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


    To deploy a Kafka Connector Helm chart on Oracle Kubernetes Engine (OKE), you'll first need to ensure that you have an existing Kubernetes cluster running on OKE. If you already have one, you can proceed to install the Helm chart for the Kafka connector.

    Here's a step-by-step guide and Pulumi TypeScript program to accomplish this:

    1. Create a new Pulumi project: If you haven't already done so, make a new directory for your Pulumi project, and inside that directory, run pulumi new typescript.

    2. Setup Pulumi for OCI: Ensure you have an Oracle Cloud Infrastructure (OCI) account and have configured the Pulumi with the necessary OCI credentials.

    3. Install OCI Provider: You need to install the OCI provider plugin for Pulumi using npm or yarn. This allows you to work with OCI resources, including OKE.

    4. Install Kubernetes Provider: Install the Kubernetes provider plugin, which allows Pulumi to interact with your Kubernetes cluster.

    5. Define Kubernetes and Helm Resources: Use the kubernetes package to create a Helm Release. You will need to provide specific values like the chart version and any custom values you want to pass to the Helm chart for the Kafka connector.

    Below is the full TypeScript program for Pulumi:

    import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; import * as oci from '@pulumi/oci'; // Step 1: Create or select an existing OKE cluster // Assuming you have an existing OKE cluster, retrieve the kubeconfig const clusterOid = "your-existing-oke-cluster-oid"; // Replace with your actual cluster's OID const cluster = oci.containerengine.Cluster.get("okeCluster", clusterOid); // Retrieve the kubeconfig of the cluster. This requires your OCI configuration to be set up. const kubeconfig = cluster.kubeconfig(); // Step 2: Set up the Kubernetes provider to use the kubeconfig fetched from the OKE cluster const provider = new k8s.Provider("okeK8s", { kubeconfig, }); // Step 3: Deploy the Kafka Connector Helm chart on the OKE cluster const kafkaConnectorChart = new k8s.helm.v3.Chart("kafka-connector", { chart: "kafka-connector", version: "chart-version", // Specify the chart version you want to deploy fetchOpts: { repo: "https://repo.chart.url", // Specify the Helm repository URL that hosts the Kafka connector chart }, // Define any custom values you require for your Kafka connector configuration values: { /* ... */ }, }, { provider }); // Export the resulting resource's name export const kafkaConnectorName = kafkaConnectorChart.getResource("v1/Service", "kafka-connector");


    • In the example above, we begin by importing the required Pulumi libraries for Kubernetes (@pulumi/kubernetes) and Oracle Cloud Infrastructure (@pulumi/oci).

    • We then obtain the kubeconfig for the OKE cluster by referencing an existing cluster (oci.containerengine.Cluster.get). The OID must be provided for your specific OKE cluster.

    • A Kubernetes provider is instantiated, configured with the kubeconfig of the OKE cluster obtained earlier.

    • The k8s.helm.v3.Chart resource definition is where we deploy the Kafka Connector Helm chart. The chart parameter takes the name of the Helm chart, and version is for specifying the chart version. The fetchOpts.repo is the URL to the Helm repository where the Kafka Connector chart is stored. In the values object of this resource, you would specify the configuration options needed for the Kafka Connector – such as broker URLs, connector configurations etc.

    • Lastly, we export the name of the Service created by the Helm chart, which is useful to quickly see the name of the Kafka Connector Service after it is deployed.

    Remember, before you run pulumi up, you must ensure- you have access to the OCI account and have the correct permissions to deploy resources to the OKE cluster. Additionally, ensure that the Helm chart details like version and fetchOpts.repo point to valid and existing resources.
