1. Deploy the kafka-topics-ui helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the kafka-topics-ui helm chart on Oracle Kubernetes Engine (OKE), you will need to set up a few things:

    1. Create an OKE cluster if you haven't already done so.
    2. Install and set up Helm in your local environment.
    3. Configure Pulumi to use your OCI (Oracle Cloud Infrastructure) account and the Kubernetes context for your OKE cluster.
    4. Write a Pulumi program to deploy the kafka-topics-ui chart using the Pulumi Kubernetes provider.

    Below is a Pulumi program written in TypeScript that performs the Helm chart deployment. This program assumes that you have an OKE cluster up and running and that your local environment is set up with the necessary OCI and Kubernetes configurations. Ensure that your Pulumi stack is correctly configured to access your OCI resources and Kubernetes cluster context.

    First ensure the following prerequisites:

    • Pulumi CLI installation and authentication configured for OCI.
    • Helm CLI installed locally.
    • Oracle Kubernetes Engine (OKE) cluster running.
    • kubectl configured with access to your OKE cluster.
    • Your chosen namespace exists in your cluster, or adjust the program to create one.

    Here's a detailed explanation of the program:

    • We import the required pulumi and kubernetes modules.
    • We use the kubernetes.helm.v3.Chart class from the Pulumi Kubernetes provider to deploy a Helm chart.
    • We specify the chart name, repository, and version. In this case, we are deploying kafka-topics-ui, which would typically be available from a known Helm chart repository (not specified here since this is a hypothetical situation, where you must substitute the actual repository URL).
    • We set the release name and namespace where the Helm chart will be deployed. You may need to change 'kafka-topics-ui' and 'default' to the appropriate release name and namespace for your use case.

    Here's the program that accomplishes the Helm chart deployment:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; const chartName = "kafka-topics-ui"; const chartVersion = "1.0.0"; // Replace with the actual chart version you want to deploy const releaseName = "kafka-topics-ui-release"; const namespace = "default"; // Replace with the namespace you want to deploy into // Deploy the kafka-topics-ui Helm chart to the OKE cluster const kafkaTopicsUiChart = new kubernetes.helm.v3.Chart(releaseName, { // The repository URL for the kafka-topics-ui Helm chart, replace with the actual URL chart: "kafka-topics-ui", version: chartVersion, fetchOpts: { // Specify the repository where the Helm chart is located if required // repo: "https://example.com/helm-charts", }, namespace: namespace, }, { // Important: Make sure to provide the correct provider that points to your OKE cluster provider: /* Your Kubernetes provider’s configuration here, e.g., new kubernetes.Provider("oke-k8s-provider", { kubeConfig: "your-kubeconfig-here" }) */ }); // Optional: Export the status URL, if your Helm chart provides one export const kafkaTopicsUiStatusUrl = pulumi.interpolate`http://${kafkaTopicsUiChart.getResourceProperty("v1/Service", `${releaseName}-${chartName}`, "status.loadBalancer.ingress[0].hostname")}`;

    Make sure to replace placeholder values such as chartVersion, namespace, and repo with actual values pertaining to your deployment. Also, configure the Kubernetes provider with the appropriate context or kubeconfig to communicate with your OKE cluster.

    This program does not handle the creation of OKE clusters or OCI resources. Should you need to create an OKE cluster as part of your process, you would use the appropriate OCI Pulumi provider and resources, such as oci.ContainerEngine.Cluster.

    After the program has been written, you would run it using the Pulumi CLI:

    # Log in to Pulumi pulumi login # Create a new stack for your deployment (if you haven't already) pulumi stack init [stack name] # Deploy the Helm chart pulumi up

    Running pulumi up will prompt you for confirmation before applying the changes. Once confirmed, Pulumi will deploy the Kafka Topics UI to your Oracle Kubernetes Engine cluster. After the deployment, if the chart exposes any services with external endpoints, the URL will be exported and displayed by Pulumi.
