1. Deploy the datadog_helpers helm chart on Oracle Kubernetes Engine (OKE)


    Deploying the datadog_helpers Helm chart on Oracle Kubernetes Engine (OKE) involves several steps. We will use Pulumi's Kubernetes library to make it easier. Before you start, you should have Pulumi installed, along with access to an OCI (Oracle Cloud Infrastructure) account and have the OCI CLI configured on your machine.

    Here's a step-by-step guide to deploy a Helm chart on OKE using Pulumi with TypeScript:

    1. Set up OKE: Start by creating an OKE cluster. To manage resources in OCI with Pulumi, we use the oci package.

    2. Install the Helm Chart: With the kubernetes package, we can use the Chart resource to deploy Helm charts.

    Here is the Pulumi program written in TypeScript which you can use to deploy the datadog_helpers Helm chart on Oracle Kubernetes Engine:

    import * as pulumi from "@pulumi/pulumi"; import * as kubernetes from "@pulumi/kubernetes"; import * as oci from "@pulumi/oci"; // Create an OCI provider to interact with your Oracle Cloud Infrastructure. const ociProvider = new oci.Provider("oci", { region: "us-phoenix-1", // Replace with your OCI region }); // Assuming you have already created an OKE cluster and have the kubeconfig file // for connecting to your Kubernetes cluster. In a real-world scenario, you would use // Pulumi to create and manage the OKE cluster as well, but for brevity, we'll assume // the cluster is already set up. const kubeconfig = "<your-kubeconfig-content-here>"; // Create a Pulumi Kubernetes provider that uses your kubeconfig. const k8sProvider = new kubernetes.Provider("oke-k8s", { kubeconfig: kubeconfig, }); // Deploy the `datadog_helpers` Helm chart using the Kubernetes provider. const datadogHelpersChart = new kubernetes.helm.v3.Chart("datadog-helpers", { chart: "datadog_helpers", version: "1.0.0", // Specify the chart version you want to deploy fetchOpts: { repo: "https://helm.datadoghq.com", // Replace with the correct Helm repo URL }, }, { provider: k8sProvider }); // Export the name of the chart deployment export const chartName = datadogHelpersChart.metadata.apply(meta => meta.name);

    This Pulumi program does the following:

    • Imports necessary libraries for Pulumi, Kubernetes, and OCI.
    • Creates a provider to interact with the OCI services.
    • Assumes that you already have access to a Kubernetes cluster created in OKE, using the kubeconfig file to interact with it.
    • Creates a Pulumi Kubernetes provider that understands how to communicate with the OKE cluster via the kubeconfig file.
    • Deploys the datadog_helpers Helm chart to the cluster by specifying the chart name, version, and fetching the chart from the Datadog Helm repository.
    • Finally, the program exports the name of the deployed chart for your reference.

    To run this Pulumi program:

    1. Place the above code into a file named index.ts.
    2. Open your terminal and navigate to the same directory as your index.ts file.
    3. Run pulumi up to preview and deploy your changes.

    The pulumi up command will prompt you for confirmation before proceeding to modify your infrastructure. Once you approve it, Pulumi will communicate with OCI to deploy the specified Helm chart onto your Oracle Kubernetes Engine cluster.

    Please ensure you replace placeholder values like <your-kubeconfig-content-here> with actual values from your environment. You should securely handle your kubeconfig file as it contains sensitive information that grants access to your Kubernetes cluster.
