1. Deploy the infrastructure-alerts helm chart on Oracle Kubernetes Engine (OKE)


    To deploy the infrastructure-alerts Helm chart on Oracle Kubernetes Engine (OKE), we will use the Pulumi Kubernetes provider. This provider allows us to interact with Kubernetes clusters of different cloud providers, including Oracle Cloud Infrastructure (OCI).

    Here's how you can use Pulumi with TypeScript to deploy a Helm chart to OKE:

    1. Oracle Kubernetes Engine Cluster: You need an existing Kubernetes cluster on OKE. Pulumi can create this for you, but for simplicity, let's assume that the cluster is already provisioned and kubeconfig is set up accordingly on your local machine to interact with the cluster.

    2. Helm Chart: The Helm chart named infrastructure-alerts should be located in a Helm repository or have its package ready for deployment.

    3. Pulumi Kubernetes Provider: We use this provider to interact with Kubernetes. Ensure that the Pulumi CLI is installed and configured with access to your Kubernetes cluster.

    Here is a step-by-step TypeScript program to deploy the specified Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Define the settings of the Helm chart const chartName = "infrastructure-alerts"; const chartVersion = "1.0.0"; // Specify the exact chart version you want to deploy const helmRepoUrl = "https://charts.example.com/"; // The URL to the Helm repository const releaseName = "infrastructure-alerts-release"; // Assuming we have configuration settings for the namespace and possible chart values in a Pulumi config const pulumiConfig = new pulumi.Config(); const namespace = pulumiConfig.require("namespace"); // The target namespace for the Helm release const chartValues = pulumiConfig.getObject<any>("chartValues") || {}; // Additional configuration values for the chart // Create a Helm release using the `infrastructure-alerts` chart const helmChart = new k8s.helm.v3.Chart(releaseName, { chart: chartName, version: chartVersion, fetchOpts: { repo: helmRepoUrl }, namespace: namespace, values: chartValues, }); export const chartStatus = helmChart.status;

    In this program:

    • We've imported the k8s module from Pulumi's Kubernetes package, which gives us access to Helm-related classes and functions.
    • We've specified the chart name, version, and repository URL. Make sure to replace https://charts.example.com/ with the actual URL of the repository where the infrastructure-alerts Helm chart is hosted.
    • We've set up an instance of Pulumi's Chart class, which represents a Helm chart that can be deployed into a Kubernetes cluster. The Chart resource will install the Helm chart from the specified repository and version.
    • We use pulumi.Config to get configuration settings that include the namespace and any additional values that you want to provide to the Helm chart.
    • An export is defined to output the status of the Helm release. Once deployed, you can view the status in the Pulumi console or through the pulumi stack output command.

    Before running this Pulumi program, ensure:

    • You have Pulumi CLI installed and configured for your OCI account and Kubernetes cluster.
    • You have access to the kubeconfig file that allows you to interact with your OKE cluster.
    • You replace the infrastructure-alerts chart name and version with the actual ones you intend to use.

    To run this program:

    1. Create a new directory for your Pulumi app.
    2. Run pulumi new typescript in the directory and follow the prompts.
    3. Replace the contents of index.ts with the code provided above.
    4. Replace placeholder strings with actual values specific to your use case.
    5. Run pulumi up to execute your Pulumi program and deploy the Helm chart to OKE.

    Pulumi will handle the deployment process, and you'll be able to see the live updates in your terminal or the Pulumi dashboard. After the deployment has completed successfully, you can check your Kubernetes cluster to verify that the Helm chart has been deployed.
