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

    TypeScript

    To deploy the oracledb-exporter Helm chart on Oracle Kubernetes Engine (OKE), you'll need to take a series of steps using Pulumi:

    1. Set Up the OKE Cluster: The first step is to create or configure an existing OKE cluster, where your Helm chart will be deployed.

    2. Install the Helm Chart: Once you have an OKE cluster, you will install the Helm chart for oracledb-exporter on it.

    Below is a Pulumi program that demonstrates how to perform these steps using TypeScript.

    Prerequisites

    Make sure you have the following prerequisites met before running the code:

    • You've installed Pulumi CLI and set up the Pulumi project.
    • You have access to an Oracle Cloud Infrastructure (OCI) account and have the necessary permissions to manage OKE clusters and deploy Helm charts.
    • You have configured your OCI credentials for use with Pulumi. If needed, you can refer to the Pulumi OCI documentation on how to do this.

    Pulumi Program to Deploy oracledb-exporter on OKE

    import * as pulumi from '@pulumi/pulumi'; import * as oci from '@pulumi/oci'; import * as kubernetes from '@pulumi/kubernetes'; // Step 1: Create or configure your OKE cluster // Using a previously configured OKE cluster here. If you need to create a new OKE cluster, you can use the oci.ContainerEngine.Cluster resource. // Make sure to replace `yourExistingClusterId` with the actual OCI ID of your OKE cluster. const clusterId = 'yourExistingClusterId'; // TODO: replace with the actual cluster ID const kubeconfig = oci.containerengine.getClusterKubeconfig({ clusterId: clusterId, }); // Step 2: Use a Kubernetes Provider to interact with the OKE cluster const k8sProvider = new kubernetes.Provider('oke-k8s', { kubeconfig: kubeconfig.then(kc => kc.content), }); // Step 3: Install the Helm chart for oracledb-exporter const oracledbExporterChart = new kubernetes.helm.v3.Chart('oracledb-exporter', { chart: 'oracledb-exporter', // Replace with the actual Helm repository URL or name where the oracledb-exporter chart is located fetchOpts: { repo: 'https://helm-repository-url/', // TODO: replace with the actual Helm repo URL }, // Provide any custom values.yaml file or override parameters necessary for the oracledb-exporter Helm chart values: { // Define necessary values or custom configuration for oracledb-exporter }, }, { provider: k8sProvider }); // Optional: Output the status of the deployed chart export const oracledbExporterStatus = oracledbExporterChart.status;

    This program assumes that you've already set up an OKE cluster and have its ID available. If you're starting from scratch and need to create an OKE cluster, you can include that in your Pulumi program using the oci.ContainerEngine.Cluster class (an example can be found in the OCI Pulumi documentation).

    The oracledb-exporter Helm chart is then installed on your OKE cluster using the kubernetes.helm.v3.Chart class. Please remember to replace the placeholder for the repo property in fetchOpts with the actual Helm repository where the oracledb-exporter chart can be found. Similarly, you'd need to fill in the values property with any specific configurations your exporter needs (like connection strings, credentials, etc.).

    Finally, we output the status of the deployed Helm chart, which can give you preliminary information on whether the deployment was successful.

    You'd run the program with the following Pulumi CLI commands:

    pulumi up

    This will provision the resources as described in the code. Make sure to review the changes that Pulumi plans to make before confirming the deployment. After the deployment is successful, you will get outputs of any exported values like the status of the Helm chart deployment.
