1. Deploy the zimagi-lib helm chart on Opensshift

    TypeScript

    Deploying a Helm chart into an OpenShift cluster involves a few steps. Below is a general overview of the process along with a TypeScript program using the Pulumi Kubernetes provider. This example assumes that you have already set up access to your OpenShift cluster and have the necessary context configured in your local kubeconfig file.

    Here's a step-by-step guide to the code:

    1. First, import the necessary Pulumi and Kubernetes packages.
    2. Then, create an instance of the Chart class from the Pulumi Kubernetes package. The Chart resource is a component resource that represents a collection of Kubernetes resources as defined by a Helm Chart. It can be deployed into a Kubernetes cluster using kubectl apply, and Pulumi automates this process.

    In the constructor of the Chart class, you define:

    • The chart parameter, which specifies the name of the Helm chart.
    • The version parameter, which specifies the version of the Helm chart. (optional)
    • The values parameter, which allows you to overrule the default values provided by the Helm chart with your own values. (optional)
    • The fetchOpts parameter, where you can specify the repository if the Helm chart comes from a Helm repository other than the default one.

    Please replace "YOUR_NAMESPACE" with the namespace you want to deploy to in OpenShift, and "HELM_REPO_URL" with the URL of the Helm repository where the zimagi-lib chart is located, if it's not a chart from the default Helm repository.

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

// Deploying a Helm chart on OpenShift cluster
const zimagiLibChart = new kubernetes.helm.v3.Chart("zimagi-lib-chart", {
    // Replace `YOUR_NAMESPACE` with your target namespace in the OpenShift cluster
    namespace: "YOUR_NAMESPACE",
    // Assuming 'zimagi-lib' is the chart name; specify the version if needed
    chart: "zimagi-lib",
    // Specify the repository URL where 'zimagi-lib' chart can be found
    // Replace `HELM_REPO_URL` with the URL to your Helm chart's repository
    fetchOpts: {
        repo: "HELM_REPO_URL",
    },
    // Include any custom values (overriding default values in the chart) here
    values: {
        // For example, set a custom value:
        // someCustomValue: "custom-setting",
    },
});

export const chartName = zimagiLibChart.metadata.name;

    This code block would create a new Helm chart deployment in your OpenShift cluster. The export at the end of the program is used to output the name of the deployed chart so you can quickly reference it using Pulumi CLI commands, such as pulumi stack output chartName.

    To run this Pulumi program:

    1. Ensure Pulumi CLI and kubectl are installed.
    2. Set up your Pulumi stack and select your OpenShift environment.
    3. Place the TypeScript code into a file named index.ts.
    4. Run pulumi up to preview and deploy the resources.

    Remember to replace placeholder strings like "YOUR_NAMESPACE" and "HELM_REPO_URL" with actual values before running the program. If the chart requires additional values for the configuration, define them in the values field.
