1. Deploy the couchbase-monitor-stack helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the Couchbase monitoring stack Helm chart on Oracle Kubernetes Engine (OKE), you're required to do a few things:

    1. Set up an Oracle Kubernetes Engine (OKE) cluster.
    2. Install the Helm CLI tool, which is used to manage Kubernetes applications.
    3. Add the appropriate Helm chart repository which contains the "couchbase-monitor-stack" chart.
    4. Use the Pulumi kubernetes package to deploy this Helm chart onto your OKE cluster.

    Below is a step-by-step TypeScript program using Pulumi which deploys the Couchbase monitoring stack onto an existing OKE cluster. Assuming you have already provisioned an OKE cluster, you'll need to obtain the necessary kubeconfig file that allows you to interact with your Kubernetes cluster.

    Here is a Pulumi program written in TypeScript that demonstrates these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Before running this program, ensure you've configured your kubeconfig // file so Pulumi can communicate with your OKE cluster. // The kubeconfig can often be found at `~/.kube/config`. // Create a new k8s provider that uses the kubeconfig from your OKE Cluster. const okeK8sProvider = new k8s.Provider("oke-k8s-provider", { kubeconfig: pulumi.interpolate`${process.env.KUBECONFIG}`, }); // Define the Helm chart version and repository details for the Couchbase monitoring stack. const couchbaseMonitorStackChartVersion = "x.y.z"; // Specify the correct version of the Chart. const couchbaseMonitorStackRepoUrl = "https://couchbase-partners.github.io/helm-charts/"; // Use the official Couchbase Helm charts repository. // Deploy the Couchbase monitoring stack Helm chart using the k8s provider. const couchbaseMonitoring = new k8s.helm.v3.Chart("couchbase-monitor-stack", { chart: "couchbase-monitor-stack", version: couchbaseMonitorStackChartVersion, fetchOpts: { repo: couchbaseMonitorStackRepoUrl }, }, { provider: okeK8sProvider }); // Export any important information about the deployment, perhaps the chart name or version. export const chartName = couchbaseMonitoring.metadata.name; export const chartVersion = couchbaseMonitoring.metadata.version;

    In this program, you will notice that there's an expected environment variable KUBECONFIG. This variable should point to your kubeconfig file for the OKE cluster. Usually, this file can be downloaded from your OCI (Oracle Cloud Infrastructure) console after setting up the Kubernetes cluster.

    The kubernetes.helm.v3.Chart Pulumi resource is used to deploy Helm charts. The chart property specifies the name of the Helm chart "couchbase-monitor-stack", whereas the version and fetchOpts properties ensure the correct version of the chart is fetched from the official Couchbase Helm charts repository.

    Remember to replace "x.y.z" with the actual version number of the Couchbase monitoring stack chart you intend to deploy.

    Once you run this Pulumi program by executing pulumi up in your development environment, Pulumi will provision the Helm chart on your OKE cluster, effectively deploying the Couchbase monitoring stack. You can verify the deployment by using the kubectl command-line tool to see the resources it created.
