1. Deploy the voltha-stack helm chart on Opensshift


    Deploying a Helm chart on an OpenShift cluster using Pulumi involves several steps. First, you'll need to have an existing OpenShift cluster. Then, using Pulumi with the Kubernetes provider, you'll configure your Pulumi program to use the cluster's kubeconfig for authentication. With access to the cluster, you can then deploy Helm charts.

    Below is a Pulumi program that will deploy a Helm chart, which in your case would be the voltha-stack chart, on an OpenShift cluster. This program assumes that you have an existing OpenShift cluster and the necessary permissions to deploy resources to it. The kubeconfig file will be used for authentication, so ensure it's correctly set up in your environment.

    We'll use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider which is designed to manage Helm Charts in a declarative way.

    Here is a detailed program in TypeScript:

    import * as k8s from "@pulumi/kubernetes"; // Initialize a Kubernetes provider with the OpenShift kubeconfig. // This tells Pulumi how to communicate with your OpenShift cluster. const openshiftProvider = new k8s.Provider("openshiftK8s", { kubeconfig: process.env.KUBECONFIG, // Ensure the KUBECONFIG environment variable is set }); // Deploy the voltha-stack Helm chart to the OpenShift cluster. // The `Chart` resource requires the name of the chart and the repository where the chart is located. // If you have a private repository or require other customization, you can specify additional options. const volthaStack = new k8s.helm.v3.Chart( "voltha-stack-chart", // This is the Pulumi resource name. { // Depending on where the chart is hosted, and if you need a specific version, // specify the `repo` and `chart` properties accordingly. // For demonstration purposes, I've used placeholders. chart: "voltha-stack", version: "1.0.0", // Specify the version of the chart you wish to deploy. fetchOpts: { repo: "https://charts.example.com/voltha", // Replace with the actual Helm repository URL. }, }, { provider: openshiftProvider } // Use the OpenShift provider to manage this resource. ); // Export the URL of the deployed application (if applicable). export const applicationUrl: string = volthaStack.getResourceProperty( "v1/Service", // Assuming the chart contains a Service object. You may need to modify this. "voltha-service", // Replace with the actual Service name from the chart. "status.loadBalancer.ingress[0].hostname" // Adjust the property path according to the Service manifest. );

    To explain:

    1. We import the Kubernetes package provided by Pulumi for TypeScript.
    2. We create an instance of a Kubernetes Provider. This will allow Pulumi to use our OpenShift kubeconfig file for authenticating with the cluster.
    3. We deploy the voltha-stack Helm chart. You will need to replace the placeholders with actual values, such as the version number and repository URL, depending on the chart details.
    4. We export the application URL, which you can access with the Pulumi CLI after deployment, to confirm that the service is reachable. Note that the specific resource and property to export may change according to the actual content of the Helm chart.

    Please ensure the Helm chart details (like chart, version, repository) and kubeconfig are correctly set up before running the program. After writing this TypeScript program in a file (for example, index.ts), you can deploy it using the Pulumi command-line tool following standard Pulumi workflow (pulumi up).
