1. Deploy the go-application helm chart on Opensshift


    To deploy a Helm chart on an OpenShift cluster using Pulumi, you would typically use the kubernetes.helm.v3.Chart resource from the Kubernetes provider. This resource allows you to deploy a Helm chart from a variety of sources, including a Helm repository or a local directory.

    The Helm chart for a Go application can be deployed by specifying the appropriate chart name and repository details. If the Helm chart is hosted in a public repository, you need to provide the URL to the repository. If the Helm chart is available locally, you can provide the path to the directory containing the chart files.

    Below is a TypeScript program for Pulumi that demonstrates how to deploy a Go application using a Helm chart on an OpenShift cluster. Please ensure that you have the appropriate access configured to the OpenShift cluster and the kubectl tool is set to use the correct context.

    import * as k8s from "@pulumi/kubernetes"; // This program assumes you have access to an OpenShift cluster and `kubectl` is using the correct context. // Create a Helm chart resource that represents the Go application. // Replace `chartRepoUrl` with the URL of the repository where the Go application Helm chart is located. // Replace `chartVersion` with the version of the chart you want to deploy. // Replace `goApplicationReleaseName` with the preferred release name for your Go application. // Replace `namespace` with the target OpenShift namespace where you want the application to be deployed. const goApplicationChart = new k8s.helm.v3.Chart("go-application", { chart: "go-application", version: "chartVersion", // specify the chart version here fetchOpts: { repo: "chartRepoUrl", // specify the Helm repository URL here }, namespace: "namespace", // specify the OpenShift namespace here // You can provide custom values to the chart by providing a `values` object // values: { // key1: value1, // key2: { // subkey: subvalue, // }, // }, }, { provider: openShiftProvider }); // You can export the status URL or any other output of your Go application // For example, if your Go application chart exposes a `statusUrl`, you can export it like this: // export const goAppStatusUrl = goApplicationChart.getResourceProperty("v1/Service", "go-application-service", "status").apply(status => status.loadBalancer.ingress[0].ip); // Note: The `openShiftProvider` should be configured for your OpenShift cluster, and it is assumed to be declared outside of this code snippet.

    Make sure to replace the placeholder values (chartRepoUrl, chartVersion, goApplicationReleaseName, and namespace) with the actual values relevant to your Go application Helm chart.

    The example also shows how you could export values from the deployed chart, such as a status URL, if the chart creates Kubernetes resources that expose such details.

    This Pulumi program provides the basic configuration to deploy a Helm chart. Depending on your exact requirements, you might have to provide additional configuration parameters inside the values field of the k8s.helm.v3.Chart constructor.

    Before running your Pulumi code, install the required Pulumi package(s) with the following command:

    npm install @pulumi/kubernetes

    To run the Pulumi program, simply execute it using the Pulumi CLI with:

    pulumi up

    After reviewing the proposed changes and confirming they're acceptable, select yes to start the deployment.

    For more detailed information on deploying applications on OpenShift with Pulumi, you can refer to the Pulumi Kubernetes API documentation which includes information on the kubernetes.helm.v3.Chart resource used in the code above.
