1. Deploy the kafka-topics-ui helm chart on Rancher


    To deploy the kafka-topics-ui helm chart on a Rancher managed Kubernetes cluster using Pulumi, you will first need to set up a Rancher Kubernetes cluster and import that context into Pulumi. For this purpose, Pulumi provides a provider named rancher2 which enables us to work with Rancher resources.

    Once you have the Rancher cluster set up and available, you can deploy the kafka-topics-ui chart, similar to how you would use Helm, but with the added benefits of Pulumi's infrastructure as code approach. Below is a TypeScript program that outlines these steps.

    I'll explain each part of the program:

    1. Import statements: These include the needed Pulumi packages.
    2. Kubernetes Provider: We set up a Kubernetes provider to interact with the Rancher Kubernetes cluster.
    3. Deployment of the Helm chart: We create a new Helm chart resource which indicates Pulumi to deploy the kafka-topics-ui helm chart using the provided configuration.

    Note: Before you run this code, you will need the following:

    • Pulumi CLI installed and set up to use with Rancher.
    • Access to a Rancher Kubernetes cluster and the kubeconfig file for said cluster.

    Here's the Pulumi code for deploying kafka-topics-ui on Rancher:

    import * as pulumi from '@pulumi/pulumi'; import * as rancher2 from '@pulumi/rancher2'; import * as k8s from '@pulumi/kubernetes'; // Retrieving and setting Rancher's kubeconfig const kubeconfig = new pulumi.Config().requireSecret("kubeconfig"); // Setting up a Kubernetes provider to interact with the Rancher cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // The Helm chart for kafka-topics-ui const kafkaTopicsUIChart = new k8s.helm.v3.Chart("kafka-topics-ui", { chart: "kafka-topics-ui", version: "1.0.0", // specify the version if necessary // You would specify the repository options if the Helm chart is not from stable repository // repositoryOpts: { // repo: "http://helm-repository-url/" // }, // Values from the kafka-topics-ui Helm chart's values.yaml file values: { // Specify your values for the kafka-topics-ui chart here }, }, { provider: k8sProvider }); // Export the resources' details if required export const kafkaTopicsUIChartName = kafkaTopicsUIChart.metadata.apply(metadata => metadata.name); export const kafkaTopicsUIChartStatus = kafkaTopicsUIChart.status.apply(status => status);

    Please replace "1.0.0" with the version you wish to use. Additionally, if the chart is not in the standard repository, make sure to provide the appropriate repository URL.

    You can find the details about configuring the values by looking at the values.yaml file provided by the Kafka Topics UI Helm chart. These values allow you to customize the deployment to match your needs, such as setting up the chart to connect to your Kafka instance and any other necessary configurations.

    Once you have this program ready, you can use pulumi up to deploy the chart to your Rancher-managed Kubernetes cluster. Pulumi will present a preview of the deployment, and upon confirmation, it will execute the deployment. After the deployment, Pulumi will output the details of the resources it has created or modified.
