1. Deploy the yace-exporter helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the yace-exporter Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you need to complete several steps:

    1. Set up an Oracle Kubernetes Engine (OKE) cluster if you don't already have one.
    2. Ensure you have kubectl configured to communicate with your OKE cluster.
    3. Write a Pulumi program to deploy the yace-exporter Helm chart.

    Below is a Pulumi TypeScript program that demonstrates how to deploy a Helm chart to an existing OKE cluster. This program assumes you already have an OCI (Oracle Cloud Infrastructure) Kubernetes cluster available and kubectl is set up to interact with that cluster.

    The program uses the oci.ContainerEngine.Cluster resource to represent your existing cluster. You use the kubernetes.helm.v3.Chart resource from the @pulumi/kubernetes package to represent the Helm chart deployment.

    Before you run the Pulumi program, ensure:

    • You have Pulumi CLI installed and logged in to your account.
    • You have the required OCI credentials for Pulumi to manage resources in your Oracle Cloud Infrastructure.

    Here's the detailed Pulumi TypeScript program:

    import * as pulumi from '@pulumi/pulumi';
import * as k8s from '@pulumi/kubernetes';

// Retrieve an existing Kubernetes cluster managed by Oracle's Container Engine for Kubernetes (OKE).
// Replace `<cluster-id>` with your actual cluster ID.
const cluster = oci.ContainerEngine.Cluster.get("existing-cluster", "<cluster-id>");

// Pull OCI config to interact with the OKE cluster from Pulumi configuration
// Store the kubeconfig information for your cluster, which should be securely retrieved from your infrastructure
// For example purposes, we use a placeholder. Replace this with the kubeconfig content
const kubeconfig = pulumi.output('<Insert your kubeconfig here>');

// Create a provider instance using the kubeconfig obtained from your OKE cluster
const provider = new k8s.Provider("oke-k8s", {
    kubeconfig: kubeconfig,
});

// Deploy the yace-exporter Helm chart
const chart = new k8s.helm.v3.Chart("yace-exporter", {
    chart: "yace-exporter", 
    version: "latest", // Specify the chart version you want to deploy.
    fetchOpts:{ 
        repo: "https://<repository-url>", // Replace with the URL of the Helm repository containing the yace-exporter chart
    },
}, { provider: provider });

// Export the name of the chart
export const chartName = chart.metadata.name;

    This program does the following:

    • Imports essential packages @pulumi/pulumi for the Pulumi core functionality and @pulumi/kubernetes to interact with Kubernetes clusters and resources.
    • Retrieves information of an existing OKE cluster using the oci.ContainerEngine.Cluster resource. You need to provide the cluster ID.
    • Initializes a new Kubernetes provider to interact with the OKE cluster, using the kubeconfig from the Oracle Cloud.
    • Deploys the yace-exporter Helm chart to the cluster using the k8s.helm.v3.Chart resource. The name of the chart and the repository URL are placeholders in this code, and you need to replace them with the actual Helm chart name and the URL of the Helm repository.

    After preparing the code above, execute it with the Pulumi CLI:

    1. Run pulumi up to preview and deploy the changes.
    2. After examining the preview, if everything looks good, confirm the deployment by selecting yes.

    Pulumi will then carry out the actions described in the program and deploy the Helm chart to your OKE cluster. You can manage and monitor the deployment through the Pulumi CLI or Pulumi Console.
