1. Deploy the xos-gui helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the xos-gui Helm chart on Oracle Kubernetes Engine (OKE), we will perform the following steps using Pulumi:

    1. Set Up OKE: Provision an OKE cluster if you don't have one already.
    2. Install the Pulumi Kubernetes Provider: This provider allows Pulumi to interact with Kubernetes.
    3. Deploy the Helm Chart: Use the Pulumi Kubernetes provider to deploy the xos-gui chart on your OKE cluster.

    For the purpose of this guide, I will assume you have an existing OKE cluster and you already have the necessary kubeconfig file to interact with it.

    We will use the kubernetes package, which provides the helm.v3.Chart resource to deploy Helm charts onto a Kubernetes cluster.

    Below is a TypeScript program which accomplishes the deployment:

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

// Create a reference to the existing OKE cluster using the kubeconfig provided by Oracle Cloud Infrastructure
const cluster = new k8s.Provider("okeCluster", {
    kubeconfig: "<Your-Kubeconfig>", // Ensure you replace <Your-Kubeconfig> with your actual kubeconfig data
});

// Deploy the xos-gui Helm chart.
const xosGuiChart = new k8s.helm.v3.Chart("xos-gui", {
    chart: "xos-gui",
    // You would typically use the `version` property to pin the chart version.
    // version: "1.0.0",
    // Specify the Helm repository URL if it is not from a public Helm repo.
    // fetchOpts: { 
    //     repo: "https://helm.repo.url/"
    // },
}, { provider: cluster });

export const xosGuiChartStatus = xosGuiChart.status;

    Here's what each part of the program does:

    • Provider Instantiation: We instantiate a Kubernetes provider by referring to the existing kubeconfig for the OKE cluster. The kubeconfig contains the necessary information to communicate with your OKE cluster.

    • Helm Chart Deployment: The k8s.helm.v3.Chart resource facilitates the deployment of the chart to the cluster referred to by the provider. In this example, we pass the name xos-gui as the name of the Helm chart to be deployed. You'll need to provide the proper Helm chart name and optionally, the repository URL where the Helm chart is located if it’s not a public one included in the Helm client’s default list of repositories.

    • Exporting: We export the status of the Helm chart deployment, which can be helpful to examine the chart's status directly from the Pulumi stack outputs.

    To run this Pulumi program, ensure you have Pulumi installed and configured for TypeScript, and then execute the usual Pulumi commands to deploy your infrastructure:

    1. Initialize a new Pulumi project with pulumi new.
    2. Save the above TypeScript code into a file named index.ts.
    3. Run npm install to install any necessary dependencies.
    4. Run pulumi up to apply the program and deploy the Helm chart on your OKE cluster.

    Please replace "<Your-Kubeconfig>" with the actual kubeconfig content from your OKE cluster. This should not be checked into source control if it's a personal or private cluster, and you should manage this securely as it provides administrative access to your cluster.
