1. Deploy the nublado2 helm chart on Opensshift

    TypeScript

    Deploying a Helm chart on an OpenShift cluster involves several key steps when using Pulumi:

    1. Setting up the OpenShift cluster: Before you can deploy a Helm chart, you need an existing OpenShift cluster. Pulumi can help you manage OpenShift clusters when using one of the supported cloud providers, such as AWS, Azure, or Google Cloud Platform. For this demonstration, we will assume that the OpenShift cluster is already running.

    2. Configuring the Kubernetes Provider for Pulumi: Pulumi requires an appropriate configuration to interact with your OpenShift cluster. This involves setting up the Kubernetes provider with the details of the cluster, including endpoint, credentials, and more.

    3. Deploying the Helm Chart: With the provider configured, you can use Pulumi's Chart resource from the kubernetes package to deploy Helm charts. This requires the name of the chart, the repository where the chart is located, and any custom values you want to provide to the Helm chart.

    Let's start with the TypeScript program. Please make sure that you have Pulumi installed and also have access to an OpenShift cluster. If you don't, please follow the OpenShift documentation to create a cluster and get the kubectl command-line tool configured to interact with your cluster.

    Pulumi TypeScript Program to Deploy a Helm Chart on OpenShift

    import * as k8s from "@pulumi/kubernetes"; // Step 1: Configure the Kubernetes provider to use the context of kubectl // which is configured to interact with your OpenShift cluster. const provider = new k8s.Provider("openshift", { kubeconfig: process.env.KUBECONFIG, // Ensure the KUBECONFIG env variable is set }); // Step 2: Define the Helm chart for nublado2. // You must provide the correct repository and chart name. const nublado2Chart = new k8s.helm.v3.Chart("nublado2", { chart: "nublado2", // Replace with the correct chart name if different version: "x.x.x", // Specify the exact chart version fetchOpts: { repo: "https://charts.example.com" // Replace with the correct Helm repo URL }, }, { provider }); // Export the base URL of the nublado2 application by querying the Service or Ingress // that the Helm chart would have installed and made available. export const baseUrl = nublado2Chart.getResourceProperty("v1/Service", "nublado2-service", "status") .apply(status => status.loadBalancer.ingress[0].hostname);

    This program specifically does the following:

    • Imports the @pulumi/kubernetes package which provides the Kubernetes resources.
    • Configures a Kubernetes provider that uses the context from the kubectl tool which is pre-configured to communicate with your OpenShift cluster.
    • Defines a Helm chart resource for nublado2.
    • Assumes the necessary Helm repository and chart name are provided correctly—that is, the repository where the nublado2 chart can be found and the chart version are both correct and valid.
    • Exports the base URL where the nublado2 application will be accessible. This assumes the Helm chart creates a service of type LoadBalancer and makes the application available at a specific URL which can be retrieved from the status of the Service resource.

    Important Notes

    • Replace "https://charts.example.com" with the actual Helm repository URL where the nublado2 chart is hosted.
    • Replace "nublado2" with the precise name of the Helm chart if it differs.
    • Set the version to the chart version you want to deploy.
    • The .apply(status => status.loadBalancer.ingress[0].hostname) part assumes that the service created by the Helm chart is of type LoadBalancer and that you're deploying to a cloud provider that supports LoadBalancer services. If that's not the case, you'll need to modify this to reference the correct attribute like a NodePort or an Ingress that the nublado2 service would expose.

    Once you have this program, you can run it using the Pulumi CLI:

    • Run pulumi up to preview and deploy the changes.
    • If you're satisfied with the preview, you can proceed with the actual deployment.
    • After the deployment finishes, Pulumi will output the base URL where nublado2 is running.

    Remember to handle your Kubernetes configuration securely and only keep it accessible in a secure environment, as it provides full access to your OpenShift cluster.
