CLI installed and configured with Azure credentials, Helm CLI installed locally,
kubectl
configured to access the Azure Managed OpenShift Service, and that the Openshift CLI (oc
) is installed which might be needed for some Openshift specific configurations.Now, let's write the Pulumi program in TypeScript:
import * as pulumi from "@pulumi/pulumi"; import * as azureNative from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Replace these variables with the actual values you want to use const location = "East US"; // Azure region const resourceGroupName = "kafdropResourceGroup"; // Azure resource group const openshiftClusterName = "kafdropOpenShiftCluster"; // Name for the OpenShift Cluster const openShiftVersion = "4.3.0"; // Specify the OpenShift version // Add other configurations such as networking, authentication, etc., as needed. // Create an Azure resource group const resourceGroup = new azureNative.resources.ResourceGroup(resourceGroupName, { location: location, }); // Create the Azure Managed OpenShift cluster const openshiftCluster = new azureNative.containerservice.OpenShiftManagedCluster(openshiftClusterName, { resourceGroupName: resourceGroup.name, location: resourceGroup.location, // Defining other properties like network profile, master and agent pools, etc. openShiftVersion: openShiftVersion, // Ensure you specify the right OpenShift version you want to deploy // Specify other properties as needed }); // Kubernetes Provider to interact with the OpenShift cluster const k8sProvider = new k8s.Provider("k8sProvider", { // Assuming 'kubeconfig' is obtained from the Openshift cluster after creation kubeconfig: openshiftCluster.kubeconfig.apply(kubeconfig => kubeconfig), }); // Now deploying the Kafdrop Helm chart to the OpenShift cluster const kafdropChart = new k8s.helm.v3.Chart("kafdrop", { chart: "kafdrop", // Replace with the specific version you need and repository if not using the stable channel version: "latest", // Specify the version of the Kafdrop chart fetchOpts: { repo: "https://some-helm-repo-url/", // Specify the correct Helm repo URL where Kafdrop chart is hosted }, values: { // Specify your values for the Kafdrop chart as needed }, }, { provider: k8sProvider }); // Export the OpenShift cluster's kubeconfig and Kafdrop service endpoint export const kubeconfig = openshiftCluster.kubeconfig; export const kafdropServiceEndpoint = kafdropChart.getResourceProperty("v1/Service", "kafdrop", "status") .apply(status => status.loadBalancer.ingress[0].ip);
How to Run the Program:
- Step 1: Save the above code in a file named
index.ts
. - Step 2: Run
pulumi up
to preview and deploy the resources described in the program.
What Happens When You Run the Program:
- Pulumi will prompt you to confirm the actions before making changes to your cloud infrastructure.
- Upon confirmation, Pulumi will provision an Azure Red Hat OpenShift cluster.
- After the cluster is provisioned, Pulumi will deploy the Kafdrop Helm chart to the OpenShift cluster.
- The
kubeconfig
and the service endpoint to access Kafdrop will be exported as output.
After the Pulumi deployment is complete, you can use the
kubeconfig
to configurekubectl
or the Openshift clientoc
to interact with your cluster, and use the service endpoint to access the Kafdrop UI in a web browser.-
